Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

The main differentiation factor between tube mill and ball mill is the. A. Length to diameter ratio. B. Size of the grinding media. C. Final product size. D. Operating speed.

The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.

Difference between wet and dry grinding 1. Difference in (ball mill) structure Dry grinding. A dry ball mill is equipped with a cylindrical rotating device and two bins, which can rotate by gears. The discharge port is straight. There are also air intake devices, dust exhaust pipes, and dust collectors. Wet grinding

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

The ball mills crushed 78 tons per day and, after classification, the coarser part of this, amounting to 38 tons, was ground to about 250 mesh in the tube mill. The pulp fed into the mill contained: coarser than 40 mesh, 20.5 per cent.; 40 to 60 mesh, 43.8 per cent.; 60 to 100 mesh, 28.1 per cent.; 100 to 150 mesh, 7'6 per cent.

12. Vertical grinding mill has expensive wear parts, but compare with ball mill's whole maintenance of mill, lifter, and classifier, it is stiller cheaper and simpler than ball mill.

10 Difference Between Bowl Mill And Ball Tube Mill · Difference Between Sag Mill vs Ball Mill mech4study. Today we will learn about difference between sag mill vs ball mill A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting This commutation is an.

Tube Mills. Tube mills are in principle to be considered as ball mills, the basic difference being that the length/diameter ratio is greater (3—5). They are commonly used for surface cleaning or scrubbing action and fine grinding in open circuit. Pebble Mills. In some cases it is suitable to use screened fractions of the material as grinding ...

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The pebble mill is the name associated with a mill in which the grinding bodies are natural pebbles or possibly ceramic bodies; the general proportions of the mill being as for a "ball mill". It will be noticed that the differentiation between ball mill and the tube mill arises only from the different length to diameter ratios involved, and ...
