Computer Control of the Whole Equipment of Organic Fertilizer Production Line
2022-09-09
The npk manufacturing process basically includes batching machine, pulverizer, mixer, double roller granulator, dryer, cooler, screening machine, automatic packaging machine, belt conveyor, etc. The computer control of the whole set of equipment of the organic fertilizer production line is programmable through the program controller (PLC). The organic fertilizer processing production line uses programmable memory to perform logical operations, sequence control, timing, counting and arithmetic operations on its internal stored programs. and other user-oriented instructions and control different types of machines or production processes through digital or analog input/output.
Programmable logic controllers have the following characteristics:
1. The whole set of organic fertilizer npk fertilizer production line equipment is easy to use and simple to program: using simple programming languages such as ladder diagram, logic diagram or statement list, the system development cycle is short and on-site debugging is simple. In addition, the program can be modified online to change the control scheme without disassembling the hardware.
2. Powerful and cost-effective: There are hundreds of software elements in the computer for users to use, with powerful functions, which can realize very complex management functions. Compared with the relay system with the same function, it has a higher cost performance. PLC can be networked through communication to realize decentralized control and centralized management.
3. Complete hardware, easy for users to use and strong adaptability: computer and PLC products are standardized, serialized and modularized, and equipped with a complete set of different hardware equipment for users to choose. Users can configure the system flexibly and conveniently to form systems with different functions and scales. PLC installation and wiring are also very convenient. Typically, connection terminals are used to connect external wiring. The PLC has a large load capacity and can directly drive general solenoid valves and small AC contactors. Once the hardware configuration of the organic fertilizer processing production line is determined, the user program can be modified to easily and quickly adapt to changes in process conditions.
