Pelletizing machine

Abstract

The invention belongs to the field of pelletizing equipment, and especially relates to a pelletizing machine. According to the pelletizing machine, a storage hopper is arranged above a pedestal; a feeding device is arranged on the lower part of the storage hopper; a compacting mechanism is arranged in the feeding device; a left pelletizing rolling cutter and a right pelletizing rolling cutter are arranged under the feeding device, wherein the rotating direction of the left pelletizing rolling cutter and the rotating direction of the right pelletizing rolling cutter are opposite to each other; the pelletizing rolling cutters are driven by a drive motor; a grading screen is arranged below the pelletizing rolling cutters; a waste material recycling bin is arranged under the grading screen; the waste material recycling bin is arranged on the pedestal; a material returning screw conveyer is arranged in the waste material recycling bin; a bucket elevator is arranged between the material returning screw conveyer and the storage hopper; the feeding device comprises a feeding hopper and a feeding pipe; the compacting mechanism comprises a rotating shaft and compacting slices arranged on the rotating shaft; the compacting slices are arranged on the rotating shaft in the feeding pipe; and the rotating shaft is connected with the drive motor. The pelletizing machine is high in pelletizing efficiency; and the rotating shaft and the compacting slices are capable of providing raw materials with certain pressure, so that it is beneficial for subsequent pelletizing operation, and pelletizing efficiency is increased.

Description

technical field [0001] The invention relates to the field of granulation equipment, in particular to a granulator. Background technique [0002] A granulator is a molding machine that can make materials into specific shapes. Widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. According to the structure and working principle, it can be further divided into CF type rotary steel belt molten material granulator (steel belt granulator for short), flat twin-screw extruder, rotary drum drying tablet machine, double-roll dry granulator (short for short-circuit granulator). Roller granulator) and other disc granulators are volumetric metering feeding equipment, which can evenly and continuously feed materials to the next process, and can withstand large warehouse pressure. As a feeding equipment for fine-grained materials, it is suitable f...

AI Technical Summary

Problems solved by technology

[0003] The traditional granulation knife assembly is cylindrical, and the size of the inlet and outlet is the same. If the material returns, the material will be blocked, and continuous production cannot be carried out; in addition, the granulation knife is arranged axially on the knife seat , after being in contact with the material, the extrusion effect is not good, and the particles formed after extrusion are uneven and not full enough
