AS 200 basic: favourably priced basic model.
AS 200 digit cA: powerful comfort model with touch-sensitive keypad, digital display, interval sieving.
AS 200 control: like AS 200 digit, but microprocessor-controlled, with freely selectable intervals and digital vibration amplitude setting. It can be calibrated and, for the first time, allows 100% reproducible sieving results worldwide, even if different instruments are used. The AS 200 control has an integrated interface for the evaluation software EasySieve^®. At the same time it also offers all the requirements for test materials monitoring according to ISO 9000.
AS 300 control: like AS 200 control; also suitable for sieves up to 315mm diameter and for higher loads.
AS 450 basic: budget-priced basic model for sieving up to 15kg of material.
AS 450 control: with CET technology, It is the first Sieve shaker which operates with a three-dimensional sieving motion

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
• 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.

Scope of supply: Cross Beater Mill with grinding insert, cross beater, baffle plates, filter hose, 5 l collecting vessel

Bottom sieves and base frame, please order separately.
Feeders and bottom sieves in further sizes are available on request.
