Feed Mixers Types

2016-03-23
Feed mixers are used in feed mills for the mixing of feed ingredients and premixes. The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. If feed is not mixed properly, ingredients and nutrients will not be properly distributed with it comes time to extrude, pelletize the feed, or if the feed is to be used as mash. This means that the feed will not have even nutritional benefit would be bad for the animal/fish/shrimp that are feeding on the Forage. Mixers used on the farm are usually vertical, horizontal, proportioner mills,or grinder-mixer combination. Of these, the last is the most common.
The vertical mixer consists of one or more vertical screws which elevate the ingredients to the top of the mixer where they fall by gravity to the bottom, to be mixed and re-elevated. Vertical mixers are the most common type found in small livestock feed mills. However, the vertical type is less well suited to aquaculture, poultry and fish feeds than the horizontal type, which are much more efficient in blending in small quantities of liquids (such as added lipids) or in mixing ingredients with different particle sizes.
Horizontal mixers consist of a series of paddles or metal ribbon blades mounted on a horizontal rotor within a semi-circular trough. The blades move the material from one end of the mixer to the other, tumbling it as it goes. These mixers usually discharge the mixed product from the bottom, using the same mixer blade action. See above for inside views of both a paddle mixer and a ribbon mixer.
 
 
For proportioner mixers, volumetric measures are used to meter the required proportions of each ingredient. An advantage of this system is continuous operation over extended periods.
Grinder-mixers are basically single screw vertical mixers with additional equipment added. Presence of the added equipment increases the quantity of residual feed left in the machine (may be 150 pounds or more) after the last feed comes out of the discharge auger. Obviously the potential for significant carryover of medicated feed in grinder-mixers is high. A switch to a nonmedicated feed requires anintense cleaning of this type of machine. Physical cleaning (i.e.vacuuming, sweeping, or washing) is the most effective means of avoiding contamination of subsequent batches.
 
Fianlly,Allance Machinery can procides various feed mixing machines with high quality and resonable price. It's also worth mentioning that SSHJ Series Double-shaft Mixer equipped with return air pipe, without dust leakage is widely used for mixing of powdery, granular, flaky and blocky materials in the industry of feed, food, chemical industry and fertilizer,etc.
