River Stone Sand Making Plant in Philippine|(Model Number Enclosed)

River stone, also named gravel or pebble, has excellent hardness and wear-resistance, stable chemical property as well as good compression and corrosion resistance. Besides, it is easily obtainable with a simple sand making process and high-value production. Therefore, river stone is always as the raw material for construction.

We go to get river stone sand from the sand making machine after crushing, screening and other processes. The processed river stone is usually used in concrete widely for road construction, building, bridge construction, water conservancy and hydropower and other fields.

Why Artificial Sand?

Perhaps some people will ask, artificial sand is likewise a kind of sand and why is it the replacement of natural sand? Isn't it more convenient to use the exited sand, natural sand, which also reduces the cost of sand making machine?

The artificial sand produced by sand making machine has more advantages in terms of both material properties and reserves:

First, in terms of the material property. artificial sand has a more irregular particle. This results in better adhesion and pressure resistance and longer service life than natural sand. Besides, artificial sand comes from specific ore, and there are few impurities.

Secondly, as it is known that various countries have paid increasing attention to infrastructure, the demand for construction raw materials is improved with it. A warning light of natural sand reserve has been on. To protect the environment, governments have restricted the exploitation of natural sand. While artificial sand is got from various stones or even construction waste. 

To some extent, the substitute for natural sand is a matter of nature.

Process of River Stone Sand Making

The sand making machines mainly used in the Philippine river stone sand making plant are crushers, sand makers, sand washer and other auxiliary equipment. In the production of river stone sand, jaw crusher and cone crusher are used as the crushing pioneer to crush too large river stones into smaller particles to meet the size of sand maker feed port.

1. The vibrating feeder feeds the river pebble into the jaw crusher and cone crusher. Materials discharged from the jaw crusher are of about 40mm and those discharged from cone crusher are of about 10-20mm, which meet the feed requirement of the following process;

2. After the screening, the materials meeting the feed size is transported into the customized VSI sand maker by conveyor belt, and the unqualified ones are returned to the crusher for another crushing. Here the aggregates from the river stone sand makers are about 0-5mm;

3. Vibrating screener finishes another screening to the materials discharged by the VSI sand making machine. Qualified products are sent into the sand washing machine and then we get the final products. The unqualified particles are sent back to the sand maker to be crushed again till they meet the requirements.

What is Used in Philippine River Stone Sand Making Plant?

In the river stone sand production line, two types of mostly used sand crushers are jaw crusher and cone crusher. These two types of crushers have high crushing efficiency to hard materials with high output, which can meet the production needs of the VSI sand making machine.

Besides, the VSI sand making equipment has certain requirements on the fed material size. Together with the jaw crusher and cone crusher, VSI sand maker will increase the efficiency of the whole sand production line.

Jaw Crusher—Primary Crushing Equipment

As the primary crushing equipment, the jaw crusher mainly plays a part in producing a smaller size of aggregates which is suitable for the following process and improves efficiency. It uses the impaction and compression between the moving and fixed jaw to break large river stones.

The maximum feed size of the jaw crusher is between 125-1200mm, which can meet the production requirements of 1-1000TPH. For its remarkable crushing effect on hard materials and low one-time investment, the jaw crusher is the most widely used in the crushing line and sand production plant.

Cone Crusher—Secondary Crushing Equipment

Similar to the jaw crusher, cone crusher is also often used to break hard materials and it completes the last process of sand making machine. Different types of cone crusher machines have the same working principle, which is to crush the raw materials by lamination. This working method produces smaller mechanical wear to the wear parts. Compared to the impact crusher, cone crusher is more suitable for processing hard materials like river stone with higher efficiency.

According to the internal structure and the assistant device, cone crushers are classified into single-cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher, hydraulic cone crusher, etc. Cone crusher uses the eccentric shaft sleeve to drive the movable cone to rotate. And the extrusion and impact between the movable cone and fixed cone realize the crushing. Cone crusher produces cubic products with uniform size, which is incomparable by other crushers.

VSI Sand Making Machine—Customized Sand Maker

VSI sand making machine is a new type of sand machine, also known as an efficient vertical shaft impact crusher. As the core equipment in the river stone sand production line, river stone VSI sand machine can be customized according to customer needs.

The acceleration of the impeller is utilized to eject the material on the material liner. After times of rebinding, the raw materials are impacted, ground and discharged when the particle meets the final requirement.

Compared with the traditional sand machine, river stone VSI sand making machine has the following advantages:

• Large volume. The design of a deep crushing cavity has improved the throughput and the crushing efficiency, which meets higher requirements.
• Easy to maintain. The hydraulic cover device facilitates the examination of VSI sand maker and reduces the difficulty of daily maintenance.
• High crushing rate. The crushing chamber of "stone to iron" is adopted, which greatly improves the crushing efficiency.

Sand Washing Machine—Sand Cleaning Equipment (Selectable)

The sand washing machine is also called sand cleaning machine. It is used in construction sites, aggregate factory and other fields to clean or grade sand and stone with a large capacity. Based on the working principle and appearance, there are mainly spiral sand washing machine, wheel sand washing machine, etc. The wheel sand washing machine is a new type and mostly used sand cleaning machine recently.

The wheel sand washing machine is used in the pebble sand making plant in Philippine. When it works, the wheel rolls like a windmill under a certain speed. Sand in the washing tank tosses with the rotation and the impurities and foreign bodies with a small specific gravity are taken away by water.
