SU301168A1 - ROTARY CRUSHER - Google Patents

Description

The invention is intended for crushing of ore, non-metallic rocks and materials.

Known rotary crushers containing a frame, a rotor and a split housing, the upper part of which is mounted with the possibility of rolling on rollers on rails.

The purpose of the invention is to simplify the device and reduce its service time. This is achieved by the fact that the plane of the connector of the rolling-away part of the body is inclined towards the side of rolling away, and the rollers are made in the form of sector rollers.

In order to facilitate the moving away of the rolling part of the body, a lever is hinged on the back wall of the latter, the lower end of which rests on the groove made on the frame.

FIG. 1 shows schematically the proposed rotor crusher with the housing closed (a) and with the housing open (b); in fig. 2-rotary crusher in cross section; in fig. 3 levers for moving the body from a place in two projections.

The body of the rotary crusher consists of a fixed part — a bed / and a rolling part 2. Inside the case there is a rotor 3. The rolling part of the body and the bed have flange joints in two planes of LO and OM. The OB plane is tilted toward the haulage. The rollout part of the body has four rigidly fixed axles 4, on which sector rollers 5 are mounted, supported on horizontal rails 6, fixed on the frame. On

the rear wall of the rolling part of the axle 7 axis is a hinged lever 8 having a gripping rod 9 on the bottom and a handle 10 on the top 10. The gripping rod fits into the grooves 11 of the grips 12 fixed on the frame.

When the housing is closed, the lever 8 occupies a vertical position. To open the case and make the rotor accessible for convenient blending, it is sufficient to pull the lever knob. The resulting gripping rod

rests on the groove of the grip 12, and on the axis 7 a force is created that exceeds the force on the handle 10 by as many times as the shoulder of the handle is greater than the axis shoulder. This makes it possible to overcome the increased resistance at the moving of the body part 2 from the spot. At the same time, the lever 8 tilts, and the gripping rod extends from the gripping groove and does not prevent further rollback of part 2. Moreover, due to the inclined position of the flange connection along the plane of the OB, a gap between the flanges will slightly create a gap between the flanges, which facilitates further haulage Part 2 of the case. Running rollers in the form of sectors allows

There is no force required to roll back part 2 of the housing. When closing the housing, pushing its rolling part until the gripping rod 9 enters the groove 11. Further rolling of part 2 is carried out by pressing the handle 10. This facilitates tight fitting of the flanges, which are fastened by any known high-speed method {for example, hinged bolts or wedge connection).

Claims (2)

1. A rotor crusher comprising a bed, a rotor and a split housing, the upper part of which is mounted with the possibility of rolling back on rollers on rails, characterized in that, in order to simplify the design and shorten the service time, the plane of the connector of the rolling part of the hull is inclined towards the rolling away, and the rollers are made in the form of sector rollers. 2. A crusher according to claim 1, characterized in that, in order to facilitate the moving of the rolling-out part of the body, a lever is pivotally fixed on its rear wall, the lower end of which rests on the groove made on the frame.
