A construction waste production line in Xi'an is currently undergoing the production of secondary construction waste. The Dahua Heavy Industry Equipment has met the requirements for crushing and recycling in this construction waste production line battle. The equipment used in the field is the type. Crusher, impact crusher, sand making machine and other equipment, combined with the treatment status of construction waste, improve the crusher cavity type and internal structure, higher output than ordinary crushing equipment, low energy consumption and durable equipment. After coarse crushing, medium fine, fine crushing, and screening a series of processes, the material particles reach 0-5mm, 5-10mm, 10-20mm, 20-30mm, and the particles are even and full, which has been well received by users.
