Conveyor technology and systems – optional accessories and equipment

If there is enough space under the belt, a lower belt scraper is always a good choice. It is mounted in such a way that it does not come into contact with the material flow and is therefore also an ideal choice if the conveyor belt is installed on an incline. The lower belt scraper is made of tungsten carbide (TC) and suffers from minimal wear and tear.

The head scraper is used when there is limited space. It is attached to the "head" of the conveyor belt and is made of polyurethane (PU). The GÜNTHER head scraper is equipped with a lever system by which the scraper can be swung away and cleaned. In addition, the contact pressure of the scraper on the belt can be adjusted and regulated. The scraper is designed in such a way that it remains serviceable even when worn and there is no reduction in cleaning quality.

A knocking roller can be useful for profiled belts and should be considered if other scraper systems are not fully effective. The expansion and compression of the belt's surface before the change in direction causes the attached material to be released from the belt's surface.

The drum scraper is attached to the drum inside the conveyor belt. It keeps both the inside of the belt and the drum free of contaminants and thereby prevents damage to the belt.

This type of scraper is installed within the belt system . It prevents contaminants that accidentally work their way into the housing from getting in between the belt and the drum, thereby damaging the belt. The plough scraper is self-adjusting due to its own weight.

Hoods/covers offer protection against wind, weather and smells. They are often also used when material is being transported from one part of a building to another. Depending on customer requirements, covers are attached to the conveyor belts to protect the belt and material from adverse weather. In windy conditions, material can be blown off the belt and fly away or be spread around the site. When it snows, material can slip, which is a major problem, particularly when the belt is on an incline.

Sheet metal plates not only protect against accidents; they also prevent spillage from falling into the system and on to the ground.

As well as preventing tampering, grills have the advantage that you can still see inside and, if a problem occurs, quickly locate the affected area.

The belt supports are made from galvanised steel, which are installed at 6-metre intervals. If this is not structurally possible, there is the option for GÜNTHER to reinforce the belt to allow for longer distances between the belt supports.

Sealed transfer systems are closed on all sides and are mainly used for dusty materials.

Unsealed transfer systems are constraints that prevent material from falling off the conveyor when being transferred from one belt to the next or to another piece of equipment.

Belt scales are installed in conveyors to determine mass flow. A rolling system measures the pressure on the belt and the belt's speed and uses this information to calculate the amount of material.

The emergency stop device is designed for emergency situations, for example if an employee is pulled into the mechanism, a fire breaks out or material starts to pile up due to a blockage in the system. An emergency stop button or the pull cord on the belt can then be activated. The "two-channel version" is particularly advantageous for larger systems. It displays where the system failure or emergency occurred on a screen.

The height and material used for the belt incline are dependent on material and throughput. A smooth inner surface promotes a near frictionless flow of material.

The hole patterns on the conveyor's sides mean sprinkler pipes or cable trays (cable racks) can be attached – an efficient, space-saving solution.

Depending on the height of the belt, railings can be installed on one or both sides. When standing on the catwalk, there is usually no railing on the conveyor belt side if it is at waist height.

Integrated "impact tables" are made from a combination of plastic and rubber that "catch" the material. An impact table is recommended for particularly heavy material.

In the feeder area, buffer rolls can be positioned in a tighter formation than usual. This configuration protects the conveyor and belt from heavy materials.

Production systems are often spread over several factory floors. A conveyor belt then transports the material from one factory floor to the other. In these circumstances, fireproof partitions can be installed as a safety precaution. These are closed by a signal from the fire alarm system so that no burning material can pass from one part of the building to the other.

Using a radial slewing conveyor ensures that material discharged from the conveyor belt into heaps is more evenly distributed and does not grow higher than the conveyor belt itself. A sensor detects the height of the material pile and swivels the conveyor belt to the left or right – up to 180°.

GÜNTHER use maintenance-free bearings (4-hole flange bearings). Their specially designed sealing system protects the rolling bearing from the ingress of coarse and fine dirt particles.
