After the selected brick raw materials are processed, they enter the molding workshop for molding.Blank forming method basically uses plastic extrusion molding in China.There are three methods for plastic extrusion. That is plastic extrusion molding,semi-hard plastic extrusion molding and hard plastic extrusion molding.

For example, assuming that the type and total amount of clay minerals contained in a kind of clay are exactly the same as that in a certain type of shale, plasticity index measured by the geotechnical test method is much higher than shale,because  dispersed clay mineral particles in the clay are uniform and small.If the shale is fully crushed, so that the clay minerals in the shale reach a finely dispersed state like the clay mineral particles contained in the clay, it is possible that the plasticity index measured by the geotechnical test method will be the same as that of the clay.However, it can’t be achieved in actual production,causing a great plasticity fluctuation during processing raw materials such as coal gangue and shale.Which method should be used to describe and compare the plasticity of these raw materials?

1, Malformed adobe, appears large cracks. In more serious cases, the whole adobe will split.

Reasons: the plasticity index of pug is too low, almost no plasticity.

Solution: to increase the plasticity index of raw materials, such as clay, coal slime or clay agent, etc.

For raw materials of low plasticity index, it can also be improved after aging, watering, stirring, rolling, extruding and other methods.
