Raymond roller mill for mineral making powder grinding

Raymond roller mill is a widely used grinding equipment in the mineral processing industry. It is mainly used for the grinding of non-flammable and non-explosive brittle materials with a Mohs hardness below 9.3 and a humidity below 6%. The Raymond roller mill has the advantages of high efficiency, low energy consumption, small footprint and good environmental protection. It is an ideal grinding equipment for the mineral processing industry.

Working principle

The Raymond roller mill is mainly composed of a main machine, an analyzer, a fan, a cyclone separator, and a dust collector. The main machine is composed of a frame, a grinding roller device, a grinding ring, a discharge device, and a transmission device.

The working principle of the Raymond roller mill is as follows:

1. The materials to be ground are fed into the grinding chamber of the main machine from the feeding port.
2. Under the action of the centrifugal force generated by the rotation of the grinding roller, the grinding roller rolls on the grinding ring, and the materials are crushed by the rolling and pressing action of the grinding roller.
3. The crushed materials are carried to the analysis machine by the air flow generated by the fan.
4. The analyzer separates the qualified materials from the unqualified materials. The qualified materials are sent to the cyclone separator for collection, and the unqualified materials are returned to the grinding chamber for regrinding.

Features

The Raymond roller mill has the following features:

• High efficiency: The Raymond roller mill has a high grinding efficiency, and the output is 1.5-2 times higher than that of the ball mill under the same conditions.
• Low energy consumption: The Raymond roller mill has a low energy consumption, and the power consumption is 30-40% lower than that of the ball mill under the same conditions.
• Small footprint: The Raymond roller mill has a small footprint, and the area occupied is only 50-60% of that of the ball mill under the same conditions.
• Good environmental protection: The Raymond roller mill has a good environmental protection effect, and the dust emission is less than 10mg/m3.

Application

The Raymond roller mill is widely used in the following industries:

• Cement industry: The Raymond roller mill is used to grind cement clinker and raw materials.
• Metallurgical industry: The Raymond roller mill is used to grind ores and concentrates.
• Chemical industry: The Raymond roller mill is used to grind various chemicals.
