FIELD: mining.
SUBSTANCE: proposed group of inventions relates to a mobile screen and a mobile installation for processing of mineral material with support legs. A case of the mobile screen contains a platform frame, a set of legs for provision for the platform frame with support on the ground, a support screen frame installed with support on the platform frame and made with the possibility of being transferred between a transport position, in which the support screen frame is adjacent to the platform frame, and a working position, in which the support screen frame is lifted relatively to the transport position, and a set of supports with the first ends made with the possibility of structural connection to the support screen frame and the second ends. Supports are arranged in pairs and are located outside the platform frame in a side direction. The second ends of supports are made with the possibility of structural connection to corresponding ends of the set of legs, when the support screen frame is in the working position. The case of the mobile screen additionally contains a support hinge for structural connection of the support to the leg, wherein the support hinge contains a horizontal connecting part, which is connected to an upper part of the leg. The case of the mobile screen attached to the support screen frame is used in the mobile installation for processing of mineral material, containing a crusher attached to the platform frame and a supply device for supply of an oversize product from the screen or sieved material passed through the screen to the crusher.
EFFECT: reduction in weight and/or increase in strength of a mobile screen.
