Paired roller type crushing equipment for building construction

Abstract

The invention provides paired roller type crushing equipment for building construction. The paired roller type crushing equipment comprises a gear seat, a connection seat, a limiting groove, a seconddischarging hopper, a belt wheel, a discharging cloth bag, a stirring shaft, a gear reversing box and an inserting type discharging plate, wherein a crushing cabin is of a rectangular cabin body structure and is mounted on a bottom surface of a bracket through a bolt; a square feeding opening is formed in a top surface of the crushing cabin; a feeding opening with an inverted trapezoidal structureis mounted at the top end of the feeding opening; two paired rollers are arranged; the discharging plate on the top layer is inserted to directly discharge materials; when the device is used for finely crushing building lime materials, the top-layer discharging plate can be inserted and a stirring device in a bottom-layer comprehensive discharging structure is used for stirring and squeezing, sothat fine powdery discharging is realized; visibly, the structure can be suitable for occasions of crushing mine stones into stones and also can be suitable for occasions for crushing lime blocks in the building construction into powder; the paired roller type crushing equipment has good structure comprehensive performance and strong selective practicability.

Description

technical field [0001] The invention belongs to the technical field of crushers and construction equipment, and more specifically relates to a pair of roller crushing equipment used in construction. Background technique [0002] Crusher is also called stone crusher, and stone crusher can be divided into medical stone crusher and mining stone crusher according to major categories. In principle, the mining crusher is suitable for crushing a large number of hard rocks in mines. Its typical granite output particle size is less than or equal to 40mm, which accounts for 90%. The crushing ratio is large, and the crushed material is in the form of cubic particles. Mining crushing machinery refers to the crushing machinery in which the content of the particle size greater than 3 mm in the discharge accounts for more than 50% of the total discharge. [0003] For example, the Chinese patent No. is; application number CN201710593113.0 discloses a mining rock crusher with dust removal ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a pair of roller crushing equipment for building construction, to solve the problem that the existing crushing equipment with the above-mentioned structure has a single structure and poor functionality, or it can be used in the construction industry to finely crush lime blocks. The pressure-type crushing device is either used in the mining industry to carry out particle-type crushing of ore materials. The two occasions cannot use the same equipment, so the problem of poor practicability
