High Pressure Suspension Grinder mainly consists of host machine, fineness analyzer, air blast, cyclone powder collector, as well as bag-type dust collector, ventilation pipe. If required, it can be provided with accessories such as breaker, elevator, storage silo, magnetic vibration-actuated feeder and electrical control tank etc. In host machine, grinding roller module hangs on roller suspender through cross shaft.

Roller suspender, main shaft, and shovel blade shelf are connected tightly. Pressure spring on external face of grinding roller bearing chamber has grinding roller to closely pressure against the inner circle surface of outwear, by the cross shaft as support. When motor drives main shaft through gearing, the shovel blade on shovel blade shelf and grinding roller turn synchronously; while grinding roller turns within the inner circle of grinding ring, it rotates. The faster the impellers run the more fine the selected powders are.




1. Compared with the common Raymond grinder 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. It's 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.

Performance feature:
1. Under the same power condition, the output of the grinder is higher than that of others by an increment of 10% to 20%, and with the help of pressure spring, the rolling force on material introduced by grind roller increases by 800-1200kg.

2.High Pressure Suspension Grinder processes mineral materials Mohs’ scale of hardness less than 9.3 grade.

3.Size range of finished product is wide, with the maximum value 0.613 (30 mesh), and common 0.033 mm (30 mesh), the minimum 0.013mm (1000 mesh).

4. Aspirating result completely meets the national dust emission standard.

Precautions in use:
1. When construct factory, make sure that the host machine can hang 1.5-2 ton lift device whose purpose is for inspection.

2. Host machine and air blast must be placed on reinforced concrete floor horizontally. After the equipment installment, we are allowed to pit, pour concrete under the stabilizers of cyclone powder collector and dust catcher.

3. During installment, each flange of connection pipes should be added with sealing plate.
