Wood
Overview
From the forest to a finished product, there are many different stages during the wood processing. Sawing, debarking, pelletising, veneering, MDF forming & pressing, sanding, stacking, painting… The applications are numerous, but Megadyne has the right range of belts suitable to work in this demanding environment.
Designed to improve power transmission capacity and replace traditionally heavy gears and noisy chains, our PLATINUM timing belt is the latest development in our synchronous system offerings. For high-vibration, heavy-wear applications (often outdoors), we recommend our V-Belt and Pluriband.
Throughout the log cutting, debarking, chipping, and veneer trimming processes, power transmission belts drive saws and blades to prepare the harvested wood for downline manufacturing of plywood and MDF (Medium Density Fiberboard) products.
Megadyne conveyor belts are used to convey woodchips through production operations to make MDF boards. The chips are deposited on the belt, where they’re mixed with adhesives and other chemicals to be pressed and formed into long, wide sheets of MDF — which are frequently used in roofing and flooring applications, as well as in veneered furniture.

Sawmill
Sawmills are generally stationary outdoor operations where logs are cut into lumber. Logs are inserted into one end and undergo a sawing process where boards exit on the other end. Portable sawmills are also used for processing lumber in remote locations or for producing limited volume or speciality milling.
Whether stationary or portable, sawmills commonly use a wide variety of rubber power transmission belts to power the large saw blades used to cut the wood.
The Application Engineering Team at Megadyne collaborated with a manufacturer of portable sawmills to design a drive capable of increasing production capacity in terms of cutting quality and speed. The belt drive would be required to deliver high-precision positioning at high linear speed. As the units are normally located outdoors it would require the drive to work at very low winter as well as high summer temperatures.

Pelletizers
Pelletizers are machines that form material into the shape of a pellet for various uses. The material is compressed through a die to form the pellets. A wide range of different materials are pelletized including chemicals, iron ore, animal feed and wood pellets used for burning in heating stoves.
Pelletizers commonly utilize a two-stage belt drive transmission to achieve the proper gear reduction for desired die speeds. The first stage is normally a shock-absorbing V-belt while the second stage is driven by a synchronous belt. Belts offer a reliable, cost-effective and efficient system with a compact design.
A Pelletizer manufacturer contacted Megadyne regarding issues with their two-stage drive. While some slippage was desirable to absorb frequent peak shock loads on the first stage of the drive, the standard raw edge rubber V-belts used did not last very long on this demanding drive. The slippage caused by the frequent peak loads generated excessive heat, reducing the belt life to unacceptable levels.
Megadyne suggested two different types of premium-quality power transmission belts. Standard, high-performance rubber belts delivered a simple and highly cost-effective solution that exceeded the manufacturers’ requirements. Discover how you can do the same for your drive!
