Specifications

The Vertical Disintegrator is currently available in three models (RD12, RD18 and RD24) and is typically built from stainless steel and carbon. The equipment can easily be configured with a wide range of motor, perforated screen and rotor sizes to suit the demands of the material being processed. Typical throughput rates are determined by factors including the chosen configuration of the equipment and the material itself.

The smallest version (RD12) includes a 300mm diameter rotor and power options up to 30kw. Typically, this could process a material such as Mica flake slurry at a rate of two tonnes per hour.

At the other end of the scale, the RD24 is almost twice the size of the RD12 and comes with up to a 710mm diameter rotor and up to a 150kw drive. With a 600mm diameter rotor, 90kw drive and a perforated screen with 6mm holes, a challenging raw material such as seaweed could be processed at a rate of approximately 9 tonnes per hour using the Vertical Disintegrator.

The Vertical Disintegrator is easy to maintain and a CIP system can be integrated to make cleaning an easy and efficient process.
Hosokawa Micron Ltd has wide-ranging experience of designing, engineering and manufacturing bespoke Vertical Disintegrators that comply to the specific requirements of our customers. Along with single units, we are also able to produce multiple Vertical Disintegrators for customers as part of the same order, often manufacturing two identical pieces for delivery at the same time.

Used For

The Vertical Disintegrator is an impact mill used for grinding and classifying small to medium-sized raw materials, including difficult-to-process products such as those with a high fat or moisture content. Its ability to separate impure and pure material (of variable wetness and fineness levels), makes it a very practical option for manufacturing pharmaceuticals, composite materials, wallpaper and paper products, dietary supplements, chocolate and dyes, as well as processing fruits, vegetables, frozen meat, resin, fishmeal, tallow, seaweed, barley, mica flakes and petrochemicals.

How Does It Work

The Vertical Disintegrator is designed to efficiently process both straightforward and more challenging raw materials, including those with high fat or moisture content or materials likely to produce waste, such as grains or wood.

Material is fed into the machine from the top via a screw feeder, entering the processing chamber where a high-speed rotor and strategically arranged hammers grind and disperse it. A 360° perforated screen surrounds the chamber, ensuring consistent size reduction. The top and bottom hammers control retention time, while the mid-section hammers manage dispersion and grinding.

Once the material is reduced to the required size, it passes through the perforated screen and exits through the main discharge outlet, typically collected by suction. Any impure or rejected material is continuously discharged via an optional secondary outlet. The screen’s uniform perforations, available in various sizes, help ensure consistent particle distribution while limiting temperature rise during processing.
