General Specification: Modular Belt Conveyor

Chassis

The chassis consists of folded and fabricated mild steel sections that are bolted together. Due to modularisation the conveyor can easily extended or shortened should it be required. All conveyors mounted by means of bolted rotational brackets. Standard widths of conveyors supplied are 600mm, 800mm, 1000mm, 1200mm, 1500mm and 1800mm. Profile of the section creates a trough on the belt to contain the material, but conveyor is designed so that extension hoppers can be easily bolted on. A big advantage to this type of conveyor is that they can be easily reconfigured both in length and width. The design can easily have lower sides that are enclosed which it makes it ideal for picking conveyors.

Head Pulley

Pulleys are of closed end fabricated mild steel construction; shell surface shall be crowned and lagged with a 12mm diamond lagging. Shafts shall be taper-locked or squeeze locked in to position so that the shaft can be easily replaced and also prevent heat stresses from causing premature failure on the shaft when shock loaded. The drum shall have a standard external diameter of 219mm with a 9mm wall thickness unless larger pulleys are required for thicker belts or traction. The shaft has a diameter of 50mm. In the case of the drum being placed beneath a magnet the drum will be manufactured from non-magnetic stainless steel otherwise the drum will be fabricated from mild steel.

Belt

3 ply synthetic having an EP500 value with rubber covers of 4mm on face and 2mm on underside. Should the conveyor inclination be above the limits of a flat belt a chevron belt will be supplied with a minimum of a 16mm cleat or a low profile v6 pattern if the rolling fraction is not a major issue.

Impact Plates

Impact plates offer more support for the belt at the loading point to increase puncture resistance due to the fact that the entire belt is supported on the low friction heavy duty plastic. Impact plates rather than impact bars limit the damage inflicted by rebar puncturing the belt and causing major rips.

Drive Motor

All motor gearboxes are supplied by SEW. Through shaft mounted reduction gearbox which will have the motor fitted to it. Linear belt speeds between 1m/s and 1.5m/s as standard except on quality control conveyors which run at 0.5m/s. ideally a preferred supplier of motors and gearboxes would be chosen so that standardisation between conveyors becomes more common but a lot of manufacturers operate off similar specifications so the most important consideration is local support.

Tail Pulley

Drums are of closed end fabricated steel construction, drum surface shall be crowned Shafts shall be taper-locked or squeeze locked in to position so that the shaft can be easily replaced and also prevent heat stresses from causing premature failure on the shaft when shock loaded. The drum shall have a standard external diameter of 320.9mm with a 9mm wall thickness. The shaft should have diameter of 50mm as standard to minimise spare parts and the shaft should run through the pulley.

Tension Device

Screw tension bolts are fitted to tension tail shaft bearings to enable correct tension to be maintained in belt.

Return Rollers

114mm diameter as standard with a minimum 20mm diameter shaft. Return roller include rubber anti clogging disks when conveying sticky materials. Return Idlers to be positioned at no more than 2.5m centres.

Centre Rollers

76mm diameter as standard on conveyor 1200mm or under. The centre idler will have lifetime grease packed bearings, fully welded shells, and high-performance seals. All idlers will be placed at no more than 1000mm centres.

Skirting

Where required conveyor skirts are 150mm high as standard but can be extended up to 600mm should it be required. Skirting rubber is supplied as standard to seal between the belt and the skirt in order to keep spillage on the belt to a minimum. Where magnets are close to the conveyor the skirt should be manufactured for non-magnetic stainless steel.

Lubrication

All conveyors are piped with heavy duty hydraulic hosing outside the safety guarding to allow for easy maintenance of the four pillow block bearings.

Bearings

Pillow block bearings as standard on the head drum while take up bearings are used on the tail pulley. Both types of bearing should be taper locked to the shaft.

Belt joint

Belt to be provided with a hot vulcanized joint where possible.

Guards

All guards will be supplied in accordance with Australian standards.

Paint and Protection

All mild steel is coated with one coat of primer and one coat of top coat paint. The colour is at the customer’s discretion.

Internal Scraper

V-Plough scraper to prevent anything getting between the belt and the tail drum and causing damage to the belt.

Belt Scraper

Optional mechanically tensioned by means of a torsion bar fitted just behind the head drum. The blade renews its edge as it wears. The blade forms a new shearing edge once wear reaches each new faceted blade section, resulting in continuous cleaning efficiency throughout the life of the blade.
