Nowadays, how to improve the output of cement factory has bothered many cement producers, and experts answer this question from different perspectives. As a professional supplier of cement equipment, Zenith has gathered rich experience on the optimization of cement factory. The below is our answer to the question that how cement producers improve the output. And our experts answer that question mainly from the perspective of the optimization of cement grinding plant.
Current Problems of Global Cement Production
The current global consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 KWh/ tonne, and around 40% of this energy is consumed for clinker grinding.
There is potential to optimize conventional method of cement production and in the last decade significant process has been achieved. The increasing demand for “finer cement” products, and the need for reduction in energy consumption and green-house emissions, reinforces the need for the optimization of cement grinding plants.
Current Types of Cement Grinding Plants
As to the optimization of cement grinding plants, we have to find the current types of cement grinding plants. Nowadays, common cement grinding plants include the ball mill, vertical cement mill, Trapezium mill and roller mill, etc. Each of the cement grinding plant has its advantages and disadvantages, so cement producers should make the most of their advantages and keep clear of the disadvantages, which is also the important principle of the optimization of cement grinding plants.
Optimization of Cement Grinding Plants
Grinding occurs at the beginning and the end of the cement making process, including grinding the raw materials of cement and the cement clinker. Approximately 1.5 tonnes of raw materials are required to produce 1 tonne of finished cement.
The electrical energy consumed in the cement making process is in order of 110 kWh/tonne, and about 30% of which is used for the preparation of raw materials and about 40% for the final cement production by the cement clinker grinding production costs and environmental concerns are emphasizing the need to use less energy and therefore the development of energy efficient machines for grinding and classification.
Practice has proved that the optimization of cement grinding plants is closed related with the crushing efficiency. So the selection of crusher can make a difference to the efficiency of cement grinding plants. Typically, a high-efficiency crusher can ease the burden of cement grinding plants.
The more efficiency the crusher has, the higher efficiency the cement grinding plants will have. So the secret of the optimization of cement grinding plants lies in using high-efficiency crushers.
