Product-temperature window
State the feed temperature, maximum acceptable condition, exposure concern and what quality change signals thermal damage or instability.
Wet-grinding heat path / RFQ brief
Define bead-mill cooling from the product temperature window.
Wet grinding can add heat while product rheology, flow and cooling conditions change through the run. State the allowed product condition and plant utility boundary before discussing a cooling arrangement.
01 / ProductInlet condition, heat sensitivity and viscosity evolution
02 / UtilityCoolant supply, return, stability and site boundary
03 / EvidenceTemperature history, sample result and reviewed duty
Define the complete heat path
Three boundaries make the cooling discussion testable.
A jacket or cooling-water connection does not prove control of the real product. Tie the material limit, heat-transfer path and plant utility together.
Process heat behavior
Record formulation, solids, rheology, media, mill configuration, pass history, batch quantity and operating pattern for the trial.
Coolant and monitoring boundary
Define supply and return conditions, flow stability, ambient environment, measurement locations, alarms and who supplies each utility component.
Thermal review route
Follow temperature from feed tank through the accepted sample.
The same measurement points and sampling basis should be used when candidate operating modes or mill configurations are compared.
01→
Set the material limit
Document the temperature window and the product property that must remain acceptable.
02→
Map the operating cycle
Describe feed preparation, start-up, pass or loop history, pauses, sampling and shutdown.
03→
Define the utility interface
Record available coolant conditions, stability, piping boundary, controls and ambient constraints.
04
Verify under representative load
Review the measured temperature history and product result with the equipment and utility suppliers.
Cooling RFQ checklist
Brief the product, heat path and cooling-water boundary together.
Do not copy another mill’s cooling number into the project. Final selection requires representative testing or a reviewed heat balance using the intended formulation and process.

Buyer decision FAQ
Temperature control is a product condition—not an accessory label.
Why should inlet and outlet temperature be recorded?
They help describe the product’s thermal path through the candidate process. Their meaning still depends on sensor location, operating mode, flow behavior, sampling time and the rest of the documented trial.
Is a cooled grinding chamber enough to guarantee product temperature?
No. Product condition also depends on formulation, feed temperature, rheology, media, mill geometry, operating cycle, coolant conditions and ambient environment.
What cooling-water information belongs in the RFQ?
State the available supply and return conditions, expected stability, flow boundary, water-quality constraints, plant piping and controls responsibility, and ambient conditions.
How is the final cooling arrangement confirmed?
Use representative product testing or a reviewed heat balance that preserves the intended formulation, feed state, operating mode and duty cycle, then obtain supplier confirmation.
