煤矸石掺配适量塑性高的物料。
Coal gangue is mixed with a proper amount of high plasticity material.
有条件的话，掺配适量塑性高的物料，比如淤泥、页岩、黏土等，是简单、经济、有效提高物料塑性的措施。对多种物料掺配混合使用，一是要掺配比例合理恰当，计量准确；二是要保证各种物料混合均匀，特别是密度差别较大的多种物料，除使用搅拌机等常用设备外，还应使用轮碾机、圆盘筛式挤料机等强制混合揑练设备。
If conditions permit, it is a simple, economic and effective measure to improve the plasticity of materials by mixing appropriate amount of materials with high plasticity, such as silt, shale, clay, etc. For the mixing and use of various materials, first, the mixing proportion shall be reasonable and appropriate, and the measurement shall be accurate; second, it is necessary to ensure that all materials are evenly mixed, especially for the materials with large density difference. In addition to the commonly used equipment such as mixer, the forced mixing equipment such as wheel mill, disc screen extruder shall be used.
