Abstract

The utility model provides a machinery feeding type airflow crusher which is characterized in that a mechanical feeder arranged on the top of a crushing chamber is used to replace an existing airflow feeding spray nozzle, and the discharge port of the mechanical feeder is over against the top face of a classification-rotor. The materials are flung to eddy airflow to be crushed by the rotary classification-rotor. Compared with the prior art, the utility model has the advantages of continuous and homogeneous feeding, few abrasion, non-air source consumption, stable air-solid ratio in the crushing chamber, etc. The utility model is suitable for the superfine crushing of non-metal minerals.

Description

Machinery feeling type air flow grinder

The utility model belongs to particularly a kind of airslide disintegrating mill of mechanical loading of a kind of improved granule materials pulverizer.

Existing airslide disintegrating mill is mainly by pulverizing chamber, air-flow nozzle, and reinforced nozzle and outlet are formed.Its operation principle is to utilize a plurality of high velocity air nozzle ejection supersonic airstreams, in circular pulverizing chamber, produce high speed whirlpool circulation, allow send between granule materials in the whirlpool circulation and pulverizing chamber inwall and the granule materials and bump, rub and shear through reinforced nozzle, the oneself who realizes no medium pulverizes, and utilize centrifugal force to make the interior pulverized particle of circulation by quality size natural separation, corase particles is thrown toward outer circulation to be continued to pulverize, and just is transported to classification blanking the finished product classifying equipoment with air-flow from outlet near the particulate at center.Find that in use this pulverizer has following weak point: owing to adopt the reinforced nozzle quick abrasion of air-flow feeding, the life-span is short, and expends gas, and the gas-solid ratio in the pulverizing chamber is stable inadequately, influences crushing effect.

The purpose of this utility model is to overcome existing air-flow and pulverizes above-mentioned shortcoming, is further improved on " being provided with the airslide disintegrating mill of classification rotor " of patent applied for, and a kind of mechanical loading formula airslide disintegrating mill simple in structure is provided.

Above-mentioned task is achieved in that identical with prior art, and this machine includes pulverizing chamber, air-flow nozzle, classification rotor and outlet, and its improvements are that a mechanical charge is set at the top of pulverizing chamber, and its discharging opening is over against the end face of classification rotor.

By above-mentioned improvement, material is the end face that mechanically adds to the classification rotor, by the classification rotor that rotates material is thrown in the vortical flow then and pulverizes.Therefore, seldom there is wear problem, with the reinforced wearability that can improve feeding device greatly of comparing of air-flow, and it is reinforced even continuously, not loss source of the gas, make the gas-solid ratio in the pulverizing chamber stable, reached best crushing effect, adopt the reinforced shortcoming of reinforced nozzle thereby overcome existing airslide disintegrating mill effectively.

Below in conjunction with accompanying drawing to structure of the present utility model to further introduction.

Fig. 1 is the schematic diagram of a kind of concrete structure of the utility model.

Fig. 2 is the vertical view of classification rotor (7) among Fig. 1.

As shown in drawings, on the circumference of pulverizing chamber (4), be provided with a plurality of air-flow nozzles (5), outlet (6) is set at the center of its Lower Half, be arranged on the top of outlet (6) by motor (1) by the classification rotor (7) of rotating shaft (2) drive.Mechanical charge (8) is arranged on the end face of pulverizing chamber (4), and its discharging opening (3) is located at the end face center of the center of pulverizing chamber (4) over against classification rotor (7), and rotating shaft (2) is passed discharging opening (3) and is connected with classification rotor (7).Mechanical charge (8) can adopt mechanical type doser commonly used, as plate feed, and vibra feeder and screw feeder etc., but preferably adopt screw feeder, it has continuous even feeding and the few advantage of noise.For the ease of classification rotor (7) material is got rid of to vortical flow, prerotation vane (9) can be set at the end face of classification rotor (7).

The utility model is applicable to ultra tiny pulverizing nonmetallic mineral.
