Cement clinker ball mill is a new energy-saving grinding equipment designed by domestic processing machinery experts after absorbing the newest grinding technology home and abroad. It performs an excellent job in secondary crushing, finely crushing and super finely crushing, from limestone to basalt, from stone production to various ores crushing.
It is now a new-generation product in mining construction that can replace spring cone crusher and update general hydraulic cone crusher and an ideal equipment for large-scale stone and mining crushing, having the features of low investment, energy saving, simple structure, easy operation, safety use, reliability, etc and applicable to grinding and mixing general and special materials. Customers can choose suitable model, lining board and medium type according to material proportion, hardness, output as well as other factors.
cement vertical roller mill for sale
In recent years, cement clinker plants are increasingly looking to vertical roller mill technology for their finish grinding needs. Vertical roller mills present a compact and efficient grinding method. Clinker and gypsum is ground on a rotating table that passes under large rollers.
Material is forced off the table by centrifugal force, where it is then swept up into an air stream to a classifier immediately above. Just as with a ball mill, material that is too coarse is returned to the table for additional grinding while material that is fine enough is collected as product. The compact design of a vertical roller mill allows it to dry, grind, and classify, all within one piece of equipment and all in a relatively compact space.
Vertical roller mill technology allows: (1) power consumption savings; (2) consistent product quality and (3) process simplification.
Cement production process
grinding limestone (and other raw materials to achieve the right chemical composition) to about 90% passing 90 microns in a dry circuit.
making cement by the chemical reaction between the components of the ground mixture. This chemical reaction occurs at high temperature in a rotary kiln.
grinding the cement clinker nodules to 100% passing 90 microns in a dry circuit.
