Bauxite crushing: bauxite is the additive. For making cement raw materials, bauxite is crushed by cement equipment into powder. Then bauxite particles and limestone particles together are ground into raw powder by raw mill.
Gypsum crushing: gypsum powder made by gypsum crusher and gypsum mill are put into cement clinker together with coal powder, then these cement raw materials enter into the cement mill for fine grinding.
The dust catcher, also known as dust collector, is the most widely used powder separating equipment in the dry method cement production line. The dust collector implements winnowing to the powder with impellers driven by the motor. And the powder separating work can be done according to the requirements for granularity of customers. The rotation speed of impellers must be increased to add the contact area to achieve much finer particle size. Coarse powder will fall into the grinding chamber for regrinding. The powder meeting the standard will enter into the main cyclone collector.
