Dry stirred mill: dry process, energy saving, wide application, high efficiency, and no pollution.
The dry stirred mill is an important ultra-fine grinding equipment. It combines a stirrer with a grinding cylinder. Through the rotation of the stirrer, the grinding media (such as ceramic balls, steel balls, etc.) grind the materials. In the absence of a liquid medium, the materials can achieve ultra-fine grinding effects.
Features:
(1) High grinding efficiency: The high-speed rotation of the stirrer makes the grinding media generate strong collision, shear, and friction forces, which can quickly and effectively grind the materials to ultra-fine particle sizes.
(2) Narrow particle size distribution: A relatively uniform particle size distribution can be obtained, and the product quality is stable. This is very important for some applications with high particle size requirements.
(3) Wide application range: It is suitable for grinding various materials, including ores with high hardness, ceramic materials, and chemical raw materials.
(4) Energy saving and environmental protection: Compared with wet grinding, dry grinding does not require dehydration and drying treatment, saving energy and water resources, and also reducing the cost of wastewater treatment.
(5) Simple operation: The structure is relatively simple, and operation and maintenance are convenient. It has high stability and low noise during operation.
(6) Avoid material pollution: If appropriate linings and stirrer component materials are used, metal impurities can be avoided from polluting the materials and ensuring the purity of the products.
Application fields:
(1) Mining field: Used for ultra-fine grinding of ores, such as grinding of heavy calcium carbonate, talc, quartz and other ores, providing high-quality raw materials for subsequent beneficiation, purification and other processes.
(2) Chemical field: Crushing chemical raw materials, such as pigments, coatings, plastic additives, etc., to improve the dispersibility and reactivity of materials.
(3) Ceramic field: Preparing ultra-fine powders of ceramic materials for the production of high-performance ceramic products such as ceramic capacitors and ceramic cutting tools.
(4) Powder metallurgy field: Grinding metal powders to ultra-fine particle sizes to improve the formability and sintering performance of powders and manufacture high-quality powder metallurgy parts.
(5) Electronic material field: Used for the preparation of electronic ceramics, magnetic materials, semiconductor materials, etc., to meet the strict requirements of the electronics industry for material purity and particle size.
