Six professional skills to reduce screw conveyor loss
Release date: 2019-04-22 Article source: Zhengzhou Changli Construction Machinery
During the operation of the screw conveyor, the loss during the operation of the machine is quite large, so during the work, several key technical points that need to be understood are quite practical. The key technical points to reduce the loss of the screw conveyor are as follows:
1. Reduce the granularity of the ground materials: After reducing the granularity of the ground materials, the average size of the grinding body and the filling rate in the mill can be appropriately reduced, which is of great benefit to the protective liner. From the perspective of energy saving and consumption reduction, the more material a pair of liners grinds during its service life, the lower its abrasion cost. Production practice proves that the material must be pre-treated before entering the mill to reduce the particle size to less than 4-6 mm, the mill production efficiency can be increased by 30% -50%, and power consumption can be reduced by 10% -20%. The reduction of the abrasive grain size has a certain effect on reducing the wear of the liner.
2. Adopting closed-circuit grinding technology: Using closed-circuit grinding technology and using higher education powder selection equipment, it can increase output by 30% -40% on the original basis and reduce grinding power consumption by 3-5 kWh / ton. At the same time, due to the "buffer pad" effect of the recycled material, the wear of the liner is effectively reduced.
3. Strictly control the moisture content of the milled material: when the comprehensive moisture content of mill A material is greater than 2. At o%, not only the powder efficiency is reduced, but also the service time of the liner is shortened due to the corrosive wear. Therefore, it is necessary to strictly control the moisture content of the incoming materials to reduce the wear of the liner.
4. Reduce the grinding temperature: cold material feeding, simplified water spraying, and water spraying inside the mill are usually used. The latter has a significant cooling effect.
5. Adopt the fine grinding silo liner activation technology: the arrangement of the fine grinding silo village plate significantly affects the production efficiency of the mill. The combination of the new and old liner arrangement to achieve the activation month can not only improve the dropping height of the grinding body and The number of throws ensures the fineness rate of the finished product, and can reduce the wear of the liner and increase its service life.
6. Using rod grinding technology: The grinding body used by the rod mill is a steel rod, which has a good "line" contact state with the material being ground. The rod load has the special function of "selective" crushing to the physical science. During the grinding process, Grinding, pressing, rolling, rolling and grinding forces are generated, so the grinding efficiency is high.
Questions and answers about concrete machinery and equipment
Q: How long is the 120 station belt conveyor suitable?
Answer: The total length of the horizontal conveyor belt used in the HZS120 concrete mixing station is about 50 meters.
Q: What is the discharge height of 25 concrete stations? Is it completely unified?
A: The discharge height of the mixing station is generally 3.8 meters, but with the change of the concrete transport truck, it is now adjusted to 4.1 meters.
Question: HZS120 concrete mixing station, I saw a bucket-type belt.
A: Many sites receive customers with strict restrictions. The HZS120 station can also use a bucket belt conveyor.
Q: How much is a small concrete mixer?
Answer: The reason why it is called a small concrete mixer is that because of its small volume, the mixing volume is small, so the quality of the whole machine is not high, mostly one to two tons.
Q: How much does a computer control system for a HZS120 mixing station cost?
Answer: According to the configuration specifications of the electronic control system, the selection of components is different. There is a certain difference. The price is a reasonable price between 80,000 and 100,000.
Q: The price of PLD1600 batching machine four warehouses? How much does it cost?
Answer: This type of batching machine is commonly used in large concrete mixing stations. It is a necessary supporting equipment of the mixing station. Generally speaking, it will not be used alone. In terms of price, different manufacturers have large price differences. For details, please contact professional manufacturers, such as Zhengzhou Erba Machinery Factory, Zoomlion, Zhengzhou Changli, Changli Construction Machinery, etc.
Question: How high is the height required for the HZS180 mixing station to transport concrete with a transport truck?
Answer: At present, the discharging height of HZS180 stations of domestic large-scale manufacturers is mostly designed to be 4.1 meters, which is convenient for various types of concrete transport vehicles to enter and discharge.
Q: Which brand of JS1000 concrete mixer is better? Which manufacturers are more powerful?
Answer: There are many domestic manufacturers of JS1000 concrete mixers, and professional and powerful manufacturers, such as Zhengzhou Erba Group, Zhengzhou Changli, Changli Construction Machinery, Zhengzhou Innovation, Shandongfangyuan Group, etc.
Q: How high is the discharge height of the HZS120 mixing station?
Answer: At present, the discharge height of HZS120 stations of domestic large-scale manufacturers is mostly designed to be 4.1 meters, which is convenient for various types of concrete transport vehicles to enter and exit.
