The 12 volt system is slower than the gas powered unite by about 1/3rd volume less. The gas powered machine should max out around 1 yard per hour and the 12volt DC around 2 3rds of a yard. Simply more water more material. I would estimate a standard automotive battery Group 24 size should last 6 hours of so more than my old back can handle.

The machine, shown in Figure 1, operates like a large ball mill with a screen built into the side. Each revolution of the large drum results in an impact stroke and a screening stroke. As seen in Figure 2, the low RPM corning drum contains a single lift bar and a half dozen or so grinding balls such as billiard balls or something similar in

The larger the orifice ID opening the larger volume of air/media. Other factors that affect volume of air into the blast system is media and air hose diameter. Increased air pressure (PSI) also increases the SCFM with a given size orifice. . Industrial blasting gun bodies of suction cabinet blast systems range between 12 to 38 SCFM.

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.

Ball mills with two different sizes were considered in this study, one small and another large. The simulations with the two mills have the same conditions as the real ones by Valderrama et al. (1996) and Kalala and Moys (2004), respectively, in terms of mill size, particle size, mill speed fraction (mill speed as a fraction of critical speed) and fill level fraction.

The ball charge occupies approximately 1/3 of the capacity of the mill. A single 250 horsepower, 1170 rpm, 4160V, three phase, 60HZ electric motor drives the ball mill. The mill rotates at 20.8 rpm and a variable voltage controller allows the unit to step up to operating speed. The unit is considered a single speed mill.

IF you are attentive to the lubrication Babbit works fine. Pillow blocks may be self aligning, and will work at higher speeds, but if you aren''t speeding the thing up, the only ''benefit'' is reduced attention need to lubrication. Babbit bearings aren''t very happy if you run them dry. 11-27-2009, 09:56 PM #3. JZC.

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables ‘the old fashion way’.

Pump sizing involves matching the flow and pressure rating of a pump with the flowrate and pressure required for the process. The mass flowrate of the system is established on the process flow diagram by the mass balance. Achiev-ing this mass flowrate requires a pump that can generate a pressure high enough to overcome the hydraulic resistance

CHARGE VOLUME OF A GRINDING MILL- Volume of the charge – volume of material within the liners. It contains both the feed and the grinding media. It is calculated when the mill is at rest. Average volume is calculated. Weight of the charge is calculated with its bulk density. Ball Mills are normally run with charge volume < 45 %.
