Concrete batching plants divides into different types according to different classification criteria. The following is a brief introduction to the different types of batch plants.
Concrete batching plants, generally, are divided into stationary concrete plants and mobile concrete plants. This is a basic classification that many manufacturers distinguish at the time of production. Most of the stationary batching plants adopt the modular and splicing design, which is mainly used for large-scale commercial concrete manufacturers or related manufacturers of concrete components. It usually applies in large-scale engineering construction, owning the features of strong production capacity and stable anti-interference. The mobile batching plant is towed by a towing unit, which has good maneuverability and makes the production more flexible. It generally uses for various small and medium-sized temporary construction projects. Besides, it can be rented for personal use.
According to the application, the concrete batching plant is divided into commercial concrete plant and engineering concrete plant. The commercial concrete plant is a concrete mixing station based on commercial purposes. It should be efficient and economical, meeting environmental protection standards. The engineering concrete plant is often for self-use. The buyer should have a consideration that whether it is in accordance with the engineering.
According to the number of concrete mixers, the concrete batching plant divides into a single host batching plant and double host batching plant. The model name of the double main mixing station is the "Double HZS" series concrete batching plant. For example, Double HZS25 concrete batching plant means that this batching plant equips with two JS500 concrete mixers.
According to the weighing method, it divides into independent weighing and cumulative weighing methods. On the one hand, independent weighing equips with a separate weighing unit for each material. After weighing each material, these materials will be mixed in the mixer. This weighing method has high precision, but it has a complicated design and cost. On the other hand, the accumulated weighing is to add all the aggregates into the unified hopper. It is prone to errors and unfavorable for the final production, and the more the number of batching bins. Besides, The more batching bins, the more likely the deviation will occur. So this method is not suitable for large projects. It, however, has a simple structural design and low cost.

In the operation of the mixing plant, the mixer makes all kinds of raw materials for making concrete products mixed and broken, and then through a variety of processing, which has become a different type of concrete products. It can be said that the mixer has a pivotal role in the mixing plant equipment. Today let me introduce you to the concrete mixing plant dedicated single and double shaft mixer difference.
1.The mixing shaft of the transmission system: single-axis mixing of the main drive system is the chain drive structure, while dual-axis mixing of the main drive system is the V-belt and slip gear structure. Comparing with the single-axis mixer, the process of generating noise is relatively low of dual-axis mixer. Moreover, its design has overload protection, which is relatively safe and convenient. In general, the large concrete mixing plant is used more.
2.The difference of the mixing effect: the agitation effect of single-axis mixing of the main drive is different for different types of concrete. In the production of common types of concrete, its mixing effect and the dual-axis mixer are comparable. But if producing some high demand for concrete products such as Rolling concrete, the mixing effect of single-axis mixer is relatively poor. However, The overall mixing effect of the biaxial mixer is better than the single axis mixer, and the degree of wear is extremely low.
3.The difference of the discharge performance: single-shaft mixer unloading mouth size is relatively tight, which is difficult to adjust in the actual production. Furthermore, its discharge gate is very stuck, and the discharge performance is quite ordinary. While the biaxial mixing host is effective to solve this problem, and the discharge performance is relatively excellent. This is another so essential reason that commodity concrete mixing plant is now used in the dual -axis mixer.

Among them, the mobile sand making machine is a new type of sand making equipment developed on the basis of a fixed sand making machine. The main machine configuration is still impact crusher, but the sand making machine and vibrating screen are fixed on the vehicle-mounted system, and the whole body can move freely, no fixed installation, easy to change the production site at any time.
The host of the mobile sand making machine is the impact crusher. At present, Liming Heavy Industry produces VSI, VSI5X, and VSI6X series, which have a wide application foundation and good reputation in the field of machine-made sand. Later, mobile sand making machines and VU system sand making will be launched. It is also based on the good effect of impact crusher and sand making.
Different forms of sand making require different equipment, and their prices are very different. Therefore, the price of 80T/hour large-scale mobile dry sand making machine depends on the specific equipment configuration. You can leave detailed needs such as raw materials, capacity, feed size, output size to online customer service, and we will arrange technicians to make selection plans and quotation budgets for reference.

The jaw crusher is a machine widely used in the mining and building materials industries. Why does the jaw crusher lining fall off during the production process?
1. Analysis of the reasons for the jaw crusher lining falling off
1. The lining material is not suitable
Some linings produced with low-quality materials are prone to breakage and wear during use, resulting in falling off. Therefore, when purchasing a jaw crusher, it is necessary to choose high-quality, sturdy and durable linings to ensure its stability and safety.
2. The lining is not installed in place
If the lining is not properly installed in place or is not properly locked on the machine, vibration and deformation will occur during the operation of the machine, resulting in the lining falling off.
3. Wear of running parts and lining
After a long time of use or excessive pressure during the production process, wear will occur between the running parts of the machine and the lining, resulting in the lining falling off.
2. Solutions to the lining falling off of the jaw crusher
1. Choose a good lining
When purchasing or replacing the lining, choose a lining with good quality and stable quality to ensure the quality and safety of the lining.
2. Correct installation of the lining
Correct installation of the lining is one of the important factors to ensure the use of the jaw crusher. When installing the lining, it needs to be firmly fixed to avoid loosening during use.
3. Regular maintenance and replacement of operating parts
In order to avoid unnecessary wear and tear on the operating parts and linings, the jaw crusher needs to be regularly maintained and the worn parts replaced in time. This not only ensures the safety and stability of the machine, but also extends the service life of the machine.

