Embodiment Construction

[0041] figure 1is a sectional view and schematically shows a crushing device including a horizontal shaft impact crusher 1 (HSI crusher). The horizontal shaft impact crusher 1 comprises a housing 2 in which an impeller 4 is arranged. A motor, not shown in order to preserve the clarity of the drawing, is operable to rotate the horizontal shaft 6 on which the impeller 4 is mounted. Instead of the impeller 4 being fixed to the shaft 6 , the impeller 4 is rotatable about the shaft 6 . In either case, the impeller 4 is operable to rotate about a horizontal axis coinciding with the center of the horizontal shaft 6 .

[0042] The material to be crushed is fed into a horizontal shaft impact crusher feed chute 8 mounted to the inlet flange 9 of the housing 2 and into a crushing chamber 10 arranged inside the housing 2 and at least partially surrounding the impeller 4 . The crushed material leaves the crushing chamber 10 via the crushed material outlet 12 .

[0043] The casing 2 is ...

Abstract

A crushing device comprises a horizontal shaft impact crusher (1) having an impeller (4) rotating around a horizontal shaft (6) and at least one curtain (16, 18) against which material may be crushed. The crushing device further comprises a first feeding device (109) for feeding a first type of material to be crushed to a crushing chamber (10) of the horizontal shaft impact crusher (1), a second feeding device (117) for feeding a second type of material, having a smaller average particle size than the first type of material, to the crushing chamber (10) simultaneously with the first feeding device (109) feeding the first type of material to the crushing chamber, and a mixing arrangement (8, 54) for least partially mixing the first and the second types of materials with each other before bringing them into contact with the impeller (4).

Description

technical field [0001] The invention relates to a method of feeding material to be crushed into a horizontal shaft impact crusher comprising an impeller rotating around a horizontal axis and at least one curtain against which the material can be pushed. Fragmentation is performed by the at least one baffle. [0002] The invention also relates to a crushing device comprising a horizontal shaft impact crusher having an impeller rotating around a horizontal axis and at least one baffle against which material can be crushed. broken. Background technique [0003] Horizontal shaft impact crushers (HSI crushers) are used in many applications for crushing hard materials such as stones, ore blocks, and the like. HSI crushers have impellers made to rotate about a horizontal axis. Stones are fed towards the impeller and are struck by striker elements mounted on the impeller. The stones are fragmented by being struck by the striker elements and are accelerated and thrown towards a b...
