Biomass can be used in cement plants through two major modes, namely direct combustion and transformation into producer gas. Direct combustion of biomass in pre-heaters / pre-calciners and in the kiln by part-replacing the fossil fuel used in raising the temperature of the raw meal. This can happen in two ways: first, by mixing crushed and pulverized biomass with coal or petcoke for use in the kiln, and secondly, by direct feeding of biomass in solid lump form (such as pellets and briquettes) into the rotary kiln and / or pre-heater/pre-calciner combustion chamber. The biomass can also be transformed into producer gas (also known as ‘synthesis gas’ or ‘syngas’) and co-firing it in the kilns using a gas burner (Seboka et al., 2009).

Although the environmental acceptability of the use of tyres as fuel in kiln systems is dependent on individual plant performance, extensive environmental data has been generated for a variety of kiln configurations and fuel displacement. In general, the different test results have shown that TDF has no adverse effect upon the emissions; that is to say, the use of TDF has not caused a facility to exceed its operating limits (Gray, 1996; Environmental Agency, 1998; Blumethal, 1992a, 1992b). In comparison with coal, particulates, SOx, NOx and HCl emissions generally decline or remain constant with TDF use. Organic emissions, dioxins and furans are also observed to decline while changes in heavy metal concentrations are nominal (Gray, 1996; Scrap Tyre Management Council [STMC], 1992).

Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time. While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters.

LafargeHolcim is the global leader in building materials and solutions and active in four business segments: Cement, Aggregates, Ready-Mix Concrete and Solutions & Products. Following our pledge to net zero, our ambition is to lead the industry in reducing carbon emissions and shifting towards low-carbon construction.

Portland cement—the most widely used type of cement around the world, and the product specified in many modern construction codes—was patented nearly 200 years ago and has become an essential component of the built environment. In the years since, little has changed about the production process, according to Gaurav Sant, a professor of civil and environmental engineering at UCLA.

Binder, the secret of briquette making. For most of the briquette plant, add binder is the commonest way for the process. So, what kind of binder can be used for the briquette process? What are their advantages and disadvantages? What are the important factors we need to consider for choosing binder? Is it possible to make briquette without binder? Let follow the article and solve these problems.

Governmental regulatory agencies may be similarly conservative when it comes to construction codes. In the U.S., Europe and many other developed nations, these codes are generally based on portland cement chemistry, White said. Using a different product for a construction project would likely require the approval of the appropriate regulatory body—which may not always be easy to come by.

In addition to serving as an offset for non-renewable fuel demand, the use of biomass residues has the added benefit of reducing a cement kiln’s nitrogen oxide (NOx) emissions. Empirical evidence suggests that the reductions in NOx are due to the fact that most of the nitrogen (N) in biomass is released as ammonia (NH3) which acts as a reducing agent with NOx to form nitrogen (N2) (McIlveen-Wright 2007 as cited by Murray & Price, 2008). Interestingly, there does not seem to be a strong relationship between the N content in the biomass and the subsequent NOx emissions reductions (McIlveen-Wright 2007 as cited by Murray & Price, 2008).

It's even better if there is little or no wind and the skies are overcast. Heat, sunlight, and wind cause the overlay mixture to dry too rapidly. Rapid drying makes it harder to work and finish the overlay. These conditions can also cause undesirable plastic shrinkage cracks in the surface of the brand new overlay.

Maxton supplies the roller mill scale briquette machines for decades. We have strong technology and experience on the mill scale briquette making system. The well designed line will help you to reduce your investment and higher the system efficiency.

Most of the mill scale is used in steelmaking by way of sintering, direct use or briquetting.

Our Group does not only provide products. As part of LafargeHolcim cement solutions, we also offer a series of services to our customers, such as:.

Owing to the low production costs, the potential for immediate development and having large-scale development projects, Middle Eastern HBI suppliers have the ability to compete in the North East and Southeast Asia.

Switching from conventional fuels to alternatives fuels therefore presents several challenges that must be addressed. Poor heat distribution, unstable precalciner operation, blockages in the preheater cyclones, build-ups in the riser ducts, higher SO2, NOx, and CO emissions, and formation of rings in kilns are some of the major challenges (Roy, 1986; Pipilikaki et al., 2005; F.L Smidth, 2000).

The cement or mortar is mixed by first adding a portion of the water. The sand and cement are then poured into the water, and the mixture is stirred for several minutes. More water, cement or sand can be added if the mixture is too wet or dry.

This chapter presents the current fuel alternatives to fuel of fossil origin for cement manufacturing. The chapter introduces different potential alternative fuels that can be used in the cement manufacturing industry and how these fuels are to be considered in order to avoid negative effects on the final product. The type of fuel used in cement production is subject to the constraints imposed by any deleterious effect on cement quality, refractory life and emissions released to the atmosphere. The benefits of using alternative fuels are highlighted, showing that good planning is needed before the alternative fuel to be used is chosen. The chapter has included detailed study of the main alternative fuels used in the cement industry including petcoke, sewage sludge, used tyres, meat and bone meal, and agricultural biomass.
