Product features: 1, low pressure loss streamlined design, can achieve lower operating costs. Power consumption is about 20% lower than that of similar grades. 2. Product fineness: reliable product fineness can be quickly obtained by adjusting the speed of the grading wheel and the fan. 3. Stable classification efficiency: even if the feed amount is increased, the stability of the particle size distribution of the product can be maintained. 4, accurate particle size classification: according to the required beam point, to maintain a narrow slope of the particle size distribution. High product reproducibility: even if the product is often replaced, the same product can be quickly and stably reproduced. 6, applicable to a variety of different minerals
