Problems solved by technology

Generally, the gear rollers of the crusher are rotated at 60° between the upper stage and the lower stage, so that the shaft rotates at 30°, 90°, 150°, 210°, 270°, 330° for a long time. The six extreme points receive the greatest impact, resulting in uneven axial force, breaking the shaft, damaging the reducer, burning the motor, etc., which affect the service life of the equipment

Embodiment Construction

[0018] see figure 1 , 2 , 3. The names of the components are as follows: frame 1, main shaft 2, single tooth 3, gear roller 4, hammer head 5, bearing housing 6, drive mechanism 7, and speed reduction mechanism 8.

[0019] see figure 1 , 2 3. The single-roller crusher includes a frame 1 with a rotating main shaft 2 on the frame 1. Seven toothed rollers 4 are evenly arranged side by side on the main shaft 2, and three single teeth 3 are evenly distributed along the circumference of each toothed roller 4. , the angle between each single tooth 3 is 120 degrees, and an alloy hammer head 5 is fixed on the pointed side of each single tooth 3 . The main shaft 2 is supported on the bearing housings 6 mounted on both sides of the frame 1, and the main shaft 2 is driven by a driving mechanism 7 (electric motor) and a reduction mechanism 8. The toothed roller 4 starts from the transmission direction, and starts from the second toothed roller 4. Each toothed roller 4 is evenly offset...

Abstract

The invention relates to a crushing equipment for sintered cake in a steel plant, that is, a single-roller crusher. it Including the frame, there is a rotating main shaft on the frame, and a plurality of toothed rollers with single teeth are arranged on the main shaft, and a plurality of single teeth are evenly distributed along the circumference of the toothed rollers, and an alloy hammer head is fixed on the side of each single tooth tip , the main shaft is supported on the bearing seats installed on both sides of the frame, the main shaft is driven by the driving mechanism and the reduction mechanism, the toothed rollers start from the transmission direction, and each toothed roller is evenly offset from the previous toothed roller starting from the second toothed roller Installed at a certain angle; the offset angle is equal to the angle between two single teeth on the toothed roller divided by the number of toothed rollers. On the premise of ensuring the high temperature resistance and wear resistance of the equipment, more attention is paid to the research on the service life of the equipment. By changing the installation angle of the toothed rollers, the axial force is very uniform, and the difference between the axial force and the radial force is reduced. The phenomenon that the shaft breaks evenly improves the stress on the main shaft and the life of the main shaft, thereby improving the overall life of the equipment.

Description

[0001] technical field [0002] The invention relates to a crushing equipment for sintered cake in a steel plant, that is, a single-roller crusher. Background technique [0003] In the prior art, the single roll crusher is widely used in iron and steel, metallurgical mines and other industries, and is more suitable for crushing medium-hard coarse materials. Granularity of cooling requirements. During the 1950s, the sintering machine was matched with the HKM type and other crushers. It is an extrusion toothed roller crusher for general crushing of rocks. Its main disadvantages include low crushing efficiency, uneven particle size, and material leakage. After the 1980s, the crusher used for the sintering machine was changed to a shearing single-tooth crusher. The main feature is that the grating plate is placed at the bottom, the toothed roller is inserted into the grating plate, and the ore is sheared between the toothed roller and the grating plate. The crushing efficiency...
