Process for using mill scale in cement clinker production

A process for using mill scale, having hydrocarbons associated therewith, in the production of cement clinker using a rotary kiln system, comprising the steps of: blending and preheating feedstock material; transferring said blended and preheated feedstock material to an area in said rotary kiln system where combustion is taking place; adding an amount of said mill scale to said blended and preheated

Properties of High Density Concrete with Mill Scale Waste

This study concentrates on the utilization of mill scale waste for the production of ballasts used in washing machines. Ballasts act as counterweights in washing machines and require a standard weight. Thus, high density concrete is used to produce ballasts occupying lesser volume for the given weight. Mill scale acts as a high density aggregate and is used as a complete replacement of fine and coarse aggregates.

Uses description Mill scale

The heavy concrete is one obtained by mixing at least cement, a heavy aggregate, and water, and is characterized by containing a heavy fine aggregate including hot-scarfing particles generated in the step of hot-scarfing steel slab surfaces. Mill scale can be mixed with the feedstock.

Mill Scale Mill Scale, Everything You Need To Know

Mill scale is being used in place of standard concrete as counterweights in washing machines. The material is mixed with water and used as filling material. These counterweights are used in the manufacturing process of basic metals as well as for production of general machinery and transportation equipment. The result is a smaller counterweight which allows better use of space in design and

How concrete is made material, manufacture, making,

Portland cement, the kind most often used in concrete, is made from a combination of a calcareous material (usually limestone) and of silica and alumina found as clay or shale. In lesser amounts, it can also contain iron oxide and magnesia. Aggregates, which comprise 75 percent of concrete by volume, improve the formation and flow of cement paste and enhance the structural performance of

Mill scale AEIFOROS METAL PROCESSING S.A

Mill scale. A by-product of the steel production, mill scale is an attractive alternative source of iron oxides for the cement industry and the chemical industry. Mill Scale The mill scale is produced during the milling process from the sudden oxidization of the hot iron products. The main component of the mill scale is iron oxide (>95%) The mill scale can be used as: 1. Additive in the

Process for using mill scale in cement clinker production

23/03/2004· Thus, a first disadvantage in using mill scale in the production of cement clinkers is the necessity of removing any hydrocarbons that may be present. Further, in the prior art process, as far as is known, when the mill scale is attempted to be used in making cement clinkers, it is first finely ground with the other feed stock materials

Mill scale Wikipedia

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.

11.6 Portland Cement Manufacturing

17/08/1971· Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these materials are produced in portland cement manufacturing plants. A diagram of the process, which encompasses production of both portland and masonry cement, is shown in Figure 11.6-1. As shown

Concrete Production an overview ScienceDirect Topics

Concrete production is now, of course, a mature technology. The ancient Greeks and Romans both produced mortars that may be considered to be the forerunners of today’s concretes, while “modern” concretes have been in use since the middle of the 19th century. These concretes now constitute a highly sophisticated family of materials

US6709510B1 Process for using mill scale in cement

A process for forming cement clinker using mill scale that may have hydrocarbons associated therewith. Normal feedstock material is preheated and then transferred to a combustion area. The mill scale is also transferred to the combustion area where, during the process of burning a material, the unwanted hydrocarbons are volatilized and converted to harmless gaseous products (by combustion
