Sudden Shutdown of a Powder Production Line? Follow These Four Steps to Find the Problem in Ten Minutes

When a powder production line suddenly stops, the whole line is waiting. All the pressure is on the maintenance staff. At this time, the worst thing is to take things apart here and there without a plan. Follow the four steps below, so you can find the problem area within ten minutes.

Step 1: Check the Alarm Code
Every modern equipment has a PLC control system. When it stops, the screen shows an alarm code or fault message. First, look at the code. Is it overload, overpressure, high material levelor a sensor disconnection? Wherever the alarm code points, check there first. Do not skip this step and go straight to disassembling the equipment. The alarm code is the most direct clue.

Step 2: Check the Air Supply and Power Supply
After reading the alarm code, check whether the main compressed air valve is open. Check whether the pressure is normal. Check whether the power supply is normal and whether there has been a trip. Air and power are the energy sources for the whole line. If the main valve was closed by mistake or the air compressor tripped, all equipment will alarm. Many "whole-line shutdowns" are actually just air supply or power supply problems.

Step 3: Isolate by Section
If the airand power supply are normal, and the alarm points to only one machine, isolate that machine from the production line. Check it separately. For a conveying line, check whether the upstream feeding is normal and whether the downstream receiving is clear. The purpose of isolation is to narrow the troubleshooting scope. Lock the problem down to the smallest unit.

Step 4: Work from Outside to Inside
After locking down the machine, troubleshoot from outside to inside. First check whether the pipe is blocked. Check whether the valve is stuck. Check whether the seal is leaking. Then open the machine to check internal parts. In many cases, the problem can be found on the outside. You do not need to disassemble down to the core components. Working from outside to inside avoids unnecessary disassembly and secondary damage.

After these four steps, most shutdown problems can be traced to their cause. The rest is targeted repair. Remember one principle: check the alarm first, then check the power sources, then isolate, and finally disassemble and inspect. Doing them in the wrong order will waste a lot of time.
