Problems solved by technology
The toothed roller crusher has better control over the output particle size, less over-crushing, and larger output, but the crushing ratio is small. Although the other types of crushers have large crushing ratios, the control of the output particle size is not good, and the over-breaking is large. material, easy to block, low output
In addition, from the principle of crushing, it mainly relies on extrusion and percussion crushing, which consumes a lot of energy.

Embodiment Construction
[0012] A side crushing and screening crusher with a large crushing ratio, several toothed discs 1 are installed on a single or two toothed roller shafts 2, if the toothed discs 1 are installed on two toothed roller shafts 2, the toothed discs 1 are arranged alternately , driven by one or two transmission systems 4 to rotate together. The number of disks 1 is related to the processing capacity, the diameter of the toothed disk 1, the rotational speed, the distribution density of the crushing teeth 3, etc. The larger the processing capacity, the more the number of toothed disks 1 needed; The higher the distribution density of the teeth 3 is, the less the number of tooth discs 1 is required. Removable and replaceable crushing teeth 3 are installed on both sides of each toothed disc 1. The size, shape, quantity and arrangement of the crushing teeth 3 are related to the properties of the material 7 to be crushed and the size of the output particle size. A crushing plate 6 is arran...

The invention relates to a large-crushing-ratio side crushing sieving crusher. The large-crushing-ratio side crushing sieving crusher is used for large-crushing-ratio crushing. According to the scheme, multiple gear discs are installed on one or two gear roll shafts, and the gear discs are arranged in a staggered mode and driven by one or two drive systems to rotate together. Detachable crushing teeth are installed on the two sides of each gear disc, crushing plates are arranged adjacent to the sides of each gear disc, and wedge-shaped crushing cavities are formed by the crushing plates and the side faces of the gear discs. After materials enter the wedge-shaped crushing cavities, the materials are gradually crushed under the effects of splitting, stretching, extrusion and the like of the rotating crushing teeth, and finally are forcedly discharged from the bottoms of the wedge-shaped crushing cavities through the rotating crushing teeth. In order to prevent the materials from leaking from a non-crushing working area, cover plates are arranged on the gear discs, sieve holes can be opened through the cover plates, the materials which do not need to be crushed directly leak from the sieve holes, and the materials needing to be crushed slide into the wedge-shaped crushing cavities along the cover plates to be crushed. Large-crushing-ratio crushing of the materials can be achieved, the discharging granularity can be controlled, forced discharge is achieved, excessive crushing is reduced, and power consumption is reduced.
Description
Technical field [0001] The invention relates to a side crushing and screening crusher with a large crushing ratio, which is mainly used for crushing materials with a large crushing ratio, forcing discharge, improving productivity, reducing over-crushing, and reducing power consumption. Background technique [0002] The crushers currently on the market mainly include toothed roller crushers, jaw crushers, cone crushers, and ring hammer crushers. The toothed roller crusher has better control over the output particle size, less over-crushing, and larger output, but the crushing ratio is small. Although the other types of crushers have large crushing ratios, the control of the output particle size is not good, and the over-breaking is large. The material is easy to block and the output is low. In addition, from the principle of crushing, it mainly relies on extrusion and percussion crushing, which consumes a lot of energy. Contents of the invention [0003] In order to solve...
