Problems solved by technology

[0010] However, in the open text of this patent, since the liquid reservoir is coaxial with the ball mill, it is difficult to realize the pulping process smoothly;
[0011] 2. It is not conducive to the replacement of ball mill lining stones, ball stones and other auxiliary operations;
[0012] 3. When feeding and discharging materials, the pressure must be reduced first, and the liquid in the liquid reservoir must be drained;
[0013] 4. High safety requirements and high cost
[0014] Also have the patent application that publication number is CN1179361 and also disclose a kind of energy-saving ball mill, it is by installing material tank in an airtight water storage tank, and the inner cavity of material tank rotating shaft is used as inlet and outlet, and connects suction machine to carry out abrasive material, Like the above-mentioned patent application of CN1053828, this type of grinding machine cannot be used in industries such as ceramics that require grinding out slurry because the shaft of the material tank is used as the inlet and outlet.

Embodiment Construction

[0041] The features of the present invention can be further understood through the detailed description of the preferred embodiments in conjunction with the accompanying drawings.

[0042] Such as figure 2 and 3 As shown, the barrel 2 and the inner liner 3 are installed on the support 5, and can be rotated around the support shaft 4 on the support 5 through the transmission of the transmission system. The transmission system includes a motor 12 fixed on the side of the open liquid pool 17 and The belt connecting the motor 12 and the barrel 2, the liquid pool 17 is injected with liquid through the liquid filling pipe 14, and the liquid can also be discharged out of the liquid pool 17 through the liquid discharge pipe 16. The liquid is selected according to the different materials to be ground and the required specific gravity of the liquid. In this embodiment, water is preferred, and of course lubricating oil or other liquids can also be selected. The support 5 is fixed in t...

Abstract

A floating-in-liquid ball grinding is composed of a material drum with material feeding and discharging openings and air inlet and outlet, driven system for driving said material drum, and open liquid pool containing liquid in which the part or all of material drum is floating. Its advantages are high grinding efficiency, low electric consumption and cost, and simple structure.

Description

technical field [0001] The invention relates to a grinding device, in particular to a ball mill which adopts a liquid floating type for grinding to improve the grinding efficiency and facilitate the entry and exit of abrasive materials. Background technique [0002] Ball mills are widely used in ceramics, building materials, cement, mining and other industries to grind materials. It is the main equipment that consumes electric energy. In the ceramic industry, the power consumption of ball mills accounts for 40% to 50% of the total production power consumption, which has a great impact on the manufacturing cost of products. [0003] In ceramic enterprises, large-tonnage ball mills are often used for grinding blanks, such as 14-ton ball mills, including ball mill self-weight and materials, water, ball stones, ball linings and other materials, with a total weight of about 100 tons. The power of the motor is 95KW, and the power consumed is mainly used to overcome the frictiona...
