Introduction
NEC Electromagnetic Hammers are compact, maintenance free, operates better than any other conventional hammering system
Electromagnetic Hammers prevent clogging and adhesion of powdery and granular materials in Spray Dryers, Cyclone, Hoppers, BINS, Powder conveying ducts, etc
Operational Features
Electromagnetic Hammer consist of a stator and rotar, which are made out of high-grade strip lamination to minimize iron losses. There are two salient poles on the stator over which excitation coils are placed. When the hammer is excited by a short duration electric pulse the rotor takes the position of minimum reluctance to magnetic path. The part movement of the rotar shaft is directly transmitted to hammer stroker. The stroker in turn hits the hopper with strong force and returns to the original position. The excitation of hammer coils is controlled by an electronic controller.clients for offering cost-effective products that are precisely designed according to the clients' specifications. Consequently, we have garnered a rich clientele belonging to different industrial sectors.

Selection Guide
Selection of Electromagnetic Hammer depends on various factors such as plate thickness of chamber, design of stiffeners, type of product etc. however, as a general guide line
- Model NEC-EH-S for plate thickness less than 2mm
- Model NEC-EH-50 for 2mm to 3mm
- Model NEC-EH-75B for heavy impact
- Model NEC-EH-75 for plate thickness 6 to 8mm
Number of hammers depends on surface area of chamber.
