    摘要： An electric motor operated rotary drum type grinding mill is operated at optimal efficiency by detecting and analyzing the motor current. The power signals are converted by signal processing equipment for presentation as pictorial display representations of mill operating conditions at a variety of motor current levels to permit unskilled operators to understand the current operating conditions. Instantaneous on line current signals are derived from the mill by a transformer coupling without rewiring or modification. Analytical equipment processes the detected current signals for mill control, storage of historical performance and pictorial display. Mill operation is accordingly controlled in semi-automatic or fully automatic modes that maintain optimum mill efficiency.

    摘要： Concretes containing Portland cement, fly ash and aggregate are disclosed which are capable of attaining high compressive strength and which contain relatively low proportions of Portland cement and relatively high proportions of a select fly ash component. The inventive concretes may be formulated as highly dense masses particularly suited for use in the manner of conventional structural concretes in buildings, bridges, dams, etc. Comparatively low density concrete masses may also be produced which are light in weight and have thermal insulation value rendering them particularly suited for use as thermal insulating components of roofs and as protective coatings for a variety of substrates.

    摘要： Concretes containing a hydratable cementitious binder such as Portland cement and a high strength aggregate material are described. The high strength aggregate material is produced from hydrated cementitious compositions which contain relatively low proportions of Portland cement and relatively high proportions of a select fly ash component. The high strength aggregate material is produced by mixing the aforementioned Portland cement and fly ash components with water and allowing such to hydrate. The hydrated aggregate product may then be reduced in size (e.g. by crushing) and screened prior to combination with the cementitious binder to produce concrete compositions. Concretes can be prepared with such aggregate which have at least comparable compressive strengths to concrete prepared using conventional crushed stone aggregate.
