3 Differences between One and Two Shaft Shredder

 When choosing an industrial shredder, the first question lots of the customers ask is what is the difference between single shaft shredder and double shaft shredder. One may not see the difference except their outlook, but they are very different in 3 points. In this article, we explain the differences between One shaft shredder and Two Shaft Shredder.

Machine Structure

Single Shaft Shredder is equipped with only one shaft welded with rotary blades. The rotor a hydraulic-actuated pusher arm. and a screen underneath the rotating shaft.

Double Shaft Shredder is built with two shafts of blades, which we also call dual shearing shafts. Its rotor consists of multiple disks of blades. The 2 rotors counter-rorate. There is no hydraulic-driven pusher or screen on this machine.

Application

Single Shaft Shredder is suitable to process thick and solid materials such as molding purgings, runners, sprues, plastic pallets, rubber rolls, wood lumbers, tree branches, bones, wood pallets, roll of films etc.

Double Shaft shredder excels in shredding large and relatively light or hollow products, such car/truck tires, film, plastic/steel drums, scrap TV/computer, scrap fax/printing machines, etc. Also, a mixture of the material streams like MSW can use double shaft shredder.

The output of both machines can go to secondary size reduction like granulator.

Operation Process

A single-shaft shredder, when the material is fed into the hopper, the pusher arm drives the material against the rotor, ensuring the material is efficiently in contact with and shredded by the rotary knives. The material will be repeatedly shredded till the shreds are small enough to pass throughput the screen. Therefore, you can get uniform output particles.

With a double shaft shredder, once the material is fed into the machine, the two shafts of cutting blades hook the material and then bite it until it’s fully broken down into pieces. No intervention of pusher ram or screen. The irregular sizes of shredded particles directly fall to the collection bin/conveyor.

The Composition of Plastic Waste – Latest Analysis Year 2020

Image
  What source of the industry creates most of the plastic waste? There is a huge increase in plastic consumption in our daily lives. Plastic waste can be divided into commercial and industrial wastes. Many of these plastic products are single-used. That is, they are thrown away after one-time usage. For example, disposable plastic packaging, food container, cup, tablecloth and hand gloves are the regular items. The Composition of Plastic Waste: Pre-use and Post-use Plastic Other types of plastic waste include pre-use and post-use plastic. Pre-use plastic is mainly rejected products that do not meet the criteria in terms of size, colour, hardness and other properties. This also includes the byproducts like flesh and sprue during the process of plastic product manufacturing (e.g. molding, blow molding, thermal forming). Post-use plastics include plastic bottles, pails, casing; rigid plastics such as pipes and moldings, plastic foams or expanded polystyrene; and flexible plastics such as

What is ocean plastic pollution?

  Where does the plastic pollution in the ocean come from? What is ocean plastic pollution? Marine pollution is a combination of solid waste and chemicals that originate from the land. With the help of rainwater and wind, the pollutant is driven into the ocean. 3% of the worldwide plastic waste goes to the ocean according to the study. As more than 80% of the global plastic waste is not recycled, it is not surprising that abundant waste is accumulating in the ocean. In 2010, this was about 8 million tonnes. Before we dive into the question of where does ocean plastic waste comes from, we need to know about mismanaged plastics in the globe. The definition of mismanaged plastics is plastic waste that does not properly collect and recycle, instead, it ends up in landfills and scrap yard and directly pours into the river, lake and ocean. The graph shows more than half of the mismanaged stems from East Asia and the Pacific. The rest of the regions account for 40%. North America scores the l
