subject: Performance Characteristics Of The Spiral Washer [print this page] So far, the spiral washer and sand washeris widely used in the ultrafine classification process for a variety of materials, including the abrasives, calcite, talc, limestone, graphite, quartz, diatomaceous earth, chemical raw materials (toner, additives, phosphor, dyes, pigments, silica gel, etc), ceramic powder, pharmaceuticals, pesticides, glass powder, and so on. The performance characteristics of the spiral washer are as follows.
1. The motor of spiral washer adopts the straight-through connection. Compared to the connection way of belt driven, this way is more convenient in structure, lower in failure rate, and easier to maintain.
2. The entire classifying system uses the negative pressure to run, so there is no dust leakage happening in the working process of equipment. In addition, only a small vibration will produce when the device is running and the noise is low, so it will not cause the environmental pollution in the working process.
3. In the working process, the gas and the material move smoothly in the spiral washer. The air will enter the spiral washer along the tangential direction, forming vortex rotation movement. After the function of the guide vane in the deflector plate, the air in the spiral washer will be distributed smoothly and uniformly, creating a better particle separation and classification condition.
4. All the internal parts and components in the spiral washer, which will connect with the material, can be inset the wear resistant material with high strength, so that the abrasion loss will be reduced greatly. The routine examination only needs to pay attention to the internal wear-resistant material, checking whether there is a shedding on the material, and whether there is damage on the blade. In the daily use, it is necessary to add oil to the machine on time, preventing the air leaking from the hole on the body and preventing the debris falling from the feeding inlet.
5. High classifying efficiency. Because the air and the material mix uniformly and the air and material proportion is big, and the air is smooth, the separation of materials can be completed successfully in the spiral washer.
