The structure of wet ball mill is simple. The discharge port is horn-shaped. There is a screw device in it, which is convenient for discharging materials. 2. Difference in working principle Dry grinding. Dry grinding means that when the ore is ground into required particle size, the powder will be brought out from the dry ball mill by airflow ...
Answer: Should I use dry or wet milling? Milling is essentially an interrupted process, this will causes the temperature at the cutting edge to fluctuate between high and low temperatures (approximately 1000 ° C). 01 Impact of cutting fluid As the …
Grate ball mill ( grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate.
The mill was fitted with two exchangeable discharge end-plates, allowing for overflow or grate discharge operation. The dry ore entered the mill through a variable speed conveyor belt at a fixed rate of 1 kg/min (0.06 t/h).
Cleary [80] considered axial transport and grate discharge in a dry ball mill and showed that in the absence of air flow that this is a slow diffusion process. Cleary et al. [81] examined the ...
1. Overflow type: discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill: the ore is discharged through the grate plate.

1.Description Ball mill is the key re-crush eqipment after the crushing. Ball mill is widely used in cement, silicate products, new building materials, refractories, chemical fertilizer, black and non-ferrous metal ore-dressing, as well as the production industry of glass or ceramics, for carry though dry or wet grinding of a variety ores and other materials.
About the Ball/Rod Mill. Ball mills and rod mills are essential mining equipment for further size reduction of ore after the crushing stage. They are applicable to the comminution of dry or wet ores and other grindable materials in ferrous and non-ferrous metal processing plants, cement plants, refractory plants, fertilizer plants, and smelters.
Wet Milling has several advantages including easy discharging. Simply rotate the mill with the discharge grate point down and open the valve. Dry Milling has advantages including reduce reactivity and ease of handling the dry solids. With a few design changes, dry discharging is simple and contained.

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.
The discharge port of the dry ball mill is straight, It adopts grate plate type tailing to discharge, the discharge is even. The discharge port of the wet ball mill is a horn type, with a built-in ...
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.
As a general rule: 1. For over-flow ball mills the charge should not exceed 45% of the mill volume, 2. For grate discharge mills the charge should occupy about 50% of the mill volume. 3.3 Ball Size at Initial Ball Charge. Ball sizes commercially available for charging in grinding mills range from 10 to 150 mm.
The discharge end of a Grate Discharge Ball Mill is fitted with grate sections approximately 3½" thick, made of special heat treated alloy steel developed for this particular application. The grate sections have tapered openings between ¼" and 7/8″ dependent upon the specific grinding application.
This model structure is proposed for multi-compartment ball mills for the calculation of breakage (r) and discharge rate (d) functions in different segments of the mill using the experimentally measured mill inside size distributions (p 1 and p 2) and calculated mill feed and discharge size distributions (p 3), in addition to segment hold-up (s 1, s 2, s 3 and s 4).
