Size Reduction

October 13, 2006

Fractionizer

Designed specifically for thin, leafy materials, the Fractionizer uses a combination of teeth and interlocking grooves to cut material to a uniform size with minimal fines. It eliminates screens, attrition and high-speed impact, allowing it to deliver high particle size uniformity and control. Common applications include tea leaves, tobacco leaves, spices and more.

Lump Breaker

The lump breaker provides a simple, economical means of reducing compacted materials into smaller, granulated product required for most processing or packaging lines. It de-lumps and improves product flow for a variety of applications including sugar, salt, chemicals, cereal, kiln dust, resin, pigment, filter cake, pasta, fertilizer and more. It can be used to reduce natural agglomeration that can occur during storage/shipping or reduce material deliberately compacted in densification processing or in recycling or waste disposal applications. Features include heavy-duty single-shaft design, replaceable rotating and fixed blades, and a low profile for easy installation and maintenance.

Screen Classifying Cutter

The Model SCC-30 Screen Classifying Cutter cuts hard, soft and fibrous materials into controlled particle sizes with minimal fines at high rates. It features a patented helical rotor design with dozens of cutter blades attached to a helical array of staggered holders called “interconnected parallelograms” to continuously shear oversized materials against twin stationary bed knives. It is configured with cutter blades along the entire shaft, with no gaps between the blades, making total contact with the product. As a result, the material is cut into uniform pieces with minimal fines and imperfections in the granulate and little to no heat generation.

Roller Mill

The Raymond Roller Mill is an airswept vertical ring-roll mill that simultaneously dries, pulverizes and classifies clays, minerals and manufactured materials that are 5 or less on the Mohs scale. It provides efficient control of product size with minimal power, resulting in flexible, cost-effective production. It is available in seven sizes with ring diameters from 30 to 86 in., capacities to 80 tph, and fineness from 20 mesh to 99.99 percent passing 325 mesh. Equipment options include integral flash drying for moisture removal and static or dynamic classifiers.

Hammer Mill
Company offers the 2-Stage Reduction Swing Hammer Mill for pulverizing, crushing and disintegrating rendering by-products, wood, chemicals, minerals, garbage, fertilizer, aggregate materials, grain and more at a low cost per ton. Materials in this unit are disintegrated/shattered by revolving hammers upon entry and are further reduced by the force of impact against the heavy breaker plates in the cover. Little sizing of reduced materials is needed later. Different types of hammers are available, depending on the type of material being reduced. Many of the hammers are reversible and offer four wear surfaces to increase service life and to help lower operational costs.

Size Reduction Touch Screen Control

This new touch screen control automatically monitors multiple feeding conditions from different program settings, allowing for different automatic stop and start settings that the operator or shift supervisor can choose based on the product being fed at a particular time. This will allow the shift supervisor more control on how a machine is fed based on what product is going into the granulator. Simplified and quick access to the O&I manual and troubleshooting guides provides hassle-free maintenance, while enhanced graphics and easy-to-use help screens offer possible causes for maintenance alarms to reduce guesswork and costly downtime.

Universal Mill
In response to an increase in inquiries following the pharmaceutical industry trend toward greater containment of active materials, Kemutec has developed the Series 6H for fine grinding applications. It is designed specifically for the milling of laboratory samples and fits into a glovebox. It features an external drive arrangement, externally mounted interlock, speed indication direct from the bearing housing and gas-purge labyrinth on the bearing housing. It also has the facility for quick disconnect and body strip-down for ease of cleaning.

Heavy-Duty Granulator

The large, heavy-duty ESH-series granulator is designed for the toughest applications and can withstand the most demanding granulation tasks. The ESH line ranges from the ESH500/600 (20 × 24 in.) to the ESH800/1200 (32 × 50 in.) and is equipped with horsepower ranges from 100 through 200. With hydraulic access to the cutting chamber and screen cradle, it ensures easy cleanout and maintenance. A third bed knife or a deflector wedge can be installed in a removable adapter for more aggressive cutting, and a V-cut arrangement of the rotor knives helps keep material evenly distributed and away from the side walls.

Circulation Grinding System
The laboratory-sized Q-2 circulation grinding system is ideally suited to processing technical ceramics. This unit was customized with flame-proof electricals and sealed for grinding under inert gas. The mill is totally metal free due to a ceramic-lined grinding chamber, zirconium oxide sleeved agitator arms and a coated (Halar) premix/holding tank. The system is also equipped with a dual set of special dosing/additive tanks, making adjustments to the premix/holding tank easy and efficient.

Rubber Bale Reducer
The Vulcanator Model KM30 quickly reduces whole bales of natural and synthetic rubber to small bits with a unique low-friction cutting design. It reduces rubber dissolving time, cuts processing time and reduces costs. The 150-hp model is capable of processing larger and heavier bales up to six times faster than previous units. It features a larger throat and more-powerful cutting than prior models. The split clamshell design allows for easy maintenance of cutters and screens. Because it minimizes heat rise, it has no need for expensive cooling systems.
