Working Principle
Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two fixed eccentric shafts whose gears are jogged. When installation, the two gears must be jogged according to the sign. Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, the materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, and avoiding the further crushing, so screening purpose can be reached.
Vibratory Motor

• The Grizzly feeder is suitable to feed primary jaw crushers, selecting the large sizes which require primary crushing, the smaller sizes and any fines which must be eventually rejected.
• The Grizzly vibro feeder consists of a very large vibraring body made of thick plate with inside lining of anti-abrasive plate. The Grizzly vibro feeder is driven by two or four vibrating motors. The vibro feeder(which may either be placed on a steel or concrete base) rests on spring

Calculation of Grizzly Bar Section Area Required
The area needed for the Grizzly Bar Section may be calculated from the following empirical formula and tables. The resulting figure provides a guide to the Grizzly Feeder model required.
Grizzly Bar area (m²) = Tonnes per hour of undersize Capacity/m² A x Factor B x Factor C
Electrical Control Equipment

• Grizzly Feeder may be supplied complete with Variable Feed Rate Controllers. They incorporate the very latest frequency inverter technology for applications that require frequent adjustment of the feed rate.
• For other applications twin vibrator phase reversal braking starters which enable the unit to stop within seconds may be suitable. The number of stop/ starts that may be made per hour is limited depending upon conditions
