Gold Mining Ball Mill Grinding Machine Overflow Ball Mill On Sale
Product introduction:
As the cylinder rotates and the grinding media moves, the crushed
ore and other materials gradually spread to the right, and finally
overflow from the hollow shaft neck on the right. Ball mills are
widely used in the production industries of black and non-ferrous
metal beneficiation, cement, refractory materials, silicate
products,glass and ceramics, etc.,to grind various ores and other
grindable materials in dry or wet manner. Ball mill use steel balls
or other grinding media inside grind materials fine powder or fine
particles through rotation of cylinder and the friction and
collision of the materials.
Ball mill loading:
The main function of steel ball in the ball mill is to impact and
crush the material, and it also plays a certain grinding role. The
quality of the crushing effect directly affects the grinding
efficiency and ultimately affects the output of the ball mill.
Whether the crushing requirements can be met depends on whether the
grading of the steel balls is reasonable, mainly including the size
of the steel balls, the number of ball diameters, and the
proportion of balls of various specifications.
The steel balls large enough impact force so that the ball mill
steel ball enough energy crush granular materials,directly related
to the maximum ball diameter of the steel balls. The steel balls
must have enough impact times on the material, which is related to
the steel ball filling rate and the average ball diameter. When the
loading amount is certain, on the premise of ensuring sufficient
impact force, try to reduce the diameter of the grinding body and
increase the number of steel balls to increase the number of
impacts on the material to improve the crushing efficiency.material
has enough residence time in the mill to ensure that the material
is fully crushed,requires the steel balls to have a certain ability
to control material flow rate.
