Jun 19, a motor with around horse power is calculated needed for the designed task. now we much select a ball mill that will draw this power. the ball mill motor power requirement calculated above as hp is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. the following shows how the size or select the matching mill required to draw this power.
Mar 10, 3 wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of dry ball mill. 4 the grinding particle size is fine and uniform, and the wet ball milling can not only grind agglomerate into fine particles, but also mix the lean material and the plastic material.
May 08, grinding mill power scale-up. probably one of the most comprehensive experimental investigations of the power demands of the ball or tube mill is that carried out by one of the present authors, with a worker, rose and evans by use of small-scale models; the test apparatus being that shown in fig..
Mill is the energy consumption. the power supplied to the mill is used primarily to lift the load (medium and charge). additional power is required to keep the mill rotating. 8.1.3 power drawn by ball, semi-autogenous and autogenous mills a simplified picture of the mill load is shown in figure 8.3 ad this can be used to establish the essential.
Modern mills operate with load cells and mill optimizer's which synchronize the mill weight, power draw, ore feed and weight with density control. where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids.
Motor power: 18.5-480kw; applications: ... there are energy-saving ore ball mill, dry and wet ball mill, ... when the material moves from left to right, the barrel of the ore ball mill brings the steel ball to a certain height and falls to crush the material, and part of the steel ball has a grinding effect on the material in the state of the.
