### PARTICLE SIZE REDUCTION TECHNIQUES

BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume. A fixed number of ball ...

### Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING

Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls. The size reduction is actually to make the too large to be used solid materials usable. It leads to an ...

### Effect of mill type on the size reduction and phase ...

The present work aims at exploring the size reduction of γ-Al 2 O 3 using three mill types; single ball mill, air jet mill and planetary ball mill. In a similar manner to previous studies ( Zhou and Snyder, 1991 , Knozinger and Ratnasamy, 1978 ), X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) have been used to characterise the milled powders.

### FM 306: SIZE REDUCTION AND SIEVING

FM 306: SIZE REDUCTION AND SIEVING OBJECTIVE •To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving. •To estimate the energy required for the grinding operation. •To analyze the results using the available theories. INTRODUCTION Size reduction is major unit operation in industries ...

### Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...

### SIZE REDUCTION AND SIZE SEPARATION

The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill. Speed of rotation of the cylinder: · At low speed the mass of balls will slide or roll over each other and only a negligible amount of size reduction will take place. · At high speeds, balls ...

### Size Reduction - Visual Encyclopedia of stone …

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher , also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device . As the disc rotates, the feed material is struck and crushed by descending ...

### Size Reduction of Groundnut Shell by Ball Mill …

Ball mill experiment: Initially the ground nut shell is crushed and then subjected to the ball mill for further size reduction. The ball mill consists of a hollow cylindrical body of 26.8 cm diameter made up of stainless steel is filled with steel balls of 76.2 mm diameter. The ball mill was rotated at 60 rpm (critical speed = 82.8 rpm). Average feed size of 3.2 mm of groundnut shell weighing ...

### Ball Mills - Mineral Processing & Metallurgy

Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel- Head Ball-Rod Mill, as this unit can carry a greater ball or rod charge and has potentially higher ...

### Ball Mills - an overview | ScienceDirect Topics

In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the bed thickness. Early issues with vertical mills, such as narrower PSD and modified cement hydration characteristics compared with ball mills ...
