04.10.13.06. Suspended Electromagnet/ ILMS
The magnet will be of high permeability cast steel as per IS : 4491 with
an integral terminal box of adequate size. Leads will be brought to the
terminal box through a water tight sealed gland. An earthing terminal will
be provided inside the terminal box. The coil of the magnet will be
designed for continuous duty for full supply voltage. The magnet will be
fed from 220V DC obtained through rectifier panels.
The magnet coil will be Fiber glass wound copper wire and class H
insulation will be used.
Control panel will be free standing, floor mounted, front attended, made
of CRCA sheet steel of thickness not less than 2mm with IP54 enclosure
class. In-comer feeder will have load break switch interlocked with the
door.
Panel will have air cooled control transformer, full wave, silicon diode
rectifier bridge having 220V DC output and complete with RC circuit
across each diode, PIV of diode will not be less than 1560V.
Complete safety and protection equipment against surge voltages,
discharge resistance in DC load side will be provided. Electronic
temperature sensing circuits for protection against excessive
temperature in the magnet coil will also be provided.
For In Line Magnetic Separator necessary electrics will be included.
04.10.13.07. Dust Suppression System
Control Panel for DS system will have necessary starter for Pump
motors and 24V DC power supply arrangement for Solenoid valves.
Valves will be energised either by Local Push button station or by under
