Practical 1 : Ball Milling | TF Lab 1

23/12/2013· In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length ...

Ball Mills - Mineral Processing & Metallurgy

13/02/2017· Rod and Ball Mills not so much however as their size reduction actions are hidden in the tube (mill). As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its 3.5” x 16’ rods at one end while the smaller particles migrate towards the discharge end and get slightly abraded (as in a Ball Mill) on ...

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 ...

The Effect of Ball Size Diameter on Milling Performance

well as the size reduction of the mill charge. It was thus required that these mentioned operating parameters be optimized by experimentally determining the most appropriate ball diameter so as to obtain the desired energy. Experimental Procedure A laboratory size ball mill of diameter 30 cm was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively as shown in Figure 1. Quartz …

Calculate and Select Ball Mill Ball Size for Optimum Grinding

02/08/2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Size Reduction Equipments - The Chemical Engineering World

24/12/2020· In ball mills, we are using metal balls as grinding material. Here half of the shell is filled with balls and feed material is fed with it. Now, due to rotation of shell, the metal balls will be taken to top with shell wall and from there it will fall and cause attrition and impact and reduces the size of …

Effect of ball and feed particle size distribution on the ...

01/06/2018· This approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized. The same policy is employed for the make-up charge where adding different ball sizes is done in order to optimize the mill ...

Size reduction with Planetary Ball Mills

Mixer Mills Preliminary size reduction Assisting RETSCH Planetary Ball Mills are used for the pulverization of soft, fibrous, hard and brittle ma- terials. They achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can be as large as 10 mm. If the sample feed size is larger than this then the sample must first undergo preliminary size reduction ...

DE-11: Lesson 43. SIZE REDUCTION

In the ball mill both shearing and impact forces are utilized in the size reduction. The unit consists of a horizontal, slow speed-rotating cylinder containing a charge of steel balls or flint stones. As the cylinder rotates balls are lifted up the sides of the cylinder and drop on to the material being comminuted, which fills the void spaces between the balls. The balls also tumble over each ...
