Rotary kiln belongs to building material equipment, and it can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.
Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
Each machine, each type has its certain rotary speed when it was be designed. As all we known high speed will have high capacity. But control it to be some certain is very important. High speed, intensified campaign, also the raw material has its own energy, so the over crushing will be occurred in the grinding.
Taking ball mill as an example, Type 1224. As we all known that its rotary speed is 27-34 r/min, if we increase the speed to the 36 r/m, the capacity will be get by 4.2%. In this condition, Capacity of the size below 5mm will increase from 11% to 15%, and the metal will be 4% to 5.2%.
Now in the market, the popular and agreed grinding machine include the ceramic ball mill, energy-saving ball mill and rod mill. The ball mill has the advantages of smaller size, even size and can apply to the grinding of the quartz and feldspar. The ball mill has bigger output size so it can avoid the damage by “over crushing”. So as the grinding machine, control the rotary speed is benefit.
With its high quality products such as Screw classifier?Stone production line?Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
