GLZ300 Large Dry Granulator

GLZ300 Large Dry Granulator

Working principle of dry granulation:

Dry granulation is the process of using crystalline water in materials to directly degas, pre shrink, and press the material (powder) into thin sheets through hydraulic pressure. After being processed by a crushing system, graded dust removal and recovery processes, it is made into dry particles that meet customer requirements.
According to the principle of mechanical extrusion granulation process, the prepared dry powder or fine crystal raw materials with a certain amount of crystal water are extruded into thin sheets, and then processed through the granulation system and screened into particles of the desired size.
Raw materials can be manually or vacuum fed into the hopper, transported and compressed by vertically placed feeding screws, and pushed to the bite angle of two extrusion rollers; Squeezing raw materials into thin sheets through horizontally placed rollers (the speed of the rollers determines the duration of the material's stay in the roller pressing zone); The pressure required for the material is linearly transmitted to the pressure roller through a hydraulic device, and the vertically arranged pressure rollers can ensure the density of the material. According to different particle size requirements, the mesh size of the sieve in the equipment granulation system can be replaced with each other.

Characteristics of dry granulation products:

The Guolang large-scale dry granulation machine is widely used in the production of large pharmaceutical factories, food factories, and chemical factories. It requires about 5350 grams of dry powder and obtains the required particles. The particle size can be adjusted to meet different requirements, with high yield, high degree of automation, convenient use, and good universality. Water cooling devices can be added at the pressure wheel according to customer needs.

The electrical part of the GLZ300 fully automatic dry granulation machine adopts PLC touch screen control, and the hydraulic system adopts electric oil pump. It also adds screening and dust removal devices, with a high degree of automation. The feeding, pressing, and granulation speeds can be adjusted, the pressure can be adjusted, and the fineness of the finished product can be adjusted. The granulation cage is improved to increase the yield of finished particles. This machine integrates feeding, tablet pressing, granulation, whole granulation, screening, dust removal and other devices. Directly transforming powder raw materials into granular products that meet user requirements, without the need for any intermediates or additives. After granulation, the product has uniform particle size, significantly increased packing density, improved flowability, controlled dust flying, reduced powder waste, easy storage and transportation, and can control solubility, porosity, and specific surface area. Can be directly used for tablet pressing or capsule filling. Especially suitable for granulation of drugs that cannot be granulated by traditional wet granulation and are unstable under humid and hot conditions. The dry granulation process can replace the assembly line input of wet granulation, saving manpower, material resources, and financial resources, and is a new type of energy-saving and environmentally friendly equipment. This machine is easy to install, disassemble, and clean.

Food industry -- granules for condiments and spicy condiments, granules for Dim sum preparation, granules for health food, granules for convenience food, condiments, dairy products, and health products
Chemical industry and others - cosmetics, pesticides, chemical industry drugs, animal feed, detergents.

Introduction to the new structure of this dry process:

The Guolang GLZ300 fully automatic dry granulation machine has a novel design: a water cooling system (which can be configured separately according to the heat of the material), an electrical monitoring system, a reasonable structure, stable and reliable performance, and no tetrafluoroethylene powder or metal substances in the particles. It is well made, adopts German production technology, equipped with an automatic feeding system, easy to assemble, disassemble, clean and maintain, and meets the requirements of various domestic GMP quality certifications.

The machine consists of lifting, feeding, tablet pressing, granulation, hydraulic, cooling, frame, outer sealing, and electrical components.

① The lifting part is achieved by hydraulic lifting cylinders to raise and lower the feeding mechanism, controlled by limit switches, and interlocked with feeding, pressing, and whole granule.

②The pressure section is supplied with oil to the oil cylinder by an electric vane pump, which is stabilized by an accumulator. The upper and lower pressure limits are set using an electric contact pressure gauge.

③ The tablet press is driven by an electric motor to drive a cycloidal pinwheel reducer, which rotates the transmission shaft and drives the relative rotation of the two pressure wheels to work together with pressure, compressing the powder into flakes. According to the compressibility of different materials, the speed of the pressure roller can be infinitely adjusted (variable frequency speed regulation).

④ The whole granulation part is driven by a variable frequency speed regulating motor to rotate the granulation blade, shaping the sheet material into the required particles and discharging them in the mesh.

⑤The feeding part is driven by an electric motor to pre press and degas the powder using a double cone screw with unequal pitch. According to the performance of different materials, the feeding speed can be infinitely adjusted (variable frequency speed regulation).

⑥ Cooling can be achieved by using tap water or cooling water, which is forcibly cooled on the surface of the pressure wheel through the HS-X32A bidirectional inner tube rotary joint via the shaft hole.

The electrical control component is a 380V power supply, consisting of electrical components and circuits such as frequency converters/PLCs/touch screens, which control the feeding, pressing, and granulation through stepless speed regulation.

This machine has a novel and reasonable structure, stable and reliable performance, low noise, and easy cleaning and maintenance.

1Improved the processing technology of granulation cage, adopting wire cutting for one-time forming

2. Improved the processing technology for installing mesh rings, making the production and assembly of mesh screens more convenient.

3Improved the form of the force tool for the whole particle section to increase the yield of particles without clogging.

4. Improved the installation form of the screening device (using quick opening, no screw connection), previously fixed with screws (due to the small size of the screws, it is difficult to disassemble and clean each time, and the screws are prone to slipping teeth). After the improvement, it is easy to assemble, disassemble, and clean

5. Add a reducer to the granulation section, and use a motor that does not work at low frequencies and will not get stuck

6More suitable for large-scale production use, with 5350 grams available for experimentation and continuous operation.

7. The entire machine's tabletop is machined flat, so that all components mounted on the tabletop are in the same horizontal plane. When the machine is pressing, it works smoothly and without vibration at a fast speed, thus increasing production.
