554 5. Sample preparation Grinding/Mills GENERAL CATALOGUE EDITION 20 E & OE. Cross beater mill SK 300 The cross beater mill SK 300 is used for batch-wise or continuous preliminary and fine size reduction. This robust mill is suited for laboratories as well as for the rough conditions of a production environment. Thanks to the powerful drive and rotor speed up to 4000 rpm it is often possible to achieve a final fineness <100 microns in one process. Features: - High throughput for batch-wise size reduction of large sample volumes - Suitable for feed sizes up to 25 mm - Adjustable speed from 2000 to 4000 rpm - Defined final fineness due to bottom sieves with aperture sizes from 0.12 to 10 mm - Rapid cleaning thanks to easily removable cassette, hopper and push fit rotor - Ring filter and collecting vessel with convenient, dust-tight bayonet catch - Quick-action door lock safety lock and electric brake Function principle: Size reduction in the SK 300 takes place by impact and shearing effects. The air drawn in through the hopper by the cross beater accelerates the discharge of the ground material. The airborne fine fraction is separated off by a downstream filter system. Supplied with: Cross Beater Mill with grinding insert, cross beater, baffle plates, filter hose and 5l collecting vessel. Bottom sieves and base frame, please order separately. Feeders and bottom sieves in furrther sizes are available on request. 1 Retsch Specifications Feed size: up to 25 mm Final fineness: approx. 0.1 mm Speed range: 2000 to 4000 rpm Dimensions (W x D x H) with base frame: 600 x 700 x 1200 mm Weight: approx. 57 kg Power supply: 220-240 V, 50/60 Hz Type PK Cat.
