Cement production line is a cement equipment production line composed of a series of cement production equipment.It is mainly composed of crushing and pre-homogenization, raw material preparation homogenization, preheating decomposition, cement clinker firing, cement powder packaging and other processes.


Cement production equipment can be divided into dry cement production line (including semi-dry process) and wet cement production line (including semi-wet process) depending on the raw material preparation method.


In the process of cement production line, each producing one ton of Portland cement grinding at least 3 tons of materials (including all kinds of raw materials, fuel, clinker, gypsum, mixture), according to the statistics, dry process cement production line of grinding operation need to consume power accounted for about 60% of the entire factory power above, of which more than 30% of raw material grinding, grinding coal accounts for about 3%, accounted for about 40% of cement grinding.Therefore, reasonable selection of grinding equipment and process flow, optimization of process parameters, correct operation, control operation system, to ensure product quality, reduce energy consumption has great significance.


In cement production pipeline, the use of valves in the entire production process plays a very important role, in the right place to reasonable use of valves, to ensure the smooth work of the entire cement production pipeline.


In the whole production process, in order to ensure that raw materials, fuels, materials and raw materials, clinker, cement meet the requirements, each step of the production process must carry out production control and quality control.As a supplier of high quality valves, Bundor valve provides you with a complete set of valve solutions for cement production pipelines.

Use Of Valve In Cement Plant

1. Raw material preparation: Raw material preparation is the preliminary step of cement production. Its main task is to crush the limestone and send it to the grinding head feeding silo with clay and other auxiliary materials through the conveyor.The main valves used in this link are high temperature air valve, hundred leaf air valve, Soft rubber joint, etc.

2. Clinker calcining: Clinker calcining is a key step in cement production, including five steps of preheating outside the kiln -- decomposition -- calcining -- cooling -- waste gas treatment.The main valves used in this stage are wear-resisting butterfly valve, knife gate valve, check valve and so on.

3. made of cement, cement grinding is the end of cement manufacturing process, is also more power consumption process.Its main function is to grind the cement clinker to the appropriate particle size, form a certain particle size distribution, increase its hydration area, accelerate hydration speed, and meet the requirements of cement slurry setting and hardening.The main valves used in this stage are knife gate valve, butterfly valve and so on.
