The invention relates to a screening element for screening and transporting grit material, for applying to a sanding device of a sanding apparatus for a vehicle. The screening element includes a plate element provided with a shaft-coupling mechanism, at least one through-opening, and at least one lug. The shaft-coupling mechanism is designed to couple the screening element to a shaft device of a rotary feeder of the sanding device. The through-opening is arranged in the plate element and is designed to guide grit material through the plate element. The lug extends transversely in relation to a main surface of the plate element, away from the plate element.

A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

An integrated abrasive dispensing material system for a wheeled vehicle is provided. The system having a hopper for dispensing the abrasive material into a dispenser, and then out dispensing pipe at the bottom of the dispenser. The dispenser has a rotating brush roll actuated via a motor, the rotating brush roll having a plurality of bristled flaps extending radially from a cylinder positioned inside the hollow dispenser. The flaps ensure a constant and calculated flow of abrasive material. The flap also make contact with the interior perimeter of the dispenser keeping the abrasive material inside the dispenser in an environment that prevents moisture and cold air flow from entering the dispenser which could cause the abrasive material to form blocks that could jam the system.

A device for scattering grit in front of the wheels of a vehicle comprises a housing having a feed inlet for the grit, an outlet for the grit and a substantially cylindrical recess for receiving a brush roll which is rotatably mounted and driven about a substantially horizontal axis of rotation for the metered delivery of the grit from the feed inlet to the outlet. At least one wedge is arranged in the region of the feed inlet for the grit, in front of the brush roll and tangentially and displaceably with respect to the brush roll so that the size of the feed inlet can be adjusted.
