The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur.

This is a method of analysis where liquid drains through a stack of sieves, after which the residue needs to be dried, either over a hot plate or in an oven. If the oven temperature is too high, the sieve cloth might become loose and the solder joint could be damaged, therefore maintaining the temperature below 149°C (300 °F) is recommended.

The water depends on pressure or gravity feed into from overflow, Then under the action of centrifugal force, the coarse and heavy granular materials are thrown towards the wall and rotated downward, and discharge together with the formed concentrated liquid. The smaller materials were discharged after rotating again.

Explanation of Sand Casting Process: Sand is to be rammed in Cope and Drag which are metal boxes and are to be placed one on the other. In the Cope box, the passages will be created with the help of the Sprue pin and the Riser pin whereas, in the Drag box, the casting cavity will be created by placing the pattern. As we have two patterns.

· Colloid mill works on the rotorstator principle. The equipment breaks down materials by forming dispersion of materials in a liquid. Shearing takes place in a narrow gap between a static cone (the stator) and a rapidly rotating cone (the rotor). To reduce wear, the rotor and stator are constructed using toughened steel or corundum. The rotor of a colloid mill can .
