Process parameters
(1)Clinker output: ≥ 1500 t / d;
(2) heat consumption: ≥ 840kcal / kg clinker
(3) power consumption: ≥ 110kwh / t cement
(4) water consumption: maximum 1020m3/d
Production process
In cement production, limestone and clay are used as main raw materials, which are crushed, proportioned and milled into raw materials by ball mill, then fed into cement rotary kiln to calcine mature materials, and the clinker is added with a proper amount of gypsum, mixed with some mixed materials or additives, ground into cement by cement grinding, after that transported out of the factory by packaging machine or bulk machine. Cement production equipment usually adopts the dry cement production process. The main advantage of dry production is low heat consumption.
