The purpose of leaving the machining allowance on the workpiece is to remove the machining errors and surface defects left by the previous process, such as cold hard layer, pore, sand layer, oxidation layer, decarburization layer, surface crack, etc. Internal stress layer and surface roughness after cutting.
during the proposed 18 year life of the mine. The mill design was then made with consideration for the estimated hardness of each block in terms of both SAG and Ball milling with allowance for annual periods when the ore is harder to grind. Operating specifications were selected to achieve an optimum of capital and operating costs
Someone wrote around " According to my understanding, Mill Tolerance is the tolerance for variation in the thickness of pipe from nominal pipe thickness which is 12.5% according to B31.3 ". This is not correct. EN 13480, ASME B31.1 and B31.3 often address to pipe tolerance, but they normally don't define its value.
Grinding Mill Design. Morgardshammar started to design and deliver grinding mills in the beginning of the century. Today the mills are computer designed and manufactured in big plants with modern machinery. In order to keep manufacturing costs at a minimum level, Morgardshammar has a series of standard mill diameters up to and including 6.5 m.
Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. ... Pulverizer Wear Allowance: ...
SAG Mill Charge. Defining the charge weight and height for fully autogenous grinding mill requires allowance for the ore specific gravity (and its variations) and accounting for the water content and the fine ore which will fill the interstitial spaces between the large ore pieces.

The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
