The facility to correct belt alignment is a key factor for preventing product spillage on belt conveyor installations. Flexco Europe GmbH supplies a range of belt centring devices for this very purpose. These systems use sensors to identify and correct any off-tracking. This also helps reduce and even eliminate damage to the belt edges, which means that fitting a centring system not only significantly reduces product spillage but also cuts maintenance costs.
Does the belt wander to just one side or does it move to and fro between both sides of the installation? Is off-tracking a constant problem or does it only happen occasionally? Has the belt developed an undulating wear pattern and is it under low, medium or high tension? These are the kind of questions belt operators have to ask before they can select the most suitable belt centring system. Flexco can help them make the right decision and can offer a range of easy-to-install solutions for all belt sizes and tensions.
For belts that have a tendency to wander to one side only the Flexco ‘belt positioner’ is an adaptable and simple device that is easy to install and maintain. The angled setting of the rollers ensures that the belt always runs straight. This system, which
is only for fitting to the bottom run, is suitable for belts with a maximum tension of
210 N/mm and a width range between
450 and 2400 mm.
Flexco recommends the PT Smart range for belts operating at an average tension of maximum 280 N/mm. Sensor rollers are used to detect belt wander and the system’s unique turn-and-tilt movement guides the belt back into its correct position. PT Smart units can be fitted as standard to belts in the width range 400 to 1800 mm and up to 25 mm in thickness. The Flexco portfolio also includes belt centring systems designed specifically for use below ground. These use materials and components specially adapted for the temperature and operating conditions of the mining industry.
The company also has a PT Max range for extreme belt tensions up to 525 N/mm and for cambered belts. Here too sensor rollers are used to detect belt wander. If necessary, the belt is then guided back to its correct position. The operator can install these systems on either the top strand or the bottom strand, according to the application. The devices can also operate in both dry and humid environments. The standard sizes in this range are suitable for belt widths of 650 to 1400 mm. The bottom-strand design is suitable for belt thicknesses of up to 25 mm and the top-strand system for thicknesses of up to 19 mm.
Operators of heavy-duty belts, where belt tension may be as much as 1,060 N/mm, will require the HD PT Max range. These units operate in the same way as the PT Smart and Max range. They can be fitted to both the top strand and the bottom strand, according to requirements, and are designed for belt widths of 1200 mm and above.
