Calcium carbonate is one of the most useful and versatile materials known to man, and it is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. In the modern industry, calcium carbonate has a wide application, for example, calcium carbonate is the active ingredient in agricultural lime. Here we focus on one of project case in Pakistan, taking the calcium carbonate crushing unit for example.

Design From SBM's Mining Engineers

In the mining industry, typical crushing unit used for processing calcium carbonate include crushers, ball mills and air classifier powder concentrator and other associated machines. After making a careful analysis of local mineral, engineers from Zentih found that the humidity and rigidity are higher. Therefore, it needs a drying machine to reduce the moisture. In the crushing unit, crusher is used for making large rocks into smaller particles. Usually, PE Series jaw crusher is widely used for crushing calcium carbonate rocks. After the crushing stage, grinding machine will be needed to make calcium carbonate powder. To meet the requirement from our customer, engineers from SBM suggest our ultrafine mill, which is specially designed for the grinding size of powder ranging from 8 micron to 400 micron. In addition, it is a complete plant, including the bucket elevator, hopper, vibrating feeder, classifier, pulse bag filter, cyclone collector, pipes and all necessary parts, our small ultrafine mill can reach the capacity about 2-4 t/h in line with the output size of 8 micron. Under the professional guidance of our engineers, they have finished the installation and commissioning successfully.

Outcome of Project

SBM has designed the complete calcium carbonate crushing unit which satisfy the demand for capacity. Now the complete crushing unit is running well. Several days ago, our customer told us they would like to expand their production scale. And they still have a great interest in our machines.
