Product Overview

This industrial crusher is a high-performance size reduction unit engineered for demanding laboratory and production environments. It transforms bulk solid materials into uniform granules through a combination of cutting, impact, and extrusion forces generated by precisely machined rotary and stationary knives. The system delivers exceptional crushing capability across a wide range of material hardness and fibrousness, making it a cornerstone of sample preparation workflows.
Designed for versatility, the equipment services diverse sectors including pharmaceuticals, food processing, chemical manufacturing, agricultural research, environmental testing, and plastics recycling. Its robust construction and powerful motor ensure consistent throughput even with tough, high-tenacity substances, while intuitive controls allow operators to quickly adjust output particle size by swapping screen meshes.
Backed by precision engineering and rigorous quality assurance, this crusher provides years of trouble-free operation. Heavy-duty components and advanced manufacturing techniques minimize vibration and noise, while the compact, mobile design fits seamlessly into crowded labs or production lines. Users can trust it to deliver repeatable results under continuous use.
Key Features
- Powerful Motor and Durable Knife Set: A 2.2 kW motor paired with nine rotating and two stationary knives made of high-carbon steel ensures efficient crushing of hard, tough, and fibrous materials. The hardened blades maintain sharpness over extended use, reducing downtime.
- Adjustable Screen Mesh for Controlled Output: Interchangeable screens with apertures from 5 mm to 20 mm allow precise control of final particle size. This flexibility enables the unit to handle tasks from coarse pre-crushing to fine granulation without compromising throughput.
- Robust Construction and Mobile Design: Built on a reinforced steel frame with four heavy-duty casters, the crusher is both stable during operation and easy to reposition. Its low vibration and quiet running make it ideal for noise-sensitive laboratory environments.
- Large Feed Throat for Bulk Processing: The generously sized hopper opening (200 × 120 mm) accommodates bulky samples and reduces the need for pre-breaking, improving workflow efficiency. An integrated catch bin simplifies collection and cleaning.
- Safety and Ease of Use: The machine features straightforward start/stop controls and a secure feed chute design that protects operators from moving parts. Rapid access to the crushing chamber allows quick cleaning and screen changes between batches.
- Wide Material Compatibility: Engineered to process everything from brittle minerals to elastic polymers, the crusher excels with pharmaceuticals, chemicals, food ingredients, electronic waste, and wood. Its aggressive knife geometry prevents clogging and ensures uniform particle shape.
- Scalable Performance Options: While this model offers 30–150 kg/h capacity, the series includes larger variants with up to 400 kg/h throughput, enabling users to select the optimal balance of footprint and output for their specific application.
