Single Shaft Shredder: A High-Efficiency Player in Multi-Field Waste Disposal

1. Core Overview of Single Shaft Shredder

A single shaft shredder is a mechanical crushing equipment with a single rotor as its core, mainly composed of a cutter shaft, fixed knife, bearing box, box bracket, feeding system, hydraulic system, power system, and electrical control system. Through the rotation of the cutter shaft and the cooperation of the fixed knife, it tears and shears various waste materials, playing a key role in the field of waste recycling and disposal.

2. Wide Application Scenarios of Single Shaft Shredder

(1) Vehicle Parts Field

It can handle waste tires, oil filters, engine casings, waste copper and aluminum parts, waste steel plates, and waste iron forklift pallets with a thickness of less than 25.4mm. For example, waste tires generated by auto repair shops, after being crushed by a single shaft shredder, the rubber particles can be used to make recycled rubber products, and the metal skeleton can be recycled and reused.

(2) Barrel Material Field

It covers plastic barrels, metal barrels, paint buckets, IBC tanks, garbage cans, packaging barrels, etc. For instance, discarded IBC tanks from chemical enterprises can be crushed by a single shaft shredder to separate and recover the plastic of the tank body and the metal frame.

(3) Metal Products Field

It includes waste materials such as aluminum, cans, metal cans, waste aluminum sheets, waste steel, iron sheets, and copper sheets. For example, a large number of cans in recycling stations, after being crushed by a single shaft shredder, are convenient for subsequent metal smelting and regeneration.

(4) Waste Disposal Field

It can handle domestic waste, kitchen waste, industrial waste, garden waste, etc. Taking municipal domestic waste as an example, the single shaft shredder can crush the bulky waste in it, reduce the volume of waste, and facilitate subsequent sorting, recycling and landfill disposal.

(5) Plastic Products Field

It involves plastic pipes, pipe fittings, plastic bottles, plastic racks, plastic blocks, plastic cans, rolled films, woven bags, etc. For example, waste plastic pipe fittings from plastic processing plants can be re-granulated to produce new plastic products after being crushed.

(6) Wood and Paper Field

It can handle branches, stumps, construction formwork, wooden blocks, newspapers, cardboard, corrugated paper, copy paper, etc. For example, waste construction formwork on construction sites, after being crushed by a single shaft shredder, can be used as biomass fuel or papermaking raw materials.

(7) Electronic and Electrical Field

It includes circuit boards, computer cases, CD discs, waste TVs, waste washing machines, etc. For example, waste computer cases, after being crushed, can separate plastic and metal for recycling respectively.

(8) Glass Products Field

It covers glass wool, glass cups, FRP products, etc. For example, discarded FRP products, after being crushed by a single shaft shredder, can be used to make glass fiber recycled products.

(9) Medical Waste Field

It can handle small medical devices, clinical waste, infectious waste, various plastic waste, latex material waste, syringe waste, pharmaceutical waste, etc. In medical waste disposal centers, single shaft shredders can crush medical waste to facilitate subsequent harmless disposal.

3. Distinctive Features of Single Shaft Shredder

(1) Strong Material Applicability

Yuxi mini single shaft shredder is suitable for shredding materials with strong entanglement and materials containing a small amount of thin metal. For example, waste wires and cables have strong entanglement between the internal copper core and the external plastic sheath, and the single shaft shredder can effectively crush and separate them.

(2) Advantage in Cutter Cost

The use and maintenance cost of the cutter is low, and it is convenient to replace the cutter. Compared with other types of shredders, the cutter structure of the single shaft shredder is reasonably designed, and the wear rate is slow. Even if replacement is needed, the operation is relatively simple, which can effectively save the time and capital cost of equipment maintenance.

(3) Advantage in Equipment Price

The price of single shaft shredder is lower than that of double shaft, triple shaft and quadruple shaft shredders. For small and medium-sized enterprises or start-up waste recycling enterprises, the price advantage of single shaft shredder makes it a more cost-effective choice.

(4) Adjustable Finished Product Size

The size of finished products can be adjusted according to the aperture of the screen, ranging from 25.4mm to 63.5mm. Users can flexibly replace screens with different apertures according to the needs of subsequent processing or recycling to obtain crushed products with the required particle size.

4. Key Points for Equipment Maintenance of Single Shaft Shredder

(1) Inspection of Component Connections

Regularly check whether the connections of various parts of the equipment are loose to ensure that all parts are firmly connected during the operation of the equipment, and avoid equipment failures or safety accidents caused by looseness.

(2) Inspection of Motor Current

Regularly check the current of the main motor of the equipment. The motor power is usually between 15kW and 90kW. Abnormal conditions such as overload and material blockage of the equipment can be found in time through changes in current for timely handling.

(3) Inspection of Hydraulic System

Regularly check the hydraulic system. The pressure of the hydraulic system is usually maintained between 16MPa and 25MPa, including the oil quantity, oil quality of hydraulic oil and the tightness of hydraulic pipelines, to ensure the normal operation of the hydraulic system and provide stable power for the feeding and other actions of the equipment.

(4) Inspection of Cutter Wear

Regularly check the wear of the cutter. Once the cutter is found to be severely worn, it should be replaced in time to ensure the crushing efficiency and quality of the equipment.

With its wide application scenarios, distinctive features and convenient maintenance methods, the single shaft shredder has become an important equipment in the field of waste disposal. It provides an efficient solution for the recycling and reuse of various wastes and contributes to the development of circular economy.
