Problems solved by technology

At home and abroad, airflow pulverizers, roller press pulverizers, media motion pulverizers, mechanical impact pulverizers, etc. are mainly used to pulverize materials through impact, shearing, friction and other mechanical forces. The equipment structure is complex. High energy consumption per unit product, high wear and tear, low production capacity, backward automatic control ability, low technology integration, poor matching, the fineness of the crushing level is 40-10μm (380-1250 mesh); energy consumption is 100-160KWh / T; Unit output 1.5~0.05T / h
Some even have big vibrations, loud noises, and a lot of dust, making the crushing environment daunting

Embodiment 1-3

[0049] River sand with a medium Mohs hardness of less than or equal to 3mm is used as a raw material to carry out large-scale industrial production of fine powder according to the process flow and feature (2) of the above schematic diagram 1.

[0050] The raw material enters the micro-opening material box A-3 from the raw material conveyor A-2, and the iron remover A-1 is installed on the raw material conveyor to remove iron. After the raw material enters the micro-opening material box A-3, it is automatically processed The flow fine pulverizer A sucks and pulverizes, and automatically feeds the pulverized material into the micro-opening material box of the secondary flow fine pulverizer A, and is automatically sucked and pulverized by the secondary flow fine pulverizer A, and automatically puts The pulverized material is input into the micro-opening material box of the three-stage follow-up fine grinder A, and is automatically sucked and crushed by the three-stage follow-up fi...

Abstract

A method and pulverizer for industrially preparing superfine powder is disclosed. Said pulverizer is composed of iron remover, 1-3 large superfine pulverizing units connected serially, classifier for classifying the powder, and packing unit. Its advantages are high productivity (30-40 T / hr), low energy consumption and environment friendly.

Description

technical field [0001] The invention relates to the field of powder engineering, in particular to a method for industrialized large-scale production of fine powder and a fine crushing device thereof. Background technique [0002] At present, the large-scale production of fine powder, such as the annual output of hundreds of thousands of tons or several million tons of each production line, and the matching of large fine grinding equipment (single machine annual output of hundreds of thousands of tons), have not been reported so far. At home and abroad, airflow pulverizers, roller press pulverizers, media motion pulverizers, mechanical impact pulverizers, etc. are mainly used to pulverize materials through impact, shearing, friction and other mechanical forces. The equipment structure is complex. High energy consumption per unit product, high wear and tear, low production capacity, backward automatic control ability, low technology integration, poor matching, the fineness of ...
