RM Series Raymond Mill

Since the introduction of Raymond mill in China for more than 20 years, it has been widely used in the processing of non-metallic minerals. However, with the extensive development of non-metallic minerals in the field of ultrafine powder application, downstream enterprises have higher and higher requirements for non-metallic mineral products, especially for product fineness, which makes traditional Raymond mill seem inadequate.
For this reason, the essence powder Technology Department has conducted in-depth analysis and research on the traditional Raymond mill, and solved many fatal defects such as frequent maintenance, high maintenance cost and substandard grinding fineness of the traditional Raymond mill, and developed a new ultra-fine Raymond mill that integrates crushing, grinding and ultra-fine.

RM Series Raymond Mill

How it works

The main machine drives the central shaft to rotate through the double belt combined transmission mechanism, the upper end of the shaft is connected with the plum frame, the grinding roller and the plum frame are installed together to form a dynamic grinding system, and form a swinging fulcrum. When the frame rotates, the grinding roller is pressed to the outer grinding ring by centrifugal force, forming a complete set of crushing combination, and the grinding roller rotates around the grinding ring by friction.
With the strict shovel system, it is located in front of the grinding roller and below. During operation, the material is thrown up and fed between the grinding rings of the grinding roller to form a crushing material layer. The material layer is crushed by the extrusion and friction generated by the rotation of the grinding roller, so as to achieve the purpose of grinding.

Equipment advantages

01 Flexible installation

The mill is installed on the ground, and the ground part is 50% of the height of the traditional mill, which reduces the height of the plant, saves the investment of the plant, and is more conducive to equipment maintenance.
02 Reliable and durable

The roller bearing seal is a new sealing method, which realizes maintenance-free and oil-free. Eliminate bearing powder, greatly reduce equipment maintenance costs.
03 Easy Maintenance

The graded cavity adopts suspension structure, which can automatically lift and shift to reduce equipment resonance, reduce noise and improve maintenance convenience.
04 Innovation upgrade

Innovative grinding ring and roller design, optimize the circular arc occlusion mode, compared with the traditional Raymond mill, reduce the falling speed of materials through the grinding area, prolong the crushing and crushing time, and combine the broad feed particle size requirements of Raymond mill and the ultra-fine grinding function of ultra-fine mill, crushing, grinding and ultra-fine in one step, the fineness can reach d90:10um.
05 Easy to Operate

The rotary boom mounting structure of the classifier avoids the resonance between the host and the classifier, reduces the vibration of the equipment, reduces the running noise, eliminates the input of lifting maintenance tools, and the open maintenance operation increases the convenience of operation.
06 Reduce Cost and Improve Efficiency

The intermediate tangential cyclone air intake makes the material in the grinding and grading chamber in a vortex rising state, more conducive to the extraction of coarse powder, reduce fan energy consumption, reduce production costs.
07 Green Environmental Protection

The whole system runs under negative pressure without positive pressure zone, and the production environment is extremely good. The dust emission concentration is better than the national standard and reaches ≤30mg/m3
