Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0020] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] like figure 1 As shown, a four-roller crusher includes a feed port 1, a crushing barrel 2, a base 14, and a drive motor 13 is fixed at both ends of the base 14, and a crushing barrel 2 is arranged between the two motors, and The crushing stone barrel 2 is fixedly installed on the base 14. The upper end of the crushing stone barrel 2 is provided with a feed inlet 1, and the lower end is provided with a funnel-shaped feed opening 12. There are two through grooves respectively, and the hinge 9 passe...

Abstract

The invention discloses a four-roll crusher which comprises a feeding opening, a stone crushing barrel and a base. The two ends of the base are each fixedly provided with a motor, the stone crushing barrel is arranged between the two motors and fixedly mounted on the base, a feeding opening is formed in the upper end of the stone crushing barrel, a funnel-shaped collecting opening is formed in the lower end of the stone crushing barrel, two through grooves are formed in the two ends of the outer wall on the upper portion of the stone crushing barrel respectively, and two through grooves are formed in the two ends of the outer wall of the lower portion of the stone crushing barrel respectively. Hinges penetrate through the through grooves, the hinges on the outer wall of the stone crushing barrel are fixed through locating roll shafts, the locating roll shafts are fixedly mounted on the outer wall of the stone crushing barrel, and four rollers are arranged on the upper middle portion in the stone crushing barrel. The crusher carries out multiple times of crushing, so that working efficiency is improved, the powder passing rate is decreased, and smaller material blocks can be obtained; meanwhile, the function of the crusher is enhanced, work is stable, noise is low, manufacturing cost and maintenance cost are low, and the service life is longer.

Description

technical field [0001] The invention relates to a mining machine, in particular to a roller crusher. Background technique [0002] Crusher is a very common equipment in mines, which can crush ore into required size. In the existing roller crusher, if it is necessary to crush the ore that is too large into small pieces, a large toothed roller surface crusher cannot be used. Due to the need for strength, the teeth on the toothed roller surface cannot be used Small teeth, but the general roller crusher does not have enough strength to crush large ore, the number of crushing is small, the crusher also needs to replace components frequently, the cost of use is high, the work efficiency is low, and the obtained crushed material The fast powder passing rate is high, the size is uneven, and secondary processing is required. Contents of the invention [0003] The purpose of the present invention is to provide a four-roller crusher for the above-mentioned problems, which can impro...
