Screw conveyors of series "VK": type VK 114, VK 159, VK 219, VK 273

The screw conveyors of series "VK", produced by machine building enterprise Stroymechanika is intended for horizontal and inclined transportation of the powered, granular and small-sized bulk materials. The screw conveyors are used as a feeders, batchers and mixers.

The simplicity of the design, high output, reliability and unpretentiousness of screw conveyors provide theirs large application in different fields of activity connecting with transportation of large volumes of bulk materials.

The crew conveyor consists of the following assemblies and parts: body (1), screw (2), bearing support (3), loading and unloading opening (4) with connecting flanges (5), reducer (6) and drive electric motor (7) (Fig.1). Having rotated the screw the conveying material enters from loading opening to the unloading opening.

Depending on the requirements for the screw conveyors installation in the technological line the drive of the conveying screw can be made according to the jogging schema (TL), and to the towing schema (TN).

Applying the jogging schema, the drive of the conveying screw is installed from the side of loading opening. The specified schemas of the drive installation of the conveying screw doesnt effect the output of screw conveyor and are prescribed taking into consideration access conditions to maintain screw conveyors.

Depending on the material characteristics to be supplied the screw conveyor can be equipped with spiral or ribbon screws. So, the spiral conveying screw is used () to convey very bulk materials such as cement, sand, gypsum, chalk, sinter, powered lime. The ribbon screw (L) is more wisely used to convey lump material such as gravel, limestone, non-granular slag (Fig.3)

The industrial enterprise Stroymechanika develops, manufactures and supplies screw conveyors of generally industrial purpose of type VK 114, VK 159, VK 219 and VK 273, intended to convey small-sized, granular, powered, explosion proof, non aggressive materials of different origin.

According to the customers demand the screw conveyors can be equipped with jogging or towing screw drive.

The design of loading and unloading branch of the screw conveyor can be typically made. (Fig. 7) or can be modified according to the customers demand. The loading and unloading branches have connecting flanges (Fig. 4) to connect screw conveyor to the storage bulk materials hoppers, mixers, batchers and others. The design of the connecting flanges of screw conveyors of standard set allows to install manually operated disk shutters and shutters with drive.

The screw conveyor of type VK 273 can be made 1000-12000 mm by length. The screw conveyor of type VK 159 is made from 1000 up to 9000 mm. As a standard model the screw conveyor of machine building enterprise Stroymechanika are made: type VK 273 - 5000 mm, type VK 159 - 3000 mm. The screw conveyors of machine building enterprise Stroymechanika are traditionally equipped with motor reducer of import production. So, all screw conveyors are equipped with motor-reducer MU 110 by SITI (Italy) production. The screw conveyors of machine building enterprise "Stroymechanika" are equipped with a impulse counter and start-up electric equipment that allow to use screw conveyor to batch bulk materials
