After determining production scale, it is possible to determine area, process direction, equipment layout of production plant and the location of living area according to the size of production volume.Plan plant elevation based on local geological, hydrological and meteorological conditions.]Arrange various production workshops according to the wind direction.To determine the mode of production, shall it be labor-intensive companies or technology-intensive enterprises,requires whole careful plan and design by technicians based on the results of technical and economic analysis.

According to this method, the plasticity index is used to classify clay as: high plasticity clay >15%; medium plasticity clay 7%-15%; low plasticity clay<7%.

This method has been widely used for many years in the fields of soil science and engineering geology.Although China's brick and tile industry has been using it for many years, it is only for soft and dispersed clay raw materials.For coal gangue, shale, etc., which rely on reducing particle size to obtain plasticity, there is a great deal of deviation in using this method.For example, the plasticity of raw materials such as coal gangue and shale depends on crushing to reduce the particle size to a certain degree, adding water to the particles after decomposing (aging), and it is changeable during processing.If the hard clayey shale or coal gangue rich in illite is ground to a sufficiently fine degree (such as cement fineness),the plasticity index may reach a pretty high level.And formed moisture content and drying shrinkage may be larger than common clay materials, which totally differ from common brick clay.
