Bale Breaker

Bale Breaker

Product introduction:

Bale breaker is a new machine applied to waste paper pulping, mainly used for breaking waster paper bales and screening light and small contaminants under dry process, and facilitating the removal of big rejects after breaking bales, especially applied when the conveyor continuously sorts the material with high efficiency. Taking into full consideration of weight, volume and packing tightness of waste paper bales, especially imported waste paper bales, the machine was designed rationally according to situation of raw material. In special, this machine helps sort mass waste paper for large-scale production lines beyond manpower.

Structure and Principle

Equipment Structure:

Bale breaker of this series is constructed including cylinder, feeding device, cylinder supporting roller, support frame, rejects tank, cylinder axial positioning wheel, outer shield and power transmission system, etc. Lifting board, spiral band and rejecting perforations are arranged inside the cylinder. Lifting board and spiral band are fixed on inner wall of cylinder and rejecting perforations are through-holes opened on cylinder body. Two raceways are fixed around outer side of cylinder and fall onto the cylinder supporting rollers. Rejects tank is made of two sloping plates set on the bottom part of cylinder. Cylinder axial positioning wheels are set on the bottom center inside the two raceways. Feeding device is installed on the feeding connection of cylinder.

 

Auxiliary equipment and technological process:

This machine and feeding chain conveyor and sorting chain conveyor (or sorting belt conveyor) work together as a complete set of waste paper bale breaking and dry screening system.

Technological process: waste paper-chain conveyor-bale breaker-sorting chain conveyor (or belt conveyor)-pulper.

 

Working Principle:

Tightly baled waste paper is transferred to feeding device by chain conveyor, and then enters the rotating cylinder for breaking and primary screening. Lifting boards lift materials to a certain height and then loose. Materials freely fall and hit the spiral band, other lifting boards and inner wall of cylinder, and then are thrown, pressed, smashed, crushed, stabbed and torn. At the same time, materials move forward under functioning of spiral band. This process repeats again and again. Then tight bales is broken. Hard particle impurities are separated through the holes and then fall into the rejects tank. Loosened waste paper is put on sorting chain conveyor through outlet of bale breaker, then sorted manually and conveyed to pulping system.
