Introducing the Premron
Enclosed Belt System
Your environmentally friendly conveyor solution.
Enclosing the payload and ensuring dust free conveying.
The Premron EBS Closed Conveyor System uses a rubber 2ply reinforced belt that is formed not as a trough, but as an enclosed teardrop or pouch, which is supported between a pair of idlers, enclosing the ‘pay load’ and ensuring ‘Dust Free’ conveying.
Instead of having a single high cost/high powered drive, the system has multi-low powered, low cost, drives that are controlled and strategically placed along the Belt, resulting in very low belt tensions.
Ability to negotiate tight turns at a small radius.
No costly transfer towers required for change in conveyor direction, which also cuts out dust/spillage issues at transfer stations.
Conveyor can travel up steep inclines (36degree).
Payload is totally
enclosed ensuring dust free conveying; no spillage, odour control and ingress of rain resulting in environmentally friendly conveying.
The industry advantages for our enclosed belt conveyor.
Built to handle the demands and conditions of the resource sector, the Premron EBS delivers a cost effective, safe, environmentally friendly material handling solution.
The ability to negotiate tight turns at a small radius.
No costly transfer towers required for change in conveyor direction, which also cuts out dust/spillage issues at transfer stations.
Ability to run the conveyor around existing plant and equipment on site in various orientations (supported or suspended).
Conveyor can travel up steep inclines (36degree)

Payload is totally enclosed ensuring dust free conveying; no spillage, odour control (hazardous product containment) and ingress of rain which alleviates ENVIRONMENTALLY FRIENDLY CONVEYING.
Carry and return strands of belt can be loaded in both directions and can follow different routes.
Light weight structures (minimal costs) (average weight = 200kg/m).
Ability to be mounted off existing structures.
Minimal civil infrastructure (if any) / None of the ‘traditional’ heavy drive footings required.
Very small gravity take-up assemblies required (nominally 300kg mass)
Self tracking and minimal belt stretch, reduced wear and fatigue; all attributes that reduce belt maintenance.
Ease of conveyor extension or re-directional change (can be skid mounted).
Ability for low cost belt extension or re-routing via a simple hot vulcanise splice similar to a normal traditional trough belt splice.
Low capital cost of system as well as low stores inventory required for the conveyor (all components are standard).
Technical Specifications
-
Currently the belt is manufactured in two (2) sizes:
1000 Series (1000mm 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)
Food Grade Belt
Fire Resistant/ Anti Static (FRAS)
-
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.
-
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 1.0-3.5kw 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 provide redundancy, so that if a drive fails the conveyor can continue to operate.
-
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).
-
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.
Premron EBS have a design and manufacturing facility in Gladstone, Qld, Australia and can offer a full turn-key project to its clients.
We are happy to assist without obligation, in the preparation of any layouts of existing or new plants to determine suitability.
