►overview
In a dispersion where solid powder coexists with liquid and is mainly composed of solid phaseBy utilizing the self-adhesive properties of dispersed materials (or external binders), solid powder particles are forcibly bonded and enlarged to each other 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.
LKThe type of single screw extrusion granulator is divided into front discharge type and side discharge type. The diameter of the front discharge type granulator is generally in the range ofChoose between 1.5-12mm, and the diameter of the side discharge granulation is generally between 0.7-2.0. Choose a cylindrical particle shape with a granulation rate of ≥ 95%. The discharge port is equipped with a particle cutting device, and the long strip will naturally form particles one by one 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 advantage
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 the flying dust on siteMore 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.
