The Wilfley Shaker Tables are gravity concentrating devices that separate material based upon differing densities of the material. They are effective in concentrating high density minerals, such as precious metals, have been used in metallurgical applications, mineral processing applications, soil remediation and recovering light density ores, such as coal from the heavy density refuse.


The Wilfley Tables have two distinct deck designs available. The sand deck is designed for recovering particles sized from 20 mesh to 200 mesh. The slime deck is designed for recovering fine particles in the range of 200 mesh to 325 mesh. The model 13-A is the laboratory sized Wilfley Table and is ideally suited for lab or pilot plant test work.

Utilizing the sand deck, a Wilfley Table can concentrate ore in the 20 mesh to +200 mesh particle size range. With the slime deck, it will concentrate ore in the 100 mesh to +325 mesh particle size range. The capacity for a lab size Wilfley Table (13A) is between 30 and 50 pounds of feed per hour, with lower capacities when using the slimes deck.wilfley laboratory shaker table


  • Feed and Water Box is of Fiberglass construction with hose (discharge), hopper (feed).
  • Constant speed v-belt motor drive.
  • Furnished as either right or left hand tables.
  • Fiberglass launders included with table.
  • Sand deck is standard, a slimes deck is optionally available for the –100 mesh to +325 mesh ore.
  • The stroke is adjusted by raising one end of the toggle with an adjusting screw, a variance in stroke length from 0.75” to 1.25” can be obtained.
  • Self locking tilting mechanism
  • Deck is supported on 4 bearings carried in rocker pockets which are a part of the tilting beams. The deck may be inclined from horizontal to a slope of 1 inch per foot.
  • Self-Lubricating head motion
  • TWO gel coat, decks (fine and coarse sample processing).
  • Five outlet launder with two splitters for adjusting output.
  • Water manifold with spray gun, feed dilution, and Wash water controls fitted.
  • Stroke, tilt and end slope easily adjusted, while Machine is operating.
  • Stroke frequency by inverter (customer power Feed direct connection to inverter, with options of 110V, 230V single phase) .
  • All framework stainless steel.
  • Adjustable feet for levelling base frame.
  • Machine is portable (no permanent bolting down required) for easy relocation to testing area.

The sand deck is efficient in separating high density from low density material (with a difference of 1 SG unit), in the particle size range ranging from 10 mesh to 150 mesh.
Slimes decks are used for particles in the 150 to 325 mesh range. However, as one that has used the slime deck, the surface tension of water interferes with recovery in this particle size range. This is probably why 90% of people using the tables use the sand deck.

The most popular of several similar devices, the Wilfley Shaking Table was developed in the 1890s. It has been in use since and is a common device for concentrating particles in the intermediate range, such as 10-200 mesh (1.65 mm-74 pm) particles for ore and 3-100 mesh (6.7 mm-150 pm) for coal. It is an oblong, shaken deck, typically 1.8- to 4.5-m wide; the deck is partially covered with riffles that taper from right to left. The deck is gently sloped downward in the transverse direction. Feed enters at the upper right and flows over the riffled area, which is continually washed from a water trough along the upper edge of the deck. Heavy particles are concentrated behind the riffles and are transported by a bumping action (of 12-25 mm throw at 200-300 strokes/min) to the left end of the table where flowing film concentration takes place.

Principles of Operation

Gaudin (1939) identified three principles of operation: hindered- settling, asymmetrical acceleration, and flowing film concentration. The hindered-settling action takes place in the boil behind the riffle. Asymmetrical acceleration, from a spring and from the bumping action supplied by a pitman and toggle arrangement (not unlike that in a Blake-type jaw crusher), not only transports the material behind the riffles but also helps to separate heavy from light materials. Heavy minerals are influenced less by the bumping action than are light ones, and thus the heavier particles have much longer residence times on the deck than do light ones. The bumping action also keeps particles in motion and allows the wash water to remove light particles more thoroughly. Final particle separation is made on the flowing film pan of the deck, which produces a superior heavy mineral concentrate.

The final slope sequence is fine-to-intermediate heavy panicles highest upslope, fine light and intermediate-to-coarse heavy panicles in between, and coarse light panicles furthest downslope. This sequence differs from that of a hindered-settling classifier. Accordingly, it is common practice to have separate shaking tables, each with different settings, treat the various spigot products from a hindered- settling (sorting) classifier.

Industrial Applications

Whether shaking tables or some other intermediate-to-fine gravity concentration devices are used for roughing, shaking tables are commonly used for cleaning to produce an acceptable concentrate. They are frequently used for upgrading heavy minerals that are not well floated, such as -Win. (6.4 mm) coal particles (as coarse as -10 mm in some instances), small middling streams, and heavy particles to be removed during environmental remediation. The latter is typified by such procedures as removing metal splatter from foundry sands and separating metal grindings from abrasives. In treating relatively coarse -8-mesh (2.4-mm) ore particles, the tables can handle several tons per hour, but for much finer, 150- to 400-mesh (100- to 37-pm) particles, and their capacity may drop to about 0.3 tph. If -10-mm coal is treated, a capacity of 12 tph per deck may be achieved. To clean coal, shaking tables are often stacked two or three decks high, all controlled by the same shaking mechanism.
