subject: How To Improve The Output Of Grinding Equipments [print this page] With the continuous progress of the powder grinding technology, high-precision, many varieties of stone Fen fen demand has become stronger; powder widely used in rubber, paper, paint, plastic, aluminum, ceramic, cement, glass, metallurgical, refractory, medicine, food, household chemicals, technology, construction, advanced decoration production applications. In particular, can directly reduce the titanium dioxide used in paint and paper on use of 3% - 10%, thus greatly reducing the cost of the product.
How to improve the yield of the milling equipment, Henan Hongxing summed up its own set of methods in practice:
1.Scientific planning to use a different mill
Production practice proves that the Raymond mill for the brittleness of the mineral is more meaningful. Mill row of ore faster, Shen pulp underlying density of mineral particles easily discharged, a rod mill for grinding media parallel to the long steel bars, so can reduce the crush phenomenon.
In addition, the choice of the grading equipment, using a fine sieve and mill closed, pre-classification has some advantages. With a fine sieve for grading equipment. More stringent control of the mill product particle size, particle size can not drain away to avoid running rough" phenomenon. Followed by sieve screening efficiency, about 80-90%,spiral classifier, rake classifier is usually only 40-60% of the grade efficiency. This is likely to cause the fine-grained level re-qualified into the mill, resulting in the smash phenomenon.
2.the production process using closed-circuit grinding
The grinding process is the mineral particles to be ground to monomer separation should quickly from the mill discharged from. One hand, this can be avoided through the mill grinding media, on the other hand can make full role in the coarse mineral particles, so that energy can do useful work.
Production practice proves that the closed circuit grinding can effectively avoid the crush and "Coarse" phenomenon. It enables the grinding operation, uniform coarse granularity to ensure that qualified under the premise of narrow-level products, this is beneficial to the next sorting operation.
