Production line for producing brick making material by mixing building raw materials with sludge

The invention provides a production line for producing brick making materials by mixing building raw materials with sludge. The production line comprises a crushing mechanism, a sludge crushing mechanism, a sludge transferring mechanism, a mixing and crushing mechanism, a conveying mechanism and a control system, measuring the water content of the coal gangue, the slag ash, the sludge and the sludge, and then calculating the dosages of the coal gangue, the slag ash, the sludge and the sludge required by the water content of the mixed brick making material to be lower than 40%; the conveying amount of each raw material is adjusted through the control system, and the raw material ratio can be controlled with high precision, so that the water content process requirement of the brick making material is met; therefore, the waste of water resources caused by the use of tap water resources in the traditional brick making process is avoided; the sludge with the moisture content of about 80% from a sewage treatment pl
