Vertical Roller Mill For Cement
Vertical mill is dependant on advanced home and abroad technology, complement numerous years of experience with the creation of grinding machine. The vertical grinding machine is an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together. Vertical mill is the ideal substitute from the traditional grinding mills like raymond mills, questionable suspension grinding mills, ball mills, etc. It’s the solution for fine grinding and classification of your wide array of materials including, although not limited by calcium carbonate, dolomite, talc, bentonite, barites, petroleum, coke, calcium oxide and gypsum.
Vertical roller mill found in cement grinding plant
Vertical roller mill for use in cement manufacture with the continual increasing demand for portland cement and constant pressure for reduced energy consumption, producers are exploring a multitude of cost-saving manufacturing options. One choices vertical roller mill technology for finish grinding.
Traditionally, plants used ball mills to grind clinker and gypsum into cement. The end result: almost all (60%) of finish grinding on earth is still performed using the ubiquitous ball mill. Ball mills are cylindrical steel shells with steel liners. These rotating drums contain grinding media that tumble in the cylinder. The grinding balls cascade and tumble on the clinker and gypsum to make cement. Just about all ball mills make use of a form of closed circuit grinding that returns material which is too coarse to the ball mill inlet while material fine enough to satisfy product requirements is collected. The separator or classifier determines which particles is going to be returned and which particles are sufficiently fine. With an effort to improve production, ball mill physical size has grown almost towards the physical limitation dictated by the gas velocities and accompanying pressures essential for the process. Ball mills is probably not one of the most efficient means of size reduction however their history of product consistency and their simplicity of operation are making them an historic plant favorite.
Cement vegetation is increasingly seeking to vertical roller mill technology for his or her finish grinding needs. Vertical roller mills present a compact and efficient grinding method. Clinker and gypsum is ground over a rotating table that passes under large rollers. Material is forced off of the table by centrifugal force, where it really is then embroiled into an airstream with a classifier immediately above. Just as with a ball mill, material that’s too coarse is returned for the table for more grinding while material that’s fine enough is collected as product. The compact design of a vertical roller mill allows it to dry, grind, and classify, all within one machine and all sorts of in a relatively compact space. Vertical roller mill technology allows: (1) power consumption savings; (2) consistent product quality and (3) process simplification.
