River pebble crushed sand is a good investment project, but river pebble is not a rock that is easily broken. The hardness of river pebble is very high, and it is an excellent building material. It is estimated that the hardness of granite is equivalent to that of granite. It requires high crushing equipment, so not every manufacturer can produce such equipment.
The main engine of Henan Haogang adopts advanced crushing processes with self-shaping effects such as jaw, heavy hammer, counterattack, and impact. Its equipment is divided into fixed, mobile (tired, tracked) large, medium and small. The device can be configured according to user needs. Which uses dual-use oil and electricity, flexible switching, intelligent system, reduce energy consumption and save costs. The pre-screening unit screens out the soil and over-fine materials in advance to reduce the invalid throughput of the crusher and the workload of the subsequent screening unit.
The river pebble sand production line also needs to be explored. It is recommended that the coarse crushing operation of the jaw crusher combined with the second crushing operation of the cone crusher, followed by the circular vibrating screen, and then the high-efficiency sand making machine. This kind of operation process has a reason. The jaw crusher is used as the coarse crushing device because the jaw crusher is cheap and very suitable for coarse crushing. The cone crusher is selected because the cone crusher is laminated and crushed, and the crushing ratio is large. , High efficiency, small loss; circular vibrating screen has good screening effect, simple structure, and low price; then the sand making machine was selected because the equipment can produce machine sand with a grain shape closer to natural river sand, and the efficiency ratio is high.
