After installing the concrete brick machine, the machine must be debugged:
1. Adjust the gap between the scraper of the feeding mechanism and the bottom plate of the barrel, which should not be greater than 2mm.
2. Adjust the gap between the bottom surface of the lower barrel of the feeding mechanism and the large plate to be no more than 0.5mm.
3. Adjust the gap between the adjustment ring of the upper barrel of the feeding mechanism and the feeding plate to be 0.5-1mm.
4. Adjust the track height so that after the brick is ejected, the mold surface should be 1mm higher than the plate surface (thin iron sheet is allowed to be adjusted on the track and the bracket surface).
5. Adjust the eccentric shaft of the brick pressing mechanism so that it can press out the required bricks.

Stone crushing machinery is an indispensable equipment for crushing plant. If you want to invest a sand and gravel processing plant, the purchase of crushing machinery is a more important process. It requires the investment budget for the production of machinery, and the equipment and manufacturers should be reasonably selected; Next, let's take a look at the more common types of stone crusher equipment.
1. The purchase of stone crushing equipment is not as simple as imagined:
The reason why stone crushing machinery is not as simple as you think is its diverse designs. According to different production requirements and processing materials, stone crushing equipment can be roughly divided into the following categories.
(1) High-hard ore crusher-jaw crusher, rotary crusher
Jaw crusher, as a well-known primary crusher, can coarsely crush materials of various hardness, and can select series for medium and fine crushing. In addition, the affordable price of the equipment, it can be said to be very cost-effective equipment.
The rotary crusher mainly adopts the principle of squeezing combined crushing, with low powder rate, and can be used for special crushing of high-hard materials. It is more economical and durable with iron-passing protection function.
(2) Medium hardness ore crusher-impact crusher, cone crusher, fine crusher
The four types of equipment selected above all use the "hit type" crushing processing principle, which is more friendly to the processing of medium-hard materials, but can also process high-hard materials.
(1) The impact crusher is a standard second-crushing processing equipment. It is characterized by no cracks and uniform quality, cubic shape and good grain shape.
(2) The impact crusher can also crush sand and is characterized by high sand rate, low water content requirements of processed materials, and favorable prices.
(3) Cone crusher can crush materials into shape at one time, with large crushing ratio, saving equipment investment and economic operation.
Stone crusher is a kind of crushing processing equipment, which can control materials for sand making processing according to customer needs, with high production efficiency and strong equipment rigidity.
2. How much is the price of stone crusher equipment?
The above has carried out a general classification and introduction to the crushing machinery, but each has its own unique processing characteristics and different areas of expertise. Because the manufacturing costs and labor costs of each equipment are different, the corresponding prices are also different; in addition, because the manufacturers have different estimates for the same equipment, the price of the stone crushing machinery is not fixed.

| What is the difference between a shovel and a backhoe loader? |
|
Posted by: slopoutor - 07-19-2024, 01:12 AM - Forum: Backhoe
- No Replies

Dynamics
The advantage of a backhoe machine is that they pull material towards them and lift with the minimum radius so the lowest power and forces are needed. With a front shovel the opposite is true - they lift at the maximum radius. Not only is the energy use of a backactor lower but it also places less stress on the structure of the machine.
However, Hyundai product engineer Joachim Van de Perre said, "With front shovels, while you have to be sure there is nothing unexpected in the loading pile as the operator does not have a clear view, the flow of hydraulic forces is more fluid in a front shovel as the force can be applied directly to the bucket. Also the kinematics are simpler with a front shovel as the bucket cannot go lower than the machine.
"Front shovels work by pushing into the pile, away from the machine, but a backhoe pulls the material towards the superstructure and also exposes the bucket cylinder to damage. The breakout forces delivered by a front shovel are generally larger, which means it can operate with a larger bucket, offering higher production." Volvo Construction Equipment excavator product specialist Rob Sinclair said, "The backhoe operator has a better vantage point when loading trucks and can dump the material in a more controlled manner, thus reducing truck wear. If the backhoe is worked correctly, it will typically slew through 45 degrees (or even less) and the face shovel 90. As a result, the backhoe usually proves more productive and invariably uses less fuel, while some would argue that slew wear is also reduced.
"Additional benefits include a better ability to load crushers; use a 'spike' to free lodged material from hoppers; work with a ripper to reduce, or eliminate blasting; more effective use of a hammer to reduce over-sized material."
Geology
Edwards added, "The geology of the quarry also has an influence on the advantages. When you blast, only around 15-20% of quarries will have a clean floor and in sites where the geology does not allow for this, the resulting toes will mean that the front loading shovel will only have a few points of contact on the tracks creating high stress. But a backacting machine sits on the blast pile giving it many more points of contact." Sinclair added that higher benches suit the face shovel but sites can usually be adapted to accommodate backhoe excavators if a different means of working the site is considered advantageous.
"The message that we are getting from quarry customers is that front shovels are slower," Case product portfolio manager for excavators Thomas Elberskirch. "The main benefit of a front shovel is its ability to work in a confined space, which may be useful in some parts of a quarry. A backhoe machine needs a platform to work from, which requires more room." According to Van de Perre, the quarry floor operation of a front shovel is safer as there is less risk of tipping over or instability.
Size matters
"The size of excavator can be directly related to the output of a quarry," said Edwards "Quarries producing 500,000tonnes of aggregates a year would generally have a 52tonne machine, while one producing 750,000tonnes would need a 60 to 70tonne excavator and quarries with a million tonne output are likely to need an 80tonnes machine.
"But that is changing with the trend towards contractor loading and hauling. Many quarries are looking to operate for three months to produce enough aggregates for the full year using contractors. As a result the contractors are using 'over-sized' machines for the output of the quarry to meet this demand. This trend is stimulating demand for larger excavators.
"The disadvantage is that the quarries find it difficult to meet specialist orders but it is becoming more common in Western Europe." According to Elberskirche, one thing the customer is asking for more is a better fitting product. "We have expanded our range to meet this demand," he said.
"In Central and Southern Europe there is a trend for using 60-70tonne excavators and maybe a 45 to 50tonne machine for sorting, but in Germany they prefer smaller machines - in the 35 to 50tonne range. To meet this need we recently added a special mass excavation model in the 47tonne class."
Future power
"We are always looking for ways to further reduce the cost of ownership and one of the most recent developments to come out of this has been the regeneration of hydraulic energy to create faster cycle times with lower fuel costs," said Edwards.
"On a 90tonne machine, the older version used to use 75 to 80litres per hour but the newer one with regeneration, requires 65litres per hour. Customers have said that the savings go a long way to paying for the operator and some of the finance. But fuel consumption needs to be considered in terms of the fuel burn to tonne moved." Fuel costs are being brought sharply into focus with closer attention on operating costs and with the advent of Stage IIIB engine emissions regulations due in 2011.
"The next stage will bring new fuel requirements, as well as less fuel efficiency from having to run hotter to burn off the emissions, and maintenance costs will be higher with extra filtration," said Edwards. "The engines are likely to be very sensitive." Elberskirch added, "More technology is needed to meet the new regulations and everyone is taking a different approach but the diesel engine is still the preferred power unit.
"Hybrid power on quarry sized machines could happen but not yet. Battery technology is the main issue but the higher price - of around 30% for hybrid machines - is also a problem for customers.
"The technology works but more sophisticated batteries are needed for larger machines. But quarry machines will never become fully battery powered as some cars are because of the changes on the load of the engine required by different parts of the cycle."
