Extruding and pelletizing device for ceramic powder

Abstract

The invention discloses an extruding and pelletizing device for ceramic powder. The device comprises an extruding mechanism and a crushing mechanism, wherein the extruding mechanism comprises an extruding bin, and an extruding roller set which is arranged in the extruding bin; the extruding roller set comprises two extruding rollers which are arranged in parallel and oppositely rotated; fine powder conveyed to the surfaces of the two extruding rollers is extruded through the extruding bin to form blocky materials with proper hardness; the crushing mechanism comprises a crushing box, an arc-shaped friction sieving net which is arranged at the bottom part of the crushing box, and at least one crushing assembly which is arranged in the crushing box; the blocky materials conveyed into the crushing box can be collided and crushed through blades and a crushing hammer by circumferentially rotating along with a crushing shaft; in addition, the particles formed by colliding and crushing throughthe crushing hammer are extruded into a frictional clearance which is reserved between the crushing chamber and the arc-shaped frictional sieving net, and thus the particles formed by colliding and crushing can be pelletized by friction through the arc-shaped frictional sieving net.

Description

technical field [0001] The invention relates to the technical field of ceramic production equipment, in particular to a ceramic powder extrusion granulation device. Background technique [0002] In the current ceramic industry, it has been difficult to break through the recycling of residual powder in the production process, because in the existing equipment places such as spray tower bag filter, workshop environmental filter, press workshop, kiln grinding machine, etc. There will be residual tailing powder in the process, and the particle size of these tailing powders is different, so it cannot be directly recycled in production. Too large or too small powder will have a bad impact on product quality. If the tailing powder The raw materials are recycled in the traditional way through a series of traditional processes such as pulping-drying-granulation, etc. The recycling cost of this method is high, and manufacturers often choose to discard the tail powder directly.

[0002] In the current ceramic industry, it has been difficult to break through the recycling of residual powder in the production process, because in the existing equipment places such as spray tower bag filter, workshop environmental filter, press workshop, kiln grinding machine, etc. There will be residual tailing powder in the process, and the particle size of these tailing powders is different, so it cannot be directly recycled in production. Too large or too small powder will have a bad impact on product quality. If the tailing powder The material is recycled through a series of traditional processes such as pulping-drying-granulation in the traditional way. The recycling cost of this method is high, and manufacturers often choose to discard the tail powder directly.
