The high pressure suspension grinder is mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. High pressure suspension grinder can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, such as quartz, feldspar, calcite, talcum, barite, fluoride, Xircom, cinder, white lime, cement clinker, activated carbon, dolomite, granite, soft coal, coking coal, lignite, magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, kyanite, fluorspar, bentonite, medicinal stone liparite, diabase, pyrophyllite, shale red stone, emeraldite, basalt, gypsum, graphite, carborundun, heat insulating material, etc.

Features
1. Compared with the common Raymond grinding mill under the same power conditions, the capacity can be increased by 10%, under the performance of high-pressure springs, the rollers grinding pressure on raw materials can be raised by 1500kgf.2. All the mineral materials with Mohs hardness below 9.3 can be crushed.3. The final product size ranges from the maximum particle diameter of 0.95mm (20mesh) to the finest diameter of 0.038mm (400 mesh). A few materials can reach 0.013mm (1000 mesh).4. Its dust-removing effect fully meets the national dust discharge standard.5. The classifier is easy for adjustment.6. The grinding device adopts a superposition multi-grade sealing with good sealing performance.

Working principle
The whole system of high pressure suspension grinder consists of main frame, decelerator, classifier, piping device, blower, jaw crusher, dustpan elevator, electromagnetic vibration feeder, and electric switch box, motor, etc.
1, Materials are firstly crushed by the jaw crusher; then the crushed materials is transferred to a hopper by the elevator and fed uniformly, quantitatively and continuously by the vibration feeder in the grinding chamber of the main frame for grinding. The grinding 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 cyclone collector for separation and collection and the finished particles are discharged from a pipe outlet.
2, Due to some moisture contained in the materials to be grinded, the heat resulting from grinding leads to the vaporized air which changes the ai
