Spiral classifiers or dehydrators (Spiral classifier) ​​are devices for classifying granular materials by coarse and for coarse drainage. Water is used as a classification medium. The classification of fine particles of solid materials is based on the rate of fall of particles in water or air. Larger particles fall faster than smaller ones due to their larger masses. Spiral classifiers can also be used to wash ore materials.

This classifier board consists of a trough with a nasal structure, a spiral, a drive and transmission mechanism and an overflow threshold.

The trough of the classifier is made of sheet steel, and is characterized by its: length, width, angle of inclination and height of the overflow threshold.
Send washers with spiral
The dehydrator is a spiral classifier that serves to separate the 0-4 mm (0-2 mm) fraction from water after washing the material on vibro screens. The fraction, which has settled at the bottom of the riverbed, is pushed by a spiral towards the upper end of the riverbed. The classifier overflow usually contains 60-80% of the fraction below 0.1mm. Depending on the length of the trough, the moisture content in the finished fraction also changes. In practice, a moisture content of 20-25% is achieved. In order to extend the service life of the spiral, we can protect it by installing wear-resistant steel coatings or plastics - polyurethane
Send washers with buckets
A bucket dehydrator is a device that, like a spiral dehydrator, improves the quality of sand by washing pieces of earth and other impurities out of the sand. It is characterized by high output capacity, low energy consumption, low loss of material to be washed and good washing quality.

The material that reaches the dehydrator together with the water is transported by a snail, to the initial part of the spiral on which the buckets are symmetrically arranged. The buckets capture the material and take it out of the machine, and the water drains through the perforation of the buckets.

This type of dehydrator is equipped with a speed regulator, and by adjusting the speed of the spiral, the capacity and quality of rinsing can be fine-tuned. The machine itself is very robust, with self-adjusting spherical bearings at the ends of the spiral.
Send washer for washing materials - dehumidifiers
Dehumidifiers are devices used to wash useful material (ore) from earth or clay. They can accept material up to 60 mm in size. Two spirals with blades are placed in the trough of the dehumidifier, which rotate synchronously. With the addition of water, aggressive washing of materials and removal of the most sticky clays is performed. It is recommended to separate the 0-4 mm fraction from the material before desoldering, because it significantly reduces the washing effect of the material. The angle at which the dehumidifier is placed depends on the degree of soiling of the material and ranges from 0-14 degrees.
Mehanika as a company independent of the Aleksinac coal mines first started operating in 1976. Based on the experience and knowledge gained in the maintenance of equipment for coal mines, in 1980 it began a more intensive development in the manufacture of machines and complete plants. Since then, a large number of machines with their subtypes have been adopted. Along with intensive development, machinery and equipment are also exported to other countries. We are able to offer you plants with a capacity of 20 m3 / h to 100 m3 / h. If you need any additional information, do not hesitate to contact us.
