Feed Flow-Rate. This parameter is used in conjunction with the feed density and motor power to establish the grinding rate in kWh/mt. Flow rate should be as steady as possible. If the whole stream is feeding direct to the mill, surge tanks should be considered.
The ideal grinder necessary is determined by feed size, feed rate, operating conditions and desired product output for processing. Stedman offers two types of industrial hammer mill grinders that transform the consistency of soft and rough materials by using the pulverizing technique of a hammer mill grinder to produce a finished particle.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
Dec 15, 2016· In the transverse grinding process a wheel, substantially wider than the actual cross feed, distributes over its face the developed cutting force, thus permitting higher downfeed rates. The cross feed, which is used in traverse grinding only, is commonly selected to equal a specific part of the wheel width, such as 1/4 to 1/12.

A milling machine is basically used for shaping, routing, boring, and drilling metals and other solid materials. Generally there are two categories of the milling machine which include the vertical type and the horizontal type. In order to optimize the capacity of the milling machine, it is essential to identify the appropriate milling machine type for specific tasks.
