SIEVES/SIFTERS/SEPARATORS/SCREENING EQUIPMENT Wagg Foods specify Mogensen
Wagg Foods, manufacturers of high quality, dry pet foods (mostly in the form of kibbles or pellets), have been specifying Mogensen vibratory screens and conveyors since 2003. The company now operates six 2-deck screens and four vibratory tubular conveyors, most of them supplied during the past two years as part of projects designed to increase output in response to lively customer demand. The screens are all used to remove coarse oversize material and fines below 3.55mm or 3.15mm depending on the product. Screen capacities are variously 10, 12 and 25tph of products with bulk densities between 350 and 400 kg/m³. All the screens are fully dust- proofed using fabric covers secured with Velcro, and fitted with flexible connectors to the inlet and outlets. The tubular conveyors are all rated at 25tph and, like the screens, are fitted with flexible connectors; the distance between inlet and outlet centres varies between 4 and 5½ metres depending on location. The Mogensen machines are all driven by Invicta rotary electric vibrators, two counter-rotating units in the case of the conveyors, and a single vibrator motor in the case of the screens. Mogensen is well known in this and other industries for its willingness to adapt and modify designs to meet customers’ specific requirements. The contractors chosen for the projects were GAME Engineering of Swinderby, Lincolnshire and Shields of Driffield, Yorkshire. Wagg Foods were known as Page Animal Feeds of Tadcaster until just over 20 years
ago, when a decision was made after 50 years of manufacturing to concentrate on specialised pet foods. At that point the company name was changed and all activities were transferred to the present purpose-built facility near Thirsk in North Yorkshire. Wagg Foods products are carefully balanced nutritionally using high-
quality ingredients to suit the needs of dogs of all types and ages, and of smaller pets such as rabbits, guinea pigs, gerbils and hamsters. Tel: +44 (0)1476 566301 Email:

High capacity centrifugal screener has cantilevered shaft for rapid cleaning, screen changes
A new Centri-Sifter™ high capacity centrifugal screener model “YOB-SS” from Kason features a cantilevered shaft with two, externally-mounted bearings between the screening chamber and motor drive (no bearing on the hinged end plate) allowing all components to slide freely from the shaft end for cleaning, screen changes, or inspection. The combination of a large diameter shaft with wide spacing between the bearings, and a
flexible shaft coupling, prevents vibration even at high speeds under heavy, imbalanced loads, according to the manufacturer. Available to USDA, FDA, BISSC, 3-A, and other US and European sanitary standards, the centrifugal screener is suitable for food, dairy, and pharmaceutical applications requiring quick, thorough wash-down, as well as industrial applications requiring frequent screen changes or material changeovers where
Kason model “YOB-SS” High Capacity Centri-Sifter features a shaft that cantilevers on two, externally-mounted bearings, allowing a baffle plate, screen cylinder, and helical paddle/feed screw assembly to slide freely from the shaft end for rapid cleaning, screen changes and inspection. (Shown with guards removed.)
cross-contamination must be prevented. It is available in configurations for gravity- fed applications or continuous operation in- line with dilute-phase pneumatic conveying systems, with screen cylinders of Nylon monofilament, woven wire, perforated plate or wedgewire screen.
As dry or moist bulk solid material is gravity- fed into the feed inlet, a feed screw redirects it into the cylindrical sifting chamber. Rotating helical paddles within the chamber accelerate the material, continuously propelling it against and through apertures in the screen. Oversized particles are ejected through the end of the screen cylinder into a discharge spout. In addition to sifting of dry materials, the screener can reduce soft agglomerates and/or dewater moist solids or slurries. Hinging open the bearing-free end plate at the
overs/discharge end of the screening chamber allows rapid removal of the unit’s internal baffle plate, screen cylinder, and helical paddle/feed screw assembly.
The company also manufactures circular vibratory screeners and circular fluid bed dryers, coolers, and moisturisers. Request details from Kason Corporation,
