Abstract

The invention belongs to the technical field of solid grinders, and particularly relates to a non-sieve grinder which is formed in a way that a crushing element composed of a rotary hammer and a cutter blade combines a classification impeller. The non-sieve hammer knife type vertical grinder comprises a vertical barrel-shaped housing with a horizontal rotary table in the middle part, wherein a plurality of hammer knifes are fixed at the periphery of the horizontal rotary table; the classification impeller is mounted above the horizontal rotary table; a feed interface is formed on the side wall of the vertical barrel-shaped housing and at the position corresponding to the hammer knifes; an air inlet is formed on the side wall of the housing below the horizontal rotary table; and a discharge port is formed above the classification impeller. The grinder provided by the invention is characterized in that each hammer knife is composed of an upper hammer head and a lower hammer head, and a cutter blade between the upper and the lower hammer heads, and an included angle Phi is formed between the cutter blade and the connection surface of the upper and the lower hammer heads. The grinder has a superior crushing effect, not only can crush materials having a certain rigid, but also can radically crush materials having both toughness and rigidity.

Description

technical field [0001] The invention belongs to the technical field of solid pulverizers, in particular to a sieveless pulverizer combined with a pulverizing element composed of a rotary hammer and a blade and combined with a grading impeller. Background technique [0002] The hammer mill mainly relies on the impact to crush the material. The material enters the hammer mill and is crushed by the impact of the high-speed rotating hammer head. The crushed material obtains kinetic energy from the hammer head and rushes to the frame at high speed. The baffle sieve in the body, at the same time, the materials collide with each other and are crushed many times. The materials smaller than the gap between the sieves are discharged from the gap, and some larger materials are impacted by the hammer again on the sieve, and then ground. , squeezed and crushed to obtain the desired particle size product. The hammer mill has the characteristics of simple structure, large crushing rat...
