Raymond mill ring analysis reasons of short service life

Many users complain that life is too short roller ring of Raymond mill recently, how long can not be broken, so that they produce an illusion, think manufacturers to find the most expensive products to win maximum profit, using less steel ring roller. As everyone knows, the Raymond mill is to produce products according to the mutual extrusion grinding roller and the grinding ring, so that the grinding roller and the grinding ring material is generally wear resistance material of high steel manganese. Due to the often other, so that the time of faster damage.
For example, the process of the ring of Raymond mill, which is made 50SiMn production of steel, high manganese steel is a type of steel wear-resistant, high manganese steel after quenching water can get plasticity and high resistance to shocks. High manganese steel has high wear resistance, though its hardness is HB210 only, but its yield point S is low, only 40% B, so it has high plasticity and toughness. High manganese steel under external pressure and impact load, has a large plastic deformation or serious work hardening phenomenon is severe, the steel reinforcement, hardness increased significantly, up to HB450 ~ 550, so there is a resistance to wear.
High pressure suspension roller mill Raymond h You, the pressure of the mobile hanger spring roll on securing a crushing plant 1000-1500 kg. After work began, ring around the pin, and the role of the spring pressure and the centrifugal force, near the ring rolling mill, Raymond mill when the material in the cavity, Raymond around the ring rolling mill of the blade spindle to shovel in the mill roll and grinding ring, the compacted powder with air circulation fan in the analysis of the machine, described fine powder at a rate of gas into the cyclone dust collector is completed, the larger particles fall to the magnetic grinding separation equipment new circulating air blower back to repeat the above process, it can enter purification precipitator bag type. To ensure a stable yield and fineness of raymond mill.
So the grinding ring after ring blank - .. Trimming and heat treatment and end of the program to avoid grinding the ring of wear for a shorter period of time.
