Description
Technical field
The present invention relates to a kind of cement producing line, belong to construction material production technical field.
Background technology
Cement producing line is the cement equipment production line of a series of equipment composition producing cement.Mainly by crushing and the process such as homogenizing, raw material preparation homogenizing, pre-thermal decomposition, the burning till of clinker, cement grinding packaging is constituted in advance.
Portland-type cement production technology is representative in cement manufacture plant, it is with lime stone and clay as primary raw material, through broken, dispensing, levigate make raw material, then mature calcined material in feeding cement kiln, then grog is added proper amount of gypsum (the most also admixture mixing material or additive) levigate form.
Cement manufacture plant is different with method for preparing raw material, can be divided into dry cement production line (including semidry method) and wet-process cement production line (including half wet process) two kinds.
1. the cement produced with the dry method technological process of production.Raw material is dried and grinding simultaneously, or first dry after grinding becomes raw meal powder, feed the method for mature calcined material in dry method kiln.But also have and raw meal powder is added suitable quantity of water make raw material ball, send into the method for mature calcined material, referred to as semidry method in lepol kiln, still belong to the one of dry production.The major advantage of dry production be heat consumption low (as with the dry method kiln heat consumption of clinker of preheater be 3140～3768 burnt/kilogram), shortcoming is that raw ingredients is difficult to uniformly, and greatly, power consumption is higher for workshop airborne dust.
2. the wet-process cement technological process of production.After the grinding that added water by raw material becomes raw slurry, the method for feeding wet-process rotary kiln mature calcined material.Also, after having raw slurry dehydration wet method prepared, make the method that raw material block enters kiln mature calcined material, referred to as half wet process, still belong to the one of wet production.The advantages such as wet production has simple to operate, and raw ingredients is easily controlled, good product quality, and slurry pipeline transport is convenient, and workshop airborne dust is few, shortcoming is heat consumption high (heat consumption of clinker be usually 5234～6490 burnt/kilogram).
During cement producing line, often produce 1 ton of portland cement and at least want 3 tons of materials of grinding (including various raw material, fuel, grog, compound, gypsum), according to statistics, dry cement production line grinding operation needs the power consumed to account for more than the 60% of full factory power, wherein raw grinding accounts for more than 30%, coal mill accounts for about 3%, and cement grinding accounts for 40%.
Accordingly, it would be desirable to rationally select milling equipment and technological process, to ensure product quality, to reduce energy consumption.
Summary of the invention
