Pipe Mill is widely used in building materials, metallurgy, mineral processing, power and chemical industry grinding cement and other materials. The pipe mill has the characteristics of large crushing ratio, large production capacity, strong adaptability to material and easy replacement of wear parts. The main components of pipe Mill are: cylinder, feeding department, unloading department, Tube Mill transmission department and so on.
Tube Mill is mainly composed of cylindrical cylinder, end cover, bearing and transmission big gear ring and other components, cylinder body loaded into the diameter of 25-150mm steel ball or steel rod, Tube Mill known as the Mill, the volume of the whole cylinder has a volume of 25%-50%. The ends of the cylinder are covered with a cap, and the end cap is connected with the flange of the end of the cylinder, the middle of the end cap is perforated, called the hollow axle neck, and the hollow axle neck is supported on the bearing, and the barrel body can rotate. A large gear ring is also fixed on the cylinder. In the drive system, the motor through the coupling, Tube Mill reducer and pinion drive large gear ring and cylinder, slowly rotating. When the cylinder body rotates, the grinding medium rises to a certain height with the wall, then falls or falls down in a parabola. As the end cover has a hollow axle neck, the material from the left side of the hollow axle neck to the cylinder, and gradually to the right diffusion movement, when the material moves from left to right, the rotating cylinder will bring the steel ball to a certain height and the material will be crushed, while a part of the steel ball in the cylinder in the discharge state of the material has a grinding effect, Tube Mill the entire movement process is also the material crushing process.
A pipe mill is provided with a lattice plate on the right end (discharging end), and the lattice plate is 7-20mm by a plurality of fan grate holes generally to 7-8mm is advisable, the material can pass through the grate hole into the space between the grid plate and the end cover, and then lift the material up to 2, lifting the material up, the lifting plate slipped through the cone block and right to the hollow axle neck, Tube Mill and then by the hollow axle neck out of the machine.
Another way is the wind-driven pipe mill used to discharge material, material from the feed mouth into the pipe mill, with the mill Rotary, grinding machine internal grinding (steel ball) to the material impact and grinding, material from the mill left (imports) gradually to the right side of the movement, in the course of the movement is the material crushing, grinding process. The outlet of the pipe mill is connected with the air duct, Tube Mill and the inlet of the separator and the fan are selected in the piping system. When the wind system is driving, the tube mill body is also in the low negative pressure operation. When the grinding material with the mill's rotation into a loose shape, and with the wind from the outlet into the pipeline system, from the separator to the coarse particles after the separation into the pipe mill imports, fine powder from the separator recovery, gas from the air blower into the atmosphere.
