在人工制砂行业，竖直轴冲击破，也称为制砂机，被广泛作为主要的制沙设备。制砂机的破碎方式有两种：“岩石对岩石”和“岩石对铁”。但许多人并不十分清楚这两种破碎方式的区别。本文主要介绍制砂机的这两种破碎方式及其比较。

适用情况比较

Generally, “rock on rock” crushing method is used for shaping and “rock on iron” crushing method is used for sand making.

The “rock on rock” crushing method is suitable for crushing abrasive materials with medium hardness and above, such as basalt, etc. During the crushing process, materials injected from the impeller impacts the material liner and do not directly contact the metal components of sand making machine, reducing iron consumption and thus reducing maintenance time. The shape of the finished products is good under the crushing method of "rock on rock".

The “rock on iron” crushing method is suitable for crushing abrasive materials with medium hardness and below, such as limestone, etc. Under the “rock on iron” crushing method, sand making machine has high efficiency.

工作原理比较

2 crushing methods of sand making machine

制砂机 (also known as "Sand Maker") have two feed modes – "feed at center" and "feed at center & sides". Generally, “feed at center” feed mode is used in “rock on iron” crushing method. In this condition, the vertical shaft impact crusher is used for sand making and has low production capacity. “Feed at center & sides" is used in “rock on rock” crushing method. In this condition, the vertical shaft impact crusher is used for shaping and has high production capacity.

主要耐磨件比较

Sand making machine with “rock on rock” crushing method and sand making machine with “rock on iron” crushing method has different main wear-resistant parts.

Under the crushing method of “rock on rock”, materials form a material layer around the impact block and the materials impact on the material layer and are crushed. So, the main wear-resistant part of sand making machine with “rock on rock” crushing method is impact block.

在“铁上岩”破碎方法中，冲击块被轮缘护板取代，材料直接冲击轮缘护板并被粉碎。因此，采用“铁上岩”破碎方法的制沙机的主要耐磨零件是轮缘护板。
