Key Features Required in Feed Machines


A. Intake Section

  • Aspiration system at dumping points for dust free operation.
  • Minimum opening of dumping point grills (to avoid corn cobs, stones and other impurities.
  • Overload sensor at intake chain conveyor
  • Dumping points at each 30 feet.( depends upon layout )
  • Jute remover before intake elevator at ground floor.
  • Speed and overload sensors at intake elevator.
  • Self-cleaning magnet system
  • Crowned shape drum pulley for better belt life and self-centricity.
B. Batching Section
  • Capacity of bins as per formulation and requirement of ingredients i.e. bigger capacity bins for maize, soya and smaller bins for fibrous and ingredients having less flow ability.
  • Provision for bin discharge.
  • No dead corners
  • Gravity feeder for free flowing materials and screw feeder for fibrous ingredients.
  • Variable pitch screw feeder for more uniform flow.
  • Batching accuracy with +/- 0.25% tolerance.
  • Day report – MIS, raw material consumption, batching, process loss, finish good record.
C. Grinding Section
  • Hammer should be capable to provide 600-900 microns with minimum power consumption.
  • Optimum tip speed ( 17500 – 22000 feet/min)
  • Minimum heat generation during grinding. ( less than 5 degree)
  • Quick Gap Adjustment between hammer tip and screen for different type of feeds.
  • Brake provision to minimize the hammer & screen changing time.
  • Aspiration system for better efficiency and heat dissipation.
  • Pocketed design rotary feeder for more uniform feeding.( with magnet plate)
  • VFD on hammer mill Main Motor –for different types of feed.
  • Side support rings – for equal wear of side and other beaters.
  • Dynamical Balanced rotor within 5 Grams.
  • Each beater of same weight
  • Minimum 45 % opening area of Screen.
  • Automatic greasing provision.
  • Vibration and temp monitoring system – hammer mill.
  • Hammer mill at ground floor.
  • Auto indication to check wearing of beaters.
D. Mixing Section
  • CV< 5 within 5-6 Minutes mixing time.
  • Interlocking medicine dosing system for overdose and under dose.
  • Minimum heat generation during mixing.
E. Conditioning & Pelleting
  • Double shaft conditioners – better absorption of steam.
  • Separate motor for each shaft.
  • Minimum 60 seconds of retention – adjustment up to 90 seconds.
  • All steam contacting parts – SS 304
  • Magnet at pellet mill Chute.
  • Quick die changing arrangement.
  • Wider counter pulley for better surface contact of belts and better efficiency.
  • Split housing of pellet mill for easy maintenance
  • Automatic greasing mechanism
  • Spherical roller bearings.
F. Cooling Section
  • Octagon design for more uniform cooling.
  • Rotary spreader for uniform bed level.
  • Auto bed arrangement locks mechanism in case of power failure to prevent the bed leakage.
  • Arrangement for temperature and moisture variation.
G. Crumbling & Screening
  • Design that provides minimum dust.
  • Crumbler BY-Pass Provision.
  • Better Provision to check crumbling samples.
  • Auto- indication to check wearing of crumbler rolls.
  • Two small screens instead of one big screen for better efficiency.
  • Self-cleaning mechanism
  • Better screen tightening sytem.
