Latest screen vibrators from Martin Engineering
Electric screen vibrators provide efficient material separation in hazardous environments
MARTIN Engineering have introduced a new range of electric screen vibrators for regular-duty and hazardous environments. Designed to deliver up to 16,500 lbs of centrifugal force for efficient material separation, the screen vibrators are built specifically to withstand the rigors of industrial applications and continuous use.
‘With a traditional screen vibrator, the drive functions as the energy source,’ explained Robert Nogaj, vice-president of operations and product management at Martin Engineering. ‘The energy is transferred via a structural bridge to the vibratory box, which is isolated by the springs. With our new design, the energy source is an integral part of the structural tube that can be mounted to the sides or top of a vibratory box, making it much easier for designers to engineer and manufacture new types of vibratory screens.’
The new line of vibrators will be manufactured in Martin Engineering facilities worldwide to meet short lead times and quick service response. The robustly designed screen vibrators provide the power to sort or separate material efficiently, as proven in demanding laboratory trials and field applications. The units are manufactured to the highest standards for use in industries where bulk materials, solids and powders are stored or processed.
‘The latest Martin screen vibrator is our very own design. We started with several models, some of which were direct retrofits for the Derrick shaker,’ explained Mr Nogaj. ‘But our drives are fully adjustable, giving the customer more flexibility and creativity in how the vibrators are used. We’re now in the process of expanding the product line beyond the models engineered to retrofit OEM equipment, with a line of much larger drives.’
The Martin Engineering vibrators can be used with variable-frequency drive (VFD) in ordinary and hazardous atmospheres, while explosion-proof models are ETL/cETL/ATEX/IECex certified for hazardous applications.
The versatile dual-voltage product line can be used worldwide and the eccentric weights can be adjusted with hand tools to match ‘High G’ or standard performance screens. No adaptors are requited to fit Derrick vibrating screens, as these direct-replacement units can be bolted and wired to existing connections. The only service required on the screen vibrators is lubrication every 2,000h, while the long-life bearings produce less noise than OEM oil bath bearings.
