River pebbles are a common stone material, usually used in building decoration, and can also be used as raw materials for artificial sand. After being processed by sand making equipment, river pebbles can completely replace river sand for concrete aggregate, high-speed railways, railways and other industries. If there is a reasonable sand making process and high-quality sand making equipment, the sand and gravel made by river pebbles will have good quality and higher market value.

 

Overview of river pebble sand making process

River pebble sand making needs to go through four steps: feeding, coarse crushing, fine crushing, and sand making. The main equipment required is jaw crusher, impact crusher or cone crusher, sand making machine, and auxiliary equipment includes feeder, conveyor, vibrating screen, and dust removal and noise reduction device if local environmental protection is strict.

 

Process overview: First, river pebbles are evenly fed into the coarse crushing jaw crusher through a vibrating feeder for coarse crushing. The crushed river pebbles are sent to the cone vibrating screen for screening by a conveyor. The river pebbles that meet the requirements of the impact crusher are sent to the impact crusher for fine crushing, and then enter the sand making machine for sand making. After the sand is made, it is screened again by circular vibration. The sand and gravel that meet the requirements are sent to the finished product pile by a conveyor, and those that do not meet the requirements are processed again until they meet the requirements of the finished product.

 

Impact crusher and cone crusher are both secondary crushers, why choose impact crusher

Although cone crusher can also be used as secondary crushing equipment to replace impact crusher, the finished product of cone crusher is mostly needle-shaped, and the particle shape is relatively not as good as impact crusher. Cone crusher is suitable for large-scale mining industry with low requirements for discharging and large output; impact crusher is suitable for small and medium-sized stone factories with strict requirements on the particle size of sand and gravel aggregates. The finished product can replace river sand for engineering construction.

Cone crusher has a large crushing volume and slightly worse particle shape.

The finished product of the impact crusher has good particle shape and can be used for high-standard construction sand.

 

In addition, the investment cost of the impact crusher is much lower than that of the cone crusher. If you want to create a reasonable river pebble sand making process, you must not only consider the production benefits, but also the investment cost of the crushing project. It seems simple but involves many problems. If you want to know more about river pebble sand making, you can consult the customer service online.
