Wear resistant concretes TRIBET
Advantages of a lining from wear resistant concrete:
- Uniform and compact protection surfaces without cracks
- The lining can cover equipment of any complex shape
- Quality variations of the concrete kinds:
- A suitable concrete kind is selected, according to the local exposure to abrasion
(the transition between different kinds of concrete is continuous)
- A suitable thickness of the protective layer is selected, according to the local exposure
to abrasion (the transition between different thicknesses is continuous)
- The perfect gripping on the surface is ensured by the weld on steel mesh inside the lining
- Simple and fast application of the lining in the form of classic masonry works
- Easy and safe handling in bags to the lining application places
- Up to 4 times higher wear resistance than cast basalt
Recommended conditions suitable for the wear resistant concrete applications:
- the grain size of the conveyed abrasive material to 4mm
- operating temperature till to 400°C
- angles of incidence of the conveyed material to about 30°
(at incident angles to 15° - excellent wear resistance of concrete; to 30° - resistance is very good;
to 45° - satisfactory resistance; at angles above 45° resistance drops significantly and the angles of incidence over 60° using concrete not recommended)
- the flow velocity of the conveyed material to about
Application of wear resistant concrete:
- plastering - solid concrete application on larger surfaces on welded mesh holding in thickness from 15 mm
- casting - pouring a thinner concrete into confined spaces, narrow pipe or vertical surfaces (thickness arbitrary)
Types of wear-resistant concrete Tribet supplied by Tribo s.r.o.:
Characterization: wear resistant concrete with extreme abrasion resistance
Abrasion resistance*: 0,8 – 1
Using: protection of industrial equipment exposed to extreme abrasion
Examples: bends in pneumatic transport for highly abrasive particles (coke and coal dust, cement, slag, etc.),
the most stressed areas in the mills, crushers and separators
Characterization: wear resistant concrete with high abrasion resistance
Abrasion resistance*: 1,2 – 1,4
Using: protection of industrial equipment exposed to high abrasion
Examples: bends in the extraction system (suction) highly abrasive particles (coke and coal dust,
cement, slag, etc.), cyclones, bends in suction piping, straight sections in the air-operated
transport, conveyors, chutes, separators, mills
Characterization: wear resistant concrete with very good abrasion resistance
Abrasion resistance*: 3,5 – 3,8
Using: protection of industrial equipment exposed to moderate abrasion
Examples: straight sections in the exhaust system of abrasive particles,
less stressed parts of cyclones, chutes
