Fine crushers/Grinders Feed size: 5 to 2mm Product about 200 mesh e.g. attrition mills, tumbling mills (ball mills and rod mills) 5.
In such mills, attrition forces predominate but impacts also play a part in size reduction. They are classed as intermediate grinders and are more useful than ball mills for milling sticky materials. 43.6 Selection Criteria for Size-reduction Equipment
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
A truly size reduction equipment for crushing variety of material. Belt minerals or any other processed material. Mainly used in Rice Mill, Edible oil plants, Sugar mill etc. Its width is small and permits intermediate discharge of the material at several points are readily made dust-tight by jacketing the trough.
Pulok K. Mukherjee, in Quality Control and Evaluation of Herbal Drugs, 2019 6.2.8.1 Medicinal Leaves and Herbs. Size reduction in leaf-type materials should be done in such a manner that the sample does not contain any stem or stalk. The size reduction should be performed using a shredding mill, hammer mill, pin mill, fluted rollers, or grinders.
Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick''s constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E

Intermediate autogenous grinding can efficiently replace the rod mill and ball mill stage of a conventional grinding circuit. The need was shown for closed circuit operation of the last stage of crushing to control the top size of the mill feed. A reasonable rate ratio between media and total mill feed was established.

PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal balls. Run the ball mill for 30 minutes at a speed of 1 rpm. After 30 minutes take out rice powder from the ball mill.
BALL MILL Principle- Th ball mill work on the principle of impact between the rapidly moving ball & the powder materiel, both enclose in a hollow cylinder. At low speed the ball role over each other attrition will be predominant mode of action. Thus, in boll mill impact or attrition or both are responsible for size reduction.
