Flue gas desulfurization (FGD) is a technology used to remove sulfur dioxide (SO2) from the exhaust flue gases of fossil fuel power plant. Limestone-gypsum flue gas desulfurization process is the world's most widely used FGD technology. About 90% of Japan, Germany, and the U.S. power plants use gypsum desulfurization process, which is wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime.

SBM has been engaged in limestone grinding for more than 30 years. Our high quality grinding plant and experienced service will perfectly meet your powder production requirement for FDG.

Raw materials of limestone-gypsum FGD sorbent:

Raw material: Limestone

Fineness requirement: 200 mesh

Limestone grinding plant: MTM mill, MTW mill

SBM Limestone sorbent production plant (1.6~0.045mm)

SBM offers two kinds of limestone grinding mill for FGD sorbent production—MTM Trapezium Grinding Mill, and MTW European Grinding Mill, whose product finesse can vary from 1.6~o.o45mm. Both grinding plants are proved to be favored by our customers to produce limestone sorbent for FGD.

• MTM Mill
• MTW Mill

• MTM Trapezium Mill is a world leading level industrial mill.It is designed by our engineers and technical workers ,basing on many years industrial mill design ,adopting world leading powder making teachnology.

  - High grinding efficiency Inverted trapezium roller and ring can reduce materials' slip velocity. - Steady and low noise Press spring keeps the balance. Resilient connection ensures reduces noise. - High grain finesse Product powder precision is improved by 50% compared with Raymond mill.

• MTW continencial trapezoid mill are designed by our experts, according to advices of customers' long-term experiences. They adopt bevel gear integral transmission, inner light-oil lubrication system, arc whirl tube and another proprietary technology.

  - Special transmission Bevel gear integral transmission compact structure and simplify installation. - Efficient lubrication Bearing lubrication realized without oil pump or lubrication station. - Long service time Curved surface edge of alloy material is more wearable and easy to be changed.

Limestone grinding process (final powder fineness: 200 mesh)

Limestone raw materials are firstly crushed by jaw crusher to specified size, and then elevated into a hopper. Then vibrating feeder sends evenly and continuously the materials into the grinding chamber for powder processing.

The ground limestone grains are carried by air from the blower into the classifier for classification. The finer powers are blown into cyclone collector, and the rough grains will be recycled back into the grinding chamber for further grinding, forming a closed circuit. Final products of 200mesh and less in size are poured out through out-put valve.
