The grate-discharge 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.
Overflow Type Ball Mill Features: 1. The jack-up device of wet grate ball mill makes maintenance easy. 2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill. 3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance. 4.
Grate and Overflow Ball Mill-Jiangsu Zhongbo Machinery. The basic types of commonly used ball mill in the production are grate mill, … Grate type ball mill belongs to low level forced discharge type grinding equipment.
The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.It is a high technological enterprise that integrated …

Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of design and production of finer product.

Ball Mill Discharge Grate Vs Overflow. How a Grate Discharge Ball Mill Works A grate assembly at the discharge en d of the mill permits retention of a higher ball charge up to 50 than is possible in an overflow mill which has a practical limit of around 40.
The overflow mill is better if the material needs to be ground to the fine products (150-200 mesh). 2. According to the production capacity. The grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of the overflow type ball mill. The overflow ball mill discharges the ore by the ...
The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."
the mill based on the charge and application. No auxiliary drive is required to perform maintenance, which is done quickly with minimal heavy lifting due to the simple removal of the grate or discharge head to access the mill internals. Sepro Mill shells are manufactured in one piece to high quality standards and are thermally stress

Kunming Ciba Mining Machinery Co., Ltd. is involved in designing and manufacturing wet-grinding grate-discharge and overflow-discharge ball mills, and wet-grinding overflow-discharge rod mill which own multiple patents. The advantages of such equipment includes properly designed feed opening, cylindrical section made of high-strength steel ...
This overflow ball mill is typically designed to grinding ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, and that. Because of its slurry discharging method, it is named as overflow ball mill. When compared with grid ball mill, it can ...

Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills are used when the grinding energy shall be concentrated to the coarse particles without production of slimes.
Overflow Type Ball Mill The overflow ball mill has relatively simple structure--the advantage of no grate fence, high fineness in grinding, and less ball loading etc. Widely used in the second segment or place of comparably finer product. When the motor drive the pinion and the big gear rotating, the material will get into the cylinder from the left end through the hollow shaft neck …
Energy Saving Mining Ball Mill. The Energy Saving Mining Ball Mill is a new developed mill by our factory. It adopts the center transmission, the rolling bearing support, side discharging, overflow discharging and grate discharging. It is suitable for the grinding of the metal mines of less than 25mm feeding and 200mesh discharging. Read more
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. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.

How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.
Ball mill is widely suitable for ore dressing, chemical, coal, cement, and refractory to operate fine grinding. ball mill can specify ball mill as wet grate rolling bearing energy ball mill, overflow ball mill, grate ball mill, wet rod mill, wet cone ball mill. the first kind of ball mill is the most popular ones in our gold mining plant.
Grate discharge will absorb 15 to 20% power than an Overflow mill for the same ball filling degree. To achieve your grind, you should increase your ball filling degree to reach the same specific energy as you had in grate discharge.
Gross power calculator general depends on whether the mill is an overflow or a grate discharge machine in all cases ag and sag mills 2 are grate discharge and ball mills are mostly overflow a few however are grate discharge in overflow,Ball Mill Overflow Grate Power.
