1. Marking width: the international general standard of road marking width is 15 cm. But considering the road marking machine may be applied in parking lots, communities, etc, so it is wise to purchase marking machines with adjustable marking width, it will help you to rationally use and save the paint. The general adjusting range is from 5 to 15 cm.
2. Paint classifications: the often used paints are water-soluble type and solvent type. If your road marking machine can adopt both paints, you can make your business scope expanded to sports turf and other places.
3. Hand holding spray gun: it allows you to freely spray marks on the ground, stand columns and other places. The hand holding spray gun has gradually become the one of the standard outfits.
4. Cleaning system: Some of the road marking machines are equipped with an auto-clean system. It quickly cleans the pipe system after work, to make your cleaning time cut to half.
5. The Reflective Glass Beads: Road construction companies should also consider the glass beads spray system because some countries take the glass beads into their standards.
6. Curve marking: some road marking machines have an additional wheel in the rear to let the operator turn the machine when working at turns or intending to spray fancy lines.

Are there too many road marking equipment to choose from? Don't worry, if you get a road marking work, but not familiar with the road marking industry, please click here, tell us which paint do you use and where do you want to mark, leave your name, email and message to us, we will give you the professional solution in 24 hours. Or you can read the following of this article to learn more about the road marking industry and pick out the right road marking equipment for you.
If you want to do a road marking works, firstly, you need to figure out the following questions.
1.The Paint
In different countries or regions, there are different standards of road marking paints. You can buy very many different road marking paints in the market, these paints can be divided into three basic categories: thermoplastic, cold solvent ( water based ), two-component.
2.The Volume
For example, the total length of road marking lines, the period of construction.
3.The Line Type
Common line type include solid, dashed, zebra crossing, vibrating (convex) lines.
convex road lines marking
Under the applicable paints, we divide our road marking machines into three categories: thermoplastic road marking machine, cold paint road marking machine and two-component road marking machine. In each category, according to the construction efficiency, we divide our road marking machines into three types: driving-type > self-propelled > hand-push, the driving-type has three size: big > middle > small. You can choose the right machine according to the volume of your work. For example, if you have a long highway that need to mark, using thermoplastic paint, you'd better buy a AC-BTSC big size driving-type thermoplastic road marking machine.
In addition, if you use thermoplastic road marking paint, in addition to the thermoplastic marking machine, you'd better buy a pre-heater. Pre-heaters are matched with thermoplastic road marking machine and used for melting thermoplastic paint, saving fuel energy and heating time, improving the construction efficiency.
Generally, our road marking machine can do both the solid line and the dashed line, if you want to do the vibrating (convex) lines, you just need to change the marking shoe. We designed some special road marking equipment, AC-SPTP and AC-HPTP, to do the zebra crossing.
We also supply some auxiliary equipment, the auxiliary equipment can effectively reduce the overall cost of the road marking construction, improve the road marking construction efficiency and quality, increase the road marking construction safety and environmental protection.

A pavement marking machine is normally composed of engine, air compressor, paint bucket(kettle for heating and melting paint), spray gun, guide rod, controller, die shoe, dispenser and other devices. Driving carrier to provide power is also a must.
Engine
Most of roadway striping equipment adopt engine as the driving force, while some use battery or liquefied gas. The power range of the appliable engines is about 2.5HP to 20HP. Generally speaking, the better the engine, the better the performance of entire marker device. If adopting the battery as the driving force, the running time each charge shall not be less than 7 hours.
Air Compressor
Air compressor is also one of the main parts that affect the performance for the whole line marking machine, especially for those conducting spraying by air pressure. Overall, The bigger the emission of air compressor, the better the performance of marking equipment.
Paint Bucket
In terms of line making machine, paint bucket has two main functions. One is to carry the molten paint; the size of its capacity will affect the progress of operation. The other function is as a pressure vessel, which can become the driving force of the striping work. In this sense, the sealing, safety, corrosion resistance are the important properties that the user should be concerned.
Spray Gun
Using the hand-held spray gun not only allows you to freely use the template to paint various symbols, but also can work on walls, columns and other places other than the ground. Hand-held spray guns have gradually become the standard configuration of various marking equipment.
Cleaner
Some strip marking devices are equipped with an automatic cleaner, which can quickly clean the pipeline system after each end of work, your cleaning work can therefore save more than half of the time.
Glass Bead Spreader
The road maintenance company should also consider configuring the glass bead spreader as a standard configuration. The spreader can spray glass beads to make the marking construction fully meet the higher requirements.
Glass bead, a kind of colorless and transparent ball, has function of light refraction. Glass bead mixed in the coating or dispensed throughout the coating surface can reflect car light back to the driver's eyes, thus greatly improving the visibility of marking lines. The headlights flash on such marking lines can reflex back in parallel, so the driver could see the forward way clearly and the security is thus raised at night.

