Industrial claw type crusher for crushing shoe last materials

Advantages (Core Strengths for Shoe Last Crushing)

1. Strong Crushing Capacity for Hard/Thick-Walled Materials

   Shoe last materials are typically hard plastics (e.g., ABS, PC) with thick walls (to maintain structural stability). The claw-type crusher’s core design—high-strength claw-shaped rotating knives + fixed knives—adopts a "shearing + tearing" combined crushing method, rather than simple impact. This allows it to easily break through the high rigidity of shoe lasts, avoid material slipping during crushing, and efficiently process thick-walled shoe last blanks or waste products that are difficult for ordinary blade crushers to handle.
   
   
2. Uniform Crushing Particle Size, Low Material Loss

   The claw-shaped knives are arranged in a staggered and optimized manner (usually 3-6 groups), and the gap between the rotating knives and fixed knives can be adjusted (0.5-3mm). When crushing shoe lasts, the materials are repeatedly sheared and torn instead of being crushed by brute force, which reduces the generation of fine powder (a common problem with hammer crushers) and ensures that the crushed particles are uniform (generally 5-20mm, adjustable according to recycling needs). This is critical for subsequent processes such as plastic granulation (uniform particles improve granulation efficiency and product quality).
   
   
3. High Equipment Durability, Low Maintenance Cost
   • The claw-shaped knives and fixed knives are made of high-wear-resistant materials (e.g., 9CrSi, H13 steel), which have strong resistance to impact and wear—especially suitable for the hard texture of shoe last materials. Under normal use, the service life of the knives can reach 3000-5000 hours (2-3 times longer than ordinary carbon steel knives).
   • The crusher’s main shaft is supported by heavy-duty bearings, and the crushing chamber is lined with wear-resistant plates, which reduces the wear of the equipment body caused by hard materials.
   • Maintenance is simple: only regular knife grinding (no need for frequent replacement) and bearing lubrication are required, and the average maintenance time per month is less than 2 hours.
4. Good Safety and Environmental Protection Performance

   To adapt to industrial production scenarios, most models are equipped with multi-layer safety and environmental protection designs:
   • Safety protection: Equipped with an emergency stop button, a feed port safety cover (the equipment stops automatically when the cover is opened), and an overload protection device (to prevent motor burnout caused by excessive material input).
   • Noise and dust control: The hopper and crushing chamber adopt a double-layer structure filled with sound-insulating cotton (noise during operation is 75-85dB, lower than the national industrial noise standard of 90dB), and some models are optional with a dust collection system (to collect fine dust generated during crushing, avoiding air pollution).
