Product Description

Work Flow of Autoclaved Sand-Lime Bricks Production Line

1). Raw materials Storage and Mixture Preparation

1.1 Quick Lime
After transported to the factory, the massive lime will be poured into the receiving hopper by the forklift. It will be smashed by the jaw crusher before delivered into the silo by the bucket elevator. In the silo, the lime will be fed into the milling equipment for fine grinding. Then, you can use the lime powder to make the cementing materials. Later, the bucket elevator will convey the cementing materials to the cement silo.
1.2 Coal Ash
The bucket elevator will put the wet coal ash onto the batching scale for measuring.
1.3 Sand
Sand will be transported to the factory, and piled in the designated area. It will be then conveyed into the batching machine by the bucket elevator.

2). Batching and Mixing

The above materials after measured, will be discharged into the mixer in order. Prior to the initial mixing, you need to add water. The mixed material will be sent into the continuous slaking silo. And then, it will be mixed once again in the edge mill or mixer. If necessary, you can add some water when mixing. Finally, the belt conveyor will convey the mixtures to the hopper of the brick molding machine.

3). Green Brick Forming

The mixtures inside the hopper of the block molding machine will be fed to the mould, and the green bricked is formed. On average, the molding cycle will be 13 to 17 seconds. Via the articulated robot, belt pulley, and automatic stacker crane, the green brick will be piled onto the autoclave trolley.

4). Curing and Storage

The autoclave trolley on which green bricks are stacked, will be sent to the autoclave for curing by the dragger. When the curing is over, the dragger will pull the autoclave trolley

together with the bricks out of the curing system. The finished bricks will be unloaded from the trolley. Meanwhile, they will be inspected, and stacked after classified.
