Description
Technical field：
The invention belongs to agricultural machinery technological fields, more particularly to mechanical pelleting technical field.
Technical background：
In agricultural production, compound fertilizer is applied in farmland extensively, promotes crop growth.Compound fertilizer is using
Before, it needs to mix various powders shape chemical fertilizer, with granulating technique, mixed powder is prepared into the particle of certain size, with
This state is applied in farmland.As level of farming mechanization is continuously improved, many areas are applied using mechanized equipment
Fertilizer requires also to be continuously improved to compound fertilizer granules size.Leading indicator is：Particle will have some strength and density, particle size
Control errors are within 5% etc. between controlling stringent, varying particle size, therefore propose increasingly higher demands to granulating technique.
Two pairs of rollers extruding granulation equipment is widely used in chemical fertilizer production.The equipment is divided into hot Granulation Equipments and cold Granulation Equipments
Two types.Hot Granulation Equipments is the extrusion forming into mold after powder is heated.And cold Granulation Equipments is without adding powder
The powder mixed is directly input to extrusion forming in mold by heat.Due to hot Granulation Equipments need by the use of large-sized boiler as heat
Source, and steam coal will generation environment pollution.Boiler, which is built, at present needs stringent examination ＆ approval, the heavy construction being badly in need of except country
Outside, general area does not allow to build boiler.So hot granulating technique development is restricted.And two pairs of rollers squeeze cold granulating technique, into
Mainstream technology for composite heat transfer.This method is divided into the realization of two steps：
The first step：Between chemical fertilizer powder is input to two rolls reversely rotated at the same speed with scroll feeder, to edging
It is pressed into certain size and intensity, the sheet-like particle connector for thering are several particles to link together.
Second step：It is with the grain separating machine below roll that these sheet-like particle connectors are broken apart for the single of dispersion
Particle.
The commercial particulate seperator of second step is completed at present generally using " mace " structure, and sheet-like particle connector enters
Between two " maces " reversely rotated at the same speed, it is desirable to the latter by coupling part between particle i.e. material thinnest part
It interrupts, sheet-like particle connector is separated into individual particle.
However this grain separating machine for being commonly called as " mace " structure is ineffective, has the following problems：By sheet-like particle
Connector is broken apart into individual particle, needs certain power.Due to each sheet-like particle connector, the numbers of particles of connection is not
Together, so needing the size of broken power also different.The particle of sheet-like particle connector connection is more, and the crushing force needed is larger
When, if crushing force is less than normal, sheet-like particle connector cannot detach；And the particle of sheet-like particle connector connection is less, needs
Crushing force it is smaller when, if crushing force is bigger than normal to break the particles down into powder.And this grain separating machine, crushing force is can not
With adjusting.In order to ensure to crush, it has to its crushing force are designed higher, therefore caused in sheet-like particle connector very
More particles have been broken into powder again when being detached.So the ratio of briquetting of separation particle is not high.Practice have shown that；It is used in cold granulation
The broken apart method of " mace " structure, grain forming rate generally only has 40-60% or so, and 40-60% or so is still
Powder must be granulated again.Environment is seriously polluted in the presence of a large amount of powder, and pole is unfavorable for the health of operating personnel.Particle discretely-formed
Rate is low, wastes mass energy and manual labor.In short, the presently commercially available common grain separating machine for being commonly called as " mace " structure,
The concrete condition adjustment crushing force of sheet-like particle connector cannot be directed to, causes ratio of briquetting is low to be attached to pollution.
