Complete solution for limestone powder production โ from raw material crushing to finished powder. Output fineness: 200 to 2500 mesh. Capacity: 1 to 100 TPH.
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCOโ), typically >90% purity in industrial grades. Its physical properties make it ideal for grinding into fine powders used across multiple industries.
A full production line typically consists of these four stages. Each stage uses specific equipment matched to your capacity and fineness requirements.
Raw limestone blocks (โค1000mm) are fed into a jaw crusher or impact crusher, reducing particle size to โค30mm. This prepares the material for efficient grinding.
Crushed limestone is fed into the grinding mill. Depending on your target fineness (200โ2500 mesh), we select Raymond Mill, Vertical Mill, or SCM Ultrafine Mill.
A high-efficiency classifier (integrated into the mill or standalone) separates oversized particles, which are returned to the mill for re-grinding. Ensures consistent fineness.
Qualified powder passes through a pulse dust collector, collecting 99.9% of particles. Final product is conveyed to storage silos or directly to bagging machines.
We can produce limestone powder from coarse 200 mesh all the way to ultrafine 2500 mesh. Each fineness grade serves different industrial purposes.
Agriculture, roadbase, soil treatment. Low-cost application, high volume.
FGD desulfurization, cement admixture. Most demanded specification.
Paper coating, PVC filler, adhesives. Higher value product.
Premium calcium carbonate, rubber, high-grade plastics filler.
