The coal screen has the advantages of small size, light weight, simple structure, convenient installation and maintenance, large handling capacity, good quality, low noise, low power consumption, strong adaptability to various materials, stable operation, etc. Now it has been widely used in mining, metallurgy, coal, building materials, light industry, chemical industry, electric power, grain and other industries to divide the massive, granular and powdery materials into uniform particles without agglomeration and good porosity.
The selection of the motor for the coal screen seens simple, but it is actually a profound knowledge. I hope that the technicians of those manufacturers who need this equipment can make a more profound study of it.
For oversize or undersize meshes, first select them for measurement and then select two representative sampling positions. Measure 10 consecutive mesh apertures, and then calculate the average value as the mesh: fL~L diameter. For screens with less than 20 meshes, all mesh diameters shall be calibrated
If the above points can be taken into account when calibrating the test screen, it will not only bring a lot of convenience to the calibration work, but also prevent enterprises from unsatisfied screening accuracy, unsatisfactory screening output, inconvenient operation of screening equipment, too much trouble in replacing the screen and too short life of the screen when using the screen. It can also meet customer requirements. It can not only help them to strictly control the quality, but also really care for customers, In addition, it can also improve the calibration efficiency and the accuracy of screen aperture and wire diameter measurement results.
Therefore, the rotating speed of conventional coal block vibrating screen is about 15 revolutions per minute, and that of smaller coal block vibrating screen is about 20-25 revolutions per minute. This is the angle analysis result of the manufacturer of coal vibrating screen. I hope it will be helpful to everyone. In addition, please pay attention to the maintenance of the coal block roller screen after use. In this way, no matter the productivity is improved, or the failure rate is reduced, or the service life is increased, there are great benefits.
Working principle and structural characteristics of coal dewatering screen
The screen adopts a flange type vibration exciter, which is externally pulled by two motors for reverse self synchronous rotation, making the screen body periodically reciprocating along a straight line, so as to achieve the purpose of water separation. The screen frame of Longzhong dehydration screen is connected by G-strength bolts. The screen surface is composed of arc section and straight section, and the structure is firm and durable.
- Dehydration screen structure, small size, light weight, efficiency G, low noise, using a new type of vibration motor for direct drive.
- The dehydration screen has simple structure and convenient maintenance.
- The beam of dehydration screen is connected to the screen box with G-strength bolts, without welding.
- Polyurethane screen is used for screen, with screening efficiency of G, large processing capacity and long service life.
- Through years of production practice, it has been proved that this series of dewatering screen has a series of * points, such as large handling capacity, reasonable technical parameters, structural strength G, serialization, generalization and standardization degree G, and convenient maintenance and repair.
