Cylindrical Energy-saving Ball Mill applied for the Minerals Grinding

Cylindrical Energy-saving Ball Mill applied for the Minerals Grinding, Xinhai

Xinhai Cylindrical Energy Saving Ball Mill, a high efficiency and energy saving ball mill with rolling bearing, is one of energy saving mills developed by Xinhai. It is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding. Improved product has a lager capacity of Up to 160t/h, and it is easy to start and saves 20-30% energy.

Cylindrical energy saving grid ball mill consists of feeding part, discharging part, rotary part, transmission part (reducer, small gear, motors, electrical control) and other major parts. Hollow shaft is steel castings, and the liner is detachable. Rotary gear is processed by casting hobbing. The cylinder is lined wear-resistant liner plate with good resistance to wear. This machine works stably.

From the 3D demo video, Its working principle can be seen intuitively. The main part of this kind of ball mill is cylinder with small diameter and large length rotating slowly by the transmission device. The material is fed from the cylinder inlet and grinded by the impact of steel ball and ore and self-grinding. Due to the continuously feeding material, the pressure pushes material to the outlet and the grinded material is discharged from the cylinder outlet. In wet grinding, material is taken out; in dry grinding, the material is taken out by air. The grid installed in the outlet of mill is relied for forced discharge. Low pulp surface in cylinder reduces the ore over-grinding, and prevent the steel ball out. Under the same production conditions, production capacity of grid mill is larger than overflow mill’s. Both ends of the cylinder body adopt rolling bearing instead of the sliding bearing, which is more energy-saving.

Advantages of Xinhai Cylindrical Energy-saving Ball Mill are as follows:

1. Large double row self-aligning roller bearing with low friction force is used to replace sliding bearing, which is easy to start and saves 20-30% energy.

2. Cylindrical energy saving grid ball mill is lined grooved ring plate which increases the contact surface of ball and ore and strengthens the grinding.

3. Large ore outlet and large capacity

4. The mill with diameter below 2.1 meters adopts whole machine frame, which is convenient for civil construction and equipment installation.

5. Oil mist lubrication device guarantees the lubrication of all gears

Xinhai Cylindrical Energy Saving Ball Mill is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
