Grinding Station Solution

Solution

At present, grinding stations generally exist following questions . Clinker Grinding Unit presently with high energy consumption and low productivity, and it’s not meet the requirements of national policy . Serious dust pollution and noise.The production line presently with large area occupying and complex production process . The equipment presently is old-fashioned, lower productivity and inferior quality.

During 12th five-year plan, DNRC puts forward higher requirements to cement enterprises that the enterprise with low productivity, high energy consumption and high pollution will be shut down, encourage adopts advanced technology, equipment and large-scale production.

Under the new circumstances, cement industry puts forward new requirements on Clinker Grinding Unit and production lines . Putting national policy into effort, forgoing high energy consumption equipment, using of more energy-saving equipment . Adopting advanced technology and equipment , reducing environmental pollution, and improving production efficiency . Optimizing structure of production line, reducing the costs of production, and improving the profits.

Traditional clinker grinding unit adopts ball mill to grind clinker, and has much dust, loud noise and high energy consumption in the process of production, it will be replaced gradually by vertical roller mill.

The cement clinker grinding plant or the cement grinding station acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then forms the finished cement. There are three procedures of the China cement grinding plant: raw material preparation, clinker burning and cement making.

When we establish the cement clinker grinding plant and the cement production line together near the raw mineral field, we also need to increase the transportation expense because most mixing materials which are waste residue from the city should be first transported to the cement plant to be ground and then be transported to the city again for new use. Therefore, the cement clinker grinding plant is usually set up around the city in order to make the urban area have quick access to the cement.
