Diatomaceous earth is a siliceous sedimentary rock. The mineral composition is opal and its variants. It is fine, loose, light, porous, water-absorbing and penetrating. It is commonly used in the industry as insulation materials, filter materials, fillers, abrasive materials, water glass raw materials, decolorizing agents and diatomaceous earth filter aid, catalyst carrier, etc.
Among them, in the food industry, diatomaceous earth is mainly used as a filter aid for filtering fine suspended matter, colloidal substances and other harmful substances. It is widely used in the production of various foods such as beer, beverage, juice, vegetable oil and syrup.
Crushing is an important part of food grade diatomaceous earth filter aid, and the fineness of the filter aid for food is strict. Therefore, the performance of the diatomite mill will directly determine the quality of the filter aid.
Kefid MW ultra-fine powder mill is a new type of equipment which draws on Swedish grinding technology and designed for ultra-fine powder processing users. It is mainly suitable for non-flammable and explosive materials with Mohs hardness below 9 and humidity below 6%, such as diatomaceous earth, kaolin, calcite, calcium carbonate and talc.
MW ultra-fine grinding mill adopts the continuous grinding method of the extension, and the material is subjected to multiple cycles of grinding at the same time. The grinding efficiency is higher, the output is 45% higher than the airflow mill, and the finished product has finer grain size, and the final fineness of the finished product can reach D97 ≤5μm (adjustable between 325-3250 mesh). It can fully meet the powder fineness requirements of filter aids in the food industry. At present, it has become a universal application equipment in the field of diatomite ultrafine powder processing, and its durable and environmentally friendly quality has been unanimously recognized and praised by customers all over the world.
