The ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recalculated back into the mill to be reduced. Various classifier, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.

The mixer is also called chute, which can make medicine and mash mix even enough .The mixer has advantages of simple and convenient operation, high efficiency, the material to be mixed more evenly, less time of mixing. The impeller and stator of the mixer are easy to wear parts. The impeller is made of high hard wear-resisting material, which is long service life, low failure rate, long replacement cycle, and reliable operation, and which can be connected with flotation machine to form production line and reduce production process, and improve comprehensive benefits.

The crushing rate of ball mill is not only related to the ore grinding condition, but to the property of the ores. When enlarged the crushing rate, the existing research mainly takes into consideration the average ball diameter and the distribution of the ball diameter, the diameter inside the grinding machine, adding ball ratio, filling voidage and the rotary rate of the grinding machine. However, the main purpose of the consideration lies in the enlarging design of the machine, but the problem is the scholars are unable to know the ball proportion situation inside the equipment, nor the above-mentioned factors could reflect the influences of the material flow and the amount of the water added.

For this reason, the experts of powder grinding equipment of Hongxing Machinery identify the function of the crushing rate in the practical production data. They established a model with the granularity distribution, operational conditions and the chemical composition of the rocks, and they think that the original model using several parameters to reflect all the changes in the grinding process is not appropriate and the crushing rate cannot be measured directly. As a result, they established a relationship model of the crushing rate function and the production conditions, thus realizing soft measurement of the crushing rate function and strengthening the practical applicability of the model.

Ball mills Double-row self-aligning spherical roller bearing replaces Babbitt-lined bearing. Friction resistance is significantly lowered down, effortless to begin and 20-30% of power is saved. Ball grinders Grooved Magnesium Kiln and ringed liner raises contacting surface area in between balls and ores, enhancing milling impact and saving power via its lifting impact for the materials. Ball grinders All-in-one frame is employed in middle-sized or small-sized machinery, facilitating engineering design and gear installation. Ball mills big discharging outlet and large capacity, discharge coarse particles, usually employed in very first phase Rotary kiln milling. The Energy-saving Cone Ball Mill may be employed for grinding particles with the procedure of material mineral resources, for instance gold, silver, iron, copper, lead, zinc etc., and non-metal mineral resources.
