作者: Himanshu SrivastavThe overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By combining it with a mechanical classifier or wet-processing cyclone, you are able to extensively use this type for grinding in closed circuit or for special applications such as

Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.

2020-08-02· A set of experimental test has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m (diameter X length) at different mill speeds, percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of discharge flow mechanism.

作者: International Minerals Engineering Congress2020-07-24· We recently converted a grate discharge type ball mill (size 5.7X8.6m) to an Overflow type. Before conversion, the ball level was 26%, and we were able to obtain a grind of 90%+ passing 75mic at a throughput of 350t/h. After conversion it’s a nightmare to

Ball mill could wet grind and dry grind many kinds of minerals and grindable material, according to different ore discharge methods, there are grid type and overflow type ball mill.1.Discharge port reasonable discharge port design, de-ironing separator. Live Chat

2016-09-01· The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.

Overflow type ball mill is equipped with slow transmission system. When starting up, run the slow transmission system slowly first, then automatically switch to the main motor driving. When the liner is changed, only need to start and stop the slow transmission system, which not only saves the energy consumption, but also reduces the impact on the ball mill and the net

Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls. Types of ball mill dry grinding ball mill and wet grinding ball mill; grate discharge ball

2018-05-14· CITICIC can produce cylinder diameter below 8m ball mills. Ball mill Ball Mills Model： Overflow Ball Mill：φ1.5x3.0~φ5.6x8.5m，Effective volume 7.5~194.3m3 Grate Ball Mill：φ1.2x2.4~φ4x14m，Effective volume 2.2~157m3 Capacity:5-500 tph

2020-07-31· Overflow discharge ball mill is designed with no sieve plate so that the ore pulp can be discharged directly without filtration. It is very simple in structure and convenient in maintenance. Though there is no sieve plate, the discharge pipe is cast with reverse threads, which makes that the large ores and balls are hard to discharge from the ball mill

2009-07-30· Overflow discharge Wet Figure 8.5 Effect of mill filling on power draft for ball mills. The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4
