Factory location: Huzhou, Shandong Province, China
Hourly output：20,000-25,000 pcs (Standard bricks)
Raw material: Clay, Shale, Coal Gangue, Cinder mixtures

The raw materials of this brick project are complex. Four raw materials of shale, coal gangue, cinder and clay are mixed to make bricks. They are fed separately through four box feeders, and then crushed by hammers at the same time. Then they are screened by two rolling screens and the coarse materials are sent back to hammer crusher for secondary crushing. The fine materials enter into double shaft mixer and mixing with water, and then are sent to the aging warehouse through the conveyor belt. The raw materials are aged in the aging warehouse and enter into brick making workshop. After being crushed by double roller crusher again, then enter into mixer and water mixing, and finally feed into double stage vacuum extruder, the mud strips are extruded by vacuum extruder, then cut into strips and billets by column cutter and billet cutter, then passed auto grouping and robot stacking onto kiln cars.

This project is with typical process of making bricks by multiple raw materials. Four kinds of raw materials are crushed and aged to make bricks. The process is simple and the investment cost is low. The ageing warehouse is a one-way fetching warehouse for hydraulic multi-bucket excavators. It occupies a small area and has higher applicability to projects with restricted terrain.

The project adopts tunnel kiln with cross-section of 7.2m, one tunnel for drying bricks and one for baking bricking, with an annual output of 160-180 million pieces (equivalent to Chinese standard bricks).
