The first step in choosing a primary crusher takes place at a high level. It's necessary to identify the purpose the crusher will be used for. This purpose is a given that precedes the entire decision-making process. Sometimes, a measure of guidance or experience is needed. The two main components to consider when identifying purpose are feed ...

The Moving Sawmill. Rating: 7/10 Reasoning: A reasonably efficient crusher, capable of doing decent damage to vehicles of all sizes, and can sometimes completely destroy smaller vehicles. The Wrecking Ball. Rating: 7/10 Reasoning: This crusher had similar strength to the Spinning Hammer. It could one-shot small and …

stone crusher is commonly used in coal washery and coking plant. The stone of this crusher is the easiest wearing spare part which is often made of high manganese steel. After water toughening, the hardness of the high manganese steel is 180~220 HBW, and its property is that under the big squeezing force or impact load, its working surface will ...
