This feed line start with two screw conveyors, one is for pellet material, transfer the pellet materials to grinder, after grinding pellet materials will be fine.The other one feed the mash materials to mixer directly. 
All the materials get together according to the formula in mixer. After mixing, all materials transfer to pelleting bin to ready pellet by one screw conveyor.When do pellet, feeder transfer mash feed to conditioner, inner conditioner can add high temperature steam to make the feed materials’ starch granulate, and kill a part of germs to reduce the cost of anti-epidemic. Starch granulate can improve digestibility of animal feeds. Then go down to pellet mill. Mash feed material get into the press area, rollers push the mash into the ring die hole, out be pellet. Pellet feed has many advantages, such as avoid animals being picky, convenient to transportation. 
Just pellet with high temperature and moisture,need cooling down and remove a part of moisture. Use a fan, cyclone and pipes to wind pellet to cooler. This cooling is against wind cooler. Exhaust fan let the wind pass from bottom of cooler, get in to cooler inner side, pass from pellet, take away the high temperature and moisture, till the temperature and moisture close to room temperature ±5℃, suitable for bagging. Then discharge to crumbler, crumbler will make the big pellet be smaller to suitable for chick.If no need be smaller will be down to bucket elevator to hoist up to rotary sifter, sifter will separate the fine from the pellet,  then we get the product, go to finish product bin. At the end is the bagging process.
