Preparation of ceramic proppants

Ceramic proppant manufacturers man-made ceramic proppant traditional method of preparation agents mainly bauxite and fluxing phase (such as manganese ore) with a certain proportion, crushed grinding (particle size of 300 mesh), the disc granulator granulation step was prepared by raw material ball, high temperature sintering of medium or high density ceramic proppant. Through the oil shale residue, bauxite and fluxes in proportion with, crushed by disc granulator granulation was prepared by primer raw material ball, and then after high temperature sintering a low density ceramic proppant. China proppant oil shale residue is waste oil shale oil shale refining later.

Cumulative oil shale residue accumulation would take a lot of land, but also endanger the health of residents; the pollution of heavy metals in the process is a lot of oil shale residue contains, after rain leaching or diffusion of serious pollution to the surrounding water, land, poisoning of land, acidification, the destruction of soil productivity, disruption of agricultural production, to the detriment of health of the residents. But oil shale residue contains large amounts of mineral components, such as quartz, feldspar, clay and other ingredients, after firing the distillation, the structure is very loose, very light density, the larger the loss on ignition. Man-made ceramic proppant prepared and coated ceramic proppant use oil shale residue, not only can reduce the accumulation of oil shale residue on a lot of land occupation, to eliminate a serious threat to the environment, ecology and human health, but also can improve oil use value shale slag.
