Problems solved by technology

Although the invention adopts the form of gear meshing to extrude the material, it has higher requirements for the characteristics of the material
For example, for materials with many fibers and easy arching and blockage, the combined structure of the invention is not conducive to the granulation of the materials, and will also cause a backlog of blockage, thereby increasing the working pressure between the workpieces and causing irreversible damage to the workpieces. increase maintenance cost
[0006] To sum up, the current ring die granulators on the market still have problems such as fast wear and short service life of the ring die and pressure rollers when they are working. more serious wear

Abstract

The invention provides a ring-die granulator. The ring-die granulator comprises a frame, a feeding part arranged on the frame, a die-roller system, a motor used for driving the die-roller system, a discharge outlet, and a granulating chamber arranged outside the die-roller system, wherein the die-roller system comprises a ring die with internal teeth, and pressure rollers which have external teeth and are arranged inside the ring die. According to the invention, the ring die rotates clockwise at a certain rotational speed around a hollow shaft of the granulator, and the pressure rollers start to rotate clockwise by utilizing the force of friction between the ring die, the pressure rollers and materials, so the materials are extruded and compressed; meanwhile, a discharge hole of the ring die is substantially improved, so the granulator is suitable for rolling compaction of various materials; thus, granulation efficiency is greatly improved, and machine halt factors like blockage of the materials are reduced.

Description

technical field [0001] The invention relates to a ring die granulator and its working method and application, belonging to the technical field of granule forming processing equipment. Background technique [0002] The working principle of most of the ring die granulators currently on the market is that the sawdust, straw and other materials processed by the feeder are sent by the material guide mechanism to the working area between the ring die and the pressure roller in the granulation chamber mechanism. The mold rotates clockwise at a certain speed, and the pressure roller starts to rotate clockwise with the help of the friction between the ring mold, pressure roller and the material in the working area. Extrude through the die hole, cut off by a cutter to form the desired granules. [0003] Announced a kind of wood processing machine as Chinese patent CN200945426. The machine includes at least two rotatable rolling rollers axially symmetrical along the drive shaft. Ther...
