The screw conveyor (screw) — the transporting mechanism intended for movement within a production cycle the melkofraktsionnykh of materials where the working body is presented in the form of the rotating screw. Among the moved structures loose, including dust-like, powdery and melkokuskovy materials.

The possibility of movement of the listed freights as in the horizontal direction, and at an angle up to 60 degrees allows to use the screw conveyor practical in all industries, including:

• Production of construction and other materials, including cement and sand;
• Agriculture, including compound feed movement;
• Food industry;
• The flour-grinding industry - movement of grain, products of his processing, etc.

The special screw mechanism which is intended both for horizontal and for vertical cargo transfer allows to level need of attraction of manual skills completely. The screw conveyor (screw) independently regulates freight feed rate without use of additional power of the motor.

Screw conveyor price and classification

The screw conveyor, which price is formed depending on a type of the equipment, the melkofraktsionnykh of materials in large volume from a loading opening to unloading is optimized under the accelerated transportation and giving.

In operation of the screw the special line of movement of freight from the place of storage to batchers (the mixing cars) is used. The main operating device — the screw office placed in the closed trench. Each section on the screw is supplied with branch pipes of unloading and fibers of loading. On large productions on the screw conveyor the operating converter which operates the power and speed of work in addition is installed.

On condition of use of multipoint giving the screw conveyor can be used also for collecting various materials on the big square.

The screw conveyor is classified by the following angles of movement of freight:

• horizontal;
• pologonaklonny;
• krutonaklonny;
• vertical.

Also conveyor screws are subject to additional classification:

• continuous;
• tape;
• scapular;
• shaped.

The most popular screw conveyor — the price and power the main criteria — shnekovy as is the mechanism of continuous work at small expense of the electric power.

Production of screw conveyors

Production of screw conveyors is carried out with the quality mark of GOST and in various climatic types — T (tropical) and At (moderate).

Shnekovy conveyors at the correct settlement installation are capable to work continuously that is promoted by simplicity of the mechanism and reliability of his operation.

The conveyor consists of the following parts:

• special case;

• bearing support;

• loading and unloading trenches (openings);

• bearing support;

• driving electric motor;

• connecting flanges.

Process of loading/unloading happens as follows — material due to operation of the screw through loading openings moves to unloading. When unloading material we will allow a tilt angle to 25 degrees.

Production of screw conveyors is required in those industries where movement of small freights in large volumes is required, at the same time exist to restriction on freight type.

The following materials are forbidden to transportation:

• sticky

• condensed

• abrasive.
