2. • Air suction area too small 1000cm sq.
• Air filter dirty - quickly
FLAWS IN ORIGINAL CIRCUIT
• Air suction is too closed to barrel heater causing hot inlet air
• Air suction area is under hopper loader so dust particles
causes frequent replacement of Air Filter
TECHNE Extruder DC Motors
BAREEL HEATER
HOPPER
LOADER
3. Motor running continues with high temperature
Burning winding and mechanism failure
Carbon brush and Carbon Spring damaged on regular basis
Loss of Production for approximately 12 hours.
Repairing cost 5000 to 10000SAR
LOSSES OCCUR DUE TO ORIGINAL
CIRCUIT
6. Better cooling mechanism for the machine(using chill water tank)
Air suction Area increase.
The problem of barrel heater and hopper loader is rectify by changing the direction
of Suction Motor.
DESIGN OF NEW CIRCUIT
7. Advantage of new circuit
1) Air suction area increases to 2925cm sq.
2) Air filter long duration cycle
3) Air with more CFM and child ( MOTOR COLD )
4) Increase life of Motor armature
5) Increase life of Carbon brush
6) No more breakdown
7) High productivity
8) Huge Cost Saving
