Gravity Roller Conveyor

The simplest of all conveyors is the Gravity roller conveyors. An unpowered bed of rollers, often sloped, which allows goods to be pushed down the line. They are typically used to Transport dry, solid items with a low centre of gravity and a flat base. They can be set at a slight incline or horizontal, to allow staff to ‘freewheel’ the products along the line. Gravity conveyors are also very useful as an adjunct to powered conveyor systems, providing a packing or accumulation area.

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.

Reinforced rubber belting:

A sandwich of rubber and layers of fabric/plastic reinforcing mesh, these are the workhorse of the heavy conveyor industry. They are typically used on exterior conveoyrs such as waste recycling or aggregate handling.

PVC:

The material of choice for general indoor lightweight conveyors, this material is very popular in general packaging and warehousing industries

PU:

Polyurethane is a very strong, dirt-resistant material. Similar in appearance to PVC, it is favoured in the food handling/preparation industries for its hygiene properties. It can be produced with an anti-bacterial upper surface.

Steel Wire Mesh:

Another material very popular in the food industry, this belt allows air to circulate freely around its load, as well as allowing liquids to drain away.

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.

Many Conveyor suppliers manufacture Gravity roller conveyor beds made from plastic, mild steel, galvanized steel, or stainless steel rollers depending on 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 offer a choice of semi-precision or fully-precision roller bearings, again depending on anticipated load and usage. Gravity Roller Conveyors can be custom-built for each customer, and hence can be “pre-set” 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.
