On the Hydrobelt separator, contaminated sand is washed and freed of components of lower specific weight (e.g. wood, coal or other contaminants).
Moreover, this process enables a specified separation of fine sand for producing sand conforming to standards. In addition, the Hydrobelt separator ASE is equipped with a dewatering device which dewaters the sand product to obtain a conveyable product.

Design and operation

Also in these types of the GFT-Aquamator, the washing process takes place in a wash and separating bed formed by an endless belt of transverse stability with built-up vulcanised corrugated edges at both sides. The trough-shaped cross section can be varied according to task by means of adjustable idlers. Against the direction of movement of the belt conveyor, the sand-water mixture is fed into the washing/separating bed via a flushing chute.

Sizing and sorting with one machine
The sizing effect is based on the selective effect of sedimentation. Due to its high settling velocity, the coarse fraction moves downwards on the belt and is discharged continuously from the separating zone against the direction of flow. Water which is liberated floss back into the washing bed at a lower level. Product is discharged over the variable speed drive drum equipped with a belt plough. The fines still dispersed in the liquid, owing to the low settling velocity, flow against the direction of the belt conveyor over the tension drum into the tub located below. The Hydrobelt separator is pivoted at the product discharge side. An electric fast-vertical adjustment enables a variable adjustment according to the different feed materials in order to obtain quality sand. Depending on the respective adjustment of flow velocity, the residence time of the individual particle in the suspension can be varied and the cut point can thus be changed. Simultaneously, the sizing process is superimposed by a dense-medium separation, in which the sand content as well as fines content act as medium solids. Components of lower specific weight suspended or floating in the suspension, are also discharged together with the wash water.

Special features of Type AS
•	Shorter axial distance, flatter discharge angle
•	Additional water flush pipe with flat-profile spray nozzles for effective washing out sand still adhering on the corrugated belt edges
•	The product sand is dewatered to an optimum content on a downline screen
•	A fine sand recovery is recommended, to prevent slotted-hole screen losses

Special features of Type ASE
•	Longer axial distance, more acute discharge angle
•	Vibration plate located underneath the ascending conveyor belt compresses the sand
•	A downline heavy compression roll compacts the sand cake

Drive rating (kw): 3 - 4 
Dimensions length (mm): 5050

Year of construction: 1991:

The type AK Auqamator (DBP, German Patent) enables an efficient, cost-effective washing out of contaminants of lower specific weight from mineral granulates such as gravel, chippings, demolition rubble.

Construction and operation
The washing process takes place in a wash and separating bed formed by an endless belt of transverse stability with built-up vulcanised corrugated edges at both sides. The trough-shaped cross section can be varied according to task by means of adjustable idlers. The belt is led over a drive drum and a lower take up idler and runs against the upward slope. A rapper pulley located in the bottom part of the washing bed generates the pulsation there.
The contaminated sand fraction, with water already added, is fed via an adjustable feed chute into the separating and washing bed zone; feed direction is opposed to the direction of belt movement. Individually controlled, vertically and laterally adjustable spray pipes are located beneath the feed chute and also above the washing bed; these are equipped with flat- and round profile spray nozzles.

Due to the wash water flowing off in the direction of the tension drum which is situated at a lower level, favoured by the strong water spray of the nozzles and the frictional force on the belt in the opposite direction, a density separation occurs in the washing bed. The water pressure should be at least 3 bar. The pulsation zone at the end of the washing bed causes heavy contaminations already settled to be entrained by the flowing wash water and are thus better able to be discharged. After the cleaned sand fraction has been discharged over the elevated, infinitely variable drive drum, a re-dewatering is recommended. The wash water can be recycled after foreign material has been screened off.

Technical features Type AK

•	Low speed, no noise emission, low dynamic forces
•	Belt plough with water flush pipe
•	Feed chute, discharge chute and underflow trough with wear-resistant rubber coating
•	Minimum wear even for aggressive feed material
•	Special version: 200 mm corrugated edge height
•	Galvanised version