Based on the different driving modes, which is also a typical classification principle, all the pavement stripe markers can be categorized into hand-push type(also called walk behind stripping machines), self-propelled type, driving-type, and truck-mounted type.
Based on the marking paint applied on paved roadways, all the road marking machines could fall into two major sorts, thermoplastic paint pavement marking machines and cold paint airless pavement marking machines.
Thermoplastic pavement marking machine is low-pressure air spraying machine with high-efficiency and flexibility. It can serve long distance and continuous line marking work. The spray thickness is adjustable and not effected by the old marking line. A hot melt kettle inside the machine plays a vital role in heating, melting, and stirring thermoplastic marking paints. The coating only needs a few minutes to harden after cooling fast from 200℃. Thermoplastic paints can be produced in any colour, but when it comes to the road marking, yellow and white are the most common colours.
Thermoplastic road marking machine
Cold paint or cold plastic airless pavement marking machine is a kind of airless cold and tow-component machine. Large capacity paint tank and glass beads bin make it suitable for long distance and continuous marking work. Cold solvent blacktop marking paint is made of modified acrylic resins, pigment filling and additive, generally used in city roads and common roads consisted of asphalt pavement and concrete road surface; it has excellent weather resistance, high toughness, strong wear resistance and adhesion, and it is not easy to peel off. The called cold here actually refers to the normal temperature, without a physical cooling course involved in. So, since no heating and melting course is needed, this kind of road marking machine, whether it's driving-type or truck-mounted, enjoys much more efficiency.
Cold paint or cold plastic airless pavement marking machine
Two-component line marking machine is a high-end marking equipment that has emerged in recent years. Unlike thermoplastic marking facility and cold paint airless pavement marking equipment which coat the road with paint film through physical drying methods such as temperature drop or solvent volatilization, the two-component marking is a new type of striping device that forms a coating film by internal chemical cross-linking.
Cold paint or cold plastic airless pavement marking machine
Based on the purposes of usage, in a broad sense, road line removal machines should be included in this scope. As opposed to the pavement striping devices, road line removal machines are specialized for clearing away the broken, stained and wrong marking lines. Removing existing road striping or pavement markings is a real challenge. It's not easy to remove the traffic markings without causing damage to or scar the road surface. Built-in powerful cutter or grinder is the best method for removing traffic paint, thermoplastic, epoxy coatings and other materials. With the depth adjuster device, the removal machines can accurately adjust and fix depth according to the needs.

Road striping pre-heater, a specialized auxiliary machine, is matched with thermoplastic road marking machine. Its function lies in heating and melting thermoplastic paint, helps saving fuel energy and heating time, and improves the efficiency.

First, put the paint into the thermal insulation bucket for melting, and then introduce the melted liquid thermoplastic paint into the marking hopper and keep it in a flowing status. When starting to draw the line, put the marking hopper on the road, leaving a certain gap between the marking hopper and the ground. When the marking machine moves straight forward at a constant speed, it will automatically delineate a neat marking line. The glass bead spreader can automatically and evenly spread a layer of reflective glass beads on the marking line.

Briefly, In terms of thermoplastic type machine, at first we need heating and mix the paint within the thermoplastic pre-heater, and then put the paint into the paint tank of thermoplastic type device, than we can drive this machine to mark line: Paint from the paint tank out, after crossed the marking shoes, ultimately falls on the road.
In terms of cold paint type machine, we needn’t heat and mix the paint. Only put the paint into paint tank of cold paint type machine, than we can drive this machine to mark line: Paint is pumped from the paint tank, after crossed the marking shoes, ultimately falls on the road.

Road marking machine is a kind of device specially used to delineate diverse traffic lines on blacktop or concrete surface in order to offer guidance and information to motorists and pedestrians. Regulation for parking and stopping can also be indicated by the traffic lanes. Line marking machines conduct their work through screeding, extruding, and spraying thermoplastic paints or cold solvent paints on to the pavement surface.

the total cost for a concrete plant depends on its type (ready mix, central mix, mobile/stationary, production capacity, the current cost of raw materials and other expenses like labor and estimated hours in operation. Location sometimes imposes influences on it as well. Some crucial factors you'll need to account for are listed as follows.
1. Production Capacity
The production capacity of concrete mixing plant is different, the cost that needs to be invested is different. One is the device itself. The greater the production capacity of the equipment, the higher the procurement cost; second, the different production capacity means that the demand for raw materials such as cement, gravel, sand, and fly ash is different, which will lead to an increase in the capital investment of the entire project. The production capacity of concrete mixing plants for small and medium-sized projects is below 90m³/h, and the production capacity of concrete mixing plants required for large-scale production is usually 120m³/h-270m³/h.
2. Type and Model
To invest in a concrete mixing plant, you must first determine what type and model of equipment you need. The prices of different concrete mixing plants are different, and the gap is not small. Customers can choose the equipment model according to their actual situation, choose the model and choose the cost-effective equipment.
3. Site Construction Expense
In addition to the concrete manufacturing equipment, the initial investment required to set up a concrete plant also includes the cost of the site, the construction of office buildings and dormitories, and the cost of building a closed material yard in order to meet environmental protection standards.
4. Operation Cost
The later operation of the concrete mixing plant includes water and electricity costs, personnel wages, raw material procurement costs, loaders, and concrete transportation vehicles, which should be considered before investment.
5. Various Handling Fees
Investing in a concrete batch plant requires going through various procedures, and these procedures are also costly. These also need to be budgeted as the investment cost of building the mixing plant.
There is another point that needs to be paid attention to.
The investment cost of commercial concrete batching plant is higher than general engineering concrete mixing plant. The engineering concrete mixing station shall meet the needs of the project, and unnecessary functions can be discarded, as long as the quality of the concrete meets the needs of the project. The commercial concrete batching plant must be able to produce concrete with a variety of common labels，and sometimes needs to meet the special needs of users. The control system needs to be fully automatic, and it also needs to have a storage function in order to improve work efficiency.

