First, LGX series dry granulator - equipment overview


The dry granulator utilizes the crystal water of the material itself, and relies on the principle of mechanical extrusion to directly form the raw material powder without the binder and water for tableting, tableting, sheeting, granulation and granulation. Granulation equipment. The irregular particles are formed to complete the physical change process from the powder to the particles. The dry granulator has the characteristics of simple process, large production batch, easy cleaning and maintenance. Widely used in medicine, food, chemical and other industries.

The dry granulator is mainly divided into a granulating device and a power device, and the two parts are completely isolated in space. The granulating device is mainly divided into 10 modules: 1 horizontal feeding system; 2 screw feeding system; 3 rolling system, pressure roller; 4 pre-pressing system; 5 crushing system 6 sampling port; 7 two-stage screening granulation System; 8 sampling ports; 9 particle outlets; 10 racks

During the dry granulation process, the dry powder or fine crystalline material is pressed into a sheet by a press roll, and the quality of the sheet determines the quality of the final granule. The dry granulator uses the latest roll control technology. The equipment's control equipment can adjust the fluctuation of any physical properties between different materials and different batches of the same material (such as local unevenness), making the process parameters of dry granulation. (such as throughput, sheet density, rolling pressure, speed, etc.) can be precisely and repeatedly adjusted to efficiently produce high quality particles.

In addition, there is a clear, modular separation between the dry granulator feed and the roll treatment process. The screw feed system directly delivers the powder to the press roll so that the roll press process does not affect the initial press of the screw feed system. process.

The dry granulator mainly exhibits good adaptability to different materials, compact structure, quick disassembly and cleaning, high initial molding rate, and small differences in density, hardness, solubility and color of the finished pellets, and high degree of automation.


2, LGX series dry granulator - equipment features

1. The cantilever design of the whole machine is domestically leading, with the characteristics of convenient observation and easy cleaning. The processing zone is completely isolated from the power transmission zone and has a neat appearance, which is easy to disassemble and clean, and realizes clean and closed production from powder to granule.

2. The pressure transmission structure adopts oil seal, special sealing of silicone pressure roller and air isolation (drain shaft structure) to effectively isolate the transmission part from the working part, and it is convenient to disassemble, maintain and replace;

3. Adopting twin-screw feeding, there is a vacuum degassing device at the feeding end, the feeding is uniform and compact, and the uniformity and yield of the sheet strength are improved;

4, water-cooled pressure roller, the structure of the inlet and outlet is built-in, the test material will not heat up during the extrusion process, affecting the material performance.

5, transparent work area, making observation more direct and convenient, easy to control and adjust the quality of the tablet. Seals are sealed with two or more stages to ensure cleanliness and prevent contamination.

6. The system structure is reasonable in design, the man-machine interface is safe, reliable and fast, the process flow ratio is reasonable, and the production operation is reliable. The whole machine is made of stainless steel, and the contact material can be made of 316 material, which meets GMP and FDA requirements.
