Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] see figure 1 , the device includes a crushing chamber and a Venturi feeding system. The shape of the crushing chamber is octagonal with rounded corners. The cross section of the crushing chamber is rectangular. Inlets forming a diagonal venturi feed system, see figure 2 . The crushing chamber is connected to the Venturi feeding system. The inlet end of the Venturi feeding system is equipped with a Venturi nozzle. The top of the middle part of the Venturi feeding system is provided with a feeding hopper. A number of intermediate rings are provided with eight nozzles on the intermediate ring, and a separation area and a disch...

Abstract

The invention relates to the technical field of a mechanical crushing device and particularly relates to a novel structure device of a superfine powder crushing chamber and a crushing method of the novel structure device. The novel structure device comprises a crushing chamber and a Venturi feeding system, and is characterized in that the crushing chamber is in a shape of an octagon with a circular bead; the section of the crushing chamber is rectangular; the angle direction of a feeding hole of the crushing chamber is diagonal to the section of the crushing chamber, so that a diagonal inlet of the Venturi feeding system is formed. According to the novel structure device disclosed by the invention, the inlet of the Venturi feeding system is changed from a tangent type into a diagonal type so that the feeding angle is improved; the Venturi feeding system is also combined with a pressure balancing system on a Venturi hopper, so the feeding effect is remarkably improved, and backflow phenomenon is eliminated; therefore, feeding and particle acceleration can be implemented by adopting the same pressure; the utilization rate of an air source is greatly improved; the crushing chamber is in the shape of the octagon with the circular bead, so air flow can be thinned as far as possible; the time and space required for accelerating particles to a critical speed can be reduced; the production effect is optimized; the yield is increased; air consumption is reduced.

Description

[technical field] [0001] The invention relates to the technical field of crushing mechanical devices, in particular to a novel structure device of a superfine powder crushing chamber and a crushing method thereof. [Background technique] [0002] The airflow mill is a mechanical device that relies on high-pressure airflow to push the material to repeatedly collide and rub to crush inside the mill. It has the characteristics of wide application range and high fineness of finished products. There are mainly several types of jet mills used in my country's industry: flat jet mill, fluidized bed counter-jet jet mill, circulating tube jet mill, counter-jet jet mill, target jet mill, and spiral jet jet mill. grinder. [0003] The crushing chamber of the existing spiral airflow crushing device adopts a cylindrical structure, and the feeding pipe and the crushing chamber are tangentially fed. The added solid powder is inhaled and sprayed into the crushing chamber by the airflow at hi...
