LIME INDUSTRY GRINDING PROCESS

Grinding stage

The calcined lime raw materials via buffer hopper and cooling are directly (or crushed once) sent to the main grinding chamber continuously and evenly by feeder for grinding, and the ground fine powder is separated by the classifier under the action of the fan air flow and then sent to the air outlet pipeline to enter the collection stage.

Collection stage

The dust gas from the grind enters the cyclone collector through the main mill air outlet pipeline, and most of the finished fine powder is separated under the action of centrifugal force; At the same time, the excess gas is sent to the pulse dust collector, which is discharged into clean gas through the pulse dust collector, and the finished fine powder collected by the bag is transported together to the finished product conveying stage by screw conveyor.

Conveying stage

The finished ore powder collected by the dust collector and cyclone collector is sent to the bucket elevator by the screw conveyor, and then enters the finished product tank. The dust gas in the tank is collected by the dust collector top of the tank and the finished product is stored in the finished tank and clean gas is discharged.

Finished product stage

The lime powder obtained after grinding can be sent to the customer site for use directly, without additional downstream processing steps.
