As we know, pelleting machines are developed from feed pellet machines. The
main improvement of pellet machines is the change of working pressure becasue of
feedstock from feed to wood. As a result of raw materials to make feed is fine
material such as corn, soybean meal, cottonseed meal and so on, with the high
rate of adhesion. Moreover, the material will be pre-granulated quenched with
steam, which can play in advance of material softening, in order to get better
granulation and increased gloss particles. But for material like straw, wood
chips, such as crude fiber, low adhesion itself, difficult to shape, if used as
fuel particles, the density need big pressure to achieve. As a result of
renewable energy in recent years gradually rise by the market, the pellet
machines are becoming more and more matured.
Flat die series pellet machine is divided into two or more parallel
roller press machine. They are applied to make organic fertilizer granulation in
the past. For making fuel particles, the high pressure needed will bring a lot
of wear and tear on the machine. Based of research on this problem, we
introduced the German manufacturer of advanced pelletizing technology, combined
with experienced engineers and the joint efforts of relevant departments, the
new series of Pellet Machines are developed. It differs the past with the
following features:
1. The Use of Tapered Press Roller. The ends keep the same thread speed with
the inner, external rings. There is no dislocation friction between roller and
mould, which decrease resistance, reduce the kinetic energy loss, extend the
life of the mold and lower down production cost.
2. Three Observation Doors
in pelletizing room, which easy to clean material at any time and maintain the
equipments.
3. The Press Rollers are placed eaqually in the machine. They can
work stablely. The suppression room increased, which provide the product
efficiency.
4. The Use of Screw Stalk Center Pressure Control Device. The
clearance of moulds can be adjusted bigger or smaller to adapt to different
materials, to ensure that the effect of repress
