Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] An ultrafine pulverizer disclosed in the embodiment of the present invention improves the crushing efficiency of the ring gear and the hammer head on the material, increases the impact of the high-speed airflow on the material, and promotes the collision and friction between the materials, thereby improving the crushing effect and saving crushing Processing time is improved, equipment durability is improved, and maintenance costs are reduced.

Abstract

The invention discloses an ultrafine pulverizer. A gear ring of a pulverizing mechanism of the ultrafine pulverizer is formed by connecting and splicing a plurality of identical gear ring arc sections end to end; inclined teeth inclining towards the axial direction of the gear ring are arranged in the arc sections of the gear ring; alloy strips are arranged on the inclined teeth by oxygen welding; a plurality of grooves are formed in the alloy strips; a dentoid structure is arranged on one side, facing to the gear ring, of each hammerhead; the dentoid structures are inclined teeth inclining towards the normal direction of a wearproof tray; and the inclination directions of the inclined teeth on the hammerheads are opposite to those of the inclined teeth on the gear ring. According to the ultrafine pulverizer, with the adoption of the inclined tooth structures of the gear ring and the hammerheads, the impact of a high-speed air flow on materials in the pulverizer is improved, and the collision and the friction among materials are increased, so that the pulverizing efficiency and effect are improved effectively; the yield by the pulverizer is increased; the abrasion performances of the hammerheads and the gear ring are improved with the adoption of the alloy materials; the service life of the hammerheads and the gear ring is further prolonged; and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of material crushing equipment, in particular to an ultrafine pulverizer. Background technique [0002] The existing ultrafine pulverizer mainly consists of a pulverizing mechanism and a grading mechanism, wherein the pulverizing mechanism includes a pulverizing turntable, a hammer head installed on the pulverizing turntable and distributed uniformly along the circumference, and a ring gear surrounded by the periphery of the pulverizing turntable, the pulverizing turntable and the teeth. There is an air inlet channel between the rings, and the crushing turntable is driven by the main shaft to rotate at high speed; the classification mechanism includes a shunt cover and a classification impeller. The shroud and the dust collection shell, the shunt cover is composed of an outer cylinder and an inner cylinder arranged concentrically, there is a gap between the inner cylinder and the outer cylinder, the outer cylinder is ...
