Granulator

Abstract

The invention provides a granulator. The granulator comprises a material extruding device, a cutter device and a driving device, wherein the material extruding device comprises a first support, a material extruding barrel, a sieve plate and a piston, the material extruding barrel is arranged on the first support, the sieve plate is arranged on the front end surface of the material extruding barrel, a plurality of through holes are uniformly distributed on the sieve plate, a feeding hole is formed at the upward side of the material extruding barrel, a feed hopper is arranged above the feeding hole, the piston is located in the material extruding barrel, the tail part of the piston is connected with the driving device for driving the piston to do reciprocating motion in the material extruding barrel, a circular arc shaped baffle plate is arranged on the piston, the length of the circular arc shaped baffle plate is more than that of the feeding hole, the cutter device comprises a fan-shaped cutter, a cutter rotating shaft and an electromotor, the fan-shaped cutter is arranged on the surface of the sieve plate, positioned outside the material extruding barrel, the circular center of the fan-shaped cutter is articulated with the center of the sieve plate, and the circular center of the fan-shaped cutter is connected with the electromotor by the cutter rotating shaft. The granulator has a simple structure, has no get-stuck phenomenon and can process uniform granules.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a granulator. Background technique [0002] In the production process of the magnetic ring, the first step is to use a granulator to make powder. The granulator generally uses the extrusion method to develop the wet powder into the required granules, and can also crush the block dry material into the required granules. At present, the most widely used granulator in the factory is the double-roller granulator, but this kind of granulator has complex structure, high processing precision, high cost, and needs to be equipped with a corresponding lubrication system, which is not easy to maintain. Moreover, this kind of double-roller granulator is often jammed due to too much filler. Moreover, the existing granulator has the problem of uneven particle size, which leads to uneven batching in the subsequent production of the magnetic ring. Contents of the invention [0...

At present, the most used granulator in the factory is the double-roller granulator, but this kind of granulator has a complex structure, high processing precision, high cost, and needs to be equipped with a corresponding lubrication system, which is not easy to maintain

Moreover, this kind of double-roller pellet machine often causes jamming due to too much filler.

Moreover, the existing granulator has the problem of uneven particle size, which leads to uneven ingredients in the subsequent production of the magnetic ring.
