Product Description

Company Profile
Yurui (Shandong) Machinery Co., Ltd, is an enterprise integrating gypsum projects R&D, design, manufacturing, exportation, installation, and commissioning. We devote ourselves to helping customers quickly achieve projects establish and qualified finished products produced with our superior experience and strength in design, manufacturing, installation& commissioning.

We devote ourselves to helping customers save raw materials, and energy, and reduce the cost of production and equipment maintenance in long term with the most advanced gypsum equipment technology and the most mature gypsum production formula.
We have been deeply engaged in the field since 1994, setting up 100+gypsum projects domestically and abroad. Our engineers' group who only serve for YURUI left a full footprint over Africa, Asia, and South America, more than 20+countries. We hold different projects in each area, offering case visits on-site. Besides we developed online visiting which breaks the limit of the virus.
Technology Advantage
1. The heat supply of the entire production line uses only one heat exchange, which reduces heat loss during multiple heat transfers. It is heated by the flue gas of the hot blast stove through the heat exchanger to the temperature required for production, and then the clean gypsum board is dried by clean hot air. In the process of drying, the hot air can be fully contacted with all sides of the gypsum board drying, so that the problem of dryness of the gypsum board can be better ensured by the problem of low heat on one side and low heat on one side.
2. The whole process of drying is designed by using the hot air circulation method. The fully enclosed system is used in the dryer to ensure that the heat loss during the heat transfer process is minimized, thereby reducing the energy consumption requirement. During the drying process, the entire drying chamber is divided into several zones. We adjust the temperature and flow of the hot air according to the temperature required by each zone, which can save energy.
3. The heating time is short. Only when the hot blast stove is completely burned can the temperature required for the production process be quickly reached.
4. The equipment is easy to operate and easy to control.
5. At present, more than 20 million gypsum board production lines in China use hot air dryers to dry gypsum boards.

Main equipment introduction
Dosing System
Accurate dosing for each raw material. Starch mixing tanks use stainless steel, with long service life and low corrosive. The foaming agent reserve tank is made of stainless steel. The foaming system adopts domestic advanced technology-Dynamic and static foaming system, ensuring the finished board is lightweight, has good toughness, and saves much cost.
Forming System
gypsum slurry from the vertical mixer falls onto the forming line lower paper, the upper paper by the correcting device, glue device sent to the forming station, through the vibration table, the lower paper folding cover upper paper and squeezes out plasterboard of requested specification.
Solidification System

Finished the initial solidification on the belt, and final solidification on conveying roller.
Automatic Cutting System

With the adoption of developed core servo cutting technology of our company, adjusting the required plate dimension by a digital controller. only1 mm gap between cutting saw, Maximally reducing cost by controlling the minimum edge horn size.
Transit System

Used to horizontally transport the cut plate to the distributor, the adoption of servo motor control ensures the precision of the board movement position.

Drying System

The board enters the drying room through a distributor, Drying room is divided into 2 areas: the heating area and the cooling board area, After the drying machine- finished the drying task, the outboard machine discharges the board.

Discharging Board And Finished Board System

Used to convey gypsum board, and cutting to get the required size, then edging and stacking.
Finished Board

1. Newly developed technology, curved edge gypsum boards
2. New developed foamed gypsum board is more lightweight, so easy for installation , also strenght is higher
