A set of experimental test work has been carried out in a continuous pilot ball mill of X 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.
Overflow VS Grate Discharge Ball or Mill Why . Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution discharge mills give a final product in an open circuit.
Grate ball mill can be divided intodry grate ball mill andwet grate ball mill. With characteristics of high production capacity, wind discharge, high efficiency, energysaving, high grinding efficiency and fine particles, a grate ball mill is used for grinding ores with coarse particles; a wet grate ball mill suitable for all kinds of ores in beneficiation, chemical industry, cement and
The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium ( steel balls, cylpeb, and pebbles) put in the shell,grated discharge ball grinding mill, [Chat Online] what is a grate discharge in a ball mill . Horizontal Grinding Mill Overflow Type, Gratedischarge Type Contact Supplier.
#0183;#32;Overflow verses grate discharge ball mills: an experimental investigation Overflow Discharge Ball Mill in Operation Mineral Processing Duration: 1:42. Himanshu Srivastav 24,642 views.
Gratedischarge Type The gratedischarge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 100 mesh. Compartment type
grate discharge ball mill for gold ore mini. overflow ball mill equipment wet ball mill for gold mining Overflow Type Ball Mill A ball mill with simple structure Production capacity 0 17170t/h Product Improvement Wet type overflow ball mill is lined with Xinhai wear resistant rubber sheet with excellent wear resistance long service life and convenient maintenance Live Chat Overflow VS Grate
Ideally, the discharge rate through a gratepulp lifter assembly should be equal to the discharge rate through at a given mill holdup. However, the results obtained have shown that conventional pulp lifter designs cause considerable restrictions to flow resulting in reduced flow capacity.
Grate Discharge Ball Mill For Dolomite High Output. Jan 01 Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150250 m In Figure 72 C the discharge opening is at the centre of the mill while the feed is from both ends of the mill.
Grate type ball mill: grate type ball mill in the discharging end is provided with a grid plate, which is composed of a plurality of fanshaped hole plate, thematerial upward, material along the lift plate from slipping through the conical block, and the right to the hollow shaft neck and discharge ball mill.
Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure 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
Conversion costs. The potential benefits of converting an overflow mill to a grate discharge will frequently far outweigh the downsides. In operations needing improved grinding circuit performance, the ability to fully utilise the available installed ball mill power will enable higher throughput, a finer grind, or a combination of the two, which will lead in turn to increased production and a
grate ball mill technology group. rotation of ball mill,is to use synchronous motor by coupling to make small gear rotate,and fixed on the cylindrical shell big gear to make cylinder fine materials output with slurry by out feed small holes on the board,out feed end slurry surface is lower than middle spindle neck slurry effluent face,lower than low level,forced discharge.
