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.

A 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.

Packed 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.

The 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.

2009-11-19The performance of the castable material as a refractory is ultimately determined by whether the construction on the spot and the drying state are good or bad. 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.

6. Chains on these applications should be adequately lubricated and properly maintained at all times. 7. Chain reliability is based upon a good press fit of the pins and bushings into the sidebars. Therefore, do not grind the chain pins, bushings, or holes in the sidebars in order to assemble the chain as supplied from the factory. 8.
