Embodiment Construction
[0020] The pressure gas crushing method provided by the present invention will be further described below in conjunction with the examples.
[0021] During implementation, the ore is placed in the airtight device, and the pressure gas is passed into the airtight device, so that the gas pressure in the airtight device is greater than the compressive strength of the ore, and the ore is broken at the moment of opening the airtight device. Preferably, after the gas pressure in the airtight device is greater than the compressive strength of the ore, the pressure can be maintained for a period of time, so that the pressure gas can fully fill the internal space of the ore, so that a good ore breaking effect can be obtained in a more economical and reasonable way.
[0022] Each type of ore has different internal void sizes, different ore compressive strengths, and the ore humidity and temperature are different. Therefore, under the condition of certain ambient temperature and humidity,...

The invention relates to a pressure gas ore-crushing method and a pressure gas ore-crushing device, and belongs to the field of ore crushing. The pressure gas ore-crushing method adopts the technical scheme as follows: ore is placed in a closed device, a pressure gas is introduced into the closed device to make the gas pressure in the closed device greater than ore compressive strength, and ore crushing can be completed at the instant moment of opening of the closed device. The pressure gas ore-crushing device adopts the technical scheme as follows: the pressure gas ore-crushing device includes a compressor and an ore storage tank, the compressor is connected with the ore storage tank by a gas pipe, the ore storage tank is provided with a cover plate capable of being opened, and the cover plate is connected with the ore storage tank in a manner of seal connection. According to the pressure gas ore-crushing device, the popcorn theory is imitated, the ore is placed in the closed device, the pressure gas is introduced into the closed device for ore crushing, and the pressure gas ore-crushing device is simple, effective, and low-cost. In addition, the ore-crushing location is not limited by the place, and the pressure gas ore-crushing device is not like a wet ball mill needing water resources.
Description
technical field [0001] The invention relates to a pressure gas crushing method and a pressure gas crushing device, which belong to the field of ore crushing. Background technique [0002] At present, with the application of various mechanical crushing equipment in our country, there are many types of crushing equipment for different products. Taking the crushing of vanadium-titanium magnetite in Panxi area as an example, the traditional crushing methods use cone crushers, jaw crushers, ball mills, tube mills, etc. The equipment is complex, and the consumption of liners, balls, and tubes is large. , ore crushing cost is higher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple, effective and low-cost pressure gas crushing method. [0004] Correspondingly, another technical problem to be solved by the present invention is to provide a simple, effective, and low-cost pressure gas crushing device. [0005] ...
