Original JWI J-Mate Sludge Dryer Manual

---

 The JWI J-Mate Series was one of the most widely used continuous sludge dryers installed in industrial wastewater treatment facilities.

Unlike today's batch sludge dryers, the J-Mate utilized a continuous feed design that allowed dewatered sludge from a filter press to be fed directly into the dryer while dried product exited continuously.

Thousands of these systems were installed throughout:

• Metal finishing 
• Electroplating 
• Chemical manufacturing 
• Printed circuit board facilities 
• Industrial wastewater treatment plants 

Although the JWI brand has changed ownership multiple times, many of these dryers continue operating today with proper maintenance.

 During its history, the J-Mate dryer has been associated with several companies, including:

• JWI 
• USFilter 
• Siemens Water Technologies 
• Evoqua Water Technologies 
• Xylem 

Regardless of the nameplate on your machine, many of the mechanical components remain similar.

Met-Chem continues to support owners of these legacy systems with replacement parts, technical assistance, and complete replacement dryers.

 The original factory manual includes information such as:

• Installation procedures 
• Equipment specifications 
• Safety precautions 
• Startup procedures 
• Shutdown procedures 
• Preventive maintenance 
• Lubrication schedules 
• Burner information 
• Electrical information 
• Mechanical adjustments 
• Chain maintenance 
• Drive system information 
• Bearings 
• Troubleshooting guides 
• Recommended spare parts 
• Equipment drawings 
• Wiring diagrams 
• Exploded assembly views 
• Replacement part numbers 

This manual remains one of the best technical references available for existing JWI dryers.

 Even with a complete manual, many components eventually wear out.

Met-Chem supplies replacement parts for many legacy JWI dryers, including:

• Bearings 
• Roller assemblies 
• Drive chains 
• Chain sprockets 
• Gear reducers 
• Motors 
• Burner components 
• Temperature sensors 
• Thermocouples 
• Limit switches 
• Shaft seals 
• Rotary seals 
• High-temperature gaskets 
• Augers 
• Flights 
• Conveyors 
• Control panels 
• PLC upgrades 
• Electrical components 

If your original part is obsolete, our engineers can often recommend a modern replacement.

 Many JWI dryers have been operating for over twenty-five years.

While many repairs are economical, there comes a point when replacement becomes the better investment.

Common reasons customers replace older dryers include:

• Obsolete electrical controls 
• Burner upgrades 
• Increased maintenance costs 
• Corrosion 
• Reduced efficiency 
• Capacity increases 
• Safety improvements 
• Easier maintenance 

Met-Chem manufactures modern sludge dryers that can often replace older continuous dryers while reducing operating costs and simplifying maintenance.
