Description
Technical field
The present invention relates to grain machinery fields more particularly to a kind of grain, and granulator is mixed.
Background technique
As China's grain machinery industry manufacturing technology constantly improves, the process unit and processing technology of grain granulator
Also it is rapidly developed.Grain granulator is grain machinery and important one of the machining equipment of animal husbandry, can will
Processed grain fine particle or powder and water or nutrient solution are crushed to spherical or short cylindrical shape particle after being mixed, and use
Soil is nourished in feeding animals or being used as fertilizer.
At present according to the difference of profiled part in granulating system, granulator can be divided into indent rolling granulators, gear is nibbled
Box-like granulator, spiral granulator, roller type (roller can also be claimed) granulator.Wherein the application of roller type granulator is the widest
It is general, roller type granulator is usually divided into flat-die type powdered granulator and two kinds of ring die type pellet mill.Relative to flat-die type powdered granulator, ring
The production technology level and technical performance of mode granulator are greatly improved, and energy consumption is also fewer than flat-die type powdered granulator, because
This ring die type pellet mill occupation rate of market is higher.Ring die type pellet mill is typically referred to corn, dregs of beans, stalk, grass, rice husk etc.
The feed processing machinery of crushed material direct pressing particle.According to function different demarcation, ring moulds granulator overall structure is broadly divided into
Feeding part and crimping section, feeding part mainly use machinery forced formula to feed, and enter the distribution of material high-speed rotating centrifugal
Material is truncated by scraper in granulating chamber.Crimping section is mainly completed in steel die, and two pressure rollers are arranged in ring moulds,
When work, wedge shaped squeeze room, by the relative rotation of ring moulds and pressure roller, the indoor material of wedge shaped squeeze are formed in ring moulds and pressure roller
Interior ring moulds are squeezed out by powerful active force, complete granulation.However, in practical applications, there are many technologies to lack for ring moulds granulator
Falling into influences its processing efficiency, processing quality and flexibility (adaptability) of operation.For example, being easy to appear when using two pressure rollers or Multi-roller extruding mixing
There is the non-uniform situation of stuck or binder in imbalance state.For another example, the hole of steel rings mould surface processing must be processed according to particle
The technical requirements of diameter carry out drilling processing, when mixing particle diameter changes, it is necessary to the steel ring moulds processed and more renewed, no
Only disassembly and assembly difficulty, and delay working hour and reduce processing efficiency.In addition, conventional ring moulds granulator is sent by hopper
Mixed material is easy knot arch putty, keeps it unevenly distributed in die cavity when handling the hard ware materials such as cotton bavin particle, stalk, sawdust
And pressure roller unbalance stress is caused, main shaft bending deformation is caused, fuselage judder is caused, destroys bearing.Therefore, in ring die pelletizing
On the basis of machine working principle, a kind of power foot is invented, small in size, stability is good, interchangeability is strong, high-efficient, adaptable
Granulator is a variety of industries such as current grain machinery, animal husbandry, chemical industry technical problem urgently to be resolved.