| What to do if the tooth plate of the jaw crusher is worn |
|
Posted by: slopoutor - 06-14-2024, 09:21 AM - Forum: Earth moving machinery

When the tooth plate of the jaw crusher is worn, the following measures can be taken:
1. Repair the wear in time:
For the worn tooth plate, it can be repaired by surfacing to extend its service life. When repairing, arc welding or automatic submerged arc surfacing can be selected.
During the repair process, it should be ensured that the surfacing tooth shape can be restored to restore the normal function of the tooth plate.
2. Choose suitable repair materials:
Select repair materials that match the original material of the tooth plate to ensure that the repaired tooth plate has sufficient hardness and toughness.
If the tooth plate is made of high manganese steel, similar materials should also be selected during repair.
3. Pay attention to tightening the jaw plate:
After installing or repairing the tooth plate, pay attention to tightening the jaw plate and ensure that it is in smooth contact with the surface of the machine body (dynamic and static jaws).
A layer of lead plate, plywood, cement mortar and other materials with good plasticity can be placed between the two surfaces to ensure the flatness and stability of the contact surface.
4. Adjust equipment parameters:
According to the properties of the material, adjust the main parameters of the crusher, such as the jaw angle, eccentric shaft speed, output and motor power, so as to adapt to the material entering the crusher and reduce the wear of the tooth plate.
5. Control the nature of the feed:
Ensure that the material entering the jaw crusher meets the specified particle size range to avoid excessive wear of the tooth plate by materials that are too large or too small.
At the same time, prevent iron blocks or other impurities from entering the machine to avoid serious wear of the tooth plate.
6. Select high wear-resistant materials:
When replacing the tooth plate, choose materials with high hardness and good toughness to manufacture the tooth plate to reduce the wear of the tooth plate caused by chiseling and impact. Commonly used high wear-resistant materials include high manganese steel containing 12% to 14% manganese.
7. Improve the equipment structure:
Change the thrust plate to an upward inclined type so that the tooth plate has a downward component in the direction of movement of the crushing stroke, which is conducive to crushing the material and promoting the downward movement of the material. This can reduce the relative sliding between the material and the tooth plate, thereby reducing the wear of the tooth plate.
8. Prohibit long-term overload operation of the equipment:
Long-term overload operation of the equipment will cause cracks at the root of the tooth plate, resulting in failure of the tooth plate. Therefore, during the operation of the equipment, attention should be paid to the combination of work and rest to avoid long-term overload operation.

Concrete mixing stations are currently widely used mechanical equipment. Many people are hesitating between mobile and fixed types. CinaCharm will analyze the usage scenarios of the two models for everyone.
According to the differences in their structures, CinaCharm concrete mixing plants can be divided into movable mixing plants and fixed mixing plants.
The movable mixing station has good maneuverability and is suitable for small and medium-sized temporary building construction sites. The fixed mixing station has good stability and can be suitable for medium and large commercial concrete manufacturers.
According to the difference in operation mode, CinaCharm concrete mixing plant can be divided into intermittent type and periodic type.
The intermittent feeding and discharging system is based on cycles. After the materials are weighed, stirred, and discharged, they will enter the next cycle. This method is more controllable and widely used. The continuous feeding and discharging is a complete flow operation and does not affect the overall construction period.
According to the difference in its technical placement form, CinaCharm concrete batching plant can be divided into single-stage type and double-stage type.
The single-stage type is to lift sand, aggregate, cement and other materials to the silo on the roof of the mixing station. Various materials are weighed, batched, and mixed according to the technical process until they are made into concrete mixers, which are discharged from the bottom. Loading and transportation. The single-stage technical process is complete and the productivity is high. However, due to the large investment in the single-stage type, generally speaking, the requirements for the factory are higher. The two-stage type is to first lift the required materials such as sand, gravel, aggregate, cement, etc. to the storage silo, and then lift or transport them to the mixer for mixing after being weighed in the storage silo. The materials need to be lifted twice during the whole process, which results in low productivity.
However, it is easy to disassemble and assemble and can reduce investment. This method is commonly used in general concrete mixing plants.
Both models have their own advantages and disadvantages. You need to choose the suitable type according to the factory's conditions. If you have any questions or needs, please feel free to consult CinaCharm.

The prime goal of piling winches is to left the hammer and piles in addition to support tools that responsible for leader raking and rotation. It functions with pile frames and different powering sources such as hydraulic power, stream; diesel; or petrol engines, and occasionally electric motors could be applied for powering winches. There are different piling winches with different capacity for instance winches with double or triple drums possess satisfactory controlling and pile driving speed whereas one drum winch does not have that advantage. So, the former type would be favored provided that handing and driving piles with great speed is required.
