Cement Ore Processing Grinder 20mm Mining Ball Mill Machine 8t/H

Name Cement Ore Processing Grinder 20mm Mining Ball Mill Machine 8t/H
Function Cement Ore Processing
Feeding Size 20mm




Ball mill is the key milling equipment after materials has been crushed. It is
widely used in Cement, silicate, new
construction material, refractory material, ferrous metal and nonferrous Metal
as well as ceramics. It is widely applied to
grind ores in dry or wet process.
Working principle: The ball mill is horizontal cylindrical rotation device,
driven by brim gearwheel. There are two chambersand grid. Material goes into
the first chamber through the feeding inlet. Inside the First chamber, there
are stage liners and ripple liners as well as steel balls. The shell rotates So
as to generate electricity, and this force brings ball to a
certain height and then balls drop Down by gravity, the impact is the grinding
force to the material. After the primary
grinding, Materials go into the second chamber through segregate screen. In the
second chamber, there are Flat liners and steel ball, after the secondary
grinding, material is discharged from the Discharging. Then finished.

Ball Mill:
Ball Mill grinds material by rotating a cylinder with steel grinding balls,
causing the balls to fall back into the cylinder and onto the material to be
ground. The rotation is usually between 4 to 20 revolutions per minute,
depending upon the diameter of the mill. The larger the diameter, the slower
the rotation. If the peripheral speed of the mill is too great, it begins to
act like a centrifuge and the balls do not fall back, but stay on the perimeter
of the mill. The point where the mill becomes a centrifuge is called the
"Critical Speed", and ball mills usually operate at 65% to 75% of the critical
speed.
