Designing and production of vibrating and swinging feeders of bulk and lump materials

“Stromizmeritel” Closed JSC manufactures a wide range of the stationary installed and swinging vibrating feeders of different structure and capacity:

- piped with a front discharge (model line PVT (ПВТ));

- piped with a bottom discharge (model line PVS-0,15 (ПВС-0,15));

- tray-type with a front discharge (model line PVS (ПВС));

- tray-type with a bottom discharge (model line PVN (ПВН));

- tray-type inclined with a possibility to install the controlled shut-off shutters (model line PV8(2) (ПВ8 (2)));

- tray-type with a front discharge and a sorting grid (model line PVSR (ПВСР));

- all types of swinging feeders.

Depending on properties of materials being dosed and transported the trays of the vibrating feeders are equipped with the replaceable lining plates with different characteristics. Wearproof plates of high-carbon hard-alloy materials (HARDOX, CASTOLIN) as well as plates with polymeric coating on the basis of polyurethane are used for high-abrasive components.

Swinging vibrating feeders allow to change the direction of the materials trasporting, for example when discharging the glass mixture from a mixer into a kibble, if the glass mixture is defective, or when loading the conveyed materials into a group of hoppers or silos.

The installation of shut-off rotary gate valves on the vibrating loading and unloading feeders of the weighing dosing devices increases the accuracy of dosing and prevents the material falling from a conveying tray after the drive has been switched off. Equipment of the vibrating feeders with a sorting grid allows to separate preliminary small faction when feeding glass cullet into a crusher what essentially reduces load on the operating crusher and increases its service life.

Vibrating feeders can be equipped with control units, securing both capacity adjustment and operation in multi-speed mode in order to solve the task of the accurate dosing.

The capacity of the vibrating feeders depends on the width or diameter of the tray (changeable from 50 up to 780 mm), length of the tray (from 570 up to 3000 mm) and is 0,8…80 m³/hour subject to material properties and structure characteristics.

It is advisable to use the tray-type swinging feeders produced by “Stromizmeritel” Closed JSC for unloading of lump materials with changing humidity and different particle sizes (dolomite, limestone, sand frozen together, glass cullet). The capacity of such feeders is 50-70 m³/hour and can be changed by means of a frequency-regulated drive or by changing of the crank mechanism stroke.
