RETSCH ROTOR BEATER MILL SR 300

RETSCH ROTOR BEATER MILL SR 300
Saringan Mesh

Deskripsi produk
The Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction. It can process dry, soft, medium-hard, organic and inorganic substances. For increased sample discharge and for processing heat-sensitive samples, an optionally available cyclone unit can be used instead of the gravity outlet.
PRODUCT ADVANTAGES
wide range of accessories including various feeding systems, rotors and sieves
defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm
optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
gravity outlet with 5l or 30 L collecting vessel for batchwise collection of larger sample quantities
optionally available cyclone unit with 0.25 - 0.5 - 1 - 2 - 5 or 30 liters collecting vessel
optional distance rotor to reduce frictional heat
adjustable speed for different applications
removable hopper for easy cleaning
easy cleaning thanks to exchangeable push-fit grinding insert, rotor and cassette
central locking device
grinding chamber, feed hopper and material inlet and outlet made of stainless steel
electric engine brake
APPLICATION EXAMPLES

FUNCTIONAL PRINCIPLE

Size reduction and deagglomeration in the SR 300 are achieved by impact and shear effects. The feed material passes from the hopper into the center of the grinding chamber where it is crushed between the rotor, sieve and grinding inserts. As soon as the material is smaller than the aperture size of the sieve it enters the collecting receptacle through the gravity outlet. The airborne fine fraction is separated off by a downstream filter system. The optionally available cyclone separator ensures a cooling of the sample material and the cutting tools and improves the discharge of the sample from the grinding chamber. The quick-acting door lock ensures easy access to the grinding chamber for quick cleaning. With their safety switch, splashback and access barrier in the inlet and outlet areas, Rotor Beater Mills offer the highest degree of operating safety.
