2.Process Description

The gypsum rocks with the dimeter less than 300mm are pushed into Chain Conveyor by forklift, then they are sent to Crusher by Chain Conveyor, being crushed into small grain less than 25mm and then being stored and metered by Belt Scale then being sent into Vertical Mill to mill. After being milled, the qualified gypsum powder will be sent to Boiling Kiln to calcine; after being calcined, parts of the temperature of the qulified gypsum powder is 800-100°C after being cooled. Then the gypsum powder is sent to hemi-hydrate gypsum storehouse by air current conveying system.

3. Description of Electric Control System and Auto-control System

3.1 Control system of Gypsum Powder Production Line

We use DCS (Distributed Control System) because that powder control system is a process automatic system with dispersive control point, this system can be divided into 1 main station and 4 sub-station by the different zones, which are respectively in Main Control Room, Crusher, Calcinating, Mill, Boiling Kiln and Storehouse. Every part of this system in Central Control Room and at Site can control all control points and know producing circs, writing down control cics and giving an alarm. Gypsum Powder production line is a continuous process, if one part is in trouble, it will stop the whole line, so it is very important to find out malfunction in time.

3.2 Electric structure drawing

Control ways: There are 3 ways for the electric control system: CRT Automatic, CRT Manual & Site Control.

CRT Automatic: the site will operate according to the procedure requirements when the control condition for operation and process equipments all meet requirements, making orders by central control room.

CRT Manual: the workers operate process equirements separately and manually by the requiements of process, making orders by central control room. ( such as adjusting flux of Belt Scale, adjusting temperatures, etc.)

Site Control: to operate equipments on site.

3.3 Electric control equipments

3.3.1The general design is in conformity with GB Standard and IEC Standard.

3.3.2The control cabinet adopts NSM cabinet of CHNT, protection-resistance grade for cabinet body is IP55.

3.3.3Power pressure degree

Dynamical power supply:Three phase 380V AC 50Hz

Control power supply: Two phase 220V AC 50Hz

PLC I/O power supply: 24V DC

Transducer power pressure:24V DC

Please point it out if the power supply in the Buyer’s site does not meet the above requirements. The Seller shall consider differences in the design and equipment selection avoid equipment failure or inability to produce
