are best suited for the continuous production and fast grinding of
large quantities of material. They are designed to deliver hours of low-cost,
maintenance-free operation. The basic model features a system that
does not require an expensive shaft seal.
Continuous Attritors come in two basic types, “C” and “H”
series. The “C” series runs at lower RPMs and generally uses a
larger grinding media of 5mm – 10mm diameter. The “H” series
runs at higher RPMs and utilizes smaller media of 2mm – 4mm.
Both C and H type Attritors are available in sizes ranging from
the large scale production model C/H-100 to the laboratory size
C/H-3 and C/H-5 models.
The laboratory size continuous Attritor models are designed to
reliably test and scale-up to production-size continuous Attritors.
They can also be used to produce small quantities for
developmental purposes.
A variety of accessories are available to meet different process
conditions including special models with all stainless steel
wetted parts.
