Jet Mill

Jet mills use high-velocity compressed gas to drive particle-to-particle grinding. Fluidized bed jet mills can incorporate a dynamic classifier wheel to control product size. The diagrams below illustrate the relative positions of nozzles, classification and collection parts; order against the actual model and assembly drawing.

Individual and Maintenance Parts

Individual and Maintenance Parts

01

Grinding Nozzle

Technical Requirements
YG8: approximately HRA 89+; nozzle bores require precision grinding and control of concentricity, surface finish and flow consistency.
02

Nozzle liner / insert sleeve

Technical Requirements
Al₂O₃: approximately HV 1,000-1,600; SiC can reach approximately HV 2,000+, depending on grade.
03

Classifier Wheel

Technical Requirements
Ceramic wheels require crack inspection and weight control; metal wheels require dynamic balancing to G2.5 or a stricter specified grade.
04

Classifier Blade

Technical Requirements
Consider ceramics for high-purity powders. Control weight variation, angle and surface finish across each blade set.
05

Grinding Chamber Liner

Technical Requirements
Al₂O₃: approximately HV 1,000-1,600, depending on grade. Liner joints should be smooth and prevent material retention.
06

Feed Injector Liner

Technical Requirements
Consider ceramics or cemented carbide in erosion zones. Injection passage dimensions directly affect feed stability.
07

Fluidizing plate / gas distributor plate

Technical Requirements
Solution-annealed 316L is generally no harder than approximately 220 HBW. Control hole diameter, open area and pressure-drop uniformity.
08

Cyclone Separator Liner

Technical Requirements
Ceramics: approximately HV 1,000-2,000+, depending on grade. Check liner joints and bond integrity in the cone section.
09

Discharge Valve Liner

Technical Requirements
Cr26: approximately 58-64 HRC, depending on heat treatment. Consider ceramics or 316L where contamination must be minimized.
10

Seal ring / gasket

Technical Requirements
FKM: a typical candidate hardness is 75±5 Shore A. Select the compound for temperature, solvents and CIP/SIP cleaning media.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, OEM drawing number and measured dimensions before ordering or manufacture.
