Description

Technical Field

[0001] The utility model belongs to the technical field of flame retardant production, in particular to a granulator. Background Art

[0002] Flame retardant masterbatch, also known as flame retardant masterbatch, is a type of product produced to achieve the fire protection requirements of plastics and rubber products. With the advancement of science and technology and the improvement of living standards, polymer materials, especially synthetic polymers such as plastics and rubber, are becoming more and more important in people's lives, and their applications are expanding year by year. In the manufacturing process of flame retardant masterbatch, a granulator is required. The granulator is an industrial equipment mainly used to make powdered or granular raw materials into particles or granular substances of specific shapes.

[0003] The utility model patent with patent application publication number 201821409995.7 discloses a granulator, including a head. The head is provided with a sandwich structure containing a circulating water system. The head is provided with a water inlet and a water outlet. By passing circulating water into the sandwich structure, the temperature of the head can be reduced to ensure the normal fullness of the discharged material, and the life of the equipment can be avoided from being affected by the heating of the head, so that the production is continuous, the equipment utilization rate is improved, and the production cycle is shortened. In addition, the screw used in the utility model is matched with the corresponding cutter head, and different screws and cutter heads can be replaced as needed.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that when the raw materials are added into the granulator, it lacks the ability to dry the raw materials. If the humidity of the raw materials is high, it is necessary to dry the raw materials relatively by an external dryer and then dry them by the granulator, thereby affecting the production efficiency of the flame retardant masterbatch. For this reason, we propose a granulator. Utility Model Content
