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.

pbs0801p28c.jpgSanitary 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.

pbs0801p29a.jpgLump 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.

pbs0801p29c.jpgSeed 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.
