GLZ-25 dry granulating machine is a dry granulating machine developed by our company for testing. It is a small zui dry granulating machine for laboratory research and development. It is suitable for laboratories, intermediate experimental devices and small-scale production. It only needs about 80 grams of dry powder to form. According to the principle of mechanical extrusion granulation process, the configured dry powder or micro crystal raw materials with certain crystal water are extruded into thin sheets, and then through the granulation system, particles of the required size are made through the screen. Raw materials can be fed into the hopper through manual or vacuum feeding machine, conveyed and compressed by vertically placed feeding screw, and pushed to the bite angle of two extrusion rollers; Extrude the raw materials into thin sheets through the horizontally placed pressing rollers (the speed of the pressing rollers determines the time for the materials to stay in the rolling area); The pressure required by the material is transmitted to the press roll linearly through the hydraulic device. The press roll arranged vertically can ensure the reliability of the material density. The machine is easy to assemble, disassemble and clean.
According to different particle size requirements, the screen mesh size in the equipment granulation system can be changed with each other. The powder raw materials are directly made into granular products that meet the user's requirements without any intermediates and additives. After granulation, the product granularity is uniform, the bulk density is significantly increased, and the fluidity is improved, which not only controls the dust flying, but also reduces the waste of powder, which is convenient for storage and transportation, and can control the solubility, porosity, specific surface area, etc. It can be directly used for tablet pressing or capsule filling.
It is especially suitable for granulation of drugs that cannot be pelletized by traditional wet granulation and are unstable under humid and hot conditions. The dry granulation process can replace the assembly line investment of wet granulation, save manpower, material resources and financial resources, and is a new type of equipment for energy conservation and environmental protection.
