FIELD: crushing or grinding of various materials.
SUBSTANCE: group of inventions relates to upper frame of crusher, cone or gyrator crusher with such frame and plant, which can be used in processing of mineral material. Upper frame comprises central bushing for crusher main shaft input, upper rim and spider-like bracket with inner walls, outer walls and bottom. U-shaped cavity passing in direction of lower flange from upper rim is limited in arachnid bracket by inner walls and bottom and passes from central bushing at least below upper rim. Cone or gyratory crusher is characterized by that it comprises the above frame. Plant for processing mineral material is characterized by making crusher with said upper frame.
EFFECT: use of improved upper frame improves manufacturability of crusher and installation with such crusher as a whole during processing of mineral raw material.
