Product Description
Luoyang Shuangyong high pressure raymond mill is a newly patented product designed by our general engineer on the basis of research experience and actual condition of grinding mill from the customers focusing on the need of industry development which has initiated a new era of high-efficient and low-energy consumption for international gringding industry. It is suitable for processing various non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%, primarily used for powder processing of mineral products in industries such as metallurgy, building materials, chemical, mining, expressway construction, water and electricity industries and so on. It is an ideal choice for processing materials such as quartz, feldspar, calcite, limestone, talc, ceramics, marble, granite, dolomite, bauxite, iron ore, bolognian stone, alta-mud, gangue and coal with finished particle size between 80 to 425 mesh, adjustable to the minimum of 1000 mesh. On the other hand, it can produce cribble of 30 to 80 mesh by adding special device.

Advantages and Features
Good effect in sealing;
Strong material applicability;
Classer easy to adjust;
Higher yield under same power;
Grinding pressure increased by 800-1500kg;
The finest finished size can reach 1000 mesh;
Dedusting effect fully meets the national standards.
Working Principle
Materials are firstly crushed by jaw crusher, then transferred to grinding area by electromagnetic feeder through the elevator and lifted by the shovel to the sand belt formed by grinding roll and grinding ring. High-pressure springs are installed in the grinding device, helping improve rolling ability between grinding roll and ring by 1.2 times, reducing the swing frequency of grinding device, increasing stability and working efficiency of the mill at the same time. The grinded particles are brought up by the air current of the blower into the classifier for classification. The particles with required fineness are brought up by the air current through the pipe into a cyclone collector for separation and discharge while the unqualified returns to the main machine for a new grinding together with the air flow back to the blower. During the course of grinding, certain air flow circulates inside the machine through the pipe while the moisture of materials envaporates to the air return pipe and is purified by the cloth collector or pulse collector and finally discharged from the outlet.
