ISO9001:2008 qualified company Guilin Mining Machinery Co., LTD., founded in 1973,the original Guangxi Guilin Mining machinery Factory is Chinese largest production base of mining machinery and equipment R Pendulum Grinder for national production .We have a more than 500 working stuff, in which about 60 are Senior technician, and a more than 75000 sq.standard working shop and office building. So that we can combine R&D, processing and manufacturing, marketing and sales, with after sales service into a whole. Till now, we have formed a whole production chain with 245 existing types of industrial equipment ,which include cast steel, cast iron , metal cutting , assembly 10 workshop separate parts factory, electronic factory.

  Our products cover more than 24 models of the 5 major series: mill series, crushing series, classifier series, dedusting series, sand making series. 




4R3220 Improved Pendulum Grinding Mill



1, Strong Grinding Force:

 The grinding force of roll is increased by super spring device, each of which is raised by 500kg, so as to improve efficiency largely.    

2, Expanding Grinding Area: 

The grinding area is expanded by heightening roll and ring from 160mm to 200 mm.

3, Strong ability of shoveling material:  

Adopting super large shovel blade to shovel as much as possible to the grinding area between the roll and ring.

4, High Classification Accuracy: 

Super large classification turbine brings a higher passing rate and stronger airflow. In addition, the labyrinth seal between the edge surface of blade turbine and powder outlet decreases the short circuit powder.

5, Dual Cyclone Collector: 

The collecting efficiency is up to 80% and 10% higher than single cyclone collector.

6,The rest powder is collected by sack ,so the workshop will be clean.

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.
