The technology of brick making

Clay prepared for the manufacture of bricks in Keramat JSC

The bricks are offered in euro pallets or as loos according to the customers' preferences. The products of Keramat JSC - the town of Kaspichan - meet the requirements of the European Union (EU) and BNS and are accompanied by certificates for quality.

Bernini Burners

The company has its own transport and a large fleet with different logistics units.

The marl clay is a basic material for producing ceramic blocks for building; the clay is extracted from a clay-pit, situated on the territory of the factory. The clay is kept in a special room where it is being watered in order to raise its humidity up to 16%.

From the temporary warehouse the clay is passed together with some slack (middling slime). The needed quantity of clay and middling slime is dosed with the help of sliding rules and then the substances are mixed. The mixture is passed on a conveyor belt to a kollergang for wet grinding. The purpose of the kollergang is to shatter, dispergate the clay and to mix it in advance with the other components of the raw material. The material passed is mixed and irrigated with water in order to get more humid.

Production of bricks

The clay mixture produced goes to the conveyor belt which takes it to smooth and rough cylinders. From there on a rubber conveyor belt the roughly ground material is proceeded to smooth-precision cylinders. From there through a conveyor belt and a lamellate transporter the material is carried to an indoor clay warehouse. 

There the material stays less than 72 hours. The ground material gets evenly humid and acquires good moulding qualities. From the indoor clay warehouse the clay is transported to the mixer machine of the vacuum press where the clay is irrigated, humidified and mixed with raw material; after that the clay is passed into a vacuum - a vacuum chamber - press.
