Dec 21 2020 This ball mill is typically designed to grind mineral ores and other materials with different hardness and it is widely used in different fields such as ore dressing building material field chemical industry etc. Due to the difference of its slurry discharging method it is divided to two types grid type ball mill and overflow type ball mill. Compared with grid type ball mill overflow type ball mill can
Jun 24 2015 The cost of a ball mill conversion from overflow to grate discharge is fairly affordable at 65000 for a 13′ x 15′ mill. This is only for the discharge head grates and pulp filters rubber. A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.
Overflow Ball Mill Suitable for almost all applications where a ball mill is required. Simple and trouble-free grinding method. The discharge trunnion can be furnished with trommel screen. Grate Discharge Ball Mill This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill.
Introduction Overflow type ball mill is a kind of mineral processing ball mill its name comes from its ore discharge way overflow type ball mill ore discharge way is not forced ore discharge only when the pressure in the barrel body to a certain.
Introduction The 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 re-grinding in open circuit.
Jul 03 2012 The trunnion overflow mill is the simplest to operate and is used for most ball mill applications especially for fine grinding and regrinding. Energy consumption is said to be about 15 less than that of a grate discharge mill of the same size although the grinding efficiencies of the two mills
Secondary Mills The standard method for sizing secondary ball mills usually the overflow type in AGSAG circuits follows published mill supplier information with aspect ratios in the range 11.5 to 12.0 depending upon product sizing and pulp flow i.e. the highest expected circulating loads Morrell 2001.
Introduction Energy saving ball mill is new designed equipment for mineral materials secondary grinding after crushing.The processing capacity of new type design is increased by 15-20. Application It is suitable for grinding all kinds of ores widely applied in the industries of cement silicate products new building materials refractory materials fertilizer etc.
For overflow ball mills the charge should not exceed 45 of the mill volume . For grate discharge mills the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R i.e.
Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials no matter wet grinding or dry grinding. In our company this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore it can save energy by 10-20.
Efficient For Secondary Grinding The ball grinding mill is extremely efficient for secondary grinding after crushing.

The Copper Mountain ball mills are 7315 mm 24 feet in diameter and 12040 mm 39.5 feet long. They are overflow discharge ball mills with inside diameters of 7315 mm 24 feet and grinding lengths of 11887 mm 39 feet. Each Ball mill is also driven by two 8500 horsepower ABB motors. Figure 3 - The 24 x 39.5 ball mill
Working Principle Principle of overflow ball mill the main component is a cylinder with diameter and length at a reasonable proportion. Driven by the transmission device the cylinder rotates with the materials fed from the cylinder inlet and crushed by the falling impacts and autogenous grinding of the steel balls and ores in the cylinder.
Global Energy-Saving Overflow Ball Mill Market Overview. The Global Energy-Saving Overflow Ball Mill Market is growing at a faster pace with substantial growth rates over the last few years and is estimated that the market will grow significantly in the forecasted period i.e. 2020 to 2027.
The powder was transported to the wet energy-saving overflow ball mill for one stage grinding by the belt conveyor and the undersize pulp -3mm was pumped into the hydrocyclone for the first stage classification by the slurry pump. The underflow returned to the ball mill for regrinding forming the first stage closed-circuit grinding.
The 4.27 m x 12.94 m EGL secondary ball mill is fitted with a 4125 kW motor and operates in overflow configuration. Ball mill discharge slurry gravitates to the feed of the SAG mill discharge screen situated above the mill discharge hopper.
