How to Produce EPS Cement Sandwich Wall Panel?
There are 6 sections of producing the lightweight EPS cement wall panel:
Section 1: Raw Materials Preparation
Section 2: Raw Materials Mixing
Section 3: Raw Materials Filling
Section 4: Wall Panel Curing
Section 5: Wall Panel Demolding
Section 6: Wall Panel Stacking and Storage
Section 1: Raw Materials Preparation👍
This is the starting section of the wall panel production, including the expandable polystyrene expanding system( to produce the foam EPS particle).
The main equipment of producing the expanded EPS particles are steam boiler,EPS expanding machine,EPS drying machine and finished foam EPS storage silos.
The materials of EPS can be bought from the local market or imported from China or elsewhere. The suitable type of EPS raw materials is the Flame Retardant type,specification can be ZKF-303,this is the suitable EPS beads for making fireproof EPS cement wall panel and other wallboard that require high fireproof rating.
The silos for storage the expanded EPS particles are made of square steel tube and high quality mesh,there will be several storage silos of the wall panel making plant, the quantity of silos depends on the capacity of the wall panel production line. A medium scale wall panel plant has 3-4 EPS silos and a large scale wall panel manufacturing line has 5-10 silos.
Cement,fly ash ( if use fly ash) will be stored in the cement silo and fly ash silo, the silos are made of steel plate. According to different capacity of the wall panel making plant, the volume of cement silos can be from 50 tons, 100 tons, 150 tons and 200 tons.
Sand will be batched by a sand batching machine and delivered to the mixer.
Automatic delivery systems and weighing units are equipped with the plant. Cement,sand,EPS,water and additives will be weighed and delivered automatically under the central control PLC system. We provides one-button operation solution for the high automatic level of EPS cement wall panel manufacturing plant upon required.
Section 2: Raw Materials Mixing👍
After the batching,weighing and delivery,the mixer will start the mixing process. This is the key part and important machine of the wall panel production line,as important as the wall panel making machines. The wall panel slurry mixer has special inside structure. This slurry mixer is developed by our team, especially for light composite wallboard slurry foaming and mixing. Using our designed slurry mixer, the wall panel slurry can achieve excellent mixing and foaming effect.
Section 3: Raw Materials Filling👍
The automatic slurry filling machine is equipped with a special mixing device, which can prevent the wall panel mortar from sinking into the bottom and make the EPS particles completely wrapped by the slurry.The volume of the filling machine depends on the scale of the panel plant,we design and produce the slurry filling machine with volume from 1.5cbm to 5cbm. The mixed slurry is discharged into the tank of the filling machine, the filling machine is mobile type, it will move above the wall panel mold car, and then discharge and fill the slurry into the wall panel mold cars.
Section 4: Wall Panel Curing👍
After the wall panel making machines are filled with slurry,the ferry car will transport the mold cars to the curing line. The period of wall panel curing time is about 4 hours to 6 hours, it also depends on the site conditions,for example,different temperature and different materials formula will effect the time of curing.
Section 5: Wall Panel Demolding👍
After the curing process is completed, the wall panel mold cars are transported to the panel demolding line by the ferry car. The wall panel making machine is equipped with hydraulic system, so the panel mold car can lie down for demolding automatically, and the mold car also can raise up by the hydraulic system after the mold re-setting process is finished.
The wall panel demolding machine has two functions, one is pulling the panels out of the mold car automatically, the other function is stacking the panels,so all the wall panels can be transported by a forklift after the demolding and stacking.
Section 6: Wall Panel Stacking and Storage👍
A large warehouse is required as the storage area for the finished wall panels. After about 2 to 3 weeks period stay in the warehouse,the wall panel will be delivered to the construction sites for different projects application.
