Tips for Choosing Pellet Mill

With people's increased awareness of protecting the environment, more and more people pay much attention to the biomass energy.  It is becoming a trend that biomass pellet replace the traditional coal energy.

Along with this trend, many kinds of pellet mill emerge as the times require. How to choose a suitable pellet mill, there is some tips for your reference.

In general, there are two kinds of pellet mill, flat die pellet mill and ring die pellet mill. The ring die pellet mill includes horizontal type and vertical type.

The first type is flat die pellet mill: on the base of machinery circular motion, motor or diesel engine as power to drive the drive shaft. It passes gear to main shaft and flat die, and rubs rollers to move. Under the pressure of rollers, the materials are extruded in the die holes, and finished pellets come out of outlet through knives' fragment. Flat die pellet mill is widely used in biological fertilizer, organic fertilizer, compound fertilizer low temperature pelleting.

The second type is horizontal ring die pellet mill: Horizontal ring-die pellet mill's die is rotary then rub the roller move, its pressure is smaller than flat die, but it is suitable for those materials which easy to press such as animal feed. They are widely used in feed factories, breed aquatics factories, organic fertilizer factories, chemical factories, and China traditional medicine factories etc. It can be used together with powder material.

The third type is vertical ring die pellet mill . The heart part adopts "double-layer die" as the unique structure; the roller are made by abrasion-proof alloy steel, improving the using life of spare parts greatly; For the drive parts, the grease is filtrated automatically lubricated properly.
 
1. Vertical die, feeding vertically; No arching of raw materials, easy for heating dissipation.
2. Die fixed, rollers rotating, materials centrifugal, evenly distributed around.
3. Double-layer dies, up and down dual-use, high capacity, saving energy.
4. Independent lubrication: high pressure filtration, clean and unblocked.
5. Independent and frequency changeable cutting device, ensure formation rate of pellets.

The equipment is applied to the materials with low adhesiveness and low shaping, such as the rice husk, sunflower seed husk, peanut shell and other fruit shell; branch, trunk, bark and other wood waste; a variety of crop straws, rubber, cement, ash and other chemical materials. This type of pellet mill is widely used in the biomass-energy fuels plant, power plant, wood processing plant, fertilizer plant, chemical plant etc. It is the ideal pressing shaping equipments with low investment and high profit.
   
In conclusion, Flat die is suitable for pressing biological fertilizer, organic fertilizer, and compound fertilizer. Horizontal ring die is suitable for pressing animal feed pellet and its capacity is big and the pellet quality is good for feed animals. Vertical ring die is suitable for pressing biomass pellet.
