The biggest benefit of Flexible shaft grinder is its possibility to operate in restricted areas at constant speed. Thus Rajlaxmi make Flexible shaft grinding is the most appropriate method to grind or polish heavy unmovable or heavy to handle jobs there by giving freedom to the operator to grind the job without handling it. RAJLAXMI make Flexible Shaft Grinders manufactured at Rolex Enterprise Rajkot, Gujarat, INDIA. These grinders are continuous duty rating, easy to operate, robust constructed, vibration free and low maintenance as a result of which high productivity is achieved at lowest consumption of power

The earliest grades of microcrystalline grits were produced as early as 1963 (Ueltz, 1963) by compacting a fine-grain bauxite slurry, granulating to the desired grit size, and sintering at 1500C (2735F). The grain shape and aspect ratio could be controlled by extruding the slurry

Foam fractionation, also called protein skimming, air stripping and froth flotation, removes surface active (surfactants) dissolved organics and suspended solids, which may be produced in the culture system. If aeration is vigorous, the process can also drive ammonia and volatile components directly to the atmosphere. Additional benefits include the removal of fine particulates and excellent aeration. The process can be very efficient but in some applications has been disappointing. It can be very sensitive to small design details and choices in values of operating variables. The process is believed to be most effective in marine applications, especially in lightly loaded systems. Most seawater applications have been aquarium reuse systems. If it is to be combined with ozonation, some users have strongly recommended, for system control reasons, to separate the two processes by not using ozone in the foam fractionator's gas supply but applying it separately. The equipment, unlike biofilters, does not require much space and maintenance is usually minimal. It is sometimes used in combination with biofilters instead of as a substitute

Better automation and control systems for mining equipment could also lead to large gains in productivity. Some equipment manufacturers are already incorporating human-assisted control systems in newer equipment, and improvements in man-machine interfaces are being made. Additional research should focus on alternatives, however, such as more autonomous vehicles that have both sensor capability and sufficient processing power to accomplish fairly complex tasks without human intervention. Tasks include haulage and mining in areas that are too dangerous for human miners. Semiautonomous control methods should also be explored, such as fly-by-wire systems in which the operators actions do not directly control the vehicle but give directions to a computer, which then decides how to accomplish the action. A good example of this technology is currently being used in large construction cranes; the motion of the crane to move a load from one location to another is controlled by the operator through a computer, which controls the rate of movement of the crane in such a way as to minimize the swing of the load. This technology has considerably improved safety, speeded up cycle time, and enhanced energy conservation in the motion of the crane

Roll crushers are also manufactured with only one rotating cylinder (Figure 6.14(b)), which revolves toward a fixed plate. Other roll crushers use three, four, or six cylinders, although machines with more than two rolls are rare today. In some crushers the diameters and speeds of the rolls may differ. The rolls may be gear driven, but this limits the distance adjustment between the rolls. Modern rolls are driven by V-belts from separate motors

Grinding principle of vertical roller mill is the use of 2 ~ 4 rollers to the disc, as the speed of rotation the ground material, basically belongs to the material layer grinding The material is mainly due to the rolling action of grinding roller and grinding in the mill, the grinding roller and disc rotation speed difference between, so has the shear milling Effect of feeding disc center

Microbial electrolysis batch reactor systems were studied employing different conditions, paying attention on the effect that biocathode potential has on pH and system performance, with the overall aim to distinguish sulphate reduction from H 2 evolution. Inocula from pure strains (Desulfovibrio paquesii and Desulfobacter halotolerans) were compared to a natural source conditioned inoculum. The natural inoculum possess the potential for sulphate reduction on serum bottles experiments due to the activity of mutualistic bacteria (Sedimentibacter sp. and Bacteroides sp.) that assist sulphate-reducing bacterial cells (Desulfovibrio sp.) present in the consortium. Electrochemical batch reactors were monitored at two different potentials (graphite-bar cathodes poised at -900 and -400mV versus standard hydrogen electrode) in an attempt to isolate bioelectrochemical sulphate reduction from hydrogen evolution. At -900mV all inocula were able to reduce sulphate with the consortium demonstrating superior performance (SO 4 2- consumption: 25.71gm -2 day -1 ), despite the high alkalinisation of the media. At -400mV only the pure Desulfobacter halotolerans inoculated system was able to reduce sulphate (SO 4 2- consumption: 17.47gm -2 day -1 ) and, in this potential condition, pH elevation was less for all systems, confirming direct (or at least preferential) bioelectrochemical reduction of sulphate over H 2 production.
