Dec 23, 2013· In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. 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.

Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
To match a ball mill size and its motor size, some math is . To match a ball mill size and its motor size, some math is required. The power requirement calculated above is the motor power that must be applied at the mill drive .
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. 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 particle-size measurement device and size-control cyclones.
Ball mill plays an essential role in the mineral processing production line. So, it is very important to improve the production capacity of ball mill for the users. The purpose of ball mill is to grind the materials to qualified particle size.
Calculate and Select Ball Mill Ball Size for Optimum Grinding. 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.
Jun 25, 2018· Mill effective diameter = 2.23 m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pre-grinding operation.
How to improve the grinding efficiency of the ball mill. The grinding efficiency of ball mill is low the treatment capacity is low the production energy consumption is high the product fineness is unstable and so on which are the problems that most concentrators will encounter How to effectively improve the grinding efficiency of ball mill is an important problem
Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties. . Therefore it is important to maintain ...
Five reasons for low grinding efficiency of ball mill ... The grinding efficiency of ball mill is influenced by many factors, mainly including:movement form, rotation rate, addition and size of steel ball, material level and use of grinding aid. These factors affect the efficiency of the ball mill to some extent. 1.
1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles.
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".
