How to run sand production line better?

The sand making production line is a common production line in various stone factories. Its operation and operation are of great significance for the stone plant. The sand making machine is one of the important equipment in the sand production line, which needs correct operation and maintenance. For the sand production line put into operation, there are several suggestions, hoping to be helpful to stone producers.

Sand production line is a common production line in stone factory, and its finished products are also essential building materials for all walks of life. Sand and gravel are indispensable for urban construction, expressway, water conservancy and hydropower.

1. High quality products

After the sand production line is put into operation, the finished products need to reach high grade and good shape.

2. Low operating costs

That is to ensure low operating costs after commissioning, such as labor costs, shipping costs, etc.

3. High efficiency operation

In the sand production line equipment configuration, must be reasonable and effective, in order to ensure that after putting into operation, can run with high production efficiency.

4. Low construction investment

In the initial stage of production and construction, chemical analysis of raw materials and comprehensive test of metal abrasivity should be done well, and reasonable host equipment should be selected. At the same time, the process layout of the whole production line should be simple and smooth, and the one-time investment should be reduced as much as possible.

5. High resource utilization

Fully integrate cement plant and gravel line, and make all finished products play their respective roles as far as possible, that is to achieve zero emission and zero waste of resources.

6. Build a safe and reliable production line

Interlock control is carried out in single equipment room and automatic control is realized in the whole line, that is, on-line and off-line control of simultaneous operation beside and on the machine, so as to ensure the safe and reliable operation of the whole sand making production line.

7. Build into an intelligent production line integrating informatization and informatization

According to the grain size requirements of finished products, automatic adjustment of single machine operation conditions, online quality monitoring, remote control and ERP process management.

8. High standard environmental protection requirements of zero emission in the whole line

The whole plant needs to build a closed plant, all dust collection points for scientific dust collection, at the same time, combined with atomization spray, realize zero emission, at the same time, realize the mining and reclamation at the same time, and build the sand production line into a green, environmental protection and ecological modern industry.

Operation Guide for Sand Making Machine

At present, due to the increasing demand for sand and gravel in engineering projects, the supply of natural sand is difficult to meet the market demand. In this context, the artificial sand industry is gradually rising, which not only expands the use of mining machinery, but also accelerates the improvement of related technology and process technology. As an important part of sand and gravel production line, sand making machine plays an irreplaceable role in the whole machine-made sand production, so the stability and durability of its components are particularly important to the life of sand making machine and the investment of customers.

It is generally believed that impeller device, which plays a decisive role in sand making machine for material injection, is an important component of sand making machine, and its working stability determines the working efficiency of relevant conveyors, feeders and sorters.

The following aspects should be paid attention to:

1. Before start-up, the inspection door of whirling chamber should be closed tightly, mainly to prevent the material from rushing out of the observation door of whirlpool chamber and causing safety accidents.

2. Check the rotation direction of the impeller from the direction of the feed inlet. The impeller should rotate anticlockwise, otherwise the motor wiring should be adjusted. This is an area that needs special attention.

3. The start-up of the production line should also pay attention to a certain sequence. Generally, it is suggested that the starting sequence of sand making machine and conveying equipment is: discharging → sand making machine → feeding; the crusher must be started with no load, and feeding can be carried out after the crusher operates normally. The shutdown sequence is opposite to the start-up sequence.

4. The feeding particles shall be strictly in accordance with the specified requirements. It is forbidden to enter the crusher with materials larger than the specified ones. Otherwise, the imbalance of the impeller and excessive wear of the impeller will be caused, and the impeller channel and the central feeding pipe will be blocked, so that the crusher can not work normally. If large pieces of feed are found, they shall be discharged in time. There are also to prevent the non broken materials (such as metal) into the crusher.

5. When the discharging equipment stops, the feeding should be stopped in time, otherwise, the impeller will be crushed and the motor will be burned.

6. The lubrication of the machine is dry oil lubrication, and the amount added is 1 / 2-2 / 3 of the bearing cavity. When the crusher works every shift, add appropriate amount of grease. The maintenance and monitoring of bearing should be paid attention to when the running machine is overhauled.

7. In order to ensure the high energy-saving efficiency of the sand making machine, the tension force of the driving V-belt of the sand making machine should be adjusted appropriately to ensure the uniform force of the V-belt. When the belt is driven by two motors, the triangular belt on both sides should be selected in groups, so that the length of each group is as consistent as possible. When parking, pay attention to the wear of impeller and other parts, and replace the vulnerable parts in time.

In addition to the above, in the configuration process of the entire production line, the coordination of various equipment should be considered. In the selection of equipment, attention should be paid to combining with the actual situation, so as to maximize the potential of each equipment.

Installation requirements of impact crusher plate hammer

Impact crusher is an important crushing equipment, it has a strong crushing production capacity, has an extraordinary position in the field of crushing equipment. Plate hammer as an important part of impact crusher, its installation requirements are very high, let's take a look at the specific requirements.

1. High strength high manganese steel, high chromium cast iron, alloy steel, malleable cast iron or other wear-resistant materials are usually used in the plate hammer of impact crusher. High strength cast steel is widely used in China.

2. Besides the common strip shape, there are T-shaped, S-shaped, I-shaped, grooved and other shapes, and the strip shape is widely used.

3. The repair of plate hammer can be overlaid with wear-resistant materials in carbon steel plate and high manganese steel group.

4. The weight difference of each plate hammer of impact crusher should not exceed 50g, otherwise it will seriously affect the balance of the machine.

5. When replacing the plate hammer of the impact crusher, all the plate hammers must be removed for surface replacement to prevent the rotor from losing balance and the internal vibration of the crusher, resulting in production accidents.

6. The gap between the plate hammer and the grate plate should be consistent, and the error should not exceed two millimeters.

7. The impact crusher can't swing away during the operation due to the too tight plate hammer, which causes the vibration of the crusher.

8. The number of plate hammers is related to the size of the rotor. The larger the rotor size, the more plate hammers.

9. The fixing methods of the plate hammer on the rotor are as follows:

① The bolt is used to fix: the bolt directly on the plate hammer is easy to cause wear, and the screw is also easy to cause fracture.

② Press plate fixation: the plate hammer is usually inserted into the groove of the rotor from the side, and the two ends are pressed by the pressing plate, which is easy to loose.

③ Wedge fixation: wedge is used to fix the plate hammer on the rotor. Under the action of centrifugal force, it will be more tight and convenient to disassemble and replace.
