Specific Physical Characteristics of Each Waster Material V.S. Individual Design of Baler Structure

PET bottle is a material that occupies considerable space and with a big compaction ratio. Hence, PET bottle balers specially designed for this material usually have a big compressing chamber and with long stroke cylinders. As a result, PET bottle balers are comparatively taller than other balers.

The big friction between textile and inner wall of compressing chamber makes bale ejection not an easy job.  Because of this, textile balers are designed with lifting chamber door or four-sided door for an quick access of getting bales out.

To press the material with a big spring-back force/elasticity such as tyres, balers should install anti-bound device such as hooks inside the compressing chamber to prevent material bouncing back when platen moves upward.

Waste steel is a hard material and requires joint work of compressing force from different directions. Normally, three directions compressing is adopted for metal balers.
