Our cement mill is widely used in many sectors, such as black metal, nonferrous metal mining sections, non-metal mines, construction, electricity, coal, traffic, light industry and so on.  energy saving ball mill produced by our company adopts rolling bearing support.  Comparing with other software, can store save energy by 10-20%.  So if the same power output capacity will increase by 10-20%.

Raw

The main raw materials used in the production of cement is limestone, sand, shale, clay and iron ore.  The main area limestone, is usually picked up at the hotel, while the smaller materials can be obtained on site or nearby quarry.  Another source of raw materials, industrial by-products.  The use of materials for the product to replace natural raw materials is a key element in achieving sustainable development.

Preparation of raw materials

extraction of limestone, requires the use of techniques for drilling and blasting.  blasting techniques with the latest technology for vibration, dust and noise are minimized.  Blasting produces materials in a variety of sizes of about 1.5 meters in diameter for small particles less than a few millimeters in diameter.

The material is added to the explosion in front of trucks for transport to the crushing plant.  Through a series of crushers and screens, limestone is reduced to less than 100 mm and stored until needed.

Depending on size, materials, but less (such as sand, shale, clay and iron ore) or can not be crushed before they are stored in separate areas until needed.

raw mill

In the wet process, each raw material provided to meet a desired chemical composition is fed to a rotating ball mill with water.  The raw materials are crushed to a size where most of the materials that are less than 75 microns.  leaving the plant materials are called “mixed” and flow.  This mixture is pumped to mixing tanks and homogenized for the chemical composition of the mixture is correct.  After the homogenization process, the mixture stored in tanks before use.

In the dry process, each raw material supplied in response to a given chemical composition and received either a rotating ball mill or vertical roller mill.  Raw materials are dried with waste gas treatment and soil of a size that most materials that are less than 75 microns.  The output of dry any type of construction called “feed the stove.”  The oven air mixed for the chemical composition of kiln feed is well mixed and stored in silos until needed.
