冲击式破碎机和圆锥破碎机有什么区别?

一般而言,冲击式破碎机包括垂直轴(VSI)和水平轴(HSI)两种,主要与圆锥破的区别在于破碎力的类型。冲击式破碎机通过材料撞击另一物体进行破碎。圆锥破采用压力破碎,将物料夹在两个破碎面之间进行挤压或压碎。对于任何应用来说,破碎机的类型和破碎工艺的选择取决于物料的硬度、物料密度、给料尺寸、所需产品尺寸和容量,以及每种破碎机的初期成本和维护成本。

基本结构与工作原理

水平轴冲击破碎机由料斗、两个或三个挡板、转子和击打棒或锤头组成。基本上,大块的物料被送入料斗,在那里与锤头或击打棒接触,进入旋转的转子,将物料粉碎成更小的部分。当较大的物料被锤头碰撞时,会与每个挡板接触并反弹回旋转的锤头,进行另一轮冲击,直到物料从HSI排出。

竖直轴冲击破由进料料斗、进料管、转子以及固定的冲击块或岩石挡板组成。本质上,进料物料通过进料管落入转子,转子通过离心力将物料高速抛向由复合金属合金或岩石(通过安装岩石挡板)组成的固定冲击块。当岩石撞击冲击块或岩石挡板时,会沿着自然应力线碎裂,形成均匀的立方体产品。

圆锥破碎机s consist of a bowl liner, a mantle, both main shaft and frame, compression, and an eccentric inner and outer bearing. Essentially, material is reduced in size by squeezing the material until it breaks. Specifically, the material is compressed between a moving piece of steel, the mantle, and a stationary piece of steel, the bowl liner. The final product’s size is determined by the closed-side gap setting between the two crushing members at the bottom. As the cone eccentrically rotates, the material is crushed and works its way down through the crushing chamber, until it discharges at the bottom of the machine.

破碎工艺的材料组成

为了了解圆锥破碎和冲击破碎流程,必须了解将要破碎的材料,这将决定最适合您业务需求的破碎机。在考虑要破碎的材料时,您必须考虑其磨蚀性、硬度、密度、细粉含量以及您期望的成品粒子形状。

冲击式破碎机s are used to crush softer, less dense and abrasive material such as limestone. Because of its consistent striking process, an 冲击式破碎机 produces uniform cubical finished 产品, which are desirable for hot asphalt producers. Depending on the application, 冲击式破碎机s can have higher wear costs, higher maintenance, and produce more fines. 冲击式破碎机s may be used as a primary, secondary, or tertiary crusher depending on the producer’s final-product-size needs. These crushers are available in stationary, track and mobile designs. Another industry usage is slag, specifically blast furnace slag, which is less abrasive than steel furnace slag and can be broken down if processed through an 冲击式破碎机.

圆锥破碎机主要用于破碎较硬、更具磨蚀性和密度大的物料,例如用于建筑、化工、冶金和硅酸盐行业的花岗岩。圆锥破碎机可用于一、二、三级破碎。这些破碎机有固定式、履带式和移动式设计。圆锥破碎机还用于钢铁炉渣行业,其炉渣比高炉渣更具磨蚀性。

冲击式破碎机,起初比圆锥破碎机便宜。虽然圆锥破碎机的前期投资更高,但它们所需的维护远少于冲击式破碎机。冲击式破碎机的主要维护成本来自于击击板和护板的磨损,如果用其来破碎高磨蚀性材料,可能会超出圆锥破碎机的初始成本。如前所述,生产商必须了解他们的行业需求以及他们将开采的材料,以选择最合适的破碎机。
