Gold extraction

Ball Mill Ball mills can operate in either wet or dry conditions They are advantageous because they can achieve a very fine particle product size (refer to Table 1) Generally ball mills are utilized after an initial material crushing or grinding has occurred Thus a disadvantage of the ball mill is that the feed size must already be small Table 2 outlines some typical ball diameters found in ball mills dependent on the

Control of a Ball and Beam System

The ball and beam system can usually be found in most university control labs since it is relatively easy to build model and control theoretically The system includes a ball a beam a motor and several sensors The basic idea is to use the torque generated from motor to the control the position of the ball on the beam The ball rolls on the beam freely By employing linear sensing

Bearing Selection

When ball and roller bearings within the same dimension series are considered the roller bearings have a larger load capacity and are also capable of withstanding greater vibration and shock loads (3) Rotational speed The allowable speed of a bearing will differ depending upon bearing type size tolerances cage type load lubricating conditions and cooling conditions The allowable
