Stone processing plant (powder processing plant) designed by our engineers and technicians on the basis of multiple innovation, test and experience over two decades, has absorbed many advantages of home and abroad mill manufacturing technique. It is specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, the moisture under 5% 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.

Benefit of stone processing plant

1.High Efficiency.
Under the same finished final size and the same motor power, the capacity of the 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?5?m.

5.Environment-friendly.

Working Pinciple of stone processing plant:

1) After crushed by hammer crusher, the large materials become smaller pieces and are sent to the micro powder grinding mill.

2) When the micro powder grinding mill is at work, the granulated materials are crushed and grinded by the rollers into particles below 47micron.

3) The high-pressure air blower constantly inhales air within the micro powder grinding mill.

4) Along with the high speed airflow, micronized materials are brought to the classifier.

5) The qualified particles are screened and driven into the cyclone powder collector, finally exit from the discharging valve at the bottom;

6) A small proportion of the fine powders, with airflow, moving to the dust cleaner. Filtered clean air will be emitted from the air outlet of muffler in the end.
