WASHING AND DEWATERING SYSTEMS

WASHING AND DEWATERING SYSTEMS

DEWATERING SCREENS

Dewatering screens separate sand and water in washing applications and ensure that the water in the product is filtered.

The dewatering screens are driven using vibration motors and the movements of the screens are linear. In this way, the material is forced to go in a reverse slope on the screen surface and it is separated from the water.

SCREW CLASSIFIER

Screw classifiers are the simplest and most economical solution to obtain washed sand. Screw classifiers, which have very low investment and operating costs, do not need much maintenance because of their simple mechanical structures. MADEN Makina produces screw classifiers in different diameters and lengths, with a capacity from 20 tons per hour to 200 tons per hour.

BUCKET SAND WASHERS

Bucket sand washers are also economical equipment frequently used in sand washing applications. Bucket sand washers with a low need for clean water are the ideal solution for washing operations where the fineness gradation of the washed sand is not very sensitive. Bucket sand washers, which are very easy and inexpensive to operate and maintain, are an important alternative in terms of equipment that can be used in sand washing operations.

HYDROCYCLONE

With traditional sand washing methods, small grains of sand are lost along with the water. This means a loss of product in quantity and also causes the sand to become more coarse due to lost fine grains, resulting in reduced sand quality. With the use of hydrocyclones, only the fine mud is being separated from the sand. This increases the production quantity and quality of the sand at the same time. Hydrocyclones create a vortex and make separation by using the momentum difference of sand and water.  Hydrocyclones are used together with slurry pumps and dewatering screens.

BUCKET SPIRAL SANDWASHERS

Spiral bucket sandwashers work much more efficiently than regular bucket washers. Since the spiral blades in the water pool at the back of the bucket washer drag the fine sand escaping with the water back to the buckets, the loss of fine material is very low and it is possible to produce very high quality washed sand. The slurry poured from the buckets into a dewatering screen, where it is discharged completely drained. Spiral bucket sandwashers require much less fresh water than hydrocyclones, in addition to sand washing as efficient as hydrocyclones. Considering that both providing clean water and dirty wastewater are problems with these features, spiral bucket washers become the ideal solution for sand washing.
