I. Overview:
In a dispersion where solid powder and liquid coexist, predominantly in a solid phase.,Utilize the self-adhesive properties of the particulate matter(Or with added binder),By enforced means(Such as extrusion, gravity, centrifugal force, mechanical force, and air jet thrust.)Bond the basic particles of solid powder material together.AddLarge and uniformly shaped granules form a dense particle cluster. The wet granulation system consists mainly of mixing (kneading), granulation, drying, and auxiliary equipment. After mixing (kneading), the powdered material enters the granulator to form wet products of the required particle size, which are then dried to produce granular finished products, thereby achieving the granulation goal.
Two,SETTwin-screw extruder granulators are divided into front discharge and side discharge types. The granulation diameter of the front discharge type is generally1.5-12mmBetween options, side discharge granulation diameter is generally0.7-2.0Select particles with a cylindrical shape, granulation rate ≥95%The discharge outlet is equipped with a particle cutting device, allowing the long strips to naturally form into individual granules after drying. Additionally, the front end of the equipment features a water cooling unit, which lowers the temperature inside the tube to speed up the discharge process.
Primary Advantages:
III.Due to the granulation process being completed in a wet state for powdered materials, the operating conditions for granulation and subsequent processes (such as drying, packaging, etc.) are significantly improved. Generally, it can reduce the dust飞扬 on-site.90%Above. Granulation can prevent phenomena such as caking, bridging, and pulsation that are common in powdered products, avoiding secondary contamination during use and significantly improving the physical properties of the product. Generally, the bulk density of granulated products is much higher, thus saving space for transportation, storage, and packaging. For products with multiple components, granulation can prevent segregation of the components, ensuring the quality of the composite product.
