Mar 01, 2008 For superabrasive wheels, a flow rate close to 1 gpmhp 3.8 Lminhp works well. This flow rate must be applied directly into the grinding zone, with additional flow rate for cleaning and flushing nozzles. The machine controller may be used to determine the approximate grinding power, or a phase-corrected power meter can be used.
Jul 24, 2013 An example of how you can calculate the slurry flowvolume of a given SG, Solids and Tonnage. EXAMPLE 3,400 tons of dry solids is processed in 24 hours in water with a specific gravity of 1.0 and the. concentration of solids by weight is 33 with the solids having a specific gravity of 3.7 then using the formula below
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm about 30 to 35 msec. High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
11.14.5.2 Material Removal Rate. The material removal rate is defined as the amount of material removed from the workpiece per unit time. The material removal rate can be calculated from the volume of material removal or from the weight difference before and after machining. It is an indication of how fast or slow the machining rate is and an ...
