Ball is from the cylinder, and out of the hollow shaft and the grinding material and some other level of constitutive Hubei small ball, cylinder for long cylinder, cylinder with grinding, cylinder for steel making small ball, with steel liner and cylinder fixation, usually steel grinding balls, according to different diameters and a certain percentage into the cylinder, grinding steel segment can also be used. Be selected according to the particle size of the abrasive material, the material from the mill feed end of the hollow shaft into the cylinder body, when the ball rotates the cylinder when grinding due to inertia and centrifugal force, the role of friction, so that it is attached to the cylinder liner was taken away by the barrel, when the time was taken to a certain height, because of its own gravity has been thrown down, falling like a projectile, like grinding the material to crush the cylinder body. Ball handling ability with the ball filling rate increases, increase the filling rate increases the chances of the ball crushing mill ore and ore autogenous grinding effect. Ball filling rate of 45% when the load is the maximum Jiangxi small ball mill, more than 45 percent increase over the filling rate of a significant decline in its load. This is mainly because with the increase of the filling rate of Henan small ball, throw the ball starting point is raised, the ball hit the red fall together near the point of acceleration and turning over to the center, while greatly reducing their moment together to become O negative, the ball (including mine) drop falling combined impact load torque required by large becomes 0 until turns driving force behind the barrel rotation (ie, over the center point of force, combined torque is negative). Raw materials through the hollow ball into the hollow cylinder journal to carry out grinding, cylindrical built with various diameters of grinding media (balls, steel bars or gravel, etc.). When the drum about a horizontal axis of rotation at a certain speed, mounted in the barrel of the medium and materials under the action of centrifugal force and frictional force, as the cylinder reaches a certain height, is greater than when the centrifugal force of its own gravity, then from the cylinder falling or rolling down the inner wall of the projectile, as a result of the impact and crushed ore. While during the rotation of the mill, grinding media sliding movement between each other to produce the raw material also the grinding effect. After grinding the material discharged through the hollow journal. Henan small ball, Ding Wang Machinery (certified), small ball by Wang Ding Machinery Co., Ltd., Henan Province.
