Embodiment 1

[0031] Embodiment 1 and effect see Fig. 1.

[0032] When preparing a high-speed interlayer shear crusher with a nominal volume of 346ml, it should be designed according to the following

[0033] 1. Preparation of the main cylinder of the shearing crusher

[0034] a. First make a stainless steel cylinder with an inner diameter of φ70mm and a height of 90mm, with a wall thickness of 5mm, openings at both ends, welded with a stainless steel flange with a sealing groove, and form the main cylinder part 13.

[0035] b, upper and lower end caps (in Fig. 1, 12, 22) are made of stainless steel plates with a thickness of 8mm. A water-cooling sleeve is welded at the center of the upper and lower end covers to cool the bearings. The lower end of the upper end cover is fixed to the lower part of the center hole of the upper end cover by means of screw connection, and the shaft seal at the lower end is fixed above the lower bearing for protection. lower bearing.

Description

technical field [0001] The invention belongs to the technical field of powder material mechanical crushing equipment from micron level to nano level in powder engineering. In particular, it provides a nano-powder high-speed interlayer shear crusher, which is suitable for further refining or eliminating various powder aggregates and bridging aggregates formed by high-temperature processes for various micron-sized brittle powder materials. Background technique [0002] The crushing of powder materials occupies an indispensable position in many industrial sectors and industries. For thousands of years, human beings have used simple crushing tools to start processing powder materials and invented various crushing machines. So far , The processing equipment for these powder materials can be roughly divided into four categories: 1. Various coarse crushing equipment such as: crocodile crusher, pendulum crusher, roll crusher, stamping crusher, etc. The second is ball mills, such as...
