Cement ball mill is mainly used in the cement plant finished and raw materials grinding, but also for metallurgy, chemical, power, etc.

Industrial and mining enterprises grinding a variety of ore and other grinding materials. Can be used for open grinding, but also for the composition of the circulation with the powder ring grinding. Cement mill has a strong adaptability to the material, can continue to produce, broken than large, easy to speed grinding products, such as the fineness of the characteristics. Cement ball mill can be dry production can also be wet production, can also be grinding and drying at the same time operations.

Working principle of ball mill:

Material from the feed device by the feed hollow shaft screw evenly into the first warehouse, the warehouse has a ladder liner or corrugated liner, built-in different specifications of the ball, the cylinder rotation to produce centrifugal force to a certain height after the ball Falling, the material has a heavy blow and grinding effect. Material in the first warehouse to reach rough grinding, the single compartment through the plate into the second warehouse, the warehouse is set with a flat liner, there are steel balls, the material further grinding. The powder is discharged through the discharge grate to complete the grinding operation.


Ball mill structure:

The ball mill consists of six parts: the feeding device, the supporting device, the rotating part, the discharging device, the transmission and the lubrication and cooling device.

Ball mill Features:

  • 1. ordinary cement ball mill: ordinary cement ball mill for most of the ring flow grinding system, which is characterized by high grinding efficiency, mill production, power consumption, especially when the grinding slag cement, the performance is more prominent. General mill production can be increased by 15-20%, power consumption reduced by about 10%, in addition, the finished product temperature can be reduced by 20-40 ℃, product fineness is also easy to adjust.
  • 2. high-fine high-yield cement ball mill: high-precision high-yield cement ball mill is mainly used for open-flow grinding system. Which is characterized by simple system equipment and process flow, investment in the province, the plant covers an area of ​​less; in the mill structure on the use of advanced internal powder special compartment device, fine grinding cabinet to increase the activation device, grinding tail with a special grate Plate, to minimize the grinding chamber grinding medium size, greatly improve the grinding efficiency, to achieve high yield, low energy consumption purposes.


New Ball Mill Technology Breakthrough

The new ball mill equipment from the raw material into the point of view, double-warehouse ball mill raw material through the hollow journal does not directly into the cylinder inside the grinding ball medium, so that when the cylinder around the horizontal axis to a certain speed of rotation when the dishes start further Sorting effect. The effect of this sorting is mainly manifested in the fact that large pieces of material fall into the crushing chamber and the small pieces of material enter the grinding chamber through the conveyor. In this way, when their own gravity is greater than the centrifugal force, they are from the inner wall of the cylinder sputtering or rolling down, resulting in the impact on the liner will be different according to the different needs of the different room for the broken work.


By further optimizing the grinding chamber feedback device of the ball mill equipment, it can be seen that the necessary feedback can be easily captured by the "ear" without further transformation. On the ball mill sub-warehouse played a certain role in supporting. The ball mill after the cartridge is tested and can be used to suppress the consumption of ball mill supplies such as steel balls and liners. In the statistical comparison, you can find the use of the first warehouse of the broken set, you can change the first warehouse conditions, and make the first warehouse will be compared with the traditional crushing stage has obvious advantages. It is possible to shorten the time interval into the second bin grinding. In addition, after the sub-warehouse in the role of driving the motor, the ball mill can play two different effects of mineral processing, one is broken effect, the other is grinding effect. Using the inertial force of the large equipment to break, which is also one of the unique properties of the sub-tank mill. Comprehensive comparison, sub-type ball mill can save electricity than the traditional ball mill to 40% -50% between. Through the power distribution circuit of the supercharging effect, start time consumption than before reduced by 3-5 minutes. While the overall production and grinding efficiency than the previous increase of 35% -45%.

SBM machinery with sophisticated machinery and equipment, superb processing capacity and fine management practices, advanced process design, quality assurance system sound, pre-sale, sale, after-sales service and thoughtful. Adhering to the customer first, quality first, win-win cooperation, integrity is the purpose of the gold, customer value orientation as the company's core values, Yuanyuguangda customers sincere cooperation in the tide of economic globalization, split the wind, Create tomorrow.
