The difference between the double shaft shredder and the single shaft shredder

The types of shredders are very wide, with gravel, shredded paper, shredded garbage, etc., which are widely used in industrial applications. The shredder can be divided into two types according to the working principle, a single-shaft shredder and a double shaft shredder. So, what are the differences between the single-shaft shredder equipment and the double shaft shredder equipment? And the scope of the double shaft shredder  is very extensive. Let's take the garbage crusher as an example. The garbage crusher is a type of crusher that has emerged in recent years. It can be applied in a wide range of industries, and it can not be shredded by some ordinary shredders. It can have a good treatment effect.

The rotary cutter shaft of the single-shaft shredder is equipped with a squeezing type movable knife. The number of movable knives is determined according to different types and the size of the rotation, and the movable knives are a four-corner surface that can be used with a knife. Angle, until the four sides are blunt and then sharpened, because it is a claw type moving knife, rotary cutting, and the fixed knife and moving knife are imported from Europe, and then heat treated. Therefore, the service life is long-lasting, the cutting ability is strong, the production capacity is high, the normal use of more than 1000 tons requires the sharpening of the knife, the material is driven by the hydraulic cylinder during the machine operation, and is equipped with pneumatic clamping equipment, PLC programmable control, high degree of automation Easy to operate.

2. Different principles:

The working principle of the single-shaft shredder equipment is different from that of the double shaft shredder. The working principle of the single-shaft shredder equipment is to smash the material by a single-shaft rotation to drive the protruding tool cutter on the shaft to achieve a crushing effect, which is equivalent to the tooth. Like the cockroach, the material is smashed bit by bit to achieve the purpose of smashing.

 The two-shaft shredder adopts the microcomputer automatic control system, and has the functions of start, stop, reverse and overload automatic reversal control, featuring low speed, high torque and low noise. The bearing seat adopts the split type, and the disassembly and replacement of the knife is easy and convenient, and it is suitable for the material with large torn, extra thick and difficult to break.

3. Different energy consumption:

 Compared with the single-shaft shredder, the double shaft shredder has a higher energy consumption for single-shaft energy consumption and a lower energy consumption for the two-shaft. The shredder blade is driven by a click belt. Then the blade of the reducer is slowed down, the torque is large, and the shredding ability is strong. Under normal circumstances, the applicability of the twin-shaft shredder is stronger, so the use of the double-shaft shredder is more. The single-shaft shredder has a certain amount in the recycling of the waste block plastic in the recycling of the waste plastic pipe back wall PE pipe. Usage amount. In terms of the shredded particle size, the uniaxial comminuted shredded block is smaller, and the shredded shredder of the biaxial shredder is larger.

 4. Different structure:

A single-shaft shredder, this form of metal shredder is only equipped with a moving shaft, on which the blades are mounted, forming a mutual shearing pattern with the fixed knife on the casing. The main shaft is driven by the motor and the reducer, and the material is driven by the spiral blade to enter the gap between the movable knife and the stationary knife. Since the blade is spiral, the material will be squeezed, cracked and sheared at the same time, so that the material can enter the device well and complete the work smoothly.

The twin-shaft shredder is similar to the single-axis metal shredder, except that the moving shaft is turned into two, each with a blade, and the two shafts are rotated relative to each other, and the material is similar to a single-shaft shredder. operating. The two-axis shredder is equipped with two motors that have enough power to shred some of the larger, harder materials.
