The original NEMA Premium labeling scheme was designed to simplify the identification and application of NEMA Premium efficient motors by end users and original equipment manufacturers (OEMs). Since its inception, the NEMA Premium mark has gained wide acceptance with motor buyers, utilities, and other specifying organizations. The recognition of NEMA Premium has expanded from the United States to many countries around the globe. NEMA standards include efficiency levels for 60Hz as well as 50 Hz operation.

The National Electrical Manufacturers Association has made significant changes to motor efficiency compliance verification requirements for NEMA Premium licensees.

Motor manufacturers that license NEMA Premium agree that the license is granted on the express condition that the licensee will comply with the NEMA Premium Efficiency Electric Motor Program guidelines which include how to use the NEMA Premium mark along with guidelines of the efficiency verification program. The licensee must agree to follow the guidelines or be subject to termination of the license and the loss of use of the NEMA Premium mark.

NEMA Premium Efficiency Specifications are the energy efficiency levels at which electric motors can qualify for the NEMA Premium designation and are consistent with NEMA MG1 table 12-12. These levels are subject to future review and NEMA expressly reserves the right to maintain or change these levels at any time, consistent with NEMA’s Standardization Policies and Procedures, to maintain the viability and credibility of the NEMA Premium Efficiency Electric Motor Program and its goals. If the efficiency levels are changed at any time by NEMA, the licensee will have 180 days to revise his product to conform to the revised specifications of the NEMA Premium Efficiency Electric Motor Program.

Combustible dusts, according to OSHA, are any combustible solid material composed to distinct particles or pieces, regardless of shape, size or chemical composition that presents a fire or deflagration (exposion) hazard when suspended in air. The National Fire Protection Assoc (NFPA) states that any material that will burn in air as a solid can be explosive in a finely-divided form, and any industrial process that reduces materials into small particles presents a potential for a serious fire or explosion. Facilities that manufacture powders, as well as, those that incidentally generate them through the handling and processing of solid materials are subject to the combustible dust hazard. These materials such as, various metals, wood, plastic, rubber, coal, flour, sugar, and paper. Below are several links that discuss the potential hazards, and prevention of dust explosions.

Sustainable Plant magazine’s June 2012 edition features an in-depth article about the danger of combustible dust.

Aside from all the proper adjustments and operating parameters required to gain the most in screening efficiency, the need for good preventive maintenance practices is a must for longer lasting screens and reliable performance. “Above all, be proactive,” says Deister Machine Co. Service Manager Scott Murphy, an industry veteran with more than 25 years of experience. “Develop a keen focus in forecasting, and then fixing, each factor that could cause potential problems. And take the time to do maintenance the right way — before, rather than after, component failures occur.” Murphy shares the following tips for superior screen maintenance.

Establish an oil sampling program.
Employ recommended lubrication practices.
Maintain proper belt tension.
Prevent material buildup.
Maintain proper screen media support and tensioning.
