Description

Technical Field

[0001] The utility model relates to the technical field of slag crushing, in particular to a slag crusher. Background Art

[0002] The slag from the municipal solid waste incineration power plant is mainly an inhomogeneous mixture of stones, sand, glass, ceramics, ash and a small amount of unburned garbage. After crushing and sorting, the slag has stable chemical properties, good durability and high strength. The slag is a non-toxic general waste and can be directly landfilled or processed. The slag after technical treatment is suitable for making unburned bricks or other building materials and has a certain recycling value.

[0003] During the secondary treatment of the slag from the primary treatment, the slag is evenly and continuously fed into the conveyor belt through the feeder under the drum sorting screen. The self-unloading belt-type electromagnetic iron remover arranged on the upper part of the conveyor belt performs secondary magnetic separation on the slag to absorb the ferrous metal in the slag. After the secondary magnetic separation, the two parts of the discharge are: ferrous metal and slag. The slag continues to enter the secondary crushing process, and the ferrous metal enters the tertiary crushing.

[0004] Slag crushers are used to crush the slag after secondary magnetic separation, and the slag treatment industry currently uses hammer crushers for slag crushing. The working surface of the hammer head in the current hammer crusher is relatively smooth, the blunt surface has little impact and the hammer head is integrally processed and formed. When the working surface of the hammer head is worn, the entire hammer head needs to be replaced, which is costly. Utility Model Content
