Are High-speed Crushers Prone to Material Loss? Analysis of Process Advantages of 350 Type Spiral Crusher Low-speed Fine Crushing

In the plastic regeneration crushing process, many manufacturers blindly choose high-speed impact crushers, long plagued by frequent cutter chipping, excessive crushing dust, uneven particles, serious material waste, high equipment noise and vibration. These problems not only increase operation and maintenance costs, but also affect the quality of finished granulated products. With its unique low-speed spiral shearing process, the 350 type spiral crusher has become the preferred equipment for fine crushing of hard and large-size plastics, perfectly solving the pain points of traditional crushing equipment in the industry.

Traditional high-speed crushers crush materials by high-speed rotating impact. When processing thick-walled pipes and hard plates, they are prone to incomplete crushing, local material chipping and excessive powder generation, resulting in rapid cutter wear and high failure rates. Meanwhile, high-speed operation produces strong vibration and noise, poor workshop production environment and high material loss rate, directly reducing overall production profits. In contrast, the 350 type spiral crusher abandons the high-speed impact mode and adopts the 46r/min low-speed high-torque spiral shearing principle. It crushes materials through cutter meshing and shearing instead of violent impact, improving crushing quality and equipment stability fundamentally from the process.

The core transmission is equipped with a ZSY280 three-stage hard tooth surface reducer. The gears are processed by carburizing, quenching and precision grinding, featuring high transmission efficiency and large bearing torque. It can easily cope with the instantaneous impact force of hard material crushing, buffer equipment load, eliminate stalling, stuffy machine and transmission damage, and ensure long-term continuous operation of the equipment. The core spindle is made of integral forged 40Cr material with quenching and tempering reinforcement treatment, combining rigidity and toughness. It will not deform or vibrate during heavy-duty operation, ensuring the operation precision of the cutter disc.

The crushing core adopts a high-end SKD11 alloy cutter group. 24 movable cutters and 17 fixed cutters are arranged in a staggered spiral with accurate meshing gaps and uniform shearing force. The high-hardness cutters are wear-resistant and chipping-resistant, with a service life far exceeding ordinary high-speed steel cutters. The 300mm precision cutter disc matched with the 800*800mm large feeding port supports direct crushing of large-size plastics without pretreatment, greatly improving production efficiency. With an overall size of 2400*1250*1500mm, the equipment occupies small space and is easy to install. The 800mm standard discharge height adapts to the docking of various automated production lines.

In summary, this spiral crusher perfectly meets the current refined production needs of plastic regeneration with the core advantages of low-speed low loss, durability, high-quality crushing, low noise and energy saving. It is especially suitable for processing hard, large-size and thick-walled plastic materials, helping manufacturers greatly reduce operation and maintenance costs, cut material loss and improve finished product quality, serving as a high-quality upgrade alternative to traditional high-speed crushers.

FAQ

Q1: What is the core difference between the spiral shearing process and the ordinary impact process?

A: The ordinary impact process crushes materials through high-speed collision, resulting in more dust, poor particle quality and high cutter loss. The spiral crusher adopts a low-speed spiral shearing process for layered fine crushing, featuring uniform particles, extremely low dust, small cutter wear and low equipment vibration and noise, which is more suitable for refined and low-loss mass production.

Q2: Do SKD11 cutters have a longer maintenance cycle than ordinary cutters?

A: Yes. SKD11 high-hardness alloy cutters are wear-resistant, chipping-resistant and high-temperature resistant, suitable for long-term crushing of hard materials. They do not require frequent polishing and replacement under normal working conditions, with a maintenance cycle more than 3 times that of ordinary cutters, greatly reducing equipment operation and maintenance time and costs.
