Refractory raw materials processing is to enter the factory of various shapes and sizes of refractory raw materials (including raw ore and clinker) into the required size, and remove impurities mixed with refractory raw materials for the preparation of brick use. Refractory raw material processing include: selection of refractory raw materials, crushing, grinding, fine grinding and screening.
The selection of raw materials into the plant
The selection of refractory raw materials into the plant there are two main purposes: (1) selected mixed in the raw materials in the debris, under burning material, not burning fuel and tumor blocks, etc .; (2) According to the appearance of refractory raw materials Features are stacked for ease of management and use.
Broken smashing purposes
The mechanical method (or other methods) exerting external force on the large refractory raw materials so as to fragment them into small pieces or fine powders is called raw material crushing and pulverizing.
Usually two or three broken crushed. That broken – broken pieces of material from 250-300mm broken 40-50mm;
Crush – Material block size from 40-50mm crushed to 4-5mm;
Fine grinding – finely ground material size from 4-5mm to less than 0.088mm.
The purpose of crushing is to prepare massive refractory raw materials into pellets and fine powders with a certain granular composition so that powders of different compositions are prepared and mixed uniformly; the specific surface area of ​​the raw materials is increased and the physicochemical reaction speed is increased.
