In the quarry industry, powerful machinery like crushers require the reliable transmission of power and torque from the motor to the crusher itself. This is where belts come into play, serving a crucial role in ensuring the efficient operation of this equipment. According to Rob Michelson, National Product Manager for Belts at Motion, with over 35 years of experience in power transmission products, including belts, chains, gearboxes, and couplings, “The key with crushing applications is to improve reliability. Downtime is a huge cost to our customers.”

“There is a lot of heavy vibrations and high impact loads on crushing operations that can really do a number on belted equipment. On a standard crusher, there can be up to a dozen or more belts transmitting power and torque from the motor to the crusher,” says Rob.

These demanding operating conditions pose a significant risk to traditional belts, often resulting in frequent failures that can lead to costly periods of inactivity and reduced production. However, by utilising Gates® Predator™ V-belts, operators can enjoy a notable advantage – the prevention of downtime. This is a crucial benefit as it helps to avoid substantial financial losses associated with halted operations and decreased productivity.

“Belt failures often occur due to six common problems: improper tension, misalignment, improper handling, hardware issues, environmental factors, and drive design,” explains Rob.

He further emphasises, “Predator™ belts effectively address these issues, providing a reliable and durable solution that minimises the risk of failure.”

“Predator™ belts have proved themselves in the toughest, dirtiest, and most aggressive applications. They reduce drive cost up to 35%, drive width up to 50%, and drive weight up to 50%,” says Rob.

These belts can handle 1.4-2.2 times more power than equivalent size standard V-belts, allowing for the design of more compact drives that weigh less, put less strain on components, and use fewer belts, ultimately saving money, highlights Rob.

Rob expands on the capabilities of Predator™ belts, stating that these belts are capable of handling various challenges commonly encountered in the quarry industry.

“Whether it’s high-power motors, shock loads resulting from sudden starts and stops, operating in dirty environments, dealing with high heat, or facing contamination from oil and solvents, Predator™ V-belts can handle them all,” says Rob.

Rob goes on to highlight specific features of Predator™ belts, explaining, “These belts are designed with a double-layer fabric cover that is resistant to abrasion and punctures. This feature helps reduce friction and heat build-up during shock loads.”

He further explains that the utilisation of aramid fibre tensile cords in Predator™ belts effectively decreases belt stretch by 50% when compared to standard V-belts. This significant reduction in stretch reduces the frequency at which retensioning is required.

Additionally, the belts are constructed with a neoprene body that exhibits exceptional resistance to oil and heat, surpassing the performance of other rubber materials commonly used in harsh operating conditions.

Moreover, the patented curved sidewall design of Predator™ belts plays a crucial role in extending the belt’s lifespan and minimising wear on both the belt and pulley. To further enhance their performance, Predator™ belts feature a multiple-layer tie band that enables their interconnection into a Predator™ PowerBand™. This design characteristic enhances lateral rigidity, effectively minimising vibration and preventing belt turnover when used on multi-groove pulleys.

“Working with Gates® grants access to their extensive expertise and legacy. They have remained at the forefront of belt technology, continuously advancing V-belt designs,” explains Rob. He further adds, “Their reliable belting solutions ensure that we stay ahead of the competition, providing us with a significant advantage.”
