Description

Grader rotor structure of Ramon crusher

Technical Field

The utility model relates to a grader rotor field especially relates to a grader rotor structure of thunder covers rubbing crusher.

Background

The classifier rotor of the Raymon pulverizer is an important part for controlling the pulverizing fineness and quality of titanium dioxide, and the rotating speed of the rotor must be increased to improve the pulverizing fineness, but the yield can be reduced. The crushing fineness and quality of the titanium dioxide are guaranteed, the crushing yield is improved to the greatest extent, the rotor must be replaced when the rotor blades are abraded to a certain degree, the machine is stopped for about two days for maintenance, and the cost for maintaining and replacing parts is high.

Because the design angle of the rotor blade is vertical to the sealing surface of the rotor and has no corner, the impact force of titanium dioxide particles born by the blade is the largest, and the effect of screening the particle size after crushing is relatively poor.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a classifier rotor structure of a Raymond pulverizer, which can properly reduce the rotating speed of a classifier rotor by improving the angle of a device blade on the premise of ensuring the fineness and quality of pulverization, thereby ensuring that the pulverization yield is even slightly improved; the rotating speed of the rotor is reduced, the scouring abrasion born by the rotor blades is reduced, the service life of the rotor is prolonged, the maintenance cost of the equipment is reduced, and the shutdown loss of the equipment is avoided to a certain extent.

In order to solve the technical problem, the utility model provides a following technical scheme: a classifier rotor structure of a Ramon crusher comprises a base plate, wherein a rotary column is arranged in the middle of the base plate, a plurality of groups of blades are fixed on the outer side of the rotary column, each blade comprises a bottom plate and a top plate, and the top plate and the bottom plate are of an integral structure; the top plate is of an arc structure, and the radian of the top plate is greater than pi/4; the bottom plate is obliquely arranged at the top end compared with the chassis.

As a preferred technical scheme of the utility model, every group the blade is for revolving the post central line and incline forward the setting.

As an optimized technical proposal of the utility model, the size of the chassis is larger than the length of the blade.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is:

in the device, on the premise of ensuring the crushing fineness and quality, the rotating speed of the rotor of the classifier can be properly reduced by improving the angle of the blades of the device, so that the crushing yield can be ensured and even slightly improved; the rotating speed of the rotor is reduced, the scouring abrasion born by the rotor blades is reduced, the service life of the rotor is prolonged, the maintenance cost of the equipment is reduced, and the shutdown loss of the equipment is avoided to a certain extent.
