Retsch Cross Beater Mill SK 300 up to 25mm, 2000-4000 min-1, 220-240V, 50/60 Hz, Cast Iron

The Retsch Cross Beater Mill SK 300 Cast Iron is a durable and high-performance milling solution for coarse and fine size reduction of medium-hard and brittle materials. Designed for both laboratory and industrial applications, this robust mill handles batch-wise or continuous processing with ease. Its powerful motor and adjustable rotor speeds of 2000–4000 min⁻¹ allow the unit to achieve final fineness levels below 100 microns in many applications.

Key Features:

• Brand: Retsch
• Material: Cast iron grinding insert and housing for enhanced durability in tough conditions
• Feed Size: Up to 25 mm
• Speed: Adjustable between 2000 and 4000 min⁻¹
• Voltage/Frequency: 220–240 V, 50/60 Hz
• Application: Suitable for processing minerals, coal, coke, glass, gypsum, construction materials, and more
• Final Fineness: <100 µm depending on sample and setup
• Sieve Options: Bottom sieves with aperture sizes from 0.12 to 10 mm
• Cleaning: Fast maintenance with removable cassette, hopper, and push-fit rotor
• Dust Control: Integrated ring filter and 5 L collecting vessel with bayonet catch
• Safety: Quick-action door lock, safety interlock, and electric motor brake for operational safety

Function Principle:
Size reduction in the SK 300 is achieved by impact and shearing forces generated by the rapidly rotating cross beater. The airflow created via the hopper assists in material transport and discharge, while a downstream filter system separates airborne fine particles for dust-free operation.

Scope of Supply:
Includes Cross Beater Mill with cast iron 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 sizes and feeder systems are available upon request.
