Engineered for paper mills
Paper Machine Release Agent Spray System
Precise, repeatable release agent application for cleaner running surfaces, fewer process interruptions, and better control of chemical use.
Replace inconsistent application with an engineered spray process
Sticky deposits on dryer cylinders and fabrics can contribute to sheet breaks, cleaning stops, unstable production, and premature doctor-blade wear. Manual or fixed-point spraying often makes the problem harder to control because chemical flow, droplet size, application width, and timing vary from shift to shift.
The Baozt paper machine release agent spray system combines accurate liquid metering, compressed-air atomization, a traversing spray mechanism, and PLC control. It applies a fine, controlled spray across the selected process area and can stop automatically when machine conditions require it. Each installation is engineered around the paper machine rather than treated as a standard off-the-shelf package.
How the system works
- Metering: an electromagnetic metering pump supplies a repeatable liquid flow.
- Secondary atomization: the patented nozzle mixes liquid and air internally to create a fine spray pattern.
- Controlled traverse: the nozzle moves across the configured range instead of concentrating chemical at one point.
- Automatic interlocking: PLC logic coordinates the drive and metering pump with machine operating signals.
- Protective film: release agent is distributed across the target surface to help reduce adhesion and deposit buildup.
System configuration
| Module | Function | Engineering considerations |
|---|---|---|
| Spray beam and body | Protects and guides the traversing mechanism | 304 stainless steel construction; mounting and access designed from site dimensions |
| Atomizing nozzle | Produces a fine, directed release-agent spray | One, two, or three nozzles; direction and pattern selected for the application |
| Metering station | Controls liquid flow and pressure | Chemical properties, target dosage, calibration, and operator access |
| Air circuit | Supplies atomizing energy | Available mill pressure, filtration, stability, and connection point |
| PLC control cabinet | Controls travel, pump, alarms, and interlocks | Local controls, DCS I/O, machine signals, and agreed fail-safe behavior |
| High-temperature tubing | Transfers air and release agent | Routing, heat exposure, corrosion resistance, and maintenance access |
Designed for the paper-machine environment
Heat, humidity, dust, vibration, and limited access make paper-machine installations demanding. Baozt uses a stainless-steel body, protected cable-chain routing, high-temperature tubing rated up to 240 C, and industrial components selected for these conditions. The main assembly can be withdrawn from its support for inspection, helping maintenance teams reach critical parts without rebuilding the installation.
Travel speed and spray range are adjustable. Limit switches define the active area, while the drive provides variable-speed movement. If the controller detects abnormal travel, it can stop the motor and metering pump together to protect the process.
Application engineering before quotation
A useful proposal starts with process facts. Baozt reviews the target surface, contamination pattern, paper grade, machine speed and width, available mounting space, release-agent properties, utility conditions, and automation requirements. Photos, drawings, and a short operating history help the engineering team identify the correct configuration.
Following installation, commissioning establishes flow, air pressure, travel range, speed, and interlock behavior. Performance should then be evaluated against an agreed baseline rather than a single visual observation.
Frequently asked questions
What does a paper machine release agent spray system do?
It meters and atomizes release agent across a controlled section of a dryer cylinder or fabric. The resulting film helps control adhesive deposits, supports cleaner running surfaces, and reduces manual application variability.
Can the system connect to a mill DCS?
Yes. The PLC control architecture supports remote start and stop, status monitoring, and interlocks with machine stop or sheet-break signals. The final I/O list is confirmed during engineering.
How is spray coverage matched to machine width?
The traversing range, nozzle count, nozzle direction, travel speed, and mounting arrangement are configured from site measurements and process requirements.
Which components are designed for the hot, wet paper-machine environment?
The system uses a stainless-steel body, high-temperature tubing, protected cable-chain routing, industrial limit switches, and components selected for humid production conditions.
