Ball Mill Machine Manufacturers Tell You the Working Principle of Ball Mill Machine

01The main composition of the ball mill machine

The basic composition of the ball mill machine includes a cylindrical barrel, end cover, bearing and transmission ring, etc. The barrel is mounted on a large bearing and placed horizontally. The cylinder body is equipped with the unquantified steel ball or steel rod (25mm-150mm of large steel ball), which accounts for 25%-50% of the effective volume of the whole cylinder body.

02Motion state of ball mill machine

In the grinding process of the ball mill machine, the rotation speed of the barrel generally operates from high to low, which can be divided into three motion states: release state, drop state and turnover state.

• Release state

The release state is generated when the ball mill machine is running at a low speed. At this time, the material is crushed and ground mainly depends on the mutual sliding of the medium itself.

• Drop state

The dropping state is produced when the ball mill machine is running at a high speed. At this time, the grinding process of the ball mill machine is completed by the impact power, followed by grinding operation.

• Turnover state

Turnover state, also known as the centrifugal state, is the state of motion when the speed of the ball mill barrel increases to a certain limit value (critical speed) (in general, the ball mill machine does not work under this state). At this point, all media will rotate with the cylinder rotation and will not fall. There is no grinding action between the material and medium when the ball mill machine is in a centrifugal state.

03Working principle of ball mill machine

The working principle of the ball mill machine is also the movement rule of the ball mill machine. The ball mill machine is driven by the motor to rotate, so as to realize the operation between the material in the barrel of the ball mill machine and the steel ball. When the medium inside the cylinder is brought to a certain height with the rotation of the ball mill machine, the medium will fall due to its own weight. At this time, the medium will be violently impacted by the steel ball inside the cylinder, over and over again, and finally the mineral grinding is completed.

The qualified materials will be pushed continuously along with the feed, sent to the outlet, and overflow automatically, and then enter the next link.
