Bag Dump System with Delumper
The Delumper Bagstation is a preengineered bag dump system designed for unloading, deagglomerating, and freshening lumpy bagged solids while introducing them into a production process. The unit facilitates convenient manual opening of small- to medium-sized bags without creating a dusty environment. It incorporates a built-in delumper processor to reduce agglomerates and lumps and facilitate uniform product flow while the bags are being emptied. The system features durable stainless-steel construction, a bag grating platform, a discharge hopper, and a mounted control system.

Dual Rotor Crushers
These dual rotor crushers are used for a wide range of applications. A variety of toothed-rotor designs are available to suit specific needs. Sweeper bar–style rotors are offered for even greater versatility. Perforated sizing screens are also available in standard widths of 12 and 18 in. with standard lengths of 12, 18, 24, and 36 in. Custom sizes can be designed to meet customer requirements. All grades are available from painted carbon steel to USDA Dairy approved.

Sanitary Rotary Declumper
A low-profile rotary declumper reduces agglomerates and friable materials that are discharged from process equipment, storage vessels, and shipping containers. Material entering the square inlet is reduced in size by dual rotors with three-point, single-piece, stainless-steel breaking heads that rotate with minimum clearance inside a curved, perforated bed screen. On-size material ranging in size from 1/32 to 2½ in. in diameter exits through apertures in the bed screen. Both the rotor assembly and the bed screen can be removed rapidly for cleaning or replacement. At 11 in. high, the unit is designed to fit in restricted spaces.

Air Classifier Mill
The PPS air classifier mill incorporates an internal air-classifying wheel with an independent drive that provides precise control over particle cut-point selection. Suitable for batch processing or continuous operation, this mill serves all industries that produce fine powders where control of grinding temperature and particle-size distribution are of prime importance. The mill is available with a fully opening clamshell body design that enables easy access for rapid product change-over, inspection, cleaning, and
maintenance.

Roller Mills
Designed for the most demanding jobs and equipped with solid rolls for long life and reliability, these roller mills provide repeatability and energy savings. They are built on a strong, solid foundation and are engineered for precise control. They feature roll corrugations and roll-speed differential ratios to match all manufacturing conditions. Unique bearing slides ensure accurate, consistent production, and all machine functions adapt easily to full automation.

Lump Breakers
The Model BD-48 lump breaker features a 48 × 20-in. throat and is ideal for creating free-flowing product from a solid cake or chunky infeed material. The systems can delump solidified chemicals or be mounted beneath a silo to facilitate material flow. Constructed from either heavy carbon or stainless-steel plate, the units feature high-throughput capacity and low energy consumption. Models are available in several sizes with a variety of rotor configurations. Each unit is available with either a V-belt or gear motor drive and can be custom configured to suit specific applications or to produce the exact particle size required.

Seed Grinder
Using instantaneous grinding action, the IMD 8 chia seed Gran-U-Lizer produces a fine grind on numerous oil seeds, including chia seed, without elevating product temperatures or turning the seeds into paste. Features include water-cooling, proprietary self-cleaning teeth, and washdown construction. This technology enables oil-seed producers to achieve fine powder grinds much finer than that achieved by hammermill grinders without product stickiness and gumming. Typical capacities range from 2000 to 4000 lb/hr, depending on the grind size setting. Larger and smaller versions of the grinder are also available.

Jet Pulverizers
Micron-Master jet pulverizers are a complete line of jet energy mills that are designed to grind any type of crystalline or friable material. These advanced jet-energy mills can obtain ultrafine particle sizes in the range of 0.5 to 15 µm. To complement this technology, the company offers a custom toll processing division that specializes in the size reduction of dry powders.
