Multi-stage crusher rotor with differential function

Abstract

The invention discloses a multi-stage crusher rotor with a differential function. The multi-stage crusher rotor comprises multiple single-stage rotors; a rotating shaft of each single-stage rotor is coaxial with a rotor body of each single-stage rotor; the rotating shafts of the single-stage rotors are coaxially arranged by adopting a hollow shaft structure in a sleeved manner; the rotor bodies ofthe single-stage rotors are connected in series; the multiple single-stage rotors are combined into a multi-stage rotor; the rotating shafts of the two single-stage rotors which are arranged in a sleeved manner are mutually rotationally matched; and each single-stage rotor is provided with an independent drive device and can rotate independently. For the multi-stage crusher rotor with the differential function, graded differential crushing is realized, the specifications of products capable of being crushed are complete, finished products can meet the requirements for different gradations anddifferent particle sizes, and high-quality raw materials can be provided to high-quality high-grade concrete; the single-machine multi-stage simultaneous crushing is realized, the single-machine crushing ratio is greatly increased, the crushing process is simplified, and the equipment and capital construction investments are reduced; and independent power drive grading is realized, and an implementation precondition is provided for comprehensive intelligent control.

Description

technical field [0001] The invention relates to the field of crushers used for crushing mineral products, in particular to a multi-stage crusher rotor with 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 ...

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
