Product Overview :
This series of extrusion granulators consists of a hopper, a barrel, a screw feeding section, a screw compaction section, a rotary cutter, a template, a pressure plate, a frame, a bearing system, a transmission system, and an electrical control system. After the powdered material is mixed with the binder, it enters the granulator through the feeding hopper, and is compacted by the screw compaction section before being extruded from the template to form particles in the shape of columns or strips. And according to the characteristics of the user's materials, it is equipped with forced feeding and particle cutting devices. The modified casing is widely used in
Summary:
In a dispersion where solid powder and liquid coexist and the solid phase is the main component, the self adhesiveness of the dispersion (or the addition of a binder) is utilized to force the basic particles of the solid powder to adhere and increase in size through methods such as compression, gravity, centrifugal force, mechanical force, and airflow impact. And form a uniform and concentrated particle group with a certain shape and particle size. The complete set of wet granulation equipment mainly consists of mixing (kneading), granulation, drying and its auxiliary system equipment. After mixing (kneading) the powder, it enters the granulator to form a wet product with the required particle size, and is dried to obtain a granular finished product, thus achieving the purpose of granulation.
The DLG type single screw extrusion granulator is divided into front discharge type and side discharge type. The diameter of the front discharge type granulator is generally selected between 1.5-12mm, and the diameter of the side discharge type granulator is generally selected between 0.7-2.0. The particle shape is cylindrical, and the granulation rate is ≥ 95%. The discharge port is equipped with a particle cutting device, and the long strip naturally forms particles after drying. The front end of the equipment is also equipped with a water cooling device to reduce the temperature inside the pipe and speed up the discharge.
Application scope:
Widely applicable to products that require granulation in industries such as rubber additives, food additives, plastic additives, powdered activated carbon, catalysts, feed, pesticides, dyes, pigments, daily chemicals, pharmaceuticals, etc.
Main advantages:
Due to the wet granulation process of powdered materials, the operating conditions for granulation and subsequent processes such as drying and packaging are greatly improved. Generally, it can reduce on-site dust flying by more than 90%. By granulation, it is possible to avoid the phenomena of agglomeration, bridging, pulsation, and other factors that may affect the use of powder products. At the same time, it avoids secondary pollution caused by powder during use, greatly improving the physical properties of the product. In general, the stacking density of granulation products is significantly increased, which can save transportation, storage, and packaging space. For multi-component composite and mixed products, granulation can avoid component segregation and truly ensure the quality of composite products.
