The main difference between raymond roller mill and high pressure suspension roller mill is feeding size, finished final size, yield, the appearance of main unit has not a large difference, it can be judged from the inside roller, compared with raymond roller mill, high pressure suspension roller mill has high pressure spring, because this high pressure spring of 1500 kg, high pressure suspension grinding mill has been greatly improved and perfected.
The smaller feeding size of raymond roller mill, the more stable the yield, and the processing capacity is higher, the range of high pressure suspension roller mill feeding size is larger than raymond roller mill. The finished final size of raymond roller mill is between 30 mesh and 325 mesh fineness, while the high pressure suspension roller mill range from 80 mesh to 425 mesh. Compared with raymond roller mill, high pressure suspension roller mill has some features: high finished final size and high pass sieve rate, because of the strong pressure of high pressure spring. The yield of high pressure suspension roller mill is higher than raymond roller mill.
High pressure suspension roller mill has the similar working principle as raymond roller mill, but the high pressure suspension roller mill’s grinding device is fixed with 1500kg pressure springs. When the machine works the grinding roller, which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of raymond roller mill given an identical condition and its capacity increase 20% to 30%. When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.
