250TPH Pebble Crushing Plant

Pebble Crushing Project Profile

Because of the insufficient supply of natural sand and heavy demand on high-quality machine-made sand, the customer decided to invest abundant pebble to produce machine-made sand. After knowing related information, SBM built a complete pebble crushing production line for the customer. The project brought considerable economic profits to the customer with annual gains reaching 15 million yuan.

Introduction of Pebble Crushing Technology

3-stage Crushing Scheme --- Jaw Crusher+ Cone Crusher + VSI5X Sand-making Machine

To avoid threat posed by rigid pebble to the wear-resistant parts like jaw plate, board hammer and counter-attack board, we recommended the crushing equipment whose working principle is lamination crushing to reduce abrasion of wear-resistant parts. The typical configuration of lamination crushing is two-stage jaw crushers or coordination of jaw crusher with cone crusher.

If customer puts strict demand on the shape of finished product, we would recommend a sand-making machine for crushing and dressing, which forms a 3-stage crushing mode. Although this mode leads higher investment expenditures inevitably, the production costs can be reduced greatly in the long term.

Introduction of Core Machines

PE750*1060 Jaw Crusher

The advanced manufacturing technology is taken. Meanwhile, by using digital processing equipment, the precision of each part of machine is kept. High-end materials strengthen resistance to pressure and abrasion to a large extent and extend the life expectancy of machines. The senior crushing principle helps increase proportion of cubic material and decrease needle-like material so the granularity is more stable and the quality of finished product is better.

CS160B Cone Crusher

On the basis of importing and absorbing the foreign technologies, SBM developed this high-performance cone crusher which integrates high swing frequency, optimized cavity and appropriate length of stroke. The working principle of lamination crushing is helpful for the emergence of material layers which function as the protection layers to reduce abrasion, extend life expectancy of quick-wear parts and increase the proportion of cubic material.

VSI1140 Impact Crusher

This impact crusher, also known as sand-making machine, was developed by connecting the latest research of German experts to Chinese specific conditions of mines. It is the domestic fourth generation of advanced sand-making machine. The maximized capacity can reach 520TPH. Under the premise of using same power, this impact crusher can increase output by 30% compared to the traditional equipment. The finished product is always characterized by good shape, reasonable granularity and adjustable fineness. It’s strongly recommended for machine-made production and dressing of material.
