Many units are overloaded. Cement is often calcluated to have a volume weight of 1,5 ton per m3 material. Many work with a vacuum truck on a hose only basis. This is very costly and inefficient as hoses has to be dragged through the plant to where the matrial is located with a high external and internal wear as a result.
Regardless of the specific purpose of a feed plant, material flow follows a basic pattern (see Figure 1). 2. RECEIVING. The first operation in the feed processing plant involves the receiving of raw materials into the plant premises. Feed ingredients arrive in sacks, or other small containers, and in bulk.

Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
and flow of the various materials through these plants are different. The asphalt mixtures produced, however, should be identical, regardless of the type of plant used to manufacture it. A brief review is provided below of the flow of materials and operation of batch plants, continuous mix plants, and drum mix plants.
Aug 30, 2012· Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.
Use of alternative fuels and byproducts materials. A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.

Drake Cement is the newest cement company in the Southwest, with operations beginning at the Arizona plant in 2011. The firm specializes in high quality Portland cement products for the North American market, while improving the local availability of a critical building material.
In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.
