Vibratory Disc Mill RS 300 XL

Close

Language:


The Vibratory Disc Mill RS 300 XL is suitable for the extremely quick, loss-free and reproducible grinding of medium-hard, brittle and fibrous materials to analytical fineness. It is possible to process 1, 2, 3 or 4 samples simultaneously. Thanks to the robust universal drive shaft, which sets the grinding jar into a 3-D motion, this mill accepts grinding set weights of up to 30 kg. The closed grinding system guarantees complete processing of the sample.

Just like the RS 200, the RS 300 XL with its robust design has proven to be ideally suitable for applications in geology, mineralogy, metallurgy, as well as in the building materials sector (cement) and in power plants.

Due to the high end fineness and speed the RETSCH Vibratory Disc Mills are the perfect choice when it comes to preparing samples for spectral analysis.

Exemplos de aplicação

óxidos metálicos, cerâmica, cimento, clínquer de cimento, coal, componentes eletrônicos, concreto, coque, coríndon, escória, minérios, minerais, partes de plantas, silicatos, solos, vidro, ...

Princípio de funcionamento

The vibratory disc mill comminutes by impact and friction. The grinding set is firmly attached to the vibration plate with a pneumatic quick clamping device. The plate with the grinding set is subjected to 3-D vibrations.

The sample is crushed by extreme pressure, impact and friction generated by centrifugal forces acting on the grinding rings in the dish.The vibrations are produced by a frequency controlled 2.2 kW 3-phase motor.
