Analysis of ultrafine vertical roller mill structure

Our R & D vertical mill production is the leader in the industry of milling machine, the reason can be user so loved, sales volume also can be so good, because each structure it played a huge role, as the saying goes, unity is strength, every structure of  ultrafine vertical roller mill in output, condensation a mighty force, let the vertical mill glittering in the mill on the market.

Structure of  vertical milling machine : separator, upper and lower casing, grinding disc device and a transmission arm, a grinding roll device, transmission device, hydraulic station, dilute oil station. Each component of complement each other, play a decisive role. Like the human body each organ as complementary to sustain life, vertical milling machine the structure also allowed him to operate effectively.

Separator vertical mill, one of the core is provided with a radial blade rotor, rotor shaft comprises 2 self-aligning bearing support is fixed, the driving device for variable frequency motor + reducer vertical frequency converter control. And the inner wall of the lining plate separator with liner wear, can be replaced after.

The upper and lower shell interaction. The upper casing is a straight cylinder structure, on both sides of the door roller mill, the installation and maintenance of the import; was feeding port, the access door, above all for the seal structure. In the upper part of the cylinder part and the shell together constitute the milling chamber, the wind ring makes the circulating air inlet in relatively evenly through the grinding disc rim raised milled dust; both sides of the sliding bearing seat fixedly supporting roll grinding device; 2 mechanical caging device and the grinding roller device of rocker arm spacing bolts are used together to control the grinding roller the sleeve of the roller and the grinding disc liner clearance between the plates; lower discharge pipe for discharging the thick material bed edge drop.

Disc device and a transmission arm action is this: disc seat is provided with 8 blocks to the cylindrical positioning pin pressure ring fixed sector lining plate, is arranged outside the barrier material ring to control the thickness of the material bed grinding disc; disc seat through bolts, a cylindrical pin and thrust plate connected with the speed reducer, speed reducer to rotate; the 2 scraping frame used to pay thick material bed edge falling blew the discharging port.

Composed of a rocker, a roller core and sleeve of the roller, self-aligning bearing and a pressure ring; the arm and the rocker arm to the thrust of hydraulic cylinder is transferred to the roller shaft; one end of roller shaft is arranged in the rocker arm, the other end is provided with 2 sets of aligning bearings, sleeve roller core; the roller sleeve for tire shape,body is crushed, the frictional force under the action of grinding disc with rotation motion;pressure ring will roll sleeve is fixed on the roll core.

The transmission device is composed of a motor, a diaphragm type coupling, planetary gear reducer; planetary gear reducer and the transmission torque and the vertical upward thrust. Dilute oil station is separately to the planetary gear reducer oil, lubricating and cooling effect. Hydraulic station through the cylinder to milling side pressure, pulls out the grinding roller repair.
