3.dust collector
4.elevator

Gypsum powder production line (natural gypsum) uses advanced processing equipment such as a vertical mill, boiling furnace, etc. The boiling furnace is the most widely used gypsum calcining equipment in China, and is applied to calcining process of natural gypsum and chemical gypsum. Our boiling furnace has the advantages of compact size, simple structure, high productivity, low energy consumption, stable physical performance, ease of operation and low operating cost. Today, our gypsum powder production line is well received in Thailand, Uzbekistan, Colombia, Mexico, among others.
Through our years of experience and the consistent efforts of our dedicated staff, we can produce gypsum powder production line with output ranging from 3 tons/h to100tons/h. In addition, we can also customize our production line according to customers' specific requirements. To ensure our customers are satisfied with their purchase, we offer them complete services, including project design, equipment manufacturing, installation, debugging, staff training, etc.

2. Process and Equipment

2.1 Equipment Introduction
2.1.1 Crushing, Grinding Section
2.1.2 Calcining Section
2.1.3 Finished Product Packing and Storing Section
2.2 Electronic Control System
2.2.4 Main Production Control
2.2.4.1 Design Principles and Programs
In order to meet the process requirement of modern gypsum powder production line, ensure reliable operation of processing equipment and product quality, conserve energy and improve operating rate of our production line, our project uses the technically advanced distributed control system (DCS) to realize centralized monitoring, operation and decentralized control of the production line, which greatly improves the reliability and maintainability of the electrical control equipment. Nowadays, the factory management information system (MIS) can be easily connected to the DCS system, which can help the administrator to know the actual situation of factory production timely.
2.2.4.2 DCS system overview
Our gypsum powder production line is equipped with an independent DCS system, whose main functions are:
1). With process flow diagram which displays dynamic process equipment status and process parameters;
2). Process equipment group, stand-alone start and stop operation panel and equipment operating status display;
3). Group show of process parameter operation panel and process parameters;
4). Timely process parameter and history trend curve display;
5). Detailed display of regulating loop and parameter adjustment;
6). Process state alarm display;
7). Alarm report and process parameter report printing;
8). When production line gives an alarm, it will show and record the related parameters and display alarm handling tips to facilitate timely troubleshooting;
9). Control system status display
2.2.4.3 Application Software
2.2.4.3.1 Logic Control Software Functions
2.2.4.3.2 Process Control Software Functions
2.3.1 Crusher
Ratio of reduction: feed: less than 350mm, material discharged: 20mm, output: 13 tons per hour
2.3.2 Hoist
Our hoist uses the advanced NE chain elevator, which features great transport capacity, low energy consumption, smooth running etc.
2.3.3 Mill
To ensure the reliability and quality of our mill, we utilize Raymond mill as our grinding equipment, which has the following advantages:
1). It is of vertical type structure, occupies small area, and can perform all functions from rough processing of raw material, conveying, milling to final packaging;
2). 99% gypsum powder can pass through the screen;
3). The drive unit adopts closed gearbox and belt pulley for reliable operation;
4). Key components of the mill are made from superior castings and section bar, thus ensuring the durability of the equipment;
5). The electrical system of the mill adopts centralized control, highly automated;
2.3.4 Calciner
Our gypsum calciner is compact, energy efficient, easy to operate and simple to maintain.
2.3.5 Electrical Control Cabinet
In order to ensure the smooth running of the system and reduced downtime, we use famous brand electrical components, including Mitsubishi or Siemens PLC and inverter, Schneider low-voltage electrical parts, Chint cabinet body, etc.
