Gravel Stone is a common crushed material in geology, the following is a comprehensive programme of Gravel Stone crushing and sand making equipment, which is divided into core equipment, auxiliary equipment and configuration suggestions by combining different production requirements and technical characteristics:

Gravel Stone Crushing and Sand Making Equipment Core Equipment Configuration

Gravel Stone Coarse Crushing Equipment

Jaw Crusher

Jaw Crusher: it is used to process large Gravel Stone (diameter up to 1500mm), crushing to ≤150mm coarse material. The advantages are simple structure and high capacity (1-1200t/h). Mobile Jaw Crusher (optional): Suitable for projects that require frequent transfers, no fixed foundation, high flexibility.

Gravel Stone medium and fine crushing equipment

Impact crusher:

Impact crusher: suitable for medium and low hardness materials (such as limestone), the finished product has good particle shape and low energy consumption, handling capacity 55-750t/h.

Gravel Stone sand making equipment

Roller sand making machine

Roller sand making machine: the extrusion crushing method makes the material cracks internally, further crushing with lower energy consumption, and the finished product has even shape of the particles and low over-crushing rate. The equipment is compact, easy to operate, equipped with intelligent control system, reducing manual intervention, supporting continuous operation of the production line, and its crushing efficiency is 30%-40% higher than that of traditional equipment Low energy consumption of equipment operation, total energy consumption can be reduced by 20%-30%, to achieve a balance between energy saving and high production.

Auxiliary equipment and process optimisation

Screening equipment

Circular vibrating screen/linear vibrating screen: classify the crushed aggregate, separate the specifications such as 0-5mm sand, 5-10mm stone, etc., and the screening efficiency reaches more than 90%.

Washing equipment

Wheel bucket sand washer: removing soil and stone powder in sand, controlling MB value ≤1.4, handling capacity 50-300t/h.

Configuration plan of Gravel Stone crushing sand production line

Equipment Combination: Jaw Crusher + Impact Crusher + Rollers Sand Making Machine + Vibrating Screen + Sand Washing Machine.

Features: low investment cost, small footprint, suitable for small and medium-sized Gravel Stone plant.

Selection of medium crushing equipment according to the hardness of materials: high hardness Gravel Stone (such as basalt) preferred cone crusher, medium and low hardness selected impact crusher.

Energy-saving design: choose the equipment equipped with hydraulic system and automatic lubrication (such as single-cylinder cone breaker) to reduce the maintenance cost.
