Screw spirals are used as screw conveyors for transportation of bulk materials (grains, dust, fodder products, building materials, wood, etc.). They are able to work in a horizontal, vertical or inclined position. They find applications mainly in agriculture (poultry, of dairy farms around here), the grain processing and cotton processing companies, in the production of cement, in milling, recycling of wastes, as well as in the food and meat processing industry. The screw spirals typically operate by rotating clockwise. There are right-wing and left-wing screw spirals, such as the right-wing are coiled clockwise and the left – in the counterclockwise direction. Both types of spirals can navigate a material in the same direction, if you change the direction of rotation relative to one another. This is done by inverting the polarity of the drive motor, respectively, the direction of rotation of the motor shaft, usually connected to the axis of the screw spiral.
