Retsch Rotor Beater Mill SR 300 <25mm, 3.000-10.000 min⁻¹, 220-240V, 50/60 Hz, Stainless Steel

The Retsch Rotor Beater Mill SR 300 Stainless Steel is designed for rapid and reliable size reduction and deagglomeration of bulk materials in both laboratory and small-scale production environments. Engineered with a robust stainless steel grinding chamber, feed hopper, inlet, and outlet, the SR 300 is ideal for processing large sample volumes with minimal contamination risk. Its adjustable speed range from 3000 to 10000 min⁻¹ allows the mill to adapt to diverse material properties and application needs.

Key Features:

• Brand: Retsch
• Material: Stainless steel (grinding chamber, inlet, outlet, and hopper)
• Feed Size: Up to 25 mm
• Speed: Adjustable from 3000 to 10000 min⁻¹
• Voltage/Frequency: 220–240 V, 50/60 Hz
• Application: Suitable for sample preparation in chemistry, agriculture, pharmaceuticals, food, and materials science
• Grinding Inserts: Optional 180° insert for hard, brittle materials and distance rotor for heat-sensitive samples
• Final Fineness: Controlled by bottom sieves with aperture sizes from 0.08 to 10 mm
• Ease of Cleaning: Removable cassette, hopper, and push-fit rotor
• Collection System: Ring filter and 5 L collecting vessel with dust-tight bayonet catch
• Safety Features: Quick-action door lock, motor brake (< 0.5 s), splashback guard, inlet/outlet safety barriers, and safety switch

Function Principle:
Size reduction and deagglomeration in the SR 300 are achieved through impact and shear effects. The rotor draws in air and accelerates sample discharge, while fine particles are collected via a downstream filter system. The secure door lock allows fast and safe access to internal components for cleaning and maintenance.

Scope of Supply:
Includes the rotor beater mill, stainless steel rotor, 5 L collecting vessel, and filter hose.

Note: Base frame, sieves, and sieve frames must be ordered separately. Additional sieve and rotor options available upon request.
