What's The Difference Between Single Shaft Shredder & Double Shaft Shredder?

1. Structurer Difference

Double shaft shredder is mainly composed of

· feed hopper

· two shredded spindles

· shredding blades

· discharge hopper

Single shaft shredder is mainly composed of

· feed hopper

· stationary cutter

· shredding blades

· Screen

2. Blade Type Differences

Single shaft plastic shredder only has one rotary shaft holding all the cutting blades. When the shaft rotates, carrying the cutting blades, there’s a shearing force between the rotating blades and the stationary cutter.

Double shaft shredder has two rotary shafts, both hold many blades. The two shafts rotate relative to each other to cutting materials.

3. Different Materials To Be Cutted

Double Shaft Shredder features high torque and high efficiency, suitable for shredding domestic waste, industrial waste, electronic waste, biomass waste, kitchen waste, medical waste, wood chips, and other materials, etc.

Single shaft shredder is commonly used in paper mill processing waste fabric, leather scrap, domestic waste, PE, PP, plastic pipe, plastic film, woven bags, wire and cable cans, aluminum scrap, and other aluminum products.

Double Shaft Shredder Working Principle

Double-shaft shredder, also known as double-shaft shredder, shearing design principle, alloy knife material, through shearing, tearing, and extrusion to reduce the size of the material. Strong impact resistance, broken metal knives do not break.

The double shaft shredder is mainly used in domestic waste, industrial waste, and leather scraps, organic waste, medical waste, RDF, hazardous waste, bulky waste, paper mill twisted rope, etc.

The working principle of the double-shaft shredder: During the crushing process, the claws on the rotor pull the material into the crushing cavity. The blades are arranged in a staggered and occlusal manner so that the material can be cut and broken in both the horizontal and vertical directions at the same time. After the material is broken, it is intercepted and peeled off by the partition and finally discharged downward.

The main working part of the crusher is a pair of relatively rotating rollers, and the rollers are equipped with gear teeth arranged in a spiral. After the material enters the machine, it is bitten and sheared by the gear teeth made of staggered high-hardness wear-resistant materials, and is split, broken and pulverized to a size lower than the set size, and then forced to be excluded from the machine. The roller is driven by the motor through the reducer and has a large torque. When encountering difficult-to-break objects, it will automatically reverse under the action of the PLC automatic control system, and rotate forward and reverse many times until the materials are broken and discharged. This principle equipment has different names in various industries: metal shredder, coal grading crusher, domestic waste shredder, construction waste shredder. According to its own structural characteristics, it can be called a spiral-toothed roller crusher (shredder), which is commonly used in the form of double shaft (double toothed roller), as well as single shaft and four shafts (four-toothed roller).
