Description

TECHNICAL FIELD

[0001] The utility model relates to the field of domestic waste incineration, and specifically relates to a crusher for domestic waste incineration power plant slag. BACKGROUND

[0002] The slag of a domestic waste incineration power plant is a solid waste left over from the incineration process, usually including incompletely combusted organic matter, inorganic components, and some metal residues. The composition of the slag is usually complex, mainly including moisture, ash, heavy metals (such as lead, cadmium, mercury, etc.), minerals, etc. Through composition analysis, the impact on the environment and the resource recovery potential can be evaluated. Some of the slag can be used for building material manufacturing, such as making cement, concrete, or bricks, etc. Even the metal components can be recovered. After appropriate treatment, the slag can also be used as a new type of building material, reducing the dependence on natural resources.

[0003] The existing crusher for domestic waste incineration power plant slag is mostly a hammer crusher, which mainly relies on high-speed rotating hammers to impact and crush the slag. The slag is broken by the impact of the hammers and the mutual collision between the materials. The uneven wear of the hammers and the uneven distribution of the materials in the crushing chamber can easily cause the size of the discharged particles to be uneven, affecting the subsequent treatment and utilization of the slag. Therefore, we propose a crusher for domestic waste incineration power plant slag. SUMMARY
