Rotational shear type double-shaft single crusher for solid waste

Abstract

The invention discloses a rotational shear type double-shaft single crusher for solid waste. The crusher comprises a box and two mutually parallel main shafts, wherein the main shafts are installed in the box; a plurality of crushing knives are installed on each main shaft; the center lines of the two main shafts are in the same horizontal plane; a plurality of fixed knives in staggered arrangement with the crushing knives are respectively installed on the two sides and middle part of the box body; and a driving device is connected with each main shaft. In the invention, two power units for respectively driving the main shafts to carry out the crushing work, each main shaft can independently complete the material crushing function, and each main shaft can both forwardly rotate and reversely rotate for crushing, so the crushing efficiency is high; because both forward rotation and reverse rotation are for carrying out the crushing work, when the external resistance is so large that the material can not be crushed, the main shafts automatically reversely rotate for crushing without shutting down or plugging, so the production efficiency is high; and the gaps between the fixed knives and the crushing knives can be adjusted to ensure the best shearing state.

Description

technical field [0001] Type the technical field description paragraph here. The invention relates to a crusher, in particular to a rotary shear type double-shaft single crusher for solid waste. Background technique [0002] At present, there are all kinds of crushers in various industries, and the performance and indicators of the crushers are not the same. The most widely used are crocodile crushers, gyratory crushers, cone crushers and cone crushers. etc. These crushers can only crush a specific material. In the garbage disposal industry, especially in the industrial waste recycling industry, large pieces such as used bicycles and refrigerators cannot be processed by the above crushers, nor can they be processed by the current garbage disposal industry. The two-shaft shear crusher commonly used in the industry is crushed. Because the two-shaft shearing crusher moves in the opposite direction through the two shafts, and the rotary shearing crushing has a certain range of ...

[0002] At present, there are all kinds of crushers in various industries, and the performance and indicators of the crushers are not the same. The most widely used are crocodile crushers, gyratory crushers, cone crushers and cone crushers. etc. These crushers can only crush a specific material. In the garbage disposal industry, especially in the industrial waste recycling industry, large pieces such as used bicycles and refrigerators cannot be processed by the above crushers, nor can they be processed by the current garbage disposal industry. Two-shaft shear crusher commonly used in the industry for crushing

Because the two-shaft shearing crusher moves in the opposite direction through the two shafts, and the rotary shearing crushing has a certain range of requirements for the particle size of the crushed material. Industrial waste with a large particle size exceeding its rated maximum value cannot be crushed with it. , but manual splitting and then crushing is labor-intensive and inefficient

Moreover, if the two-shaft shearing crusher feeds unevenly, it will easily cause the crusher to block the material. After the material is blocked, it needs to be cleared on standby, and the work efficiency is low.

And the double-shaft rotary shearing crusher can only complete the crushing by rotating in the confrontation, otherwise it is non-shearing work, and the crushing efficiency is low
