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 135°C 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.

A Vibrating Screen or Feeder is usually the heart of a production plant, its failure causes loss of production and repair may be expensive if damage has already occured. The monitoring system for Vibrating Machines detect irregular vibrations which usually remain unnoticed by maintenance personnel. The system reports them early enough to trigger preventive measures and avoid extensive damage and unscheduled downtime Monitoring functions include failure of drive shafts, overspeed, transverse vibrations, overload and resonance vibrations. Use of monitoring systems increase plant availability through avoiding unscheduled breakdowns and reducing maintenance.

The Vibro-Barsizer really works because of its effective blockage-free design principle. It separates difficult-to-screen and heavily polluted materials reliably, including bulky and irregularly shaped particles. Very effective with greasy, sticky and wet materials. Textiles, fibres and plastics in the product stream pose no problems. The linear vibration of the Vibro-Barsizer and the bars fixed at only one end help ensure a fully trouble-free separation. The bar decks are mostly arranged in multiple cascade- like steps. The material is turned around and opened up as it falls from one step to another. Pegging and blockages are positively avoided. Driven by two maintenance-free and quiet vibrator motors or Direct Force Exciters the Mogensen Vibro-Barsizer can additionally be equipped with mesh panels to meet special requirements.   Facts & Data 1. Capacity over 1000 m3/h 2. Separations between 10 mm and 150 3. Handling solids and slurries 4. Dust-tight enclosure 5. Maintenance-free operation for long-term continuous duty 6. No blockage and pegging 7. Favourable energy/capacity ratio Mogensen Bar Sizers The Mogensen Bar sizer is specially designed for coarse separations and it operates accordingly

        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.

at high capacity, free from blockage.It works without moving parts and without consuming energy. The range of separation is between 25 mm to 400 mm. Individual pieces may be 1 m in size and up to 3 t in weight. The quality of separation is astonishingly good in relation to the requirements of coarse screening. The simple and robust design ensures failure and maintenance free operation, even with difficult sticky materials contaminated with impurities. It is a simple design with creative technology. The bars diverge and are fixed at one end only. The gap opens up towards the end of the bars in the same direction as the flow of material. The material - induced bar vibration prevents blockages. The bars are made of a special steel and may be reversed in order to increase operational life. Facts & Data 1. No power supply required 2. No noise from drive or moving parts 3.
