Quartz sand color selecting machine is composed of feeding part, discharging part, turning part, transmission part (accelerating machine, small transmission gear, motor, electric control) and so on. Quartz sand grinding ball and ball mill lining adopt silica, high aluminum, rubber material, increase the incorporation of iron impurities in quartz stone grinding process, to protect the purity of quartz. The unique characteristics of quartz sand, quartz sand separator sales in the choice of color, purity, keep in quartz sand whiteness etc. at the same time, choose what type of drying machine is very important in the industrial drying machine, by: single cylinder, three cylinder, rotary and indirect ways, can achieve rapid drying of materials, to adjust the rotating speed of the speed control, through a variety of automation equipment, and has compact structure, automation, production and series of equipment for the processing of quartz sand standard dry use and maintenance. The whole production process, low production cost, high modernization program, fast drying speed, can carry out centralized control of feeding and discharging, the machine running, ensure the quality of the equipment, but also saves labor and reduces the production cost, is very economic.
