What are the advantages of the new Raymond mill?

What are the advantages of the new Raymond mill compared with the traditional Raymond mill? With the extensive development of non-metallic minerals in the application of ultrafine powders in recent years, downstream companies are increasingly demanding non-metallic mineral products. In particular, there is a higher requirement for product fineness. This makes the traditional Raymond mill seem incapable. These problems with traditional Raymond mills have plagued mineral processing companies and equipment manufacturers.

Process characteristics of the new Raymond mill

Based on the ultra-fine powder processing technology that we have mastered over the years, we have carried out comprehensive and thorough technological innovations on the above issues. When using the traditional Raymond mill, we found that the Raymond mill contains a large amount of 10um ultrafine ore powder in the processing of calcite mineral powder. If it can be separated and expanded, it will greatly improve the efficiency. . To this end, we have carried out a lot of renovations on the Raymond mill structure: the traditional way of the mainframe has been improved, and the main shaft and the plum blossom frame have been structurally modified to ensure stable operation.

There is no swing in the center. The traditional part of the analyzer is changed from the inside of the cavity to the two rotations in the cavity outside the cavity, thereby enhancing the stability and durability of the work. In the pulverizing section, the material to be ground is always gathered in the grinding and pulverizing zone for effective processing, and the grinding efficiency is improved. We also update the structure of the grinding roller so that the grinding roller and the grinding roller shaft can be complementarily operated. It can also be revolved at the same time as the rotation. Make it more powerful and durable. And can work at greater grinding power and higher running speed. In the ventilation part, the bellows and the air duct are changed from the original horizontal bottom to the center by 30 degrees to form a bucket shape, ensuring that the bellows and the air duct are always unobstructed, so that the air volume is always maintained, and the host grinding powder is in high efficiency. In the entire system design, from the traditional secondary collection to the four-level collection. The first and second collections are collected by circulating negative pressure lock-up type, no dust overflow, and the third and fourth level collections are collected by controlled overflow dry and wet series to prevent dust from overflowing. The entire system eliminates or reduces the pollution of the surrounding environment while collecting ultrafine powder.

The above-mentioned new Raymond mill can be used for superfine grinding of non-metallic minerals such as calcite, dolomite, talc, aged soil, barite, rutile, fluorite. After practice, the calcite with a feed size of 25mm is used for grinding. When the fineness is adjusted to 1250 mesh (10um), the output can reach 450kg/h, and the input power only needs 23kw. It is obviously more than the traditional Raymond mill. High cost performance.
