Problems solved by technology

[0003] However, the existing roller sleeves are generally steel castings, and the roller teeth are easily impacted during use, causing chipping and wear, and the wear resistance of the roller teeth and the roller sleeves is not synchronized, and the service life is only 3 to 5 months. The final roller sleeve can only be removed, which is not easy to maintain, which greatly reduces the service life of the roller crusher

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 and figure 2 As shown in the figure, a wear-resistant toothed roller sleeve of a roller crusher is composed of a roller core (1) and a roller sleeve (2) from the inside to the outside. The roller sleeve (2) is set on the roller core (1), and Stay on-axis. A plurality of rings of roller teeth (7) are radially distributed on the outer peripheral surface of the roller sleeve (2), and each ring of roller teeth (7) is equidistantly arranged.

[0022] The roller core (1) includes a cylinder ring, which is used to be installed on the rotating shaft and kept relatively fixed; the outer surface of the cylinder ring is provided with three elongated bosses (3) in the axial direction , the distance between...

Abstract

The invention discloses a wear-resistant tooth roll shell for a roll crusher, which comprises a roll core and a roll shell. The roll shell sleeves the outer peripheral surface of the roll core and isfixed by a fastener; a plurality of rows of roll teeth are formed on the outer peripheral surface of the roll shell in the circumferential direction; in the circumferential direction, opposite tooth profiles on two adjacent roll teeth are covered with a first wear-resistant layer; in a radial direction, opposite tooth profiles on two adjacent roll teeth are covered with a second wear-resistant layer; the outer surface of the roll shell is covered with a first impact-resistant layer; sealing flanges are arranged on both left and right end faces of the roll shell. The wear-resistant tooth roll shell for the roll crusher, which is provided by the invention, has the advantages of long service life, easiness for processing and easiness for repair.

Description

technical field [0001] The invention relates to the technical field of crusher equipment, in particular to a wear-resistant toothed roller sleeve of a roller crusher. Background technique [0002] Wear resistance and anti-wear technology are always unavoidable problems in the efficient operation of industrial equipment. The wide application of various high-performance wear-resistant materials and technologies is the key to the large-scale promotion and application of new dry process cement production and various energy-saving and high-efficiency grinding technologies. an important material basis. In a modern cement production line, different types of wear-resistant materials are widely used in roller presses, grate coolers, and crushers to ensure the continuous and efficient operation of the entire process. The performance and service life of these wear-resistant materials are also directly related to the normal production and economic benefits of cement enterprises. The c...
