Superfine powder equipment domestic development situation

Along with the development of nonmetallic industrial revolution, nanometer technology is widely used. The research and development of superfine powder equipment is more and more rapidly, such as: jet mill, vibration grinding, impact grinding, superfine ball mill etc, above all have their own unique equipment the crushing mechanism, but there is a common faults large energy consumption. I company scientific research personnel in the research on the basis of the equipment developed out of the generation of new patented product, it absorbed the advantages of the equipment and its shortcomings. customer service with shock, extrusion, grinding the crushing mechanism, make the joint material is fully, thoroughly shattered.

The advantage of LG9920 ring milling superfine grinding mill

1, Grinding unique way: the grinding rolls are hung in grinding ring parallelly , milling roller and grinding ring have 6-8mm clearance, grinding roll and grinding ring,do not contact directly . The grinding ring driven by material rotates the grinding roll, and the grinding roll by two spring high-pressure pre-tightening force makes the material crushing and grinding.

2, Because the grinding roll and grinding ring do not directly contact , the content of iron in material is low, and not to drop white degrees.

3, Stronger grinding force: grinding force of grinding roll generates from both root of preloaded force high-pressure spring (about 4000Kg) .the force is three times of 4R3216 raymond mill’s grinding force.

4. Bigger grinding surface.

5. Finished granularity: the finished granularity reaches 2,000 mesh.

6. High output, low energy consumption: the output of 1250 mesh calcium carbonate is above 1.5 ton/hour.

Working principles of LG9920 ring milling superfine grinding mill

Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.
