Description

Cement waste screening and recycling device Technical Field The application relates to the field of cement, in particular to a cement waste screening and recycling device. Background The screening and recycling of cement waste is a key link for realizing the recycling of resources in the building material industry, and particularly the efficient treatment demands for waste materials such as caking cement, mixed crushed soil, unqualified semi-finished products and the like generated in the production process are increasingly prominent. The traditional screening technology is widely applied to the classification of sand and building rubbish, but faces the characteristics of high viscosity, easy agglomeration of micro powder, easy hardening of crushed soil and the like of cement waste, and the problems of screen blockage, incomplete separation of fine particles, secondary pollution and the like of the traditional equipment are frequently caused. The method not only causes the loss of recyclable materials, but also increases the energy consumption and the environmental protection treatment cost due to low screening efficiency, and restricts the large-scale recycling process of cement waste. The current mainstream drum screening machine (such as a typical structure comprises a feeding device, a multi-stage screen and a discharging device) realizes particle size classification through a rotary screen, has the advantages of high separation precision and low investment cost, but has the obvious defects that in the screening process, the crushed soil is easy to solidify into blocks on the surface of the screen due to the action of humidity or viscosity to form agglomerates with particle sizes close to those of the construction waste, so that the agglomerates cannot pass through the screen holes of the corresponding level, and finally are mixed into the large-particle waste to be discharged. This phenomenon not only causes a reduction in the recovery rate of crushed soil, but also affects the recycling performance of the subsequent waste materials due to the mixed soil blocks.
