Ore dressing plant in the grinding fineness of the close relationship between the level of cost, how effective and reasonable control of the grinding fineness is directly reducing mineral processing costs, improve the economic efficiency of the processing plant.The grinding fineness is one of many factors affecting the beneficiation index, the size of the grinding fineness directly affect the level of concentrate grade and recovery of products.
Low cost of efficient raymond grinding mill
Raymond Mill complete configuration includes a hammer crusher, bucket elevators, storage silos, vibration feeder, micro grinding hosts, frequency classifier, double cyclone powder collector, pulse dust removal system, high pressure air,air compressor, electrical control system. Equipment in the case of the same product fineness and the motor power than airflow mill, mixing mill, ball mill production more than doubled. Grinding roller and grinding ring using special materials forging the system, thus greatly enhance the degree of utilization. Materials and finished product fineness of the same case, longer than the impact crusher and turbine crusher wear parts life of 2-5 times, usually up to one year or more, the processing of calcium carbonate, calcite, the service life of up to 2 5 years. Bearings, grinding cavity without screws, so there is the problem of the bearings and seals vulnerable, there is no screw loosening and destruction of the machine. Product fineness, the pulse filter to capture dust, and a muffler to reduce noise, environmental protection, and clean.
Reduce the cost of cement grinding mill
The cement production process, material grinding power consumption accounted for 70% of the power consumption of a direct impact on the manufacturing cost of the cement. Active use of new technologies and processes, to improve the yield of the grinding system, lowering the unit power consumption is to reduce production costs, improve the economic efficiency of enterprises is the most effective technical means. Active use of new techniques, new technologies, new materials, and greatly improve the production efficiency of the grinding system, to reduce power consumption costs. Into the grinding material particle size is an important process parameters of the constraints mill grinding efficiency. Especially for cement grinding, the grinding material physical and chemical properties and microhardness of different grindability index difference in raw material composition of materials. It must take reasonable technology, the implementation of the pretreatment before grinding materials, narrowing the particle size into the mill “more crushing mill” moved to the fragmentation function of some or all of the mill a position outside the mill, in order to substantially improve the existing grinding system output, lower grinding power consumption.
Pre-grinding the material into the mill before the other crushing and grinding equipment pre-grinding, ball mill coarse grinding position moved to the mill before the processing, instead of part of the low efficiency of ball mill with high efficiency grinding equipmentand reduce the particle size into the grinding clinker grinding system in order to improve yield and reduce power consumption.Industrial cement ore demand increases, the milling machine manufacturers, according to the status quo, the development of a variety of mill for cement in the pre-grinding process, to achieve high yield and efficient production.The vertical milling machine, vertical mill to replace the high stability of the ore mill for cement pre-grinding, cement grinding production increased by 40% -60% effective.
