What is the widest modular belt I can use?
Because of its bricklayed construction there is no limiting width factor on modular belts. Belt widths of 5 m / 200 in. and above are not unusual.In fact, modular belts are a great solution for short center distances and wide belts thanks to the positive drive and tracking system.
What are modular belts?
Lakhotia modular belts are constructed with modules molded from thermoplastic materials connected with solid plastic rods. The all plastic design promotes long life and superior performance in many applications. Sprockets eliminate the need for high-tension systems by positively engaging the belt and maintaining proper belt alignment.
Is modular belting noisy?
Noise depends on the following:
Belt pitch (the smaller, the better)
Belt material (the softer, the better: PE best, PP better than POM)
Sprocket size (the larger, the better)
Thanks to its double row teeth,
What is the polygon effect?
Module and chain links moving around the radius of the sprocket causes the linear belt speed to vary. The pivot rod travels on the pitch diameter of the sprocket while the module moves through the smaller chordal radius causing a horizontal rise and fall of the module.This polygon effect is typical to all Modular Belt systems. The magnitude of speed variation is dependent on the number of sprocket teeth.
How to clean belts?
We recommend that you keep your belts' adhesive qualities intact by cleaning and conditioning belts when necessary. A clean belt will properly offer the friction qualities it should.
Soap and water: For all belt types; Nylon belts should be dried after washing
Alcohol: Spot cleaning on all belts
Alkalis (low concentration): Not for use on EPDM rubber
Ammonia: Not for use on NBR, EPDM or Silicone
Borax: Good for all belting
Chlorine: Do not use
Kerosene: Not for use on PVC or EPDM covers
Live Steam: Not for use on Nylon belts
Household cleaners: Many are useful, check formulation and perform a spot test
Quaternary Ammonia: Useful for cleaning/sanitizing food conveyor belts
Please note: Combinations of agents may cause unpredictable damage.
What is the max. temperature for modular belts?
The max. possible temperature for long-term exposure is 200 °C / 392 °F, for short-term it's even higher: 240 °C / 464 °F. But this depends on the application and of course on the belting material in use. The values mentioned are for ST material only.
What is the right tension when installing a fabric conveyor and processing belt?
The belt has to be tensioned as much as needed to convey the maximal load without slip in all possible operational conditions. For PET-fabric belts, Habasit recommends a minimal initial tension of 0.3%. The optimal tension depends on belt type and operating conditions - should not exceed 1%.The initial tension of processing belts like printing blankets depends on application and machine
What are possible reasons for joint failure?
A general answer cannot be given, as joint failure depends largely on the application circumstances. The joint is in general the weakest part of the belt so any overload is likely to show up there first. Among the factors that can cause joint failure are:
Application of insufficient or excessive initial tension
Higher application temperature than recommended
Mechanical problems (e.g. belt edges touching installation parts)
Smaller pulley diameter than recommended
PVC, TPU or TPO? When should I use a PVC belt and when should I use a Thermoplastic Polyurethane (TPU) or a Polyolefine (TPO) belt?
As a rule of thumb, for low-end applications without special demands PVC-coated belts normally will do the job. On the other hand, more demanding or specific applications can require appropriate product features. As a general recommendation the following can be kept in mind:
suitable for most low-end applications
resistant to most chemicals (except solvents, oil)
superior abrasion resistance
TPU (Thermoplastic Polyurethane)
superior strength for mechanically demanding applications
good abrasion resistance
good temperature resistance for a wide range of applications
TPO (Thermoplastic Polyolefin)
excellent release and antisticking properties
excellent chemical resistance
excellent low temperature properties
Other coating materials Belts with different coating materials, like PU, NBR, EPDM, silicone etc., are available upon request.
Can I use modular belts in a metal detector?
Modular belts are an excellent solution for metal detectors: Easy to disassemble and re-assemble Easy to repair, less downtime, For sensitive metal detectors uncolored (natural) belt and rod material is preferred since it contains no pigments
Which food belt material suits my cleaning agent?
Working closely with cleaning agent suppliers, Habasit has developed a new chemical resistance information tool that lets us help you match cleaning agents with our range plastic modular belt materials. Making it easier than ever to select the right Habasit solution for your food belts. For further information and support please contact Lakhotia.
