AI Technical Summary
In existing technologies, after wollastonite is crushed, some large pieces of raw material that do not meet the standards still enter subsequent processing, affecting production quality.
A screening and recycling mechanism for wollastonite crushing and processing was designed. Through the combination of a crushing box, a mounting box and a screening frame, the raw materials that do not meet the crushing standards are screened and recycled for reprocessing. The screening and rotation are achieved by the cooperation of components such as mounting shaft, gears and cylinders, ensuring that the raw materials that meet the standards are discharged, and the raw materials that do not meet the standards are crushed a second time.
This effectively prevents substandard raw materials from entering subsequent processing, improves the production quality of wollastonite, and ensures efficient screening and reprocessing of recycled materials during the crushing process.
