River stones are mainly river red stones or materials, such as river gravels, boulders, cobbles, and river sands. These river mixed aggregates are mined, and then transported to the stone quarry for crushing.
In quarry, river stones are crushed by rock crusher machine into small dust, general there are four types of crushed river aggregates screened out from vibrating screen .
Coarse sand: 0.6 mm – 2 mm
Fine gravel: 2 mm – 6 mm
Medium gravel: 6-20 mm
Coarse gravel: 20-60 mm
River stone crushing & screening plant
River stone crushing plant is the major crushing unit to process river stones like cobble rocks, pebble, sand & gravel, silica etc. It involves crushing, screening and washing process.
NFLG machinery is a major river stone crushing & screening equipment manufacturer and exporter in China, the widely used stone crushing machine are: jaw crusher , impact crusher , cone crusher , VSI crusher, vibrating screening, belt conveyor etc.
Flow chart of river stone crushing plant:
Bulk raw river stone is mined from the deposits on the river bed, then transported to the river stone crushing & screening plant.
At the plant, raw river stone will be fed into jaw crusher for primary crushing by vibrating feeder . After primary crushing, the material will be transferred to secondary crushing equipment like impact crusher for further crushing.
Usually, we will equip the river stone crushing & screening plant with multi-deck vibrating screen. The vibrating screen is a key equipment to sieve the crushed stones into different grades.
The crushed stone meet the demands will be transported to the stockpile, the other will be sent to cone crusher or impact crusher for fineness crushing.
River stone crushing plant:
River stone screening plant can separate sand, granule, pebble, cobble from the mixture. The final grain sizes of river stone crushing plant are: 0-2mm, 2-4mm, 4-8mm,8-16mm, 16-30mm, 30-45mm, 45-64mm and larger.
According to the application, we design the proved river stone crushing & screening plant of 40-80 TPH, 80-120 TPH, 120- 200TPH, 200-300TPH, 300-450TPH, 450-600TPH, 600-800TPH, 800-1000 TPH etc. for the contractors and clients.
River stone crushing system includes stationary and mobile crushing unit, producing aggregates and artifical sands substitute of river sand for road building construction.
Crushing machine used in river gravel plant
In quarry, the complete crushing plant is used for crushing and screening the appropriate river aggregates. It general includes three crushing process and one screening process.
Jaw crusher is mainly used for primary crushing in river stone coarse crushing unit. The capacity of large scale jaw crusher can be upto 400-800 tons/hour, while small jaw crusher is 1 t/h. So, according to the capacity of crushing plant, choose the right scale of jaw crusher.
Impact crusher can crush river stones with diameter 350 mm into small particles with diameter 20-60 mm in medium crushing process. Our impact crushers have 4 or 8 hammers, and the crushed stone materials are in cubical shape.
Cone crusher is mainly used in fine crushing unit. CS cone crusher is the most common cone crusher. Compared with other models, CS cone crusher with high-efficiency has long crush arms, long impact distances, high crush powder, and can crush the materials in the chamber efficiently. Hydraulic cone crusher is the newest cone crusher. Owing to the change of the concave’s style and the protect of the crushed products, the abrasion of the machine is reduced greatly and can last long compared with the old cone crusher.
Vibrating screen is the screening machine in stone crushing plant. It can screen out the appropriate dusts using the right sieve pore size of screen according to the requirements of size.
There are other quarry equipments such as belt conveyor, sand washing machine and vibrating feeder used in river stone crushing plant.
If you want to get artifical sand substitute of river sand, you must add vsi crusher after medium crushing process. It has two funtions: sand making and stone shapping, so it is also called sand making machine or stone shapping machine.
