RTSM-0.5AD horizontal lab disct bead mill is mainly applied for the grinding of water-based coating/paint, pesticide, pigment,dye etc. According to different material, the inner chamber and rotor could be made into ceramic material. RTSM-0.5AD, the unit designed specially for lab research and small batch experiment, is the ideal model for laboratory.


Grinding System
Grinding chamber volume: 0.5L

Outer chamber material: all body stainless steel

Advantage: Easy maintenance and less corrosion 

Inner chamber material: wear resistant hard alloy or ceramic material

Advantage: High wear resistant. Two material for selection, for different application
Grinding rotor material: Hard alloy/Zirconia
Grinding rotor structure: disc
Main shaft material: SS304
Bearing: Imported SKF
Grinding chamber working pressure: 2KG
with triple cooling system at bearing, mechanical seal and chamber to ensure a good cooling to the material and keep safe of machine
Sealing system
Mechanical sealing type: Assembled double end mechanical sealing. Longg durability , easy maintenance.
Dynamic-Static ring material: wolfram carbide. High wear resistance. It could form a perfect water/oil film to prevent the material going into the mechanical sealing. Better sealing performance
Mechanical sealing support material: stainless steel(304).
Material transportation system
Material Feeding: ARO Pneumatic diaphragm pump
Material Discharging: Dynamic discharge (static-dynamic ring)
Separate material: Wolframe Nitride
Electrical and Control system
Motor: 2.2KW 
Motor Brand: Customized (Standard: Siemens Motor)
Power Supply: Customized (Standard: 220V 50HZ Single PH)
Operation: Push Button
Protection system
Air pressure protection, material pressure protection, water pressure protection, material temperature protection etc. All these points are set in control box, once the pressure or temperature has passed the set values, the machine will stop work to protect itself.
When mechanical sealing cooling oil is lower than normal lever, the machine will stop automatically for self-protection


Steady Working

RTSM-0.2BJ a Root self-design mechanical seal with good sealing effect, steady working. The mechanical seal cooling liquid could be selected based on different material, avoiding the potential cross-contamination due to leakage.

The lab grinding result can be enlarged to industrial production

RTSM-0.5AD has exactly the same structure with RTSM-AD industrial series, its lab experiment result can be enlarged to industrial production.

Easy operation

RTSM-0.5AD is operated by simple electric system. Even a new staff can easily operate the machine by start,stop,speed up and speed down.
