Sand and stone quarries are a highly profitable industry.
The annual profit of a quarry can be no less than 5 million yuan.
From setting up an aggregate production line to carrying out rock crushing,
investigations show that the total investment cost of an aggregate production line is less than one million yuan.
It is a project with low investment and high return, economical and cost-effective.
So what machinery is required to set up an aggregate production line?
The corresponding solutions are as follows.
The typical process flow of an aggregate production line is:
(Stockpile) → Vibrating Feeder → Jaw Crusher → Impact Crusher → Vibrating Screen → (Finished Products)
Conveyors are used to connect the machines.
1. Crushing Equipment
Mainly including jaw crusher, cone crusher, impact crusher, etc.
These machines crush raw materials into aggregates before sand making.
The particle size is controlled to meet the requirements of the next process.
Materials that do not meet the size standard will be returned for re-crushing.
2. Shaping Equipment
Such as shaping crusher.
Crushed materials are fed back into the shaping crusher for further fine crushing and shaping.
They will not enter the sand maker until they meet the required particle size.
A circular vibrating screen is used for classification:
qualified materials go to the sand maker,
while unqualified ones return to the shaping crusher again.
3. Sand Making Equipment
The sand making machine is critical, as it determines the quality of the final product.
Our technical manager recommends sand makers with two crushing modes,
so that different crushing principles can be adopted according to the material’s hardness, size and density.
This ensures more uniform products, avoiding over-crushing or oversized particles.
4. Sand Washing Equipment
Usually a sand washer is adopted.
The finished sand from the sand maker is evenly fed into the sand washer for cleaning.
Clean sand and aggregates can be directly transported and used in various construction projects.
