A high-hardness raw ore stripping type automatic crushing device and its application method

Abstract

The invention discloses a high-hardness raw-ore stripping type automatic pulverizing device. The device comprises a first box body, a four-claw clamping disc and a clamping disc sliding block, a fueltank is fixedly installed on the top of the first box body, and the right side of the fuel tank is provided with a water tank which is fixedly installed on the top of the first box body. The device has the advantages that the structure is simple, the operation is simple and convenient, the current problem of high-hardness raw ore pulverizing is solved, rapid temperature reduction is conducted by spraying water mist after high-hardness raw ores are flamed and heated, so that the internal molecular structures of the high-hardness raw ores are changed through the principle that expansion is caused by heat and contraction is caused by cold to allow the raw ores to be stripped layer by layer to be easily pulverized, fuel and water can be automatically added, the whole operation is automated, manual operation is not needed, and therefore the efficiency is greatly improved.

Description

technical field [0001] The invention relates, in particular, to a high-hardness raw ore stripping type automatic crushing device and a use method. Background technique [0002] At present, beneficiation is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation and other methods are used to separate useful minerals from gangue minerals. And to separate various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, and obtain raw materials for smelting or other industries. The following three most basic technological processes, the order of which is preparation, sorting, and treatment. The preparation is divided into crushing, grinding, screening and grading, and ore washing. The crushing is the particle size extracted from the mine. It is the process of crushing ore blocks of 500-1500mm...

[0002] At present, beneficiation is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation and other methods are used to separate useful minerals from gangue minerals. And to separate various symbiotic (associated) useful minerals from each other as much as possible, remove or reduce harmful impurities, and obtain raw materials for smelting or other industries. The following three most basic technological processes, the order of which is preparation, sorting, and treatment. The preparation is divided into crushing, grinding, screening and grading, and ore washing. The crushing is the particle size extracted from the mine. It is the process of crushing ore blocks of 500-1500mm to a particle size of 5-25mm. The methods include crushing, crushing, and splitting, etc. Generally, it is carried out in three stages: coarse crushing, medium crushing, and fine crushing. The efficiency of ore crushing is very low. Due to the high hardness of the raw ore, if a tool with a general hardness is used for crushing, it is easy to wear and consume a lot. If the tool is used with a high hardness, it will increase the cost on the one hand, and on the other hand, due to the high hardness of the tool, the toughness will inevitably be low. It is easy to cause chipping during the crushing process, which will aggravate the cost. At present, if there is no special need for high-hardness raw ore, it is generally not beneficiated, and it will be discarded directly. However, the discarded high-hardness raw ore contains A large number of resources have not been utilized, so now a special device for crushing high-hardness metal raw ore is needed