Concrete batching plants are divided into different types. Plants are generally divided into stationary concrete batching plants and mobile concrete batching plants. This is a basic classification that many manufacturers distinguish at the time of production.
![[Image: 1055433265.jpg]](http://www.hmconcreteplant.com/uploadfile/201804/3/1055433265.jpg)
Stationary Concrete Plants
Stationary concrete plants are used to supply concrete to construction sites in large quantities.
This type of plant does not require specific space on the site to store materials, limiting the risk of damage. Also, factory-type stationary concrete plants ensure high-quality concrete production per requirements without the risk of material dosage errors.
Besides, factory-type concrete batching plants carry out various material quality checks throughout the concrete manufacturing process. On the other hand, they involve a delivery time linked to routing by a mixer truck, more accessible access to the site, and rapid implementation.
Mobile Concrete Plants
Concrete can be manufactured in a concrete batching plant temporarily installed on the construction site.
The mobile concrete plant allows concrete production on demand, depending on the progress of the site. This type of plant assumes sufficient space for its installation and raw materials’ storage (cement, sand, water).
Also, raw materials should be stored in a clean, dry place away from moisture. Indeed, materials such as water and additives should not come into contact with water. Mobile concrete plants bring together heavy installations capable of producing up to 35 m³ / hour.
Dry Mix Concrete Plants
The dry concrete batching plant uses digital or manual scales to weigh the various constituents of concrete. Subsequently, they are unloaded in a chute which flows into a truck.
During this time, the water is also volumetrically weighed or metered and discharged through the same loading chute in the mixer truck. All the materials are then mixed for at least 70 to 100 turns during transport to the job site.
Wet Mix Concrete Plants
The wet concrete batching plant puts some or all of the dry mix plant materials; they add water into a concrete mixer located at the center. The concrete will be unloaded into a mixer truck or agitator for transport to the construction site after mixing.
In short, the difference between the dry mixing installation and the wet mixing installation is that the wet installation includes a central mixer to produce a more stable mixture. The wet mix plant has deviations from breaks and variations from load to load.
With a central mixing installation, all loads have the same actions. There is an initial quality control point when unloading from the central mixer.

Very concretely, here are the various stages of concrete preparation in a Batch Plant:
Preparation and Transport of Aggregates
The aggregates are the first to be added to the mixer. They are therefore transported via a skip from their silo to a dosing tank.
At this point, the aggregates can also be sieved to retain only the finest. And yes: the grain size can be more or less important depending on the concrete. Some sites require fine gravel concrete for a more natural aesthetic appearance.
Once weighed and sieved, the aggregates are placed directly in the mixer or a waiting hopper.
Transfer of the Other Constituent Elements of the Concrete
The other elements of the mixture are transported from their tanks to waiting hoppers (using belts or pumps) or else poured directly into the mixer after the aggregates, in the following order: cement, water, then additives.
Thanks to the predefined programs, each component arrives in precise quantities. Mixing water comes from water treatment reserves, rivers, or lakes.
Like the other components of concrete, it is conveyed in extremely precise amounts. Concrete with too much water will lose its mechanical resistance.
Mixing the Concrete Constituents
The mixing of the concrete is done for a determined time, depending on the nature of the latter. Also, the mixing time depends on the amount of material to be produced.
Depending on the volume of the mixer, this time is more or less important. The average production rate is estimated at 60 m3/h for a 1000 l mixer.
Note: During the mixing process, no dust comes out thanks to the presence of sealed covers.
Loading Concrete for Transport
Once the concrete is manufactured, it’s poured into a concrete mixer, a mixer pump, or even a carpet truck -depending on the accessibility characteristics of the site.
Transportation and Delivery of Concrete
You must arrive at the site within the hour: this allows the concrete to maintain consistency and, therefore, optimum resistance. On the way, the concrete mixer kneads the mixture continuously so that it does not harden.
Return of the Concrete to the Plant
When returning to the plant, the so-called “return” concrete (residues present in the router) is eliminated while cleaning the concrete mixer in a plant’s dedicated area. The remaining water and concrete pass through several settling tanks until filtered water is obtained, then recycled.
