Calcite fineness & application & sbm
SBM calcite grinding plant can pulverize calcite materials into the following finesse to satisfy different applications. No matter calcite powder is needed as raw materials for paper making, or paint & coating production, the SBM customized grinding plant can reach your requirement.

Calcite grinding mills
SBM Machinery （grinding mill） can supply the state-of-the-art manufacturing facility which is fitted for calcite processing, to produce a wide range of micron size of chemical purity, outstanding brightness and controlled particle size distribution.

You can choose MTM , MTW or SCM to grind calcite into the very micron size production .

MTM Mill MTW Mill SCM Mill MTM Trapezium Mill is a world leading level industrial mill.It is designed by our engineers and technical workers ,basing on many years industrial mill design ,adopting world leading powder making teachnology.

High grinding efficiency Inverted trapezium roller and ring can reduce materials' slip velocity. - Steady and low noise Press spring keeps the balance. Resilient connection ensures reduces noise. - High grain finesse Product powder precision is improved by 50% compared with Raymond mill.

MTW continencial trapezoid mill are designed by our experts, according to advices of customers' long-term experiences. They adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology.

Special transmission Bevel gear integral transmission compact structure and simplify installation. - Efficient lubrication Bearing lubrication realized without oil pump or lubrication station. - Long service time Curved surface edge of alloy material is more wearable and easy to be changed.

SCM Super-micro Mill is a new type of making micro powder machines through more than twenties times research and improvement, depending on two decades of hard work & experience and bringing in the latest mechanical techniques of Sweden.

Adjustable high finesse Powder finesse can reach D97≤5um, and adjustable between 325~2500mesh. - High cost performance Capacity improved by 40% compared with jet mill and mixing mill. - Reliable security No bearing wear, no sealing elements wear, no bolt in the chamber. - Environmental friendly Equipped with pulse filter and sound absorber, the mill reaches environmental-protection Standard and reduces dust and noise greatly.

Calcite grinding process
Firstly,calcite shoud be crushed by the jaw crusher to the size specified, and then the crushed stuff is elevated into a hopper from which the stuff is loaded, through the vibrating feeder,evenly and continueously into the grinding chamber for power-processing. After this ,the ground stuff is carried by the air from the blower into the Classifier for screening.The fine powders are blow into the cyclone collector and are poured out through the out-put powders valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding, thus it can produce wide range powers of different size which you need, such as 600mesh, 800mesh, 1025mesh,etc.
