Structure and composition
|
The overflow ball mill is a type of ball mill that is currently the most commonly used mill in the concentrator. It is mainly composed of a cylinder, an end cover, a main bearing, a hollow journal, a transmission gear and a feeder. The overflow ball mill is mainly composed of a cylinder body, an end cover, a main bearing, a hollow journal, a transmission gear and a feeder. The overflow ball mill barrel is welded with a steel plate with a thickness of 15-36mm. A flange made of cast steel is welded to both ends of the barrel, and the end caps 2 and 3 are connected with the flange by bolts. It must be precision machined and matched because the hollow journal bearing the quality of the mill is welded to the end cap. There are 1-2 holes in the cylinder for maintenance and replacement of the liner. A liner 5 is placed inside the cylinder and the end cap. A hollow journal on the end cap is supported on the main bearing 4. The main bearing is usually a plain bearing, which has a large diameter but a short length. The bearing pads are cast from babbitt alloy and differ from conventional plain bearings in that only the lower half has bushings. The entire bearing is made of cast iron except that the bearing bush is cast with Papillon gold.

Performance characteristics
|
1. The transmission adopts rolling bearing instead of sliding bearing, the friction is greatly reduced, the starting is easy, and the energy saving is remarkable.
2. The taper design is adopted at the discharge end, which not only increases the volume, but also forces the material of the cone end and the ball of the ball mill to be classified. The closer to the outlet, the smaller the diameter of the steel ball increases the repeated grinding effect;
3. Grooved annular lining plate is used to increase the contact surface of the ball and the ore, strengthen the grinding effect, and improve the ore, reducing energy consumption.
4, the use of the overall frame, easy to civil construction (construction of a cement foundation) and equipment installation.

Working principle
| The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished Ball mill grinds material by rotating a cylinder with a steel grinding ball, causing the ball to fall back into the cylinder and onto the material to be grinded. The rotation speed is usually from 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation. If the circular speed of the mill is too high, it will start to act like a centrifuge, and the ball will not fall, but stay around the mill. The point at which a mill becomes a centrifuge is called the "critical speed," and ball mills typically operate at 65 to 75 percent of that critical speed. |
