Technical Field
[0001] This utility model relates to the field of polymer grinding wheel powder technology, and in particular to a continuous vibrating sieving pretreatment device for polymer grinding wheel powder. Background Technology
[0002] Polymer abrasive grinding wheel powder is a grinding material powder made by mixing polymers (such as resins, ceramics, etc.) with abrasives (such as diamond, silicon carbide, corundum, etc.) and auxiliary components (fillers, pores, etc.) as a binder. The production of polymer abrasive grinding wheel powder requires screening through a screening device.
[0003] However, in existing equipment, polymer grinding wheel powder is usually continuously fed into the screening box for vibratory screening. However, continuous feeding is prone to uneven screening due to flow fluctuations, which affects the screening quality. Therefore, a continuous vibratory screening pretreatment device for polymer grinding wheel powder is proposed. Utility Model Content
