Material grinding production in the use of ball grinding mill, processing ability of different material quality, hardness mini crusher, shape and other aspects of the ball mill also have different effects.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:mobile crusher,mini stone crusher machine,We will provide you with the best product and service. 1. Hardness requirements. Ball grinding mill material hardness requirements are relatively high, the better the performance of hardness and better material is corrosion resistant, easier. 2. Toughness requirements. The material is not easy to break in the grinding process, with more resistance ball mill, such as thermal shock resistance, compressive ability, this will make the material can form a cutting edge sharp in times of ball grinding mill grinding, grinding more times better. 3. Shape and size requirements. In order to become good grinding products, its shape should be uniform, in the shape of the material small stone crusher, ratio of long, wide, high material if 1:1:1 is the best. 4. Density requirements. The accumulation of material density reflects the material per unit volume has quality portable stone crusher, but also to some extent reflects some properties of materials, bulk density, better grinding more refined. 5. Hydrophilic requirements. This depends on the specific grinding; wet grinding is needed to have certain hydrophilic material. 6. Stability requirements. In ball grinding mill high-temperature environment material should maintain the original properties and hardness, at the same time in the grinding process of material should be chemically stable, not easy to produce chemical reaction.
