Detailed Description

The following description of the embodiments will help the public to understand the present invention, but the specific embodiments given by the applicant should not be considered as limiting the technical solution of the present invention, and any changes in the definition of the components or technical features and/or in the form of the overall structure rather than substantial changes should be considered as the protection scope defined by the technical solution of the present invention.

Referring to fig. 1 to 4, the technical solution of the present invention is as follows:

a roller crusher comprises a box body 1, wherein an eccentric shaft 2 is installed in the box body 1, the eccentric shaft 2 is connected with a crushing roller sleeve 3 through a bearing, two ends of the eccentric shaft 2 penetrate through the box body 1 and are respectively and rotatably connected with the box body 1 through bearing seats 4, two ends of the eccentric shaft 2 are respectively connected with belt pulleys 5 through expansion sleeves, a jaw plate 6 matched with the crushing roller sleeve 3 is installed on the box body 1, the jaw plate 6 is of an arc-shaped structure, and the box body 1, the crushing roller sleeve 3 and the jaw plate 6 form an arc-shaped crushing chamber together; the arc-shaped crushing chamber can prevent the bar-shaped ores from being directly discharged from the crushing chamber without being crushed, so that the generation of bar-shaped materials is effectively reduced; the dynamic properties of the roller crusher and its constant and large eccentric travel give it particularly high crushing strength and high throughput; compared with the traditional crusher, the ton capacity installed power roller crusher is about 1/3 of a jaw crusher and about 1/2 of a gyratory crusher under the condition of consistent discharge size, which means that the power consumption of the roller crusher is obviously reduced compared with the traditional crusher under the condition of the same yield.

A swing shaft 61 is arranged on the jaw 6, the swing shaft 61 is arranged on the box body 1 through a bearing seat 4, a toggle plate 62 is also arranged on the jaw 6, and the jaw 6 is connected with an adjusting mechanism 7 through the toggle plate 62; the adjusting mechanism 7 can adjust the opening size of the jaw plate 6 and control the discharging granularity; at the same time, the jaw 6 is supported by the toggle plate 62, and when the load is excessive, the toggle plate 62 is broken, thereby protecting the jaw 6.

A screening chamber 8 is arranged on the upper end face of the box body 1, a material channel 9 is arranged above the crushing roller sleeve 3, the screening chamber 8 is communicated with the box body 1 through the material channel 9, a supporting plate is arranged on the side wall of the box body 1, a grate plate supporting rod is arranged on the material channel 9, a grate plate 10 is obliquely arranged on the material channel 9, the grate plate 10 is connected with the supporting plate through a fixed lug plate, materials fall into a crushing chamber through screening coarse materials of the grate plate 10 and are output from a material outlet 11 after being crushed, and fine materials are output from the material outlet 11 through a gap between the crushing roller sleeve 3 and the box body 1 on the side opposite to the crushing chamber; due to the existence of the grate plate 10, the materials can be pre-screened in advance, the processing capacity of the roller type crusher is improved, the material crushing efficiency of the roller type crusher is improved, the power consumption, the material compaction and the machine overload risk are reduced, and the abrasion of a crushing lining plate is reduced to the maximum extent; the compact structure of the roller crusher, the specially designed crusher structure and the integrated screening chamber make the installation height of the crusher extremely low, and the equipment height is 20-50% of that of other primary crushers (depending on the type of the crusher).
