Martin Engineering introduced a new family of electric screen vibrators for regular duty and hazardous environments. Designed to deliver up to 16,500 pounds of centrifugal force for efficient material separation, Martin screen vibrators are built to withstand the rigors of industrial applications and continuous use, and can run 24/7, as needed.
With a traditional screen vibrator, the drive functions as the energy source. The energy is transferred via a structural bridge to the vibratory box, which is isolated by the springs. In the new Martin 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 kinds of vibratory screens. The new vibrators can be used with a variable-frequency drive in ordinary and hazardous atmospheres. Explosion-proof models are ETL/cETL/ATEX/IECex–certified for hazardous duty.
