As we all know there are two ways can be used when we use calcite ball mill to process calcite powder. In general, dry grinding and wet grinding are related to material properties, such as reactivity with the abrasive medium. When grinding, attention should be paid to the selection of the grinding body and the ball to material ratio. The wet grinding efficiency is higher, but the energy consumption is greater.
Ball mill is divided into dry grinding and wet grinding. Wet grinding is the most commonly used method, with high efficiency and uniform ball mill. Because the particles in the ball mill process, large particles in the grinding medium grinding and impact, there will be cracks, crack propagation over time will break into small particles, that is called the grinding process. If it is dry grinding, then the particles during the grinding process of crack propagation, the extrusion ball or between particles, the formation of cracks may be squeezed, "closed" crack cannot be effectively extended, large particles will not fracture the formation of small particles, but if it is wet grinding, then the liquid grinding medium will enter the crack gap the block crack closure, which will effectively make rapid crack propagation down, will greatly improve the efficiency of ball mill.
For dry grinding, the general is aimed at the liquid medium does not respond to the material, if there is reaction, then in the ball mill will form other substances, that ball mill is meaningless, for example: cement can not be ball mill in water. At the same time, dry grinding, due to the design of the ball mill tank, sometimes forming dead, dead in the portion of the material is milled to; but also have a weakness for wet grinding and dry grinding, wet grinding is powder after drying to remove water or other liquid medium, it will increase energy consumption and cost.
Above all, if you need to process calcite powder in calcite ball mill, the best way is use wet grinding method. Are you interested in calcite ball mill? If you are welcome to leave your inquiry on our website, our sales manager would contact you as soon as possible. Thanks fr your reading.
