In the process of crushing, the ore grain size change from large to small is not happening at the same time, but gradually. At each stage of crushing, there is always a part that meet the requirements of the fine particle produced.In the process of grinding, in order to timely tell qualified fine grained, prevent crushing, raise the productivity of mill, sizing equipment are needed to complete.Qualified particles from the graded overflow (sieve sieve product) to the selected operation, coarse grain returns mill grinding.Therefore, in the grinding classification plays an important role in operation.
The current in the basis of the classification of commonly used equipment are: spiral classifier, hydrocyclone and fine screen.
1.The spiral classifier. This classifier is according to the different sizes of particles sedimentation velocity difference in water medium to classification.Because of its simple structure, stable operation, easy to operate, is widely applied in the concentrator.Spiral classifier according to the position of screw in the sink and the overflow of the high score higher or lower weir, submerged weir.High weir type suitable for ceding the graded overflow is greater than 0.15 mm, is more suitable for the first period of grinding, and sinking type suitable for separated grade product is less than 0.15 mm, more than in the second period of grinding and grinding unit into a closed circuit.
2. Hydrocyclone. Hydrocyclone is the use of centrifugal force to accelerate the settlement of ore grain grading equipment, it requires pressure feed, so the power consumption is big, but cover an area of an area small, cheap, large quantity, high classification efficiency, can obtain the overflow of the fine products, more closed-circuit grinding classification of equipment used in the second paragraph. 3. The fine screen. Because of the spiral classifier and hydrocyclone is according to the ore particles in water medium velocity for different grade, so easy to produce useful minerals in the enrichment of grit, cause crushing of useful minerals.And fine screen is completely according to the geometry size of ore grain grading, almost not affected by the density and grade efficiency is high, so in recent years, the fine screen in grinding cycle of grading equipment is becoming more and more attention.
We all know that flotation machine and magnetic sepatator is important machines in ore beneficiation, while the classifier is also important in the whole beneficiation process, Henan Bailing provide the whole set beneficiation equipment, welcome to consult.
