Raymond Mill

Raymond Mill

≤35mm Feeding Size
3-22t/h Processing Capacity


Raymond mill is widely used in the grinding and processing of mineral products in the fields of metallurgy, building materials, chemical industry, mining, etc. It is suitable for processing various non-flammable and explosive materials with Mohs hardness below 7 and humidity below 6%. Between 613μm and 44μm, through the joint action of the analyzer and the fan, it can meet the requirements of different users.

Inheritance of Classical Design, Innovation of Science & Technology

Adopts the classical pendulum rollers of Raymond Mill on the one hand and change the spring connection structure innovatively on the other hand, which can not only avoid the terrible impact of large materials on the axis and bearings, but also enhance the crushing strength of grinding rollers so as to increase the yielding.

Lower Electricity Consumption, Higher Economic Profits

Under an ideal circumstance, Raymond Mill consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball grinding mill of the same level by over 60%.

Impeller-type Energy-saving Fan Having Higher Efficiency

SPOM adopts the high-efficiency impeller energy-saving fan, and the working efficiency of which can reach 85% or above while traditional grinding mills equipped with straight blade fan can reach only 62% of air inducing efficiency. Under the equivalent production requirements, Raymond Mill can realize better powder separating and lower power consumption.

Lower Energy Consumption - Cambered Air Duct

Raymond Mill uses the cambered air duct with low resistance. By this, air flow enters the grinding mill tangentially. Compared with traditional straight air ducts, the inlet of this air duct is smooth with little resistance and the outlet is easy for the dispersing of materials which can avoid material piling, effectively reducing energy consumption of the system.

Digitalized Processing, Higher Precision

Operations such as steel plates' cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

Sufficient Supply of Spare Parts, Worry-free Operation

SPOM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.


The whole structure of Raymond mill is composed of main engine, analyzer, piping device, blower, finished product cyclone separator, jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control motor, etc. Among them, the main engine of Raymond mill is composed of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. When working, the material to be pulverized is fed into the machine from the feeding hopper on the side of the machine casing, and revolves around the vertical axis by means of the grinding roller device suspended on the plum blossom frame of the main machine, and at the same time rotates itself. The grinding roller swings outward and presses tightly on the grinding ring, so that the shovel scoops up the material and sends it between the grinding roller and the grinding ring.
