The pulp should have a volume of 185*25%=456m3 in the ball mill Then the minimum grinding time = 456/135=338min Note: When the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no over-grinding phenomenon This value is only for theoretical calculation

Starting from the 1970s, a new generation of mills appeared Vertical mills (see Figure 3) were common for solid fuel grinding, generally with spring-loaded rollers The principle of the new generation of vertical mill was to direct higher pressure from the grinding element to the material bed using hydraulic systems

Feed Rate Calculator When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined Materials have rated surface speeds for a given type of cutter The harder the material the slower the speed Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated
