The 250 Series center-drive line of conveyors combine a unique center drive and very low profile (1.89 in.), allowing them to be used in tight quarters where conventional conveyors will not fit. With a load carrying capacity of 630 lb and speeds up to 360 ft/min, the 250 Series conveyors are ideal for many material handling applications. Belt widths ranging from 2 in. to 24 in. are available in lengths from 4 ft to 28 ft. A snap-in sealed tail assembly allows belts to be changed in less than 5 min using standard hand tools.

The compact E-Z Tec 9100 is a highly sensitive device designed for installation in free-fall or gravity-fed applications, especially where vertical space is limited. The unit detects and rejects very small ferrous, non-ferrous and stainless steel metals. To allow greater quality control, the E-Z Tec 9100 is capable of inspecting both virgin and regrind plastic pellets to ensure all are free from metal contamination. It protects all types of molding machinery, granulators, shredders and other important equipment from costly damage.

Designed for laboratory scaleup testing, the fully integrated NIR System incorporates near-infrared (NIR) spectroscopy with 21CFR Part 11-compliant software to provide immediate and reliable data that are remotely transferred to a personal computer. The combination of a robust vibration-resistant design, moderate bin rotation speeds and easy-to-use software ensures 100% accurate scaleup results. Effective bin-blending volumes range from 20% to 85%. The system is fully enclosed and eliminates physical sampling requirements.

These graters/shredders are able to shred, grate or granulate solid, dry or moist materials. Typical applications include size reduction and granulation after high-shear mixing, rework of tablet press material, and material sizing after bed or tray drying. The PGS300 is the most powerful unit, with throughput rates between 1,000 and 4,000 kg/h. The units include easily interchangeable cylinders, 360-deg apertures for optimum product flow and a variety of cylinder mesh sizes to fit most applications.

This inline pneumatic batching system allows simultaneous weigh batching of major ingredients supplied in bulk bags and manual dumping of pre-weighed minor ingredients, and blending of the material, while a subsequent batch is accumulated. Each of the bulk bag dischargers is mounted on load cells, allowing loss-of-weight batching from either or both bulk bags.

The self-contained PortoVeyor bulk bag unloaders keep plants productive when bulk truck or rail delivery is interrupted. The skid-mounted PortoVeyors are ruggedly built and can be customized with optional hoists and lifting frames to support and unload all sizes and styles of bulk bags without slippage or spills. They not only open bags and convey their contents, but they also clean up nuisance dust. Bulk bags empty into a receiving hopper, which is fitted with a motor-driven rotary valve that meters contents into the conveying lines.

Available in both infi- nite-position and quick-lock models, the Vortex stainlesssteel iris valve may be configured to meet a variety of application requirements. These can include: Type 304 stainless steel body with Type 304 stainless material contact; Type 304 stainless steel body with Type 316L stainless material contact; and Type 316L body with Type 316L stainless material contact. The patent-pending valve is precisionmachined to ensure its components actuate smoothly and the flange connections match and seal properly. Sizes range from 4-in to 15-in. diameters.

Designed to meet high-capacity sifting for bulk load-in/load-out and larger process applications, the Rotex Centrifugal Sifter can handle a wide variety of powders, granules, agglomerates and other free-flowing materials. Processed particles ranging in size from 1/4 in. to 44 µm (325 mesh) are scalped with ease. The combination of high centrifugal force and blade spreading action reduces binding problems, even when handling materials that tend to flake or agglomerate due to fat or moisture content.

Designed for vacuum operations, these new Sanitary Ribbon Blenders are manufactured in Type 316-stainless steel and are polished to enable easy cleaning between batches. Agitators and shaft assemblies are designed and constructed with generous radii and smooth-weld finishes. Shaft-seal rings are readily accessible and easily removable to permit cleaning of all product zone surfaces. These blenders include special cover openings, ports for viewing, jackets for heating or cooling, complete control systems and more.

Mass Flow Feeder The Pebco Mass Flow Feeder is a controllable high-capacity gravity feeder for relatively coarse granular materials. The feeder consists of a mass flow hopper with two movable sides that control the discharge rate. The flowrate is a function of the discharge opening width and the slope of the blades. The minimum flowrate is limited by the opening width at which the material arches across the opening. Turndown rates of 10 to 1 can normally be expected. The units generally handle flowrates from a single discharge point from 1,000 ton/h to 10,000 ton/h.
