All the industries, be it a small portable cement mixer or large waste recycling machines, conveyors specially gravity roller conveyors are a means of fast, safe and cost effective means of feeding materials without any interruption into building mixers, food machinery or transporting heavy and fragile materials from a staging area to the actual area. There is no need for a man to manually shovel material from the supply dump into the mixer.

The simplest of all conveyors is the Gravity roller conveyors. They are typically used to Transport dry, solid items with a low centre of gravity (e.g. cannot topple) and a flat base, with no protrusions. (e.g. nothing to ‘jam’ between conveyor rollers). The items will experience a small amount of vibration as they pass from roller to roller. Gravity Conveyors are also used as accumulation conveyors for packing of the final product or accumulating materials for the next process.

In any manufacturing Industry like cooking, wrapping, annealing, container unloading, etc. it is required to feed the raw materials into a processing unit from one end and the resultant product from other. Gravity Conveyor is the best and the most cost effective solution for it. Usually Gravity Roller Conveyors link into the processing machines logic controller in order to manage inflow/outflow, and hence maximize its throughput and return on investment.

The purpose of an accumulation conveyor is to provide a ‘stop zone’ – usually at the end of the conveyor – where products literally come to a stop. This can be to facilitate packaging or handling, or merely to prevent them falling off the end of the belt and onto the floor! A short length of gravity roller conveyor makes a simple but effective accumulation zone. Products reach the end of the belt and simply slide to a halt on the roller section.

Waste recycling is one of the vital issues of our time. With pressure on availability of landfill sites, heightened environmental awareness at all tiers of government, and increased attention (and legislation) from both Westminster and Brussels; the need for efficient waste sortation and recycling has never been greater.

Gravity Conveyors can be designed, fabricated and installed as robust, heavy-duty conveyors essential for Materials Recovery Facility (MRF), facilitating the movement of waste from a loading dock, to a sortation line and on into crushing and bailing machines.

A major attraction of roller conveyors in general is the low capital cost, combined with negligible maintenance cost. Short of an all-out attack by a fork-lift truck or similar, there is very little that can go wrong with them. Individual components – such as the rollers – can be easily and cheaply replaced in the event of accidental damage.

Gravity Roller Conveyors are available at a varied price range depending upon the bed used. Plastic bed rollers are cheaper than the mild steel, galvanized steel or the stainless steel roller beds. The usage depends upon the sort of load and usage you require, and on what environment you wish to operate the machine in. (for outdoor use it is normally recommended galvanized rollers at the very least, for example).

They also come as semi-precision roller bearings depending on the load and usage. Usually, the Gravity Roller conveyors are custom designed as per the customer and industry requirement at any desired height or angle of slope. They can also be fitted with variable-height feet to allow both adjustment of overall height, as well as minor adjustments to slope angle.
