High-efficiency Cement Plant
The cement manufacturing process aims to build a cement production line from raw materials crushing to cement packing and delivery. The proposal is made for new dry cement manufacturing process line with suspension cyclone preheated. Most of the major equipment used in the production line is manufactured in China in recent years based on the licenses from the Western countries, e.g. Some of key equipment will, if necessary, be supplied by the Western countries,
We have expertise in handling the demands of cement machines. Our experts can help you to produce more cement, at lower costs, with less environmental impact.
We have experts in cement making machine, pioneers in emissions controls, and decades of experience in plant design for either new greenfield sites or existing brown field modernizations.
What’s more, we produce full sets of mining machinery that consists of feeders, bucket elevator, screw & belt conveyors, etc.
Cement Production Line Flow
1. The cement manufacturing process begins when limestone, the basic raw material used to make cement, is transported by rail to the Edmonton plant from the Cadomin limestone quarry 220 kilometres west of Edmonton.
2. The limestone is combined with clay, ground in a crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.
3. Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 metres in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.
4. The clinker is combined with small amounts of gypsum and limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tons of steel balls that is driven by a 4000 hp motor.
