Embodiment Construction

[0024] exist figure 1 In , a vertical shaft impact crusher 1 is shown in partial section. The rotor 2 is located in the housing 4 of the crusher 1 . At the top of the crusher 1 a feed hopper arrangement 6 is placed. The feed hopper arrangement 6 has a hexagonal inner hopper 8 and a hexagonal outer hopper 10 surrounding said inner hopper 8 . figure 1 A cover, not shown, seals the space 12 formed between the inner hopper 8 and the outer hopper 10 from above. The hopper 8 is provided with six outlets 14, each such outlet 14 being placed at one side of the hopper 8 inside the hexagon. Each outlet 14 is provided with a movable flap 16 . The movable flap 16 can be placed at different positions on the inner hopper 8 to obtain the desired opening area of ​​the respective outlet 14 . In said space 12 , near each outlet 14 , an "L"-shaped directional arm 8 is fixed between the inner 8 and outer 10 hoppers. Below the inner hopper 8, a central feed cylinder 20 is placed. The feed c...

Abstract

A vertical shaft impact crusher comprises a rotor for accelerating a first flow of material to be crushed, a first feed means for feeding the first flow of material to the rotor, a housing against which the accelerated first flow of material may be crushed, and a second feed means for feeding a second flow of material to be crushed into the path of the accelerated first flow of material. The second feed means comprises an inner hopper (8) and an outer hopper (10). An outlet (14) is formed in said inner hopper (8) for allowing said second flow of material to enter a space (12) formed between said inner and outer hoppers (8, 10). A slide plate (36) is located in said space (12) adjacent to the outlet (14), the slide plate (36) being inclined in a direction being substantially tangential in relation to the rotor.

Description

technical field [0001] The present invention relates to a vertical shaft impact crusher for crushing material, said crusher comprising: [0002] a rotor for accelerating the first flow of material to be crushed, [0003] a first feeding device for vertically feeding the first stream of material to the rotor, [0004] a housing comprising a circumferential impact wall portion against which the accelerated flow of the first material can be broken up, and [0005] A second feeding device for feeding the second flow of material to be crushed into the path of the accelerated first flow of material. Background technique [0006] Vertical shaft impact crushers (VSI crushers) are used in many applications to crush hard materials such as rocks, ores, and the like. WO 2004 / 020103 describes a VSI crusher comprising a housing and a horizontal rotor inside the housing. Two separate streams of material can be fed to the crusher. The first material is fed to the rotor through openings...
