Fixed crushing machine is made of latest steel, which has high wear resistance, light weight and large opening. Stable performance of oil can provide additional power to ensure its operation in various environments. Demolition equipment (primary demolition) is only first step in demolition work. During initial demolition, large chunks of recyclable concrete need to be crushed to make fragments easier to load and transport. Crushing energy is an ideal tool in work of crushing concrete. This is a very important operation.Crushed gravel can be directly recycled as building materials.Steel bars can also be kept intact and can be used again as materials for road construction. Stationary crushing can be used for secondary demolition operations and can also be used for recycling concrete materials.
