High efficiency impact crusher for hard rock secondary crushing in large aggregate lines

Wear resistant blow bars with long service life non stop secondary crushing on large lines Impact Crusher Equipment Overview The DLHCS high-efficiency impact crusher is a heavy-duty secondary crushing equipment specifically designed for large-scale aggregate production lines, with a capacity of 400–600 t/h and a feed size ≤250mm (heavy-duty configuration ≤300mm). It is suitable for crushing materials with hardness ≤320 MPa, such as limestone, granite, and basalt. The equipment is powered by a 630kW motor and features a rotor of 1500×2300mm. With a high rotor speed of 1000 r/min, it achieves high crushing efficiency. The KMTBCr26 alloy blow bars have a 25% longer service life. Hydraulic cavity opening and discharge adjustment provide convenient maintenance. An automatic lubrication system eliminates manual greasing. The crusher has been validated in benchmark projects such as the 3,000 t/h aggregate line in Pingdingshan and the 10,000 t/d crushed stone line in Chengde. It is a reliabl…
