In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Analysis of the advantages and disadvantages of Raymond Mill

Raymond Mill, also known as Raymond Mill, high-pressure suspension roller mill, is a widely used milling equipment. Raymond mill is a widely used grinding equipment for mines, cement plants and chemical plants. It is one of the important equipment for deep processing of non-metallic minerals.

First, the advantages of Raymond mill.

Although different types of Raymond mills have their own advantages and performance characteristics are different, but in general, Raymond mill has the following advantages:

  • 1. The entire Raymond mill is a vertical structure with a relatively small footprint, strong system and strong complete set. Whether it is roughing or conveying raw materials, milling and final packaging, it can be used as a self-contained one. Independent production system.
  • 2. The electromagnetic vibrating feeder is uniform in feeding, easy to adjust, small in size, light in weight, energy-saving and power-saving, and easy to maintain.
  • 3, electrical can achieve centralized control, in the host computer room can achieve unmanned operation.
  • 4. The main drive unit adopts a closed reducer, which has stable transmission and reliable operation.
  • 5, Raymond mill compared with other milling equipment, the high screening rate, through the Raymond mill grinding the finished particle size screening rate can reach more than 99%, which is not achieved by other milling equipment.

Second, the shortcomings of Raymond Mill

With the extensive development of non-metallic minerals in the field of ultra-fine powder applications in recent years, downstream enterprises have higher and higher requirements for non-metallic mineral products, especially for product fineness. Some problems with traditional Raymond mills have plagued mineral processing companies and equipment manufacturers. These problems are mainly manifested in:

  • 1. The crushing and grinding ability is low. The fineness of the powder produced by ordinary Raymond mill is generally below 500 mesh, which can only occupy the lower end powder application market.
  • 2. The mechanical failure rate is high, the power consumption is large, the noise is large, and the emission pollution is large.
  • 3, the system efficiency is low, the product separation system separation effect is not ideal, a large number of fine powder can not be effectively collected and repeated circulation in the system to cause power waste.
  • 4. The design of the main air box duct is not scientific enough. The larger particles entering the material of the grinding area and the particles that have been ground in the future are often thrown into the bellows and gathered at the tail of the volute, and continue to extend forward, so that the amount of over-wind is gradually reduced. Causes traffic jams, no powder or less powder, affecting production.

In order to solve the problems of the traditional Raymond machine and adapt to the needs of the market, many Raymond mill manufacturers have improved and improved the Raymond mill, although these problems have been improved through the efforts of Chinese manufacturers and R&D personnel. The new Raymond mill began to occupy the market.
