1. One machine is multi-purpose, especially suitable crushing and recycling of building concrete and mou road construction, with good flexibility and cost adv 2. Adopt advanced hydraulic technology, use hydrau motor to drive the jaw plate to rotate, crush concret stones, etc., to meet the set requirements. 3.Crushing jaw plates can be easily replaced on-site. The jaws are identical and can be ro tated 180 degrees to even out wear. 4.Efficient Work Optimal design of jaw plates bring higher efficient of crushing. Saving fuel consumption by minimized operating system.
