Heavy-duty vibrators for continuous duty

Bulk material handlers in a wide array of industries, including coal, are improving process flow and efficiency with the Cougar® B Series of heavy-duty vibrators from Martin Engineering. Rated for continuous duty – even at maximum force settings – the vibrators deliver enhanced reliability and extended service life by minimising accumulation in storage vessels, transfer chutes, dust collectors and other locations, maintaining throughput and reducing maintenance time required to clear blockages. All models are totally-enclosed, non-vented (TENV) designs with Class H high-temperature windings and IP-66 rated enclosures.

“Some manufacturers use Class F windings,” explained Martin Engineering product specialist David Ruggio. “That typically allows continuous duty at mid-level force ratings, but we wanted to design these units to go beyond that kind of performance. The benefit is a cooler-running vibrator that lasts longer in demanding service conditions.”

With dozens of different models available, Martin Engineering offers the water-tight, dust-tight designs in a wide selection of voltages, speeds, force ratings and frequencies to suit virtually any application – including hazardous locations. Specific models range from 70 lb of centrifugal force output to 16,500 lb, in speed ranges of 850, 1170, 1750 and 3450 rpm. All of the B Series vibrators are electric and assembled in the US.

“We’re seeing many plants taking steps to reduce their consumption of compressed air,” Ruggio continued. “These electric designs are replacing pneumatic vibrators in many applications, which helps cut down plant air use. In most situations, a 1 hp. electric vibrator will perform the same amount of work as a pneumatic design requiring a 10 – 15 hp. compressor. Electric units are also extremely low-maintenance when compared to pneumatics, and they’re much quieter,” he said.
