Vertical shaft-type crushing machine with differential function

Abstract

The invention discloses a vertical shaft-type crushing machine with a differential function. The vertical shaft-type crushing machine with the differential function comprises a box body and a plurality of singe-stage rotors; a feeding port and a discharging port are respectively formed in the upper end and the lower end of the box body; the rotating shaft of each single-stage rotor is coaxial withthe rotor body thereof; the rotating shafts of the plurality of the single-stage rotors are arranged in a sleeving manner coaxially by adopting a hollow shaft structure; the rotor bodies of the plurality of the single-stage rotors are connected in series; the plurality of the single-stage rotors are combined into a multi-stage rotor; the multi-stage rotor is mounted in the box body in a verticalrotating manner; the rotating shafts of the two single-stage rotors which are arranged in the sleeving manner are in rotatable fit with each other; each single-stage rotor is provided with an independent driving device and can rotate independently; a counterattack lining is mounted around the inner wall of the box body; and hitting hammers are mounted on the periphery of the rotor body of each single-stage rotor. According to the vertical shaft-type crushing machine with the differential function, staged differential crushing and single-machine multi-stage simultaneous crushing are realized; the specifications of crushable products are complete; the crushing ratio of a single machine is greatly increased; staged independence of power driving is realized; and implementation preconditions are provided for implementing integrated intelligent control.

Description

technical field [0001] The invention relates to the field of crushers used for crushing mineral products, in particular to a vertical shaft crusher with a differential speed function. Background technique [0002] With the rapid development of my country's economy and the huge scale of infrastructure construction, the demand for building materials will be astonishing. China is also a country with a large demand for mineral products, and the mineral product processing market has broad prospects. At present, in China and even abroad, the crushing and processing equipment of mineral products has been hovering in the "one low" and "three high" of low efficiency, high energy consumption, high wear and high pollution. [0003] With the upgrading of the industry, the mineral product market has become subdivided, which requires products to have customized characteristics. To meet the requirements of high-grade concrete, it is also necessary for the mining machine to have a large c...

Problems solved by technology

[0003] With the upgrading of the industry, the mineral product market has become subdivided, which requires products to have customized characteristics. To meet the requirements of high-grade concrete, it is also necessary for the mining machine to have a large crushing ratio to reduce infrastructure investment, reduce environmental protection pressure, optimize the production process to achieve informatization and intelligent production, and traditional ore crushing processing machinery is difficult to achieve
