Description

Special milling equipment of plastics preparation Technical Field The utility model relates to the technical field of plastic processing equipment, in particular to a special grinding device for plastic preparation. Background In the plastic processing industry, the grinding link plays a key role in the subsequent treatment of plastic raw materials and the final quality of products, and in the operation process of a traditional plastic grinding device, an abrasive disc is used as a core grinding part, so that high-strength grinding operation is required to be continuously carried out on the plastic raw materials. However, since the plastic powder itself has the characteristics of easy adhesion and easy accumulation, a large amount of plastic powder inevitably adheres to the surface of the abrasive disc and the abrasive holes in the grinding process, and as the grinding work continues, the adhered powder gradually accumulates, so that the effective working area of the abrasive disc and the abrasive holes is continuously reduced, which not only can lead to insufficient contact between the plastic raw material and the abrasive structure, influence the grinding effect and reduce the grinding efficiency, but also can lead to uneven granularity of the ground plastic powder, overlarge or undersize partial powder particles, and difficult to meet the strict requirement of the subsequent production on the granularity of the plastic powder, thereby seriously affecting the overall quality of the plastic product.
