The various versions of this type of Vibro Screens permit its use for wet and dry screening, coarse and fine separations and are widely used in steel mills, mineral beneficiation plants, chemical, mining, food and fertilizer industries, coal preparation plants and many others.

The main characteristic is OPERATIONAL RELIABILITY to suit the widest possible range of precise requirements.

The box shaped screen body can be fitted with almost any type of screen mat - of steel, rubber or plastic with provision for transverse, plane or longitudinal tensioning.

The steep angle of throw prevents mesh blinding, which permits maximum screening efficiency. The operating speed range normally varies between 1000 - 1500 rpm.

The screening machine is driven directly through a cardan shaft. The vibrating element is a through shaft, mounted in the two screen webs and fitted with unbalance segments. All clamping parts and screen mats are easily changed.

The design features high acceleration on the deck surface which permits handling of difficult-to-screen materials. The centrifugal force exciter unit is mounted on special vibration duty bearings that are grease lubricated and require minimum maintenance.

Available in single and double deck versions, the size range includes machines up to 2.5 m wide x 6.5 m long. Capacity range up to 1200 tons per hour depending upon separation size and material characteristics.

The Flip Flop screens offers a totally new solution for extremely difficult-to-screen materials with excellent screening efficiency in smaller aperture applications where conventional screens suffer from blinding and pegging.

The Flip-Flop Screening Machine generates, through a mechanism, a system of dual control whereby a high acceleration is transmitted to the panels of the Screen Mats of the order of around 40-50g. The eccentric rotor mechanism generates a continuous and flexible movement of the elastic Screen Mats, with the panels alternatively stretched and relaxed.

The high acceleration completely loosens up the damp sticky material mass, resulting in rapid stratification of the feed material and high percentage of fines quickly move down to the surface of the Screen Deck and are screened out.

Soft rubber mounting blocks isolate the majority of the dynamic loads of the oscillating mechanism.

The flexible screen deck are manufactured from Polyurethane or Rubber having square or slotted aperture openings in various sizes which are selected depending upon material to be screened.

Machiene Sizes upto2.5m wide and 7.9m long.

The complete range of Mogensen Sizers are offered including specialised accessories.Also included in the range are Flip Flop Screening Machines as well as the new Sizer 2000 especially suitable for very fine screening applications.Mogensen screening machines are offered on a made-to-measure basis offering intelligent solutions.The product range offers a very wide selection for fine screening - from approximately 100 mic. and for coarse separations up to 5 mm.

3 to 6 progressively inclined screen decks with progressively finer mesh apertures are arranged in a functional and compact manner in the vibrating screen frame. Because of the inclination in the meshes the screening effect and thereby the separation size are appreciably smaller than the apertures in the mesh panels. This drastically reduces the risk of pegging and increases the capacity considerably because the coarse-mesh system induces a dispersed material flow without the build-up of a bed of material. Residence time in the machine is short. The processed material falls vertically and rapidly through the Sizer whereby coarse particles are removed early in the screening process from the required product stream. Wear and tear on the finer lower decks is greatly reduced.

The Spiralling Belt Elevator moves bulk solids continuously through horizontal and vertical stretches with no points of transfer.

Motor speed, material feed, and straight belt run are monitored by safety devices. The elevator is fed horizontally by a continuous conveyor. In the area of transfer, any fine material particles adhering to the belt drop into a scraper conveyor and are fed back as spillage to the main flow by a circuit conveyor.

The vertical handling section consists of the rubber belt with corrugated side walls and "flights'. This vertical section of the elevator can be slewed in the direction of discharge. Slewing through 135C to either side is possible while moving. A control unit ensures accurate positioning of the belt to the selected point of discharge. The material is discharged from the upper horizontal section.

Application

The Spiralling Belt Elevator can be used wherever fine-to-coarse-grained bulk solids require to be handled, horizontally and vertically, in a very confined space.

The Scooping Belt Conveyor moves bulk solids continuously on level and inclined stretches. The webs, or flights, of the corrugated and belt scoop up the material and also prevent the flow-back of fluidising powdered material.

The totally enclosed construction ensures that there is no spillage. Material adhering to the belt and moved beyond the point of discharge, immediately returned by the partitions to the feed side and received back by the upper belt.

The housing of the return, and take-up units designed as a scooping trough, serves this purpose.

Application

The Scooping Belt Conveyor is preferably used to handle wet ash. lime, cement, gypsum, ground lime, wood chips, or similar, difficult-to-handle material.

These machines are incorporated in an automatic and dustless system for grinding and classifying non- metallic minerals and dry chemicals to a high degree of product uniformity. With integral cone and whizzer separators, product finenesses from 800 to 35 microns are achieved. The mills are airswept with a classifier fitted directly above the grinding chamber to give continuous classification of the ground material. They are ideal for economic production of very fine powders, and can handle difficult, sticky materials.
