Embodiment Construction

[0031] The present invention proposes a ball mill less-ball grinding method, which is applied in a ball mill that uses ball mill steel balls to pulverize materials. The method is as follows: figure 1 As shown, including the following steps:

[0032] Step 101: Select 9 kinds of ball mill steel balls with different ball diameters, namely 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, and 90 mm.

[0033] The above-mentioned ball mill steel balls are specially treated chromium-manganese tungsten grinding balls. Compared with ordinary ball mill steel balls, their hardness and wear resistance are greatly improved, creating conditions for the use of small balls (ball diameters less than 30 mm) in the ball mill As the number or surface area of ​​the small balls increases or increases significantly, the action point or area of ​​the grinding increases or increases, and the grinding efficiency is also greatly improved.

[0034] Step 102, adding the ball mill steel balls with differen...

Abstract

The invention discloses a fewer ball milling method for a ball mill, which is applied to a ball mill which uses steel mill balls to crush materials. The method comprises the following steps of: selecting 9 kinds of steel mill balls with different ball diameters; adding steel mill balls with different ball diameters into the ball mill with materials according to a preset proportion; starting the ball mill to ensure that the steel mill balls in the ball mill crush the materials. According to the fewer ball milling method for the ball mill, the steel balls in the steel tank of the ball mill are mixed reasonably according to a certain proportion in nine specifications with ball diameters from 20 to 90mm, so that the impact force can be intensified by big balls, and the grinding contact area can be increased by small balls; and the big balls and the small balls are cooperated one another in cascade, so that the grinding effect of the steel mill balls is sufficiently played, and the grinding efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of ball mill grinding, in particular to a ball mill less-ball grinding method. Background technique [0002] Ball mill is one of the high-fine grinding machines widely used in industrial production. It is the key equipment for crushing materials (such as coal, lime and other materials). Ball mills are suitable for grinding various ores and other materials, and are widely used in mineral processing, building materials and chemical industries. There are many types, such as horizontal ball mills, ball mill bearings, energy-saving ball mills, overflow ball mills, ceramic ball mills, lattice ball mills, etc. [0003] Ball mill steel balls are the medium for grinding materials by ball mill. The friction between the steel balls of the ball mill and the collision and friction between the steel balls of the ball mill and the material produces a stripping effect. The steel balls of the ball mill are important basic parts of...
