In any crushing operation, the raw material flow rate and the reduction ratio (ratio of feed size to product size) have obvious influences on the wear of crushing equipment. However, the hardness and fracture toughness of the rocks being crushed are unavoidable parameters in allowing for .
Jan 07, 2015· Raw mills usually operate at 7274% critical speed and cement mills at 7476%. Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2**(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm. 7.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
For a quick into to High Speed Machining (HSM), try my CNC Chef video. There are many definitions for High Speed Machining (HSM). MMSOnline uses the tagline "Achieving high metal removal rates with quick milling passes" for the HSM zone on their very high tech definition of HSM is "Machining at the Resonant Frequency of the Machine," which goes to HSM techniques for ...
How to use: Choose a type of operation (drilling, reaming, boring, counterboring, face milling, slab milling/side milling, end milling, or turning), select your stock material, choose a material for the tool (highspeed steel or carbide), input the quantity of teeth for the tool and the diameter of the workpiece/cutter. Hit the "Calculate ...
The cost of the raw material per one piece is given by this formula: In the previous example, assuming 0,7 Euro per kg as the Material cost per kg, and density of steel 7,8 kg/dm3 we obtain: RAW MATERIAL COST = 7 * 5 * 0,01 * 7,8 * 0,7 = 1,91 Euro. This procedure has to be repeated with each of the raw materials entering the process.
