pelleter

During pelleting the temperature of the meal rises by approximately 10°C, hence the final temperature of pellets from a conditioner pelleter is similar to that of pellets from a cold pelleter.

Generally, the quality of pellets (that is, resistance to break-down after pelleting and during handling) of a given mixture from a conditioner pelleter is marginally better than that from a cold pelleter, but the conditioner pelleter requires a boiler and associated water treatment plant to treat the feed water for the boiler.

In terms of energy requirements for a given output, the energy required for manufacturing half a tonne per hour of pellets in a cold pelleter is approximately equivalent to the sum of energy required to manufacture the same quantity of pellets in a conditioner pelleter plus the energy required to produce the steam for the conditioner.

In a ring die pelleter, the rollers or the die may be driven but in a plate die pelleter the rollers only are driven.

Practical experience shows that for a given pelleter motor size, the output of the pellets will be approximately doubled if meal is pre-conditioned prior to pelleting, or, conversely a cold pelleter of say 25 horse-power will produce only half the output of a conditioner pelleter of 25 horse-power if the energy required to raise the steam is not taken into account.

The die and rollers of a ring die pelleter may operate in a horizontal or vertical plane according to machine design.

Contamination by string, large pieces of metal, wood or stones which could cause extensive damage to machinery can normally be removed on a coarse metal grid fitted over the sack tipping-in point of the feed mill, and permanent magnets will normally remove any tramp ferrous metal which may enter the system, particularly before entering the grinder, mixer or pelleter.

After mixing for a pre-determined time, normally 10-15 minutes (although this time may be shorter in some mixes), the mixture is discharged into a bag or conveyed by auger or bucket elevator to a storage bin or pelleter.

But the extra poke should prove useful when towing or carrying a slug-pelleter.
