• Motor power: 18.5kw
Structural features of 900x1800 ball mill
• Simple structure: The ball mill is usually composed of a cylinder, end cover, bearing, transmission device, and other parts, with a compact structure, easy to install and maintain.
• Easy to operate: The ball mill adopts an advanced electrical control system, which is easy to operate and easy to master.
• Strong adaptability: It has strong adaptability to materials and can grind materials of various hardnesses to meet the production needs of different industries.
Wearing parts of ball mill
1. The liner is the part of the
ball mill that is in direct contact with the material. It is used to protect the cylinder and assist the grinding process. Common materials include high manganese steel, manganese steel, wear-resistant steel, etc. The liner will wear out as the use time increases. When the liner wears to a certain extent (such as 65% wear or a 72mm long crack), it should be replaced.
2. Steel balls are the media used in the ball mill to impact and grind materials. Steel balls can be divided into cast steel balls and forged steel balls according to their production process. Cast steel balls are suitable for dry grinding operations, and forged steel balls are suitable for wet grinding operations. After long-term use, the diameter of the steel balls will gradually decrease due to wear, thereby affecting the grinding efficiency.
3. Large and small gears are important components of the ball mill transmission system. During long-term operation, the tooth surfaces of large and small gears will wear out. When the wear of the pinion tooth surface reaches 30% of its tooth thickness and the wear of the large gear tooth surface reaches 25% of its tooth thickness, the friction surface should be turned and continued to be used. When the wear reaches 50%, the gear parts need to be replaced.
4. The ring gear is a key component for transmitting power in the ball mill. The edge of the ring gear is easily deformed due to the twisting force of operation. When the deformation exceeds a certain standard (such as 0.75cm), the ring gear needs to be replaced.
5. The hollow shaft is an important component for supporting and transmitting torque in the ball mill. The surface of the hollow shaft is prone to grooves, scars, cracks, or deformation due to friction. When these phenomena occur, the hollow shaft should be replaced in time to avoid equipment failure.
