Since 1942 Strommasina Corp. has been successfully producing equipment for the mining, building, oil and gas, as well as road, metallurgical industries.

Ceramic brick production equipment

There are several ceramic brick production methods, but clay is the raw material for bricks anyway. There are several methods of brick production, and they are varying with fairly fast pace of up-to-date technologies. Identical equipment can not be installed in all plants as the source material (clay) can be can be very much different in different regions. But anyway, the source material shall be homogeneous. Excessive limestone content is the main adverse factor for clay in this case.

The primary clay raw material processing is performed using different equipment. Grinding, clay crushing is performed in clay crusher. The clay crusher is designed for pre-processing of argillous raw material with ultimate compression strength up to 40 kg/cm and humidity no more than 30%. The clay crusher consists of a crushing assembly designed as two blade counter-rotating shafts (blades of one shaft moving through notches between other shaft's notches), a rigid frame, a receiving bin and a gear drive.  When the blade shafts rotate, clay lumps passing between the blades and ribs on the frame are crushed.

Method of plastic moulding of ceramic bricks

It is the most popular ceramic brick production method. The optimal raw material for this method is clay containing up to 30% of sand which prevents from an excessive brink shrinkage. After producing properly composed clay it is moistened with steam and subjected to thorough mixing  until homogeneous tabular mass is produced without any pellets. To obtain homogeneous mass, a crusher homogenizer is used. It mixes, grinds and additionally moistens the mixture. Then this mass is used to form raw bricks, and taking into consideration subsequent shrinkage, the volume of raw bricks is greater (by 10 to 15% approximately). Once raw bricks are formed, they are dried and when 6 to 8% moisture content is achieved, they can be burnt in the kiln at 1000 *С (some additives may be used to accelerate burning process).

Dry and semi-dry pressing method

Although the bricks produced using such method are less frost-resistant, they are more suitable for producing producing products with sharper shape. However, the raw material (clay) with somewhat different moisture content is selected (stiff clay with 7 to 8% moisture content and 8 to 12% moisture content for semi-dry pressing), and as distinct from plastic moulding, clay is ground to powder in this case. Then the powder is moulded in presses without any drying at all (in case of dry method), or with significantly reduced drying time (in case of semi-dry method), and raw bricks are ready for burning.

Additional brick production equipment

In addition to basic grinding and pyroprocessing equipment, some additional equipment types are used in brick production, for example, screening and conveying equipment. Specialised crushers are installed for processing crushed bricks. For example, hammer crusher SMD 147 А can be purchased for this purpose. The Samara Strommashina plant manufactures and supplies such equipment and provides all necessary technical support.
