Particle size of the feed: For a mill to operate satisfactorily, the feed should be of proper size. Moisture content : Presence of more than 5% moisture hinders the milling process and produces a sticky mass. B. Factors related to the nature of the finished product Particle size : Moderately coarse powders may be obtained from various impact mill.

The hammer mill design is very robust and is used in many appliions, from grain milling to heavy duty requirements such as rock crushing or waste grinding. Hammer mills are part of the impact mill family, which means that the milling effect is obtained thanks to the speed at which particles are impacted, here, by one or several rotors. 2.

Many feed mills pass all incoming ingredients through a grinder for several reasons: (a) clumps and large fragments are reduced in size, (b) some moisture is removed due to aeration, and (c) additives such as antioxidants may be blended. All of these improve the ease of handling ingredients and their storability.

Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.

· The main assumption in milling is that, because multiround cutting tools are used, high speed and light feeds should be used as far as possible. Following is the formula to determine feed of milling cutter in mm per minute F = f×n×N Where, F = Feed rate (mm/minute) f = Feed per tooth n = No of teeth on the milling cutter

Ball Mill Work Principle The material enters the first silo of the mill uniformly through the feeding hollow shaft. The silo has a stepped lining or corrugated lining, which contains various specifiions of steel balls. The rotation of the cylinder produces centrifugal force to bring the steel balls to a certain level.

The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones. The lower impact forces are due to a combination of both smaller ball masses and lower drop heights resulting from the use of smaller balls and smaller mill diameters, respectively.
