Clinker Uses And Grinding Processing Solution2021-07-28

What Is Clinker

Cement clinker is a semi-finished product obtained by mixing limestone, clay, and iron raw materials as raw materials in an appropriate proportion, burning to partial or full melting, and cooling. In the cement industry, the main chemical components of the commonly used Portland cement clinker are calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminate aluminate. Portland cement clinker can be made into Portland cement after grinding together with appropriate amount of gypsum.

Uses Of Clinker

At present, cement clinker is widely used in civil and industrial construction engineering fields, such as cementing in oil and gas fields, large-volume dams in water conservancy projects, and military repair projects. It can also be used as acid-resistant and refractory materials, and injection in tunnels. Capped to replace pit wood. In addition, it can also replace wood and steel for many occasions, such as telephone poles, railway sleepers, oil and gas pipelines, crude oil storage and gas storage tanks.

Clinker Powder Production Process

Raw material analysis report:

CaO SiO2 Fe2O3 Al2O3
62%-67% 20%-24% 2.5%-6.0% 4%-7%

Mill recommendation

Powder fineness 220-260/kg(R0.08≤15%)
Mill recommendation  LM series vertical roller mill

Remarks: Choose different types of hosts according to the output and fineness requirements.

The First Stage: The Crushing Of Raw Materials

The cement clinker material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

The Second Stage: Milling

The crushed small pieces of cement clinker are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding.

The Third Stage: Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

The Fourth Stage: The Collection Of Finished Products

The powder that meets the fineness is separated and collected in the dust collector through the pipeline through the airflow. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged by a powder tanker or an automatic baler.
