Mo hardness is not greater than 9.3 and humidity below 6% in the milling and classification I. Working principle: YMP1250B type rod mill system consists of fine feeder, host, fans, classifier, powder cyclone, bag filter, electrical controls and piping system. Among them, the host from the upper and lower body, roller, rotary disc and the reducer. Work, will need to crush the material by the host side at the top of the quantitative electromagnetic vibrating feeder, evenly and continuously into the host, the rapid rotation of the disc by the centrifugal force will throw disc material within the wall, while hanging in the host The three top roller comes with power high-speed rotating around its own axis, the material being brought into the roller and the disc between the spring pressure applied in the roller under the effect of cutting and grinding roll. Meanwhile, the closed air circulation system, the resulting high pressure and large flow of air, and has been crushed into a powder mixture of high concentrations of air into the upper part of the classifier host, sorting. Not reach the fineness of the weight back on the grinding disc, with the air passing into the finished product is powder separator, fine powder and separated from the discharge port of air discharge is finished. II. Features: 1, milling pressure; roller hydraulic cylinder pressure, smooth, little vibration, low noise, single roller applied pressure up to 2500KG, and the grinding force according to the hardness of the material, easy to adjust the fineness. 2, the work roll grinding mill circle and not in direct contact between them there is always a material layer (gap), grinding roller circle and long life. 3, to achieve ultra-fine dry grinding: capable of processing 800 heads -1250 graded mesh powder, with high per unit of production III.
