·The naturally structured clays are Osaka clay [1] and Marl clay [2] and the artificially structured clays are cemented Araike clay [17] [20] and cemented Bangkok clay [58] The simulated shear behaviour of the same clay in both destructured and structured states using the same destructured model parameters is illustrated by the test results
The RollSizer are capable of crushing medium hard rock as well as sticky and soft material such as coal clay marl limestone and similar raw materials The material is crushed by shear and tensile forces generated by high rotor torques at a low circumferential speed
·Lightweight expanded clay aggregate LECA is a lightweight granular material which can be used as an ideal backfilling geomaterial attributed to its porous particles Through X ray tomography images it is found that LECA particle is a porous composite particle with a strong shell and a fragile core originating from the sintering
·Mixed crushing refers to the production process in which two raw materials in cement production are sent to a crusher at a certain ratio for crushing Common mixed crushing includes limestone and marl limestone and shale limestone and clay etc ; sieving the raw materials before crushing only crushing the sieve can often achieve good results
·Surface materials are extracted through an opening or excavation called a pit The most common is aggregate which is made up of sand and gravel Some pits also produce marl or clay A pit site may include roads; facilities; stockpiles; processing activities such as crushing screening and washing
·The clay minerals in the study area consist mainly of detrital smectite I/S and illite and authigenic talc and Mg smectite that transformed from sepiolite in which Mg originated from high Mg 2 parent calcites and Si was due to seawater mixing with <∼5% terrigenous and <∼% hydrothermal contributions Compared with limestone beds
5 ·The most important raw materials for making cement are limestone clay and marl These are extracted from quarries by blasting or by ripping using heavy machinery Wheel loaders and dumper trucks transport the raw material to the crushing installations There the rock is broken down to roughly the size used in road metalling Raw material
