The plasticity expressing in China’s brick and tile industry is now proposed by the Swedish A. Aterberg in 1911.Plasticity index is expressed as the range of water content when the clay is in a plastic state,whose value is equal to the difference between flow limit and plastic limit.Flow limit, also known as liquid limit, is water amount that clay enters a flowing state.Plastic limit is water amount that clay can be rolled into 3mm diameter.

Some brick factories are not equipped with rollers and mixers, even without the feeders, all by artificially feeding into the brick machine with shovel, which inevitably occurs two major drawbacks.

1, raw material soil cannot be stirred and mixed well. The plasticity of raw soil is not exactly the same, and sometimes the disparity is very great, the Yellow River sludge is like that.

2, the inside fuels such as coal, coal gangue, slime and others cannot be stirred evenly. The two heterogeneous, will inevitably lead to the instability of adobes’ quality.
