Vibramech’s exclusively appointed R&D mechanical engineers focus their competencies on a wide range of structural improvements and innovative design changes, across all of its products. They conduct continuous research programmes on a variety of dynamics, from ‘simple’ rubber buffers to ‘complex’ beam designs.

“Our team utilises the most advanced simulation software to conduct finite element analysis (FEA), as well as multibody dynamic analysis to improve engineering efficiency and to optimise components in their design phase. This is followed by various experimental tests such as destructive and non-destructive tests, modal and vibration tests to ensure that integrity and reliability of our products are maintained,” Massey outlines.

More recently, the company has started employing new technologies such as wireless sensors to periodically measure the performance of its client’s equipment. This enables Vibramech to source good quality data about the health and condition of its equipment in the field, and to respond to any potential breakdown before a client is aware of the threat.

“We understand the harsh operating conditions which vibrating screens, grizzlies and feeders are subjected to in the mining industry, world-wide. As such, we are cognisant that our designs need to cater for both abrasive and corrosive environments. As sound dynamic behaviour is essential to ensure vibrating equipment reliability, all equipment is built to perform within strict dynamic parameters. All internal mating surfaces are machined in order to maintain stringent dimensional tolerances,” Massey states.

In addition, the company’s quality assurance programme makes provision for a full 3D vibration analysis to be conducted on all equipment prior to release. This is used as a benchmark for the life of the equipment.

As an original equipment manufacturer (OEM), all equipment is manufactured in-house by Vibramech at its 20 000 m2 premises in Chamdor, 35 km west of Johannesburg, South Africa. Almost every piece of equipment is tailor-made to suit a client’s specific requirements, from both a plant layout viewpoint and process considerations.

A present staff complement of 200 control all activities from sales through to engineering and manufacturing. All equipment is designed and manufactured by Vibramech without the use of manufacturing subcontractors. This ensures complete control over quality and scheduling. Furthermore, its flexible and practical approach to screen design enables the client to optimise the vibrating equipment geometry to suit its specific requirements, resulting in tailor-made equipment.

Vibrator motor and geared exciter repairs form part of Vibramech’s service offering, with repairs conducted to OEM specifications. URAS vibrator motors and geared exciters are part of Vibramech’s key product offering, which, along with other OEM vibrator motors and geared exciters, are repaired at Vibramech’s factory.

Vibramech has distributed URAS vibrator motors as part of its vibrating equipment product offering since 1981 and is the exclusive URAS vibrator motor distributor for Africa and the Middle East.

Vibramech ensures a robust equipment design that will provide many years of reliable service, resulting in lower operating cost and reduced down time.
