Can river pebbles be used as sand after breaking? What equipment is needed to prepare it?

River pebble is a common natural stone, widely used in construction, road, water conservancy and other projects. However, for some projects that require finer sand, river pebbles need to be broken to meet the requirements. This paper will discuss whether the broken river pebble can be used as sand material, and the equipment required for the preparation process.

Can broken river pebbles be used as sand?
The answer is yes. Sand with certain particle size and shape can be produced by crushing of river pebbles. This kind of sand can be widely used in the fields of concrete, subgrade filler, artificial sand and gravel.

What are the pebble sand making equipment?
The preparation of river gravel sand requires some specific equipment for crushing and screening. The following are commonly used river pebble sand making equipment:

1, jaw crusher: jaw type sand crusher feed particle size of up to 1500mm, can handle 1-1000 tons of river pebbles per hour, strong pressure resistance, often used to deal with ore above medium hardness.

2, impact crusher: suitable for medium hardness, soft material (limestone, coal gangue, etc.), repeated impact between the plate hammer and the impact plate for crushing, new structural design, machine rigidity, rotor has a large moment of inertia, the finished product is a cube, no tension and crack, good grain shape, high comprehensive benefit.

3. Sand making machine: the roller sand making machine is the roll crusher we often say, which can be medium and fine crushing of medium hard and soft ore. After extrusion crushing of the roller sand making machine, the diameter of the sand reaches 5mm or less, which is mostly used in building materials, construction and other places where the sand aggregate is strictly required.

The production capacity of the roller sand making machine ranges from 2-240t/h, according to the size of the production capacity, it can be divided into large, medium and small roll sand making machine, the production capacity is above 100t/h is a large roll sand making machine, the production capacity is 40-90t/h is a medium-sized roll sand making machine, and the production capacity is below 40t/h is a small roll sand making machine. The roller sand making machine has a long service life, and only needs to replace the worn part, which also reduces the cost, and is the most advanced sand making equipment at present.

The above equipment can be used in combination according to actual needs to achieve the desired sand particle size and shape.
