Wet Grinding Production
How Continuous Attritors Work
The continuous Attritor is a compact vertical design suitable for continuous production of large quantities of materials. Advantages of using a continuous Attritor include continuous large production, fastest grinding and processing, excellent temperature control, simple and safe operation, and low power consumption.

Advantages of Using a Continuous Attritor:
• Fastest grinding and processing
• Excellent temperature control
• Simple and safe to operate
• Low maintenance and power consumption
Common Applications for Attritors:
• Paints, toners, inks
• Food products
• Chocolate, confectionery
• Metal oxides
• Agricultural flowables
Continuous Attritors 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.

(DIMENSIONS AND WEIGHTS ARE APPROXIMATE)
Equipment can be built to CE specifications, if required.
- All models can be equipped with a torque meter to precisely measure energy expended in the grinding chamber.
- Stationary arms can optionally be fitted into the tank wall in configurations best suited for your specific application. These arms are removable/interchangeable.
- Baffles and special linings can be fitted or coated on the tank walls to increase the life of the tank in applications such as power plants and mining when maintenance must be kept to a minimum.
- Variable speed drive motor systems.
- Cover and shaft seals for grinding in a closed (pressurized) system.
