Copper (Chemical Cu) Ball Grinding Machine Noise Number The noise from steel balls from the impact of the village plate, with a large relationship with the damping of the liner material. The ball mill is a crushing key equipment after the material is broken. The lining of the fiscular mill is mainly made of high manganese steel, low, medium, high-grade cast iron (CAST IRON) and rubber (Rubber). High chromium (chromium) cast iron loss (Sǔn hào) factor is large, the damping is higher than high manganese steel, and the noise when the steel ball is hit, so the ball mill noise of high stuffing iron liner is low 2 \u0026 mdash; 3DB. Rubber is a viscoelastic material, which has good vibration damping performance (function), pulling the rubber, the ball mill noise can be reduced by 8-10 dB.
The lining plates used in the ball mill have wavy, stepped shape, the ball mill, the liner inclination and the friction coefficient, and the lift effect of the steel ball is different in the same speed, resulting in steel ball impact force. Body noise difference. The ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metallogenicity and glass ceramics, etc., dry or wet grinding of various ore and other wear materials. . The lining is large, the high height of the steel ball is small, the resulting impact noise is low; the friction coefficient is large, and the height of the steel ball is high, the resulting impact noise is large.
The arrangement of the liner is also affected by the noise of the cylinder, and the liner is arranged in a horizontal line, which is easy to make the polishing movement discontinuous (Continuity), the load fluctuations, and the resulting noise is large. Spiral step arrangement and human font layout, can reduce the axial vibration and donor fluctuation of the cylinder, which can reduce the cylindrical noise.
The impact noise size of the ball mill is proportional to the steel ball diameter, and the steel ball diameter can effectively reduce impact noise. The ball mill is a crushing key equipment after the material is broken. However, the steel ball is reduced, and the ability to impact the crushing coal block is also reduced. For the same weight, the grinding body is used, and the equivalent diameter is reduced, which can reduce the cylindrical noise.
Common Power Plant Boiler Combustion Use Coal to have a smokeless coal, tobacco coal and lean coal. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill. The ball mill is a crushing key equipment after the material is broken. Smokeless coal has high carbon (C), low volatile, hard, absorbing steel ball impact, low carbon, is lower than smokeless coal, soft texture, reducing the impact of steel balls than smokeless coal. When the coal particles are large, the ball mill noise of grinding is more than the grinding smoke coal. As the coal particles decrease during the grinding process, the ball mill noise gradually tends to be close.
