Retsch Cross Beater Mill SK 300, Up to 25mm, 2000-4000 min⁻¹, 220-240V, 50/60 Hz, Stainless Steel

The Retsch Cross Beater Mill SK 300 Stainless Steel is designed for preliminary and fine size reduction of medium-hard, brittle, and fibrous materials. Built for batch-wise or continuous operation, this robust mill is ideal for use in laboratories as well as under tough industrial production conditions. The SK 300 offers exceptional grinding performance and durability, with a powerful drive system and a maximum rotor speed of 4000 min⁻¹—often achieving a final fineness of less than 100 µm in a single pass.

Key Features:

• Material: Stainless steel (grinding chamber, components)
• Feed Size: Up to 25 mm
• Speed: Adjustable from 2000 to 4000 min⁻¹
• Voltage/Frequency: 220–240 V, 50/60 Hz
• Application: Size reduction of medium-hard to brittle materials for sample preparation and industrial processing
• Performance: Final fineness <100 µm possible in one process
• Sieve Range: Bottom sieves available with aperture sizes from 0.12 to 10 mm
• Ease of Cleaning: Removable cassette, hopper, and push-fit rotor for rapid cleaning and minimal downtime
• Safety: Quick-action door lock, safety lock, and electric brake
• Collection System: Ring filter and 5 L collecting vessel with dust-tight bayonet catch

Function Principle:
Size reduction in the SK 300 occurs through impact and shearing effects. Air is drawn in through the hopper by the rotating cross beater, which enhances discharge and transports airborne fine material toward a downstream filter system for separation.

Scope of Supply:
Cross Beater Mill including grinding insert, cross beater, baffle plates, filter hose, and 5 L collecting vessel.

Note: Bottom sieves and base frame must be ordered separately. Additional sieve and feeder sizes are available upon request.
