Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] In the present invention, the side close to the middle part along the axial direction of the main shaft 21 is defined as the inner side, and the side of the middle part is defined as the outer side accordingly.

[0024] Such as figure 1 As shown, the present invention sequentially arranges connected upper cover 4, cylinder body 22 and base 13 from top to bottom, upper cover 4 is provided with a feed port 17 communicating with the inner cavity of cylinder body 22, and base 13 is provided with a communication cylinder The discharge port 28 of the inner cavity of the body 22. Such as image 3 As shown, a lower bearing housing 11 is provided in the base 13, and a lower bearing 24 and a thrust bearing 25 are installed in the lower bearing housing 11. The lower bearing 24 is located above the thrust bearing 25, and the lower end of...

Abstract

The invention discloses an industrial sand-making crusher and belongs to the field of crushing equipment. The industrial sand-making crusher comprises an upper cover, a cylindrical shell and a pedestal which are in successive connection from top to bottom, and is characterized in that the crusher also comprises a main shaft, the pedestal is provided with a lower bearing seat, and the upper cover is provided with an upper bearing seat; the lower end of the main shaft is installed in the lower bearing seat via a lower bearing, and the upper end of the main shaft is installed in the upper bearing seat via an upper aligning bearing; an upper bearing cover is installed on the upper bearing seat, and a lower bearing cover is installed on the lower bearing seat; the main shaft is provided with a belt pulley disposed above the upper bearing cover; the main shaft in the cylindrical shell is fixedly provided with two or more counterattack rotors along the shaft direction; each counterattack rotor is provided with two or more connection racks along the circumferential direction; and each connection rack is provided with a striking plate. The crusher is capable of enabling a stone material and the stone material, the stone material and the striking plates, and the stone material and a wear-resistant liner plate to generate repeated bump, enabling the granularity of the stone material to be obviously reduced and finally preparing multi-corner-angle circle granular machine-made sand, and helps to improve the industrial sand making efficiency.

Description

technical field [0001] The invention belongs to the field of crushing equipment, and in particular relates to an industrial sand making crusher. Background technique [0002] Natural sand and gravel are non-renewable resources in a short period of time. With the rapid development of my country's infrastructure construction, natural sand and gravel are almost exhausted, and the excavation of sand and gravel has caused devastating damage to resources and the environment. Due to flood control, environmental protection, resources and many other factors, many cities have banned the use of natural sand. Stone materials such as rocks and ores can be crushed into industrial sand to replace natural sand. [0003] At present, there is no shaped sand making machine to produce industrial sand, so the research and development of sand making machines has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] The technical probl...
