River stone crusher
Aggregate for concrete is raw material for road building or construction building. In quarry, these building aggregates are made by crushing from stones from mountain or rivers.

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 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.

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.

In these three stone crushing process, different river rock crushing machines are used.

In coarse crushing unit, Jaw crusher is mainly used for primary crushing. It's crushing ratio is big, and can make big river stones into small dust. According to the capacity of crushing plant, choose the right scale of jaw crusher. The capacity of large scale jaw crusher can be upto 400-800 tons/hour, while small jaw crusher is 1t/h.

In medium crushing process, impact crusher or cone crusher are used. These two kinds of stone crushers are mainly used in secondary crushing plant. Impact crusher can crush river stones with diameter 350 mm into small particles with diameter 20-60 mm. 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. Symons cone crusher is the most common cone crusher. Compared with other models, symons 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 and vibrating feeder used in river stone crushing plant.

If you want to get artifical 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.

River stone crusher manufacturer
DSMAC is a famous mining equipment company in China, and manufacture all kinds of crushers and grinding mills for sale. We not only supply the complete crushing and grinding plant with bid prices, but also the installation and maintenance service for the customers in Egypt, USA, India, South Africa.

Product Description

Principle of operation
This machine is a breaking equipment used for breaking materials by a crushing. The device takes the rotor to do high-speed rotatory movement under the lead of the motor; When the materials entered the functional section of plate hammer, they experiment plate hammer's high-speed crushing and are throwed constantly to the reaction device installed on the rotor, then spring back to the functional section of plate hammer from the back board, and then are crushed again; The materials from big to small in the shredding breach to be broken repeatedly. Until the materials are broken to the demanded grain size, discharged from the bottom of the machine.
Performance features
It is the latest reaction breaker, This machine combines breaking and shaping together; It has the features of being high efficiency, low-consumption, good discharge grain shape, . Compared with other reaction breaker, it can reduce the energy consumption by 40%, the quatity of the aggregate needle flake can be reduced by more than 80%.
Widely applied to all kinds of materials crushing, processing and shaping, such as basalt, granite, cobble stone, limestone, etc.

Big 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 machine like impact crusher or cone 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 that meet the demands will be transported to the stockpile, the other will be sent to cone crusher or impact crusher for fineness crushing.
