The main structure: dry granulator comprises a frame, transmission system, the fuselage, hopper, swing cylinder etc.. Dry granulation technology is a new granulation technology in recent years, widely used in rotary dry press roller or flat compression granulation machine. Dry granulating machine technology by roller press granulating machine. In the use of high pressure granulating method for the granulation process, the powder is by applying external force and pressed into dense state in limited space. Produce a stable gathering force floc bridging force, low viscosity liquid adhesive force, surface tension and mutual attraction. Reunion operation success or not, depends on the one hand on the effective use of applied force and transfer, physical properties, on the other hand also depends on the particle material.
Particle shape refers to a grain boundary or each point on the surface of the image. Particle shape directly affect other properties of powders, such as liquidity, filling and so on, but also directly behavior and particles in mixing, storage, transport, sintering and other units in the process of the relevant. Engineering, according to a different purpose, people shape on the particles have different requirements. For example: high speed dry pressing method tile green powder, requirements during mold filling fast, smooth exhaust, the spherical particle is appropriate; concrete aggregate is filled with high structural strength and tight, so the stone shape hope is a regular polyhedron. In turn, particle shape because of different formation process and different, for example, sheet products simple swing type jaw crusher the opportunity to produce more; powder prepared by spray drying is more spherical particles. Therefore, to describe the various particle shapes need quantitative, to show the difference between.
Dry granulating machine has the advantages of adding materials in traditional Chinese medicine extract powder, can be directly granulation, without wet, mixing, drying and other processes, process is simple, can effectively ensure the quality of traditional Chinese medicine. Dry granulator is applicable to a variety of materials, so the dry granulating machine pressure, feeding, crushing, pressing, whole grain speed can be adjusted, so that the operation of dry granulator requirements will be higher, general factory manufacturers will provide a relative parameters, but in practical use to make reasonable adjustment according to the the material properties and the required particle solid degree, particle size, generally for the material better fluidity, the feeding speed can be slower, easy to form the material pressure may be smaller, the situation for larger particles, crushing granulation speed can slow down a bit, as long as not blocking the screen mesh can be, in adjustment, the other parameters unchanged, changing a parameter adjustment.
In adjusting the parameters, as long as the master of the meaning of each parameter can be adjusted in the actual operation, according to the specific circumstances, also depend on trial experience, to achieve the best results.
Dry granulating machine technology, innovation is a strategy of granulation technology, this model realizes the dealer and the approval of granular material pig farms into grain processing plant, save many intermediate links, reduce a lot of intermediate cost. For example: transportation costs, marketing costs, processing costs, enhance the competitiveness of terminal itself. |
