Currently the belt is manufactured in two (2) sizes:
- 800 Series (800mm wide)
- 1400 Series (1400mm wide)
The Belts contains a two (2) ply Fibre reinforcement and factory molded triangular wedge profiles on both edges. (There is no steel cord or cable in our system) as the steel tends to ‘delaminate’ from the rubber, causing catastrophic failure.
The belt is available in:
- Abrasive Resistant Rubber (ARR)
- Heat Resistant Rubber (HRR)
- Chemical Resistant Rubber (CRR)
- Fire Resistant Rubber (FRAS)
- Minimum diameters are also applicable to Bend and Tensioning Pulleys.
- Space allowance for carrying and return belts are approximately as follows: 800mm belt -900 width x 750 depth and 1400mm belt -900 width x 1050 depth.
The above technical information is intended as a guide for engineers to carry out preliminary study to see if the Premron EBS is for their requirements. Please feel free to refer any technical queries not covered above, to the Premron EBS Team. We will also assist without obligation, in the preparation of any layouts of existing or new plants to determine suitability.
Idler Stations are made from a solid, low cost Housing that mounts a pair of standard Conveyor Idler Rollers (cantilever design). The Idler Rollers are fitted with single row deep groove precision Ball Bearing that are ‘closed for life’ (no maintenance) and carries a B10 Bearing Life. The Inside Rollers fitted on a curve are manufactured from high grade HDPE giving better Belt wear on corners. Each Idler Station is located between 800-1200mm apart and may carry an addition Idler Roller mounted to the top of the belt wedge profile to ensure correct Belt engagement.
The System has multi drives located at calculated positions along the Belt. They are generally 1.0-1.5kw Drives and are set in matched pairs on either side of the Belt. They are mounted from a low cost, light weight Drive Housing, which includes pre-set spring tensions that apply even pressure to the Drive Wheels that run on the belt wedge profile. The Drives are controlled via Inverters thru a PLC system that evenly load share all drives across the Belt. Some Drives are fitted with a Brake to ensure fast stoppage in an Emergency and/or Anti- Run Back.
The system contains a Head Pulley (Discharge) and Tail Pulley (Take-Up) which is similar design to a standard Trough Belt Conveyor with the difference being a tapered end section to allow the belt wedge profile to locate. Due to the low belt tensions the Pulleys are light weight, contain smaller bearings and low cost. The Head Pulley is mounted horizontal while the Tail Pulley mounted vertically and contains the gravity Take- Up Trolley/Counter Weight Assembly. A Belt Cleaner can be easily mounted on the Head Pulley, though it is not important as product carryover does not effect the performance of the Belt, but may effect the thru put of the product (tph), in certain applications and medium.
The Belt is loaded via a ‘dust free’ Loading Station. The System gently opens the Conveyor Belt by splitting the wedge profile and carrying each wedge separately apart to an open position via UHMW Slides. The Product is loaded onto the Belt via a fixed displacement Feed System (Chain/Screw Conveyor; Rotary Valve or similar). The lower part of the Belt is supported via Impact Rollers and then carried forward where the wedge profile is returned to its closed ‘sealed’ position. The Load Station is fitted with a Level Detection Sensor to ensure the Belt cannot be over loaded.
The Conveyor System is installed with a series of ‘Safety-Pull Wires’ for personnel protection. At ground level the System can be fully Guarded and Interlocked according to the site requirements. Rip Belt Sensors are also placed along the Belt to detect unforeseen occurrences. On the Pulley we can monitor Belt Speed via Rotation Sensors. A inline Weigh Scale System can also be fitted. As the System is low maintenance we don’t require full personnel access along the Belt. This can be done cost effectively and safely via a ‘elevated’ work platforms all components above ground level are ‘man handable’ (low mass).
