Abstract
The invention relates to a double-roller crusher, which includes a roller and a plurality of tooth plates. The roll includes a roller body, and the tooth plates are fixed on the surface of the roller body. The bottom is fixedly connected; the shape of the positioning column is a truncated cone, and the diameter of the upper bottom surface of the positioning column is larger than the diameter of the lower bottom surface of the positioning column; the surface of the roller body is provided with several tooth installation grooves along the axial direction of the roller body, and the teeth installation grooves The bottom is provided with several positioning holes for positioning the teeth along the radial direction of the roller body. The shape of the positioning holes is a truncated cone. The opening is arranged at the bottom of the tooth installation groove, and the bottom of the tooth installation groove is also provided with a plurality of connecting holes; the positioning column is fixedly installed in the positioning hole, and the fastening hole matches the connecting hole. The structure design of the invention is reasonable, firm, reliable in performance and longer in service life.
Description
technical field [0001] The invention relates to a double-roller crusher, which belongs to the field of crushers. Background technique [0002] The toothed rollers in the existing double-roll crusher have high maintenance costs and maintenance time due to wear and tear during long-term use. The production cycle of the toothed rollers is about 10 to 20 days. Therefore, a double-roll crusher The production cycle is about one month. However, once the toothed roller is worn out, the roller body needs to be replaced, which brings about a large economic loss. [0003] Chinese Patent No. 201410353652.3 discloses a toothed roller of a tooth-plugging crusher with an interlocking mechanism and a pressing and shearing blade, which includes a plurality of hollow roller bodies, and the outer circular surfaces of the plurality of hollow roller bodies are respectively provided with multiple rows of tooth shanks A plurality of roller teeth are respectively inserted into the multi-row tooth...
