LIME ROCKS
THE VERSATILE MINERAL
Various forms of lime are used in environmental, metallurgical, construction, and chemical/industrial applications, and more.
However, the largest single use of lime remains steel manufacturing, where it is used to remove impurities.
In construction, the dominant use of lime is in soil stabilization for roads, earthen dams, airfields, and building foundations.
STM patented bio binder
STM developed its own free formaldehyde binder for mineral fiber based on Maillard reaction.
STM Bio Binders can be adapted to the characteristics of existing plants.
See patent WO 2013/179323
STM dual density machine
STM DUAL DENSITY MACHINE to produce panels with upper layer with higher density
- Upper layer 20 mm up to 200 kg /m3
- Lower layer 100 mm typical 100 kg/m3
Twin spinning machine production lines
Production lines with twin spinning machine for production capacity up to 70.000 ton per year.
Drum split formings
New high efficient drum type split forming allowing very low power consumption with perfect binder distribution and reduced maintenance.
BK Shaft Kiln Last generation
The BK kiln is equipped with external combustion chambers at two levels. A internal cylinder creates an annular zone through which the material passes.
The combustion gas is recirculated in the empty central cylinder and by controlling its temperature it is possible to produce different qualities of lime.
Fully automatic operation fine control of combustion system, have improved the quality of the performance of the kiln.
