Problems solved by technology

In the prior art, whether it is a disc-driven pulverizer or a roller (wheel)-driven pulverizer, its disc and roller (wheel) are limited by the following factors, such as small crushing ratio, fine particles in the pulverized product The grade content is low, and it is difficult to meet the particle size requirements of the ball mill discharge (for example, the -200 mesh particle size content in the discharge exceeds 20%), so it can only replace the fine crusher, but not the ball mill at the same time.
Due to its equipment characteristics, it is difficult to adapt to materials and ores with high moisture content, so it cannot process materials and ores in various mines and buildin

Embodiment Construction

[0064] Such as Figure 1-3 As shown, the unit type roller disc pulverizer of the present invention has an annular track 1, an annular flat car 2, an annular grinding disc 4, a roller 7, a hydraulic system 26 and a power unit 6.

[0065] The circular flat car 2 is arranged on the circular track 1, and the bottom of the circular flat car 2 is provided with wheels 3, and the wheels 3 are placed on the track 1. The top of the flat car 2 is embedded with an annular grinding disc 4 made of a wear-resistant flat liner 19 .

[0066] Image 6 and Figure 7 An alternative embodiment of the above-mentioned structure is shown, that is, a conventional annular plane bearing 20 or an annular plane bearing bush 21 can also be used to replace the frame of the annular flatbed vehicle 2, the wheels 3 and the annular track 1. When the annular plane bearing 20 is used, the annular mill plate 4 is placed directly on top of the annular plane bearing 20 . The annular plane bearing (20) used can be ...

Abstract

A unit-type roller-disk pulverizer is composed of an annular grinding disk made up by embedding a flat lining plate on the annular flat bed car on an annular track, an annular machine frame, a toothed ring linked via gear to power mechanism, and 2-10 grinding units on said annular grinding disk. Said grinding unit consists of 2-6 grinding rollers with hydraulic cylinder at its both ends, pulverized material layer controller, unloader, plate cleaner for grinding roller, and material collecting small scraper.

Description

technical field [0001] The invention relates to a crusher for ores and materials in various mines and building materials industries, especially a roller disc crusher; it is especially suitable for continuous and efficient crushing of ores and materials less than 70mm in size, and is very useful in large-scale enterprises such as mines and building materials industries. it works. Background technique [0002] Roller disc mills generally include two types of disc-driven and roller-driven, for example: the "roller disc crusher" described in ZL93215042.X and the "roller mill" described in US15034920. In the prior art, whether it is a disc-driven pulverizer or a roller (wheel)-driven pulverizer, its disc and roller (wheel) are limited by the following factors, such as small crushing ratio, fine particles in the pulverized product Grade content is low, and it is difficult to meet the particle size requirements of ball mill discharge (for example, -200 mesh particle size content i...
