Retsch® SM 300 Cutting Mill, 5 Liters, 220-230V, 50/60 HZ

The RETSCH SM 300 is a high‑performance laboratory cutting mill designed for tough size reduction tasks. It handles soft to medium‑hard, elastic, fibrous, and heterogeneous sample materials—think plastics, wood, electronic waste, plant materials, and more. With its powerful 3 kW motor enhanced by RES (Retained Energy Stabilization) technology, it delivers high torque, reducing the risk of blockages and enabling efficient grinding to a defined fineness using bottom sieves. The SM 300 is built for flexibility, durability, and ease of cleaning, making it suitable for demanding applications in research, production, and quality control.

Key Features

• Drive & Power: 3 kW motor with flywheel mass for high torque via RES technology.
• Speed Range: Variable rotor speed from ~ 100 to 3,000 min⁻¹, allowing adaptation to different materials and desired fineness.
• Feed & Output Size: Accepts sample feed sizes up to ~ 60 × 80 mm; final fineness adjustable using bottom sieves in the 0.25–20 mm range.
• Rotor & Cutting System: Double‑acting cutting bars, choice of rotors (parallel section, 6‑disc, V‑rotor), for effective shearing/cutting. 
• Collection / Discharge Options: Standard gravity outlet with 5 L collecting receptacle, optional cyclone‑suction versions, larger collection vessels (up to 30 L) for high throughput or sensitive materials. 
• Material & Build Options: Versions in stainless steel (including 316L food‑grade) or heavy‑metal‑free materials for applications needing hygiene or special material compatibility.
• Ease of Use & Cleaning: Fold‑back hopper, smooth interior surfaces, push‑fit rotor and bottom sieve, safety interlocks (door cannot open when motor is running), engine brake.
• Sample Handling Advantages: Low speeds help reduce heat build‑up and minimize over‑generation of fines, which is beneficial for temperature‑sensitive materials.
