Raymond mill is one of the important equipment for deep processing of non-metallic minerals. Because of its stable performance, strong adaptability, high cost performance, since the introduction, it has been used for more than 20 years in our country. Raymond Mill has been popular used in the processing of non-metallic minerals. But as theultrafine powderof thenon-metallic minerals in recent years is widely used in the field of application development, downstream enterprises pay more and more attention to the requirement ofultrafine powder ofnon-metallic minerals. Especially for product fineness which field has higher requirements. This makes the traditional Raymond mill ragged.

The problems of traditional Raymond mill has been plagued by mineral processing enterprises and equipment manufacturers. These problems mainly displays in:

1. Low product fineness, ordinary Raymond Mill grinding fineness generally below 500 mesh, the equipment can only capture lower-end powder application market.

2. High mechanical failure rate, big power consumption, noise, and exhaust emissions big

3.System efficiency is low, the product collection system of the separation effect is not ideal, a large number of fine powder can not get effective collection and in the system of repeated cycle power waste

4. Host had made a mistake, bellows duct design into the grinding zone material before the larger particles and grinding crushed particles are often gathered in cochlear box into bellows tail, and extends forward and make the air volume gradually reduce, easy cause traffic jams, not powder powder or less, affect the production.
