Industry twin single screw extruder extrusion granulator

Industry twin single screw extruder extrusion granulator

In solid powder and liquid coexisting dispersions with solid phase as the main component, the self-cohesion (or external binder) of the dispersions is used to make the basic particles of solid powder adhere to each other and increase through forced methods (such as extrusion, gravity, centrifugal force, mechanical force, airflow impulse, etc.). It also forms a uniform and concentrated particle group with a certain shape and particle size. The wet granulation equipment is mainly composed of mixing (kneading), granulation, drying and auxiliary system equipment. After mixing (kneading) powder, it enters the granulator to form a wet product with the required granularity. The granular product is obtained by drying, thus achieving the purpose of granulation.

Single screw extrusion granulator is divided into two types: front discharging and side discharging. The diameter of front discharging granulator is generally 1.5-12 mm. The diameter of side discharging granulator is usually 0.7-2.0, and the shape of granule is cylindrical. The granulation rate is more than 95%. The outlet is equipped with a granule cutting device, the long strip is dried naturally into one section of granule, and the front end of the equipment is equipped with a water cooling device to make the pipe drop. The low temperature makes the discharging speed fast.

Scope of application
It is widely used in rubber additives, food additives, plastic additives, powdered activated carbon, catalysts, feed, pesticides, dyes, pigments, daily chemicals, pharmaceuticals and other industries to granulate products.

Main advantages
Because the granulation process of powder material is completed in wet state, the operation conditions of granulation and its follow-up process (such as drying, packaging, etc.) are greatly improved. Generally, it can reduce dust flying by more than 90%. Through granulation, the phenomenon of agglomeration, bridging and pulsation which easily occur in powder products can be avoided, and the secondary pollution caused by powder during use can be avoided, so that the physical properties of products can be greatly improved. Generally, the accumulation proportion of granulating products has been greatly increased, so the space of transportation, storage and packaging can be saved. For multi-component composite and mixed products, granulation can avoid component segregation, thus ensuring the quality of composite products.
