Chalk Powder Making Machine

Chalk Powder Making Machine

Application of Chalk powder making machine:

Chalk powder making machine is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice, etc., totally more than 100 kinds of materials.

Work Principle of Chalk powder making machine:

First the materials are crushed by the jaw crusher, then the crushed materials are transferred to a hopper by the elevator uniformly. quantltatively and continously by the vibration feeder to the grinding chamber of the main frame for grinding.the grinded particles are brought up by the air current of the blower into the classifier for classification. the particles with the required fineness are brought up by the air current through the pipe into a collector for separation and collection,the finished particles are discharged from a pipe outlet,Because of some moisture contained in the materials to be grinded,the heat resulting from grinding leads to the vaporized air which changes the airflow volume,Moreover,the outside air inhaled from the narrow gaps of the piping connections can increase the volume of air current.Therefor,it is necessary to adjust redundant air pipe between the blower and the main unit for keeping the balance of the air current.Then the redundant air is quided into a cloth bag of a dust cleaner to collect the fine power in the air,Finally, the redundant air is discharged after purfication. Chalk powder making machine mainly consist of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

chalk machine mill features and benefits

In the micro-power grinding room, the rollers hanged on the roller lifting frame, which is fixed with the main shaft and the scraper knife. the pressure spring press on the outer of the cantilever by tension rod, with the corss arm shaft as the supporting point. let roller tightly press on the inner surface of the ring. when the motor moved with equipment, the scraper knife on the scraper frame moved with the roller at the same time. as the roller moved on the inner sphere surface and moved itself. analyzer let the analyzer runner rotated by motor equipments, and the power fineness depend on the speed adjustment of the analyzer.

Features of Chalk powder making machine

1.High Efficiency

Under the same finished final size and the same motor power, the capacity of Chalk powder making machine is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.

2.Long lifecycle of spare parts

The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcite carbonate.

3.High safety and reliability

As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.

4.High fineness, flexible adjustment

The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.

5.Environment-friendly

The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.

6.Advanced intelligent speed control device

Convenient adjusting, more uniform particle size.
