Product Description

Raymond mills are widely used in the grinding and processing of mineral products in metallurgy, building materials, chemical industry, mining and other fields. 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 combined action of the analyzer and the fan, it can meet the requirements of different users.

Product Features

Unique design and higher yield： The roller hanger is fastened with a high-pressure spring with a pressure of 1000-1500 kg. The grinding force of the grinding roller on the material is increased by 800-1200 kg under the action of the high-pressure spring, and the output is increased by 20%-30%.

Wide range of finished product particle size： The particle size of the finished coarse powder can reach 0.613 mm (30 mesh) and the particle size can generally reach 0.033 mm (425 mesh), and the fine particle size of a small number of materials can reach 0.013 mm (1000 mesh).

The analysis machine is easy to adjust： The analysis machine adopts frequency conversion speed regulation, which is more energy-saving than electromagnetic speed regulation, accurate adjustment control, good process control maneuverability and high degree of automation.

Multi-stage sealing, good environmental protection effect： The grinding roller device adopts overlapping multi-stage sealing, which has good sealing performance and the dust removal effect fully conforms to the national dust emission standard.

Working Principle

The whole structure of Raymond mill consists of main engine, analyzer, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main engine consists of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. When working, the materials to be pulverized are fed into the machine from the feeding hopper on the side of the main machine shell, and rely on the grinding roller device suspended on the main machine's plum blossom frame to revolve around the vertical axis, and at the same time rotate itself. , the grinding roller swings outward and presses against the grinding ring, so that the material shoveled by the shovel blade is sent between the grinding roller and the grinding ring, and the rolling surface of the grinding roller achieves the purpose of crushing the material.
