Description
Technical Field
[0001] This utility model belongs to the field of mixing equipment technology, and more specifically, it relates to a mixing equipment for making bricks from waste incinerator slag. Background Technology
[0002] In the field of waste treatment and resource utilization, waste incineration slag brick making is an important treatment method. In the production process of waste incineration slag brick making, the mixing process is one of the key steps affecting the quality of the brick. It is necessary to fully and evenly mix the slag with other brick-making raw materials (such as cement, additives, etc.) to ensure that the final brick has the required physical and chemical properties.
[0003] However, existing mixing equipment for brick making from waste incinerator slag has many shortcomings in structure and function. In terms of feeding, traditional equipment often lacks effective screening components, which may result in the raw materials entering the mixing chamber being mixed with particles that are too large or do not meet the requirements. These impurities not only affect the uniformity of mixing, but may also have an adverse effect on subsequent brick making processes, reducing the overall quality of the bricks. During the mixing process, some equipment has a simple mixing structure and low mixing efficiency, making it difficult to achieve the ideal mixing effect of raw materials in a short time, which increases production time and energy costs.
