REVIEW: high quality quartz powder used as a basis for industrial raw materials widely used in glass, ceramics, refractories, metallurgy, construction, chemical, electronics, optical and other industries. However, processed into high-quality quartz quartz powder is indeed a problem, the main equipment for domestic quartz grinding mill grinder and legislation. So, what is the best equipment for the processing of quartz powder is?

 

Quartz powder Introduction

Quartz powder, also known as silica powder, its color is white or colorless, translucent, Mohs hardness 7, no cleavage of brittle, preparation of raw materials quartz sand fineness generally 20 to 120 mesh, more than 120, said the purpose of the product quartz powder, the fineness of more than 325 projects are called quartz powder. Quartz powder processing, how to greatly improve the quartz powder mill production capacity while reducing the iron content of the quartz powder, quartz powder is the first large-scale production of technical problems to be solved.

Quartz powder processing Raymond mill: a quartz powder processing existing users before processing by Raymond quartz powder. Investigation that its grinding production of about 1t / h, not only inefficient, high energy consumption and product size is difficult to control. Raymond resistant materials with high manganese steel, high manganese are weakly magnetic, mechanical iron which are difficult to remove. In addition, there are invalid Raymond collision between the presence of wear-resistant materials, with higher fineness powder, iron content also significantly increased

Quartz powder processing mill stand: stand mill is the latest development of a set of crushing, drying, grinding, separator, one of the efficient delivery of low-energy grinding machines, high grinding efficiency, low energy consumption, bake dry capacity, product fineness is easy to adjust, the process is simple and so on. And production is relatively stable, generally 10 ~ 12t / h. The most important thing is to use vertical mill processing of quartz powder, wherein the iron is easily removed mechanically, the iron content of the product can meet the specifications. Therefore, the legislature has processed quartz powder mill "special adaptation", is the preferred equipment for processing of quartz powder.

 

Vertical mill processing characteristics of quartz powder

, the disc speed: To improve the efficiency of the grinding mill product fineness and mills, disc speed must be balanced and matched and materials are grinding speed. Due to the smaller size of quartz raw materials, so to reduce the rotational speed of the disc in order to ensure the effectiveness of quartz powder processing.
2, disc liners and grinding roller sleeve: quartz ultrafine grinding material on the disc contains a very fine 1 ~ 40μm fine particles, the production tends to vertical mill can not effectively biting a large number of particles of the group, causing the rollers sliding or front roller accumulation. Vertical roller mill grinding using tire type, disc using the bowl liner, the successful resolution of this problem. Not only to achieve an efficient grinding, also extended the disc jacket liner and grinding roll life.
3, wear-resistant materials design: quartz powder application industry has strict requirements for its iron content, so the vertical grinding mill rolls, wear-resistant material on the disc are made of high chromium cast iron, which can easily be mixed with quartz powder in the wear magnets attract, even a small amount of iron is also very easy to get rid of the mechanical quartz powder in.

Shanghai zenith production LUM series vertical roller mill has been successfully applied to the processing of quartz powder, said customer feedback very good run, is now exported to South America, Europe, South Africa and other regions. Welcome to the online consultation!
