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.

What Are the Different Types of Concrete Batching Plants? |

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.
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.

How Preparation of Concrete Is Done in Batch Plant |

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.

Why Use a Concrete Batch Plant? |

There are many advantages to using a concrete plant.
First of all, it allows you to save considerable time on completing your site: no need to carry out your concrete yourself!
The concrete produced in the plant is quality certified (dosage, storage of elements in suitable dry places, additives in precise quantities, etc.). Therefore, it is the assurance of solid slabs that do not sag or crack over time, unlike the risks presented by those from handcrafted manufacture.
Also, the concrete batching plant allows you to transport a large quantity of concrete to the site.
For small volumes, delivery by a concrete mixer from 1 m³ is entirely possible. An additional price may nevertheless be requested due to the displacement of the almost empty router. This one can generally contain 7 to 8 m³ of concrete.
Using a concrete batching plant, you, therefore, ensure unparalleled durability of your concrete structure while saving time on its completion.
The concrete batching plant has automated operations. A control cabinet allows the following steps to be carried out:
Weighing control
Transport of materials
Measurement of the humidity of the concrete
Level of fluidity
Mixing
For each type of concrete, a formula is pre-established, and a program is associated. The professional, therefore, only needs to launch the program corresponding to the customer’s order: type of concrete chosen and quantity

What Are the Components of a Concrete Batching Plant? |

A traditional concrete batching plant mainly consists of:
Cement silo. Equipped with a filter to ensure the best possible quality
Aggregate silo. Sand and gravel are transported by truck, train, or boat from the quarries. On arrival, they pass through a hopper before being transported via conveyor belt to this storage silo.
Dosing tank
Adjuvant tanks. Each contains a different adjuvant: setting accelerator, retarder, and plasticizer.
Weighing system
Water supply equipment. Consist of a tank and a pump for the transfer of liquids.
Concrete mixer
Each concrete batching plant component has safety systems preventing any leakage or pollution, whether terrestrial or atmospheric. The cement silo has a dust filter to prevent release into the atmosphere. As for the adjuvant tanks, they are raised and installed themselves in sealed compartments and certified frost-free.
The aggregates (sand, gravel, etc.) are first transported to the dosing tank using a silo or a skip (feed bucket mounted on a lifting and tilting system). Then they are weighed by a weighing belt and transported by the conveyor belt to the mixer (or the concrete mixer).
The mixture’s various elements are then introduced into the mixer: cement, water, and any additives.
The quantities of material and the mixing times depend on the type of concrete produced and its constituents’ characteristics. Once the operation is complete, the mixture is loaded into a mixer truck or transported by concrete mat to the site.
In general, the control unit is operated from a control cabinet, mainly allowing:
the control of material weighing systems
measuring the humidity of the aggregates using hygrometry detectors
the water supply dosage according to the desired level of fluidity
Note: Some models incorporate a vertical aggregate silo, with the advantage of reducing the plant’s size and the sound volume produced by the flow of materials.
Also, more and more mixers are equipped with sealed covers which prevent dust from escaping during mixing. This has the double advantage of improving the quality of the concrete produced and better protecting the environment.

Before we understand the working or operation of a concrete batch plant.It is important to understand the basic components and structure of a batching plant. We have mobile concrete plants installations in Philippines’s city like: Bulacan, Cavite and Pampanga. It is a machine that combines various ingredients like aggregates, sand, water, cement and additives.These components are first weighed individually and then combined to prepared ready mix concrete. This material prepared is widely used for several types of construction projects.
Since the mixing of individual components is by weight it is possible to alter and change weight of individual materials to prepare different grade or quality of concrete. Some of the grades of concrete for India are as 1:3:6, 1:2:4, 1:1:2 etc. Here we express the proportions of the ingredients of the concrete mix in terms of ratios or parts of cement, fine and coarse aggregates. When we talk about 1:3:6, it defines the ratio or parts of cement, fine and coarse aggregates. Meaning the mix material has one part of cement, three parts of fines and six parts of coarse aggregates. The proportion is by weight.
concrete batching plant is divided into four parts: gravel feed, powder (cement, fly ash, bulking agents, etc.) to feed, water and feed additives, transmission and storage stirred their workflow shown in Figure 1. , the mixer control system power, into the human – machine dialogue operation interface, system initialization process, including recipe number, grade concrete slump, producers, etc. according to the amount of weight carried on each silo, weighing hoppers. detection, output material or material empty full signal, prompting the operator to determine whether to activate the control program starts stirring sand, stone belt motor fed into the metering hopper; open fly ash, cement tank valve, start the electromechanical screw conveyor ash cement to the metering hopper; open water reservoir and control valves admixture pool water and additives into the metering hopper metered meet the set requirements doo door open metering, mixing the ingredients into the mixer within already started to set. time to open the mixer door, into the concrete mixer had received material.

Hydraulic excavator with powerful digging feature
Modern hydraulic excavators come with a powerful digging mode. The latest setting delivers the power and response you need for general operation, from excavation to loading and lifting. The large excavator’s digging performance can be further enhanced with different power modes. One of the key benefits of a hydraulic excavator is the ability to achieve motion via hydraulic actuators such as cylinders and swing motors. And when hydraulics are combined with modern technology such as grade control, laser positioning, and GPS, the potential seems almost endless. The vast majority of equipment found on construction sites across the world is propelled by hydraulic power. That includes hydraulic final drive motors that convert hydraulic power to torque to enable track loaders, bulldozers, diggers, and backhoes to carry or push heavy loads. These motors, which are sometimes referred to as track motors, enable tracked excavators, bulldozers, and other tracked machines to keep moving across some of the most difficult surfaces imaginable.
Manufacturers are also incorporating more sophisticated hydraulic functions that allow the operator to adjust hydraulic flow to the application. Hydraulic upgrades on the latest models include selectable modes to optimize available hydraulic speed and power, plus a manual throttle dial to adjust engine speed and power as needed. Hydraulic efficiency has been a big concentration point for manufacturers.
