Gypsum and plaster line

At Domenech we offer advanced solutions for different productions of material quality that is fully controlled in its process. All facilities offer “turnkey” execution, from their conception at the engineering level to the launch of the manufactured product.

Scroll through the image and you’ll find the names of the different phases.

01

The input material (with a size of up to 300 mm, from a crusher) is placed in a hopper where it falls to a primary schredder in charge of making a first trituration. The material is reduced to a granulometry of approximately 0-45 mm. Next, a conveyor belt takes it to a bucket elevator, which will store the mineral in a silo.

02

In this second phase, the material is transported by a conveyor belt from the storage silo to a vibrating screen, where the mineral with a lower granulometry falls directly to an screw conveyor and the larger one passes to a schredder, leaving it with a granulometry from 0 to 3mm, which will then go to the same feeder mentioned above. This feeder carries the material to a bucket elevator.

03

The burn-out phase begins with the measurement of the mineral that passes from the bucket elevator to the weighing hopper, where the amount of material that will enter the furnace is weighed. Once weighed, a linear feeder transports the material to an screw conveyor that will progressively introduce it into the furnace, which will dehydrate the mineral at a temperature of approximately 180 degrees (depending on the product to be obtained).

04

Parallel to the post-burn-out process, the suspended elements are filtered with a sleeve filter.

05

Once the material is dehydrated, it goes to a hopper where it accumulates and passes from an alveolar feeder to an screw conveyor that leads to a bucket elevator.

06

The last phase begins with the bucket elevator that leaves the material in a particle separator, where the particles with the required granulometry pass to a fluidized trough and the larger ones fall into a bar schredder where they are crushed. The ore and returns it to the bucket elevator that will pass the product again through the particle separator. The fluidized chute transports the plaster to another bucket elevator. This last bucket elevator fills the storage silo.

07

The silo measures the material, which can be served, either in bulk (trucks or big bags), or by feeding a bagging machine.
