Abstract

The invention relates to a crushing device, and particularly discloses a pair roller crushing machine. The pair roller crushing machine is provided with a driving roller assembly and a driven roller assembly, wherein when too hard materials pass through a position between the driving roller assembly and the driven roller assembly, the driven roller assembly can realize the active avoiding. A sievescreen is arranged under the driving roller assembly and the driven roller assembly; the sieve screen is driven to swing by a crank rocker mechanism; a material pushing plate is arranged on the sievescreen and is driven by an air cylinder; gas is supplied to the air cylinder by a gas generating mechanism; the material pushing plate is driven to do clearance reciprocating movement, so that wastematerials on the sieve screen can be discharged. Through the sieve screen arranged under the driving roller assembly and the driven roller assembly, after the retreating avoidance of the driven roller, uncrushed raw materials can be mixed into the crushed raw materials; through the sieve screen, unqualified waste materials are screened out.

Description

technical field [0001] The invention relates to a crushing device, in particular to a pair-roll crusher. Background technique [0002] The hardness of the carbon black agglomerate is not high, and it is relatively easy to crush it. It is required that the crusher has a certain ability to overcome obstacles, the output particle size can be adjusted in a small range, and the floor space should not be too large. At present, the roller crushers on the market all have the function of overcoming obstacles, that is, when encountering too hard or unbreakable objects, one of the two rollers can automatically retreat to protect the machine from damage; the well-known one has the function of overcoming obstacles The structure of the double-roller crusher is as follows: in order to achieve the purpose of overcoming obstacles, the bearing seats at both ends of a roller can slide outward, and the outside of the bearing seats is pushed by springs so that they can be reset in time after ove...
