Introduction to cement clinker

Cement clinker

Cement clinker is the semi-finished products based on limestone and clay, iron raw materials as the main raw material, formulated into raw materials according to the appropriate ratio, burning until part or all of the molten, and obtained after cooling. In cement industry, the principal chemical components of the most commonly used Portland cement clinker are calcium oxide, silica and small amounts of alumina and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate and iron aluminate tetracallic acid, Portland cement clinker plus appropriate amount of gypsum after grinding can be made into portland cement.

Application of cement clinker

At present, cement clinker is widely used in civil and industrial construction projects, such as cementing of oilfields and gas fields, large-volume dams in water conservancy projects, military repair projects, as well as acid and refractory materials, injection in tunnels cap instead of pit. In addition, wood and steel can be used instead of wood for a variety of applications such as telephone poles, railroad sleepers, oil and gas pipelines, and oil storage and gas storage tanks.

Analysis on grinding mill models

Vertical roller mill:

Large scale equipment and high output can meet large-scale production. This Cement Clinker Mill has high stability. Disadvantages: high equipment investment cost.

Stage I: Crushing of raw materials

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

Stage II: Grinding

The crushed cement clinker small materials 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.

Stage III: Classifying

The milled materials are graded by the grading system, and the unqualified powder is graded by the classifier and returned to the main machine for re grinding.

Stage V: Collection of finished products

The powder conforming to the fineness flows through the pipeline with the gas and enters the dust collector for separation and collection. The collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then packaged by the powder tanker or automatic packer.

Application examples of cement clinker powder processing

Guilin Hongcheng cement clinker grinding machine is durable and the equipment and products are excellent. Among them, the concept of environmental protection is very prominent. The dust overflow in the pulverizing workshop is basically very small, the overall environment is clean and tidy, and the power consumption is also very low. This is very important for production enterprises, which directly reduces production and operation costs and saves a lot of expenses for pulverizing enterprises. Therefore, this is a mill with excellent performance.
