Description

Process Flow of ***0Tons/Day Dry Process Cement Plant:
The main process flow of this ***0t/d dry process cement plant is as follows:
1. Crushing, Conveying and Storing of Limestone.
First, limestone is crushed by the MB*6/*5 crusher. When the maximum feeding size is not more than ***0mm and the discharging size is not more than *5mm, the crushing capacity of this machine is **0 to **0t/h.
Second, the crushed limestone will be transported by belt conveyor to the Φ*0m round prehomogenization yard whose storage capacity is ****0t.
Third, the crushed limestone will be prehomogenized and then stored in this yard. Additionally, the stacking capacity of our stacker is **0t/h, and the reclaiming capacity of reclaimer is **0t/h.
Finally, the prehomogenized limestone will be sent to the batching station for raw materials.

2. Storing, Crushing and Conveying of Auxiliary Raw Materials.
The open storage yard for sandstones has a specification of *0 m×*0m, and a storage capacity of ***0t. And the open storage yard for iron ores has a specification of *2 m×*0m, and a storage capacity of ***0 t.

PC***9 hammer crusher is used to crush both sandstones and iron ores. When the feeding size is not more than **0mm, and discharging size less than *5mm, its crushing capacity is *0 to *0t/h.

The crushed sandstones and iron ores will be sent by the belt conveyor to batching warehouse for storage.

The pulverized coal will be stored in the batching warehouse for storage through the self-discharging system.

3. Batching Station for Raw Materials.
In the batching station, there are four batching warehouses respectively for limestone, sandstones, iron ores, and pulverized coal, and their specifications are φ*2 m×*5m, and storage capacity are ***0t,***0t, ***0t, and **0t respectively. Inside these warehouses, there are weighing feeders used to measure materials to be given.

4. Grinding of Raw Materials and Waste Gases Treating.
MLS***6 vertical mill is used to grind raw materials, and waste gases from preheater are applied in drying. The whole production capacity is **5t/h.

Grinded raw meal is separated by the fine powder separator, and then mixed with powder in the conditioning tower and electric environmental protection equipment. Finally it will be sent to the homogenizing warehouse for homogenization as well as storage.

Waste gases from the mill will take purification treatment in the electric environmental protection equipment before discharged into the air.
 

5. Homogenizing of Raw Meal.
Our CP homogenizing silo has a specification of Φ*8m×*0m, and its effective storage capacity is ***0t.

6. Calcining and Storing of Clinker.
The specification of our RF5/***0 decomposition furnace isΦ4.0×*0m, and our round *-φ*8×*0m warehouse has an effective storage capacity of ******0t. Additionally, the final discharging gas has a dust content less than **0mg/m3 if in standard conditions.

7. Storing and Conveying of Raw Coal and Pulverized Coal.
Raw coal will be stored and prehomogenized in a crane room with a specification of *1m×**3m and a storage capacity of ***0t. There are two raw coal silos in the crane room, and weighing feeder can also be found in that room. A MPF***3 coal grinder is used to grind coal. When the moisture of feeding materials is no more than *0%, the moisture of pulverized coal is no more than 1%, and the particle size of raw meal is no more than *0mm, the output of the whole system is *0t/h.

The pulverized coal will be sent to two silos for storage, and the purified waste gas is discharged into the atmosphere. There is also measuring system in these two silos.

8. Drying and Conveying of Slag and Crushing and Conveying of Gypsum.
The drying capacity of ourφ2.4×*8.**0m dryer is more than *0t/h, and the open storage area has a storage capacity of ***0t. When the feeding size is no more than **0mm and the discharging size is no more than *5mm, the productivity of our PFC****9 impact hammer crusher is *0 to *0t/h.

9. Grinding, Conveying and Storing of Cement.
In the cement batching station, there are four batching rooms respectively for clinker, gypsum, limestone and slag. And the clinker one has a specification of φ*0 m×*2m and a storage capacity of ***0t. The specification of batching rooms of gypsum, slag and limestone is φ8 m×*2m, and their storage capacity is **0t, **0t and **0t respectively. The packaging capacity of packing machine is *0t/h.
