Stones For Manufactured Sand And Sand Production Line by OliviaFTM: 3:03am On Jun 05, 2023
At present, there are many types of stones that can be used to make sand in the mining industry, at least more than 200 kinds. Basically, as long as the added value of the ore is not high, and the water content is below a certain range, it can be used to make sand, even tailings can be made into m sand.


1. Common stones that can produce machine-made sand

1.1 River pebbles, basalt, granite, limestone, bluestone, iron ore
They are all ideal green building materials with hard texture. They can be used as raw materials for sand in sand plants.
Basalt sand is mixed in concrete, which can reduce the weight of concrete and has the effect of heat insulation and sound insulation. It is a good aggregate for lightweight concrete in high-rise buildings.

1.2 Sandstone, quartz sandstone, etc.
Sandstone is a kind of sedimentary rock, mainly composed of quartz and feldspar, whether it is strength or grain shape, it is one of the good raw materials for machine-made sand. In addition, its advantages of not being weathered outdoors, not melting in water, moisture-proof, and sound-absorbing make it one of the best building decoration materials.

1.3 Tailings, slag, construction waste
These originally existed as industrial waste, but after a new understanding of them, they are also a "treasure".

For example, crush concrete blocks, crushed stones, bricks and tiles in construction waste to make sand and gravel aggregates, which are used in construction, highways and other industries. Using them as raw materials to produce machine-made sand can save raw material investment costs.

In general, the following points should be paid attention to when choosing raw materials for machine-made sand:
1. The compressive strength of the raw materials used to produce machine-made sand should not be lower than 80 MPa. The materials should not be acidic or alkaline, and clean and hard raw materials should be used.

2. In terms of mine selection, avoid using mines with relatively poor quality such as thick covering soil, more mud in the interlayer, and rocks that are layered into flakes.

3. Select raw materials with exposed rock formations. If they are covered with soil or contain weathered layers, they should be removed in time.

2. Machine-made sand production line (river pebbles)
Since the river pebble itself is relatively hard, I will introduce two production processes according to the production capacity:

2.1 More than 200 tons per hour
Configuration equipment: vibrating feeder, jaw crusher, cone crusher, impact sand making machine, sand washing machine, vibrating screen, conveyor belt, etc.

For hard materials, "jaw crushing + cone crushing" is one of the high-efficiency combinations. The reason why the impact crusher is equipped is that the aggregate needle-like content after the cone crushing treatment is more, and the particle size of the material can be reduced after the impact crushing treatment. Uniformity, good crushing effect, in addition to cleaning and removing impurities by the sand washing machine, the finished product is clean and the market is better.

2.2 The output is less than 200 tons per hour
Configured equipment: feeder, jaw crusher, compound crusher (roller crusher, double-stage crusher), vibrating screen, conveyor belt.

There is no doubt that the jaw crusher is the primary crusher, and all materials within 1200mm can be crushed, and the jaw crusher can process a wide range of materials, and the general ore and rock can be crushed, and the output can be between 1 and 2200 tons per hour. Users can choose Choose according to the actual process.

Compound crushers, double-stage crushers, and double-roller crushers are all small-scale crushing and sand-making equipment. The output design is relatively small, generally below 100t/h, with low power, energy saving, and small space occupation. It is suitable for small stone factory.

Please I have a land in the outskirt of Abuja with a large amount of stone deposit. Where can I rent a mini mobile jaw crusher in Abuja.
