This series of equipment widely used, its performance has reached international advanced level, is the most effective, practical and reliable stone machine, especially for the production of abrasives, refractories, cement, quartz sand, steel grit, slag powder, copper ore, iron ore, gold ore, river gravel, concrete aggregate, asphalt and other aggregates, crushing brittle material and the broken, is a highly efficient, energy-saving equipment, sand gravel, sand making energy-saving than traditional 50%, is the world's cage of sand equipment. Characterized by small energy consumption, high output, crushing ratio; devices are small, simple operation, easy installation and maintenance, with a shaping function, the cubic-shaped product, packing density: the production process, the stone can form a protective low-rise, body no wear, durable; a small amount of wear parts made for extra hard wear-resistant material, small size, light weight, they and replacement parts.
