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

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.

Wilfley Table Installation Instructions

Important Precautions

A. The unit is packed with plastic securing ties holding the table deck shaft, onto its support half bearings, and also securing the gearbox cover and ancillary yellow piping. These must be removed before use.
B. THERE IS A SMALL WOODEN BLOCK INSERTED BETWEEN THE DRIVE THRUST YOKE (PART 133) AND THE GEARBOX CASING. This is to prevent movement of internal parts during transport and MUST be removed prior to electrical connection and start-up (see photo)

Wilfley Table 2

C. Raise the water manifold support after removal from timber crate and securely bolt in upright position.
D. Ensure the head motion is filled with SAE 20W/50 oil (Automotive grade) to the correct level as shown in the maintenance section of this manual before running.
E. Adjustable “feet” mountings (FOUR off) are pre-fitted to the base legs. These will require adjustment to level the machine in its location prior to operation.

Wilfley Table 3


The machine is mobile for use, with adjustable feet for levelling prior to operation. Position on a flat level surface ideally at a level suitable for the operator to observe separation and provide sufficient room for the operator to walk around the machine.


Water Supply

Connect the water pipe nozzle to a clear water supply using flexible rubber hose.
Typical wash water requirement is 5 – 10 litres/minute.
Recommended feed dilution water is 3 parts water to 1 part solid. i.e. 25% Solids w/w
A spray gun and hose are provided to assist with washing off the decks, launders and washing products out of the buckets.

Electrical Connection – Power Up

The AC Inverter Unit should be connected to a 230 Volt or 110 volt Single Phase (dependant on customer selection and clearly marked on the inverter), protected electrical supply.


Connect the single phase mains supply (refer to technical specification for voltage requirements) to the terminals marked “L” and “N”, the earth wire must be connected to the Earth terminal marked “E” (or the earth stud on the heatsink).

Operating Instructions

Choosing and Changing Decks

The standard unit comes complete with Sand (Parallel Riffle Pattern for Coarser particle/easier separations) and Fine Sand decks. (Angled Riffle pattern for Finer/More difficult separations)

Installing a deck is easy. Simply lower the deck onto the half bearings gently and connect up the deck support shaft to the head motion by tightening the M16 nut with a 24mm spanner. Connect up the water supply to the wash water pipe.

The decks are changed by simply releasing the locking nut on the deck support shaft using the Tommy bar provided, uncoupling the wash water pipe and removing the deck.

Preparing for Operation

Turn on the wash water and ensure that the water is running evenly over the deck and is free of any dry patches. Start the machine and run for a few minutes on water only to wet all table edges.

Prepare the table feed by mixing the dry solids with water to give a 25% solids by weight mixture. Some feed stocks are “Non – wetting” and will require addition of a wetting agent to assist settling of these particles which would otherwise float to tailings without having been influenced by their gravitational forces.

Place all sample buckets under the product off takes.

The feed material will also respond better on the table if the feed has been sized beforehand so that all particles are in a narrow size particle band. This avoids coarse “lights” reporting with fine “heavies” (Stokes Law) and therefore gives better separating performance. The degree of sizing will be specific to the material and should be determined by experimentation.

Operational Parameters.

Feed rate

Feed rate is a function of particle size and specific density differences between particles. This can vary from a few kgs/hour upwards. However, as a general rule, the finer and/or more close density the separation between particles the lower the feed rate will be. (Typical max. 70 kg/hour)


Table Tilt

The angle of tilt is adjusted by slackening the M16 nut at the drive connection (24mm Spanner). This will release the deck and it can be adjusted to the angle required.

The correct slope can only be determined by visual inspection of separation. However, as a general rule, the greater the slope the cleaner the concentrate grade and lower the recovery and vice versa.

The angle of the table from feed to concentrate end can be adjusted using the hand wheel located under the support beam at the concentrate end of the table. This angle can only be optimised by trial and error. However, the higher the concentrate end the longer the material remains on the table.

Wash Water

The wash water should flow evenly over the deck. The quantity of wash water can only be determined by experimentation. Higher wash water volume results in cleaner concentrates and lower recovery and vice versa.

Stroke Length

The stroke length can be adjusted by the Stroke Adjusting Screw (Part No 163) located under the lid at the front end of the Head Motion.

Lowering the stroke adjusting block increases the stroke length.

Coarse Particles require a longer stroke length than finer particles.

Stroke Speed, rpm

Turning the AC Inversion box control dial varies the stroke Speed.

We have set the mid-point (setting 50) to maximum setting on the inverter to coincide with the most useful range of speeds i.e. 200 – 300 rpm. The instruction leaflet for the AC Inverter is in the control box.

See Section 2.8 for Stroke Speed versus dial settings.

Product Cutters

Two cutters are provided (for customers with launders only) to assist with guiding products into the appropriate launder off takes.





How to Maintain a Wilfley Shaker Table

Head Motion

Maintain the oil level so that the eccentric shaft is just immersed in oil and is able to lubricate the upper parts by splashing. (approximately 0.5 litre)

At Monthly intervals and/or after a longer period of non use, remove the head motion lid and apply a small quantity of oil to the exposed working parts.

The Head motion oil (SAE 20W/50) level should be visually checked by removing the head motion lid and topping up as necessary.


If the machine is in constant or daily frequent use, change the oil after 1 month of operation from new and every 6 months subsequently.

Table Deck Half Bearings

The Table Deck assembly rests in two Half Bearings which are self – lubricating. (Do not grease)

Table Decks

The Deck should be thoroughly wetted before use and washed down after use.

Any grease spots may be removed with a detergent.

TWO decks are supplied as standard.
One deck for fine sand samples (particle size ~<250 microns) [This deck has angled ends to alternate riffles]

One deck for coarse sand (particle size ~>250 microns, up to ~1000 microns). [This deck has ALL parallel riffles]

When changing decks it is necessary to refit the deck FEED BOX, and DECK THRUST SHAFT.
