Abstract

L'invention concerne un concasseur effectuant un concassage pour la préparation d'échantillons. Un dispositif de broyage du concasseur comprend une pluralité de cuves de matériau hermétiques, et chacune des cuves de matériau hermétiques comprend une partie cuve principale, un marteau de concassage et un couvercle de cuve. La partie cuve principale consiste en un cylindre à l'intérieur duquel est présent un évidement incurvé. Le marteau de concassage est une demi-sphère présentant une distribution de densité dans laquelle la densité au niveau d'une extrémité supérieure est supérieure à la densité au niveau d'une extrémité inférieure. Le couvercle de la cuve est creux. Une ouverture est disposée au niveau d'une partie inférieure du couvercle de la cuve, une entrée d'alimentation est disposée au niveau d'une partie supérieure du couvercle de la cuve, et une pluralité de blocs de concassage cylindriques sont disposés à l'intérieur du couvercle de la cuve. Le concasseur pour la préparation d'échantillons présente une structure améliorée des cuves de matériau hermétiques, de telle sorte que des matériaux peuvent être grossièrement concassés à l'intérieur du couvercle de la cuve, puis finement concassés dans la partie cuve principale, ce qui permet d'améliorer l'efficacité du concassage.
