Brick extruding – once crushed, the clay is fed into a pug mill, folded together and then fed into an extruder. The air is then removed using a vacuum and the material is then compacted. There's a die in the machine which is brick-shaped, which the material is then pushed through. Following this, sections are then cut with saws or wires.
Fly Ash Brick Manufacturing Process. Fly ash brick manufacturing involves the following steps: 1. Mixing the Raw Materials. The raw materials, namely fly ash, cement, sand, and water are mixed in a pan mixer or a batching plant. The mixture is then transferred to a brick moulding machine. 2.
