The application of FGD gypsum briquettes

The application of FGD gypsum briquettes




In coal-fired power plant, flue gas which contains sulfur oxides is air pollutant resulting in acid rain. People handle this problem by burnt lime powder. Thus, FGD gypsum is formed which could be used as retarder in cement industry. This is an innovation for the waste recycling.

Gypsum briquette machine is necessary for the utilization. Different from other materials, in the gypsum briquetting, no additive is needed.

Core part of gypsum briquetting plant is the two counter-rotating rollers. When materials come down to the gap between rollers, pressure grows heavier and heavier. Solid gypsum briquettes are formed.

The application of sponge iron briquette machine in steel industry

The application of sponge iron briquette machine in steel industry




DRI (sponge iron) is made from high grade iron ore in a low temperature environment by reduction reaction. Stable composition, little impurity, low carbon content, sponge iron is mainly used as raw material in electric furnace for steel making. Also, it could be used as coolant in converter or metallurgy powder after twice reduction.


In recently year, steel and iron products are treading towards smaller in size, upgrading in function, so non-metallic materials and non-ferrous metal content increases. This results in the decreasing quality of waste steel. As waste steel comes from different materials, chemical composition varies greatly and is hard to control. This brings difficulty for electric furnace steel making. If certain ratio sponge iron is  mixed (30%-50%) with waste steel as diluent, it will not only increase the uniformity of steel, but also improve the physical property. So, DRI is not just substitute of waste steel, also raw materials for making high quality steel.



As a test on 3TPH electric furnace shows, if sponge iron is mixed, per ton of furnace burden saves electricity 27%, time 28%, oxygen consumption 22%, physical property improves significantly. This increases capacity of electric furnace and reduces energy consumption and cost.

However, sponge iron need to be fed into furnace in briquettes, in either ball shape or cylinder shape. Sponge iron briquette machine is what we supply. If you are interested, please visit my homepage on Linkedin.

1.  Usually, hydraulic briquette press is equipped with screw feeder that ensures raw material comes into roller constantly and uniformly. It is driven by electromagnetic speed-adjustable motor, belt pulley and worm reducer. Due to the constant torque of electromagnetic speed-adjustable motor, when the quantity of material that is fed into matches with the quality that machine need, briquettes quality is stable.

2.  When the material is overfed, piston rod of hydraulic cylinder is overloaded. Hydraulic pump will stop at such a situation, overflow valve is opened to get oil back, energy accumulator has a buffer action on the pressure. The displacement of piston rod widens the space between the rollers. Hydraulic pressure system return to normal.

3.  Driving system includes motor, triangle belt, reducer, counter-rotating gear, roller. The machine is powered by electromagnetic motor. By the transmission of belt pulley, gear reducer, coupler, power is transmitted to the driving roller. Counter-rotating gear ensures the synchronized operation of driving and driven rollers. Hydraulic protection device pumps high pressure oil into cylinder, piston makes displacement on the shaft direction. The front end of piston rod is connected with shaft bearing to meet the pressure requirement.

What factors have impact on the capacity of roller briquette press?

What factors have impact on the capacity of roller briquette press?



Capacity of a machine is an important economic factor. When roller briquette press is processing a certain material, the capacity varies. 
What will influence the capacity?

1.  Specific gravity of the material
2.  Property of material
3.  Diameter and width of the roller
4.  Rotation speed of the roller
5.  Pockets on the surface of tires.
