Ultra High Frequency Shaker Tables Gets All Your Gold! Model Description Water (GPM) Tons/Hr 4080 4'x8' Roughing Table 20 2 Table Riffles Table: Straight UHMW - Riffles are machined into a UHMW plastic top at 1/8" Depth. This riffle configuration is used where a large amount of concentrate is generated. Power Table is standard with a variable speed motor wired for 110, 60 cycle. Feed Included is a manual feed vibratory feeder with hopper we built for loading material onto the Roughing Table. Maintaining a steady rate of feed is critical for maximum extraction. The Ultra High Frequency Advantage You work very hard digging your ore. Why loose any portion of it to an inferior concentration process? The UHF difference and how it improves on typical Shaker Tables 1.) The action of the table is not provided by a mechanical motion, but by high frequency vibration. This allows a much higher frequency than that obtainable by mechanical means. A typical frequency for a Wilfrey style table is 250 strokes per minute. The UHF concentrator is making up to 1,750 or 7 times the number of impulses per minute. This faster speed allows for a more efficient and rapid stratification of the bed of minerals. The sooner a denser particle comes into contact with the table surface, the sooner it is moved by the table action toward the concentrate end, and the less chance there is for it to be carried away with the tailings. 2.) Because the motion is provided by a vibrator instead of a mechanical motion, the direction of the motion relative to the table can be changed. Typically it is set somewhere in between straight down the table (as in the Wilfrey design), which gives greatest capacity at the expense of lesser separation, and 90 degrees off that setting, which gives minimum capacity, but best separation. By setting the direction of vibration up from straight down the table, gold and other heavy particles can be made to move up the incline of the table against the current of water as they proceed toward the concentrate end. In many cases this allows for the generation of a gold concentrate so pure that it can be directly melted. 3.) The UHF table is designed to give the operator total control of the table action. In addition to the adjustments available on other tables, the vibrator speed, direction, and force, and table balance can be changed. These additional controls can be the difference between being able to treat an ore by gravity means, and having to resort to more expensive chemical methods. 4.) The UHF table uses specially designed riffles which are back cut to provide a low pressure area of safety for fine mineral particles. This is simply the application of the principles of riffle design that have been demonstrated as being effective in modern sluice boxes. Strangely, most tables still use a straight cut riffle. The riffles on the UHF table occur in a deliberately irregular pattern, as well as having areas of the table between them that are free of riffles. This prevents the occurrence of standing waves on the table that can carry mineral particles down the table. This is similar to the reason that band saw blades have an intermittent pattern of teeth. If they were equally spaced, a harmonic vibration could result, damaging the material, the blade, or both. Riffles on the UHF table can be tapered or non-tapered. Typically a tapered riffle is preferred, as it tends to give a cleaner product, but a non-tapered riffle will increase capacity where a large amount of concentrate is created, and is recommended for roughing tables. While we encourage local pick up, if Buyer is unable to pick up, we will build a pallet and prepair the table for transport (Cost $200). We will also assist Buyers in arranging delivery via Freight at Buyers' expense. If you have any questions simply send an email with your phone number and we'll get right back to you.
