  • HCM

Raymond mill is specific used for grinding mineral ores of fineness 80-400 mesh. HC pendulum Raymond mill is an upgrade equipment with a higher grinding efficiency. Raymond mill is mainly applied in the grinding process of metallurgy, building materials, chemical, mining & mineral industries, and suitable for grinding medium hardness materials and soft materials of less than 7 Moh`s. The unit is used as a cement grinder, clinker grinder, gypsum grinder, limestone grinder, coal grinder, talc grinder, spar grinder, dolomite grinder, marble grinder, slag grinder. It can also be used to grind granite, to grind quartz, to grind sandstone, and so on.

 

The Hcmilling (Guilin Hongcheng) brand roller mills are a very reliable, powerful and efficient type of the milling equipment. Efficient closed-circuit systems with exact fineness control, final powder with relatively narrow particle size distributions.

 

 

Features:

·Reliable performance: using new technology plum blossom frame and pendulum roller device, the structure is more advanced. The whole set of equipment runs smoothly and its performance is more reliable.

·Energy saving and environmental protection: equipped with a pulse dust collector, the dust collection efficiency is as high as 99%, all the positive pressure parts of the host are sealed, and the dust emission is less. Unit power consumption cost is saved by more than 30%.

·High efficiency: our unique technology improves grinding process efficiency, the primary grinding process can be intensified for hard ores and material transport can be improved for soft ores.

·Easy to maintain: no need to remove the grinding roller device for replacing the grinding ring, much easier to maintain.

Working principle

 

The coarse material is fed to the center of a round table rotated by an electric motor with gearbox. The material spreads down the slope of the central pile and further by centrifugal force. Conical grinding runners are pressed on the rotating material bed by means

of hydraulic or pneumatic and occasionally also by spring force. The ground material passes a retainer ring at the periphery of the table, where it is picked up by a swirled air stream drawn from the lower part of the mill and lifted completely to the inlet of an internal separator. The coarse fraction is returned to the center of the table.

From the separator outlet the final product reaches cyclones or filters for separation from the air, which is fully or partially recirculated to the grinding mill. The entire circuit is under negative pressure for dust free operation.
