مصنع لتجهيز البوكسيت/Burnt Lime Graymont Leadership In Lime
Worldwide. We are driven by fire. Back in the sixties our engineers built the first Maerz lime shaft kilns with a lot of passion, thus laying the foundation for our success. Thanks to numerous innovative milestones we were able to strengthen our position as world market leader. In so doing we demand the highest standards of quality from ourselves.
Lime is a versatile product with many end uses. Some of the many uses include flue gas desulfurization in the coal fired power industry, water treatment (lime softening), antistrip additive for asphalt hot mix, corn stover treatment for tle feed, soil stabilization, drilling mud appliions in the oil industry, or pH adjustment in various industrial or water treatment processes.

Hydrated lime is a high purity fine white powder which is commonly known as 'slaked lime'. Appliions include water treatment, production of plasters and mortars, sugar refining, leather tanning, effluent treatment and fellmongery. Our hydrated lime product typically has 94% plus available lime as Ca (OH) 2.
· Burnt lime, hydrated lime, and some byproduct materials are also used. Calcium sulfate (gypsum) and magnesium sulfate (Epsom salts) are not materials. Lime quality is based upon the neutralizing ability as determined by its calcium carbonate equivalent (CCE) and by the speed of reaction as determined by its fineness.
· PPC Lime mines out of two quarries, while a rotary kiln plant manufactures the burnt product. The primary limestone quarry started operations in 1954 in Lime .
Working with the MEP was a seamless process whereas the MEP did most of the heavy lifting on the project. The MEP established excellent lines of communiion throughout the project, provided frequent updates, and worked well with our contractors through completion. I highly recommend the MEP as a valuable resource if you are looking to invest in your process or operation.
· Considerations of Hydrated Lime. Although hydrated lime is able to work more quickly than agricultural lime, more frequent lime appliions are actually required in order to maintain the positive effects. In addition to this, liquid lime often comes with higher operational costs since both water and lime must be toted across the field.

A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat → CaO + CO 2. This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO 2 is 1 ...
According to Boynton (1980), the United States is by far the world's leader in rotary kiln lime production with about 88% of its commercial and about 70% of captive plant capacity provided by kilns. The conventional rotary lime kiln has a lengthtodiameter ( L / D ) ratio in the 30–40 range with lengths of 75–500 ft (– m) and diameter of 4–11 ft (– m).

The new kiln of the rectangular type E2 will process limestone with gradings between 30 and 90 mm to produce 150 tons of burnt lime per day. Hard coal dust will be used as fuel. Maerz will supply key equipment for the lime kiln, such as: • Coal dust firing system. • Electric, measuring and control system.
Graymont's Otorohanga lime plant, situated 20 km north of the Company's Oparure quarry, operates two rotary lime kilns to manufacture highquality quicklime and hydrated lime products from the raw limestone sourced from the quarry. These products supply domestic customers in New Zealand as well as customers in the AsiaPacific region.
Lime has many more uses, especially in the chemical industry, than does limestone. Lime is a mineral made by heating limestone or dolomite in a kiln. Lime is used in a variety of chemical industries, in sugar processing plants, in steel mills, sewage treatment plants, and at paper mills.
