Vibrating Screens
Vibrating screens (eng. Vibrating screens, German Rüttelsieb) are machines that use mechanical vibrations to separate materials by granulation, into fractions. The number of fractions depends on the number of floors of the vibro sieve. Our production program includes screens that can have from one to four floors. They can be used for dry sowing or sowing with washing, with the addition of a washing system. The vibrating screen itself consists of a drive that causes mechanical vibrations, sieving surfaces that separate the material into fractions and a frame that serves as a support for the sifting surfaces and a transport path for vibrations from the drive to the sifting surfaces. The change in the sharpness of the sieve (amplitude) is done by changing the weight of the swing masses (imbalance). Depending on their position in the technological line, they are divided into primary or secondary vibrating screens. They can also be used to separate water from materials using "rhyme" nets.

Crushers
Impact Crushers (Impact Crushers, German: Prallbrecher) are devices for crushing most often stone, but also all other crushing materials. The crushing part consists of a rotor with impact beams (type MG) or with articulated hammers (type MČ) and a stator (housing lined with plates made of wear-resistant materials). Shredding is done by hitting the rotor beam or hammer on the material, and by hitting the material on the stator lining. The composition and granulation of the material at the outlet code is regulated depending on the process requirements. They are very efficient and economical when crushing.

Feeders
Feeders (Feeders, Fütterer) are devices that dose ore or some other type of substance in equal portions per unit time. They remove the material from the bunker and dose it further into the transport or processing system. They are most often placed on the outlet openings of bunkers, and at the same time serve as closures for these openings. Our feeders enable easy and precise dosing regulation, ie the amount of material they send into the processing.

Conveyer Belts
Belt conveyors (Gurtförderer, Förderband) are the most widely used continuous conveyor machines. They are used in all branches of industry for a wide range of capacities, most often for bulk materials, but they can also be used for the transport of piece materials. They can transport material in a horizontal or inclined path.

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

Storage bin snd Silo
The use of bunkers or silos as a storage space is often required in the mineral processing system. Bulk materials must be stored for a shorter or longer period of time in order to:
- uniform flow of material that is processed continuously and delivered intermittently, eg by truck or loader
- temporary storage with the aim of further distribution
- storage of necessary watering supplies

Proccessing plants
Plants for the preparation of mineral raw materials consist of machines and devices, by means of which the preparation of the respective mineral raw material is performed according to the granulometric composition for further use or further processing. Plants for crushing and grinding of mineral raw materials differ in the applied technological processes, which depend on the properties of the mineral raw material and the requirements of the users of the products of these plants. Our company is fully qualified to make the technological scheme, technical documentation, production of complete equipment and installation, according to the "turnkey" system.

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.
