Size Reduction

January 4, 2012

Powerful, Versatile Crusher
The Delumper 1075 LP crusher reduces hard or soft, heat-sensitive, sticky, or wet agglomerates and lumps at high volume without degrading the material or causing rise in temperature. The unit’s low-friction cutting action is ideal for large quantities of sludge cake, agglomerated chemicals, plastics, fats, waxes, or solid waste. The crusher employs extended cutting teeth that rotate completely through a heavy bar cage, self-clearing the slots with each rotation. Each tooth is built for precise balance, interchangeability, and smooth operation. Output sizes are adjustable by changing the speed or the comb. The size of the material handled can be as large as the throat opening. The unit is provided with a one-piece seamless uni-body housing.

Vibro-Energy Grinding Mills
These vibro-energy grinding mills are a versatile line of mills available for fast, low-cost particle size reduction to sub-micron range. Vibro-energy grinding action achieves higher output per input horsepower, and precise control of size and distribution. Product contamination from media and lining wear is virtually eliminated. Maintenance costs are low because of the few moving parts and replaceable linings made of abrasion-resistant metal, ceramic, or elastomers. The unique vibratory motion, coupled with the use of cylindrical media, allows a dense packing of the media bed, assuring maximum media surface contact and minimum void area when operated under a low-energy condition. Feed materials as large as 300 microns can be reduced to sub-micron sizes. Sweco, Florence, KY 859-283-4572 www.sweco.com

Triangular Blade Lump Breaker
The Triskelion lump breaker is composed of a number of rotating triangular blades that intermesh with stationary blades. The triangular blades capture the input material, force it through the lump breaker, and roughly size the output into relatively uniform pieces of 3/4 in. or less by the spacing of the blades. The unit is effective for breaking press cake, chunks, slabs, and sheets of wet, dry, sticky, hard, or soft materials. Construction is mild or stainless steel, with other materials available. Units are available in capacities from a few pounds to several thousand pounds per hour. Special features like rod fingers instead of blades, gas-tight construction, and sanitary and high-temperature construction are available. Wyssmont Company, Inc., Ft. Lee, NJ 201-947-4600 www.wyssmont.com

Sanitary Lump Breaker
with Side Removal Screens
The model RDC1515-SS sanitary lump breaker features side removal bed screens for rapid, thorough washdown. Materials entering the 15-in. square inlet are reduced in size by dual rotors with three-point, single-piece, stainless steel breaking heads rotating with minimum clearance inside a curved, perforated bed screen. On-size material exits through apertures in twin bed screens ranging from 1/32 to 2-1/2 in. in diameter. The low-profile unit is designed to fit in restricted spaces between bulk storage, processing, and packaging equipment. Whereas conventional units must generally be unbolted from upstream and downstream equipment to access bottom-mounted bed screens, the new unit with side-removal bed screens can remain in place, allowing thorough sanitizing in a fraction of the time. Constructed of stainless steel and finished to sanitary standards, the unit is suitable for food, dairy, and pharmaceutical applications as well as industrial applications where cross-contamination is a concern.

Single and Dual Rotor Crushers
Single and dual rotor crushers have been successfully applied to complement pneumatic conveying and bulk handling system installations in the dairy, food, chemical, pharmaceutical, and agricultural industries. Many times an application’s product characteristics or process can change, producing lumps that are larger than the original material. If these lumps are not pre-conditioned through size reduction equipment like a crusher, these lumps can drop out of the air stream, build up, and clog the horizontal conveying lines. The proper selection of the size reduction equipment to pre-condition the material prior to the pneumatic conveying system will ensure that you will not have any problems with your conveying performance caused by plugged conveying lines.

Lump Reducer
The LumpMaster reduces lumps and agglomerations, producing a small, more uniform product for further material handling applications. Heavy-duty, yet compact in design, the LumpMaster will fit into most processes. Two gear-driven, counter-rotating finger shafts and replaceable side combs are used to eliminate lumps. The unit is available in carbon steel, as well as 304 and 316 stainless steel, and comes with a performance guarantee. Hapman, Kalamazoo, MI 800-427-6260 www.hapman.com

Classifier Mills
The CLM series classifier mills are a combination of two stages of closed-circuit grinding and air classification all in one unit. Materials that are difficult to grind and those that require a finer grind and/or a narrower particle distribution curve than is practical to produce in a fine grinder often require the capabilities of the CLM classifier mill. The built-in classifier, to separate part of the grinding rotor designed especially to handle these more difficult items to grind, rejects large particles not completely ground in the first stage of this grinder. They are reground and then reclassified. Prater-Sterling, Bolingbrook, IL 630-759-9595 www.prater-sterling.com
