Multiple Choice Questions on Mechanical Operations
2. Wear and tear in wet crushing is more than that in dry crushing of materials. 3. Size enlargement (opposite of size reduction) is not a mechanical operation. 4. A ''dust catcher'' is simply an enlargement in a pipeline which permits the solids to settle down due to reduction in velocity of the dust laden gas. Correct.

Ball Mill Critical Speed
A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula.

Ball Mills
3.6.1.1 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

Ball Mill
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

Vibration Mill: Components, Advantages and Disadvantages of using...
A vibration mill is a size reduction equipment that applies the process of continuous impaction in carrying out its size reduction function. The grinding container is made up of a tube that is held in a frame that is supported by means of springs which is filled to approximately 80% total volume with porcelain or stainless steel balls.
