An experiment designed to simulate coal during excavation was conducted. Microseismic signals of coal under vibration conditions during excavation and subsequent waiting time of the coal roadway at different excavation speeds were collected and analyzed. During the excavation and subsequent waiting time, the stress in coal is redistributed, and the concentrated stress is gradually transferred.

In the DR industry, a number of facilities briquette their hot DRI product to produce a higher-density product for safer shipping.
Live ChatA refractory brick which has durability equal to that of alumina-magnesia casting materials and is suitable for use especially as a ladle for steelmaking. For producing the refractory brick, a raw alumina material and a raw magnesia material at least 90 mass of which is accounted for by fine particles of 0.5 mm or smaller are used. The brick has a total content of Al2O3 and MgO of 90 mass or.
Live ChatPacked column chromatography provides a good resolution of the PSD for particles with diameter smaller than 250 nm. Capillary chromatography is capable of providing consistent results for routine quality analysis in a wide size range. The potential of the above techniques for on-line applications and control purposes is discussed.

Live ChatThe technical scale briquettes are produced using vibro-press machine and the mechanical strength has been evaluated based on the drop test and tumbler index measurement. The impact of the developed briquettes on energy saving and CO2 emission will be discussed based on heat and mass balance mathematical model.

The kneaded material can be molded by a vibration press or a molding machine called CIP in addition to a friction press which is an impact press, a screw press or a hydro-screw press.
