Powder pulverizer

Abstract

The invention discloses a powder pulverizer. The powder pulverizer comprises a casing, a motor, a primary pulverizing device, a pulverizing barrel, a pulverizing core and a fan, wherein the motor is fixed on the casing; the pulverizing barrel is arranged above the motor; the fan is arranged at the bottom of the pulverizing barrel; the upper end of the fan is connected with the pulverizing core; the upper end of the pulverizing core is connected with the primary pulverizing device; the pulverizing barrel and the pulverizing core rotate relatively, the pulverizing barrel and the pulverizing core are conical, but the conicity of the pulverizing barrel is smaller than that of the pulverizing core, and the pulverizing barrel and the pulverizing core are coaxially arranged. The powder pulverizer can pulverize large materials by the aid of a knife or a hammer, the adaptability to raw materials is improved, the materials can be pulverized by means of the conical pulverizing barrel and the conical pulverizing core which rotate relatively, the particle fineness is high, the pulverizing speed is high, and discharge of the materials is facilitated.

Description

technical field [0001] The invention relates to the field of pulverizing machinery, in particular to a powder pulverizer. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices. It achieves the purpose of the pulverizer in the form of high-speed impact. It uses wind energy to form powder at one time, canceling the traditional screening procedure. It is mainly used in various industries such as mines and building materials. [0003] Existing pulverizers usually use knives, hammers, or extrusion to achieve material crushing. There are certain requirements for the size of the input materials, and repeated crushing is easy to cause energy waste. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a powder pulverizer, which is crushed by a primary crushing devi...
