The difference between the cutter of the single-shaft shredder equipment and the double-shaft

Click here to get more.

The single-shaft shredder is equipped with only one moving shaft, and the blades are installed on this shaft to form a mutual shearing form with the fixed knife on the box. 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 static knife. Because the blade is spiral, the material will be squeezed, torn and sheared at the same time, so that the material can enter the equipment well and complete the work smoothly. The multi-shaft shredder has two moving shafts, both of which are inlaid with blades, and the two shafts rotate relative to each other to perform operations similar to a single-shaft shredder.

The working principle of single shaft shredder is different from that of double shaft

The working principle of the single-shaft shredder equipment is to drive the protruding knife on the shaft to cut the material to achieve a crushing effect through the rotation of the single-axis, which is equivalent to the same as the teeth, bit by bit, the material is smashed. purpose. The double-shaft crusher uses the speed difference between the two rotating shafts to produce tearing effect. The speed of the knife shaft is slow, the torque is large, and the crushing efficiency is high. It is suitable for domestic waste, industrial waste, electronic waste, biomass, food waste, and medical treatment. Waste, broken wood, garbage and other materials.

Difference in energy consumption and energy efficiency

For double-shaft shredders and single-shaft crushers, in terms of energy consumption and energy efficiency, single-shaft energy consumption is higher, and multi-shaft energy consumption is lower. The crusher blades are driven by the click belt, and then the reducer blades change Slow, large torque, strong crushing ability. In general, the applicability of multi-shaft crushers is stronger, so the use of multi-shaft crushers is more. The single-shaft crusher has a certain amount of use in the recycling of waste plastic pipes, rear wall PE pipes, and waste block plastic recycling. In terms of the size of the crushing, the single-shaft crusher has smaller pieces, and the multi-shaft crusher has larger pieces.

In general, the scale of use of dual-shaft crushers is becoming more and more extensive, but single-shaft crushers are more targeted and can be said to have their own strengths.So you need consinder your crusher material and your demand choose the most suitable shredder.

What's the difference between double-shaft shredder and single-shaft shredder

Double-shaft shredder and single-shaft shredder are the common types of shredders on the market. Many customers who have just come into contact with the solid waste crushing industry always can't distinguish clearly when choosing shredders. Let the professional shredder manufacturers show you the differences between double-shaft shredder and single-shaft shredder.

Different materials

Materials that can be shreded by the double-shaft shredder, such as waste tires, bulky waste, thin light metals, household appliances, hard copper, aluminum, paint barrels,, etc. In general, the torque of the double-shaft shredder is large, the crushing efficiency is high, and the applicability is stronger, so the use of the double shaft shredder is more. In terms of the grain size of the shredder, the block of the single shaft shredder is smaller. The single-shaft shredder is often used for paper mill waste cloth, leather leftovers, domestic garbage PE, PP plastic pipe plastic film, woven bags.

Different equipment structure

GEP double-shaft shredder is driven by "double motor + double planetary reducer" and uses the principle of mutual shearing and tearing between two relatively rotating cutters to crush materials. The material enters into the shredding box and is shredded into small pieces through the comprehensive action of tearing, extrusion and shearing of the shredding blade, forming repeated extrusion and tearing. So as to achieve the purpose of completely tearing up the material and discharging it from the lower part of the chamber. The main function is to reduce the volume and reduce the volume, which is convenient for transportation and lower treatment process. Single-shaft shredder adopts single shaft "motor + reducer" drive design to provide large shear force and ensure high crushing efficiency. It is often used for the fine crushing of solid waste, which can process the material to a smaller particle size at one time. Its main working principle is that the material enters into the shredding box through the feeding system. The box is loaded with a shredding blade. The pusher box pushes the material near the blade. The material is shredded into small pieces through the comprehensive action of tearing and extrusion of the shredding blade, which is discharged from the screen hole to achieve material shredding. The main structure of single shaft shredder is blade spindle, fixed blade, bearing box, box support, feeding system, hydraulic pushing system, power system, electrical control system, etc

Both the double-shaft shredder and the single-shaft shredder have their own advantages and disadvantages, and they are indispensable core equipment in the field of solid waste crushing. Choose the right equipment is good equipment, GEP ECOTECH the shredder manufacturers can according to your actual use, reasonable equipment selection, optimize your operating costs, if you need further understanding, please contact us at any time.
