XL-Class Banana – Meeting the demands of the industry

The demand for high-capacity machines with a greater screening surface has led to Haver &Tyler developing technology to overcome the limitations of traditional shaft driven vibrating screen technology.The machine that can meet this demand is the XL- Class Banana.

Haver Australia Business Development Manager Steffen Silge says, the XL-Class Banana screens offer precisely engineered solutions for applications demanding large tonnages in combination with high reliability.

Originally developed for classification on iron and copper ores, the Banana Screen can be used for almost every application within the mining industry, which include gold, bauxite, niobium and others, due to its high operational capacity and simple maintenance.

“The multiple inclination XL-Class Banana, was designed and engineered by Haver & Tyler to provide feed capacity and efficiency of classification,” he says. “The XL-Class Banana is usually used in applications with high amounts of undersize and near size particles,” Steffen explains.

“A greater incline in the feeding area triggers an increase in flow speed and, therefore, a high operational capacity by about 25 percent, assuring a decline on layers height,making the fine material separation easier.Successive incline reductions throughout the screen area ensure a decline in flow speed, creating favourable conditions for a high efficiency on the final process of classification.”

The large deck sizes on the machine result in maximised feed rates and an increase in screening capacity. The bridge-mounted, exciter drive system maximises machine reliability with extended maintenanceintervals, while the 50,000 hour bearing life reduces maintenance costs.

The robust mechanical construction of the machine also features rigid HuckBolts® and no welding on the side plates.
“The XL-Class Banana has a unique rigged structure design, that provides the highest structural reliability through reinforcement plates and reinforcement bending,” Silge says.

“It has also been designed to allow for different configurations of classification decks.” Meanwhile, the company’s signature vibration analysis tool is employed to locate any dynamic irregularities in the vibrating screen.

“The Vibration Analysis system employs up to eight accelerometers that provide a total analysis of the screen’s dynamic performance. This information indicates the machine’s speed, stroke and overallperformance,” Silge says.
“Once your XL-Class Banana is installed, the Vibration Analysis can be performed on a regular basis to help you understand the interaction between feed material, screen media and the vibrating screen specific toyour operation,” he adds.

Haver Australia is also including the Finite Element Analysis (FEA), with each new machine purchase to optimise the XL-Class Banana. This is a structural calculation by means of FEA, which allows the simulation of the machine’s dynamic behaviour through an appropriate model, testing tensions and natural frequencies to assure the predicted results in a technically and economically optimised design.

“This analysis is also used to optimise the vibrating screen’s components in order to avoid high stress concentrations and early fatigue failure,” Steffen explains. “The FEA also checks acceleration and displacement.”
Silge encourages those interested in the XL-Class Banana to contact the team at Haver Australia.
