In many cases, this fan limits clinker production by limiting the gas flow through the preheater. It consumes about 10 percent of the total power used at the plant. Large gas flows, high gas temperatures and static pressure, and the potential for material abrasion and buildup on the impeller makes the design of a fan for this application complex. Selecting the optimum fan and drive requires careful consideration of each application and of all design options available. Preheater fans proposed by vendors in recent projects vary significantly. For example, some vendor's proposed single width, single inlet type fans, while others proposed double width, double inlet type fans. Some vendors proposed radial blade fans while others proposed backward curved or airfoil fans. The degree of wear protection also differed significantly. This paper discusses various topics that are important when selecting a fan and drive for this application. Topics discussed are: the process requirements and conditions, the options available for fans and drives, the advantages and disadvantages of fans and drives available, and the impacts of each fan and drive on capital and operating costs.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

However, in many cases these same plants have chosen to use very traditional technology for finish grinding-typically a ball mill and separator. With today's power price issues in the US, and the large experience base that the rest of the world has with the use of new technology in finish grinding, the US market is considering the use of modern vertical roller mill technology for cement grinding. This paper discusses the different options available for upgrading the capacity of an existing plant, provides comparisons of operating costs, simplicity of operation, product quality considerations, etc., based on the OK mill project at Phoenix Cement Company (PCC) as the first vertical mill for cement grinding in the US.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

This process is referred to as 'spotting' or 'inching'. Examples include cement grinding mills (both raw and finish) and metal processing rolls. These motors are usually medium voltage (>2300 V). Two methods of spotting motors have been used in the past: (1) bumping the motor with the medium voltage motor starter, and (2) an electromechanical inverter. This paper describes the application of a low voltage (460 V) PWM adjustable speed drive to medium voltage motors for spotting purposes. The drive is capable of rotating a synchronous or induction motor at low speed under manual control to position the machine attached to the motor to a desired position.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

Large scale production upgrades of tube mills have been available since 1990, when the roller press has been set up for semi-finish-grinding. The major reasons for upgradings are: production increase, lower energy consumption and the market demand for higher cement qualities. All three arguments should be fulfilled for the cement mill conversion, introduced in the paper. A pregrinding circuit, consisting of a roller press and a separator has been selected, to more than double the capacity of the existing tube mill. While this project was one of the first of its nature, a number of problems have been encountered. Finally, a second upgrading step had to follow the first one, partly replacing major equipment. A new process, even new machines have been introduced, giving satisfactory results. Finally, it has become a new standard for todays applications. The project introduced is an example for a number of grinding plants that still need the second step of upgrade.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.

These new rules represent the tightest emissions regulations to date and will have an effect on new and upgraded cement production lines hereafter. The MACT rules do not regulate NO/sub x/ or SO/sub 2/ and CO is only regulated when firing waste fuels; however, each state regulates these emissions for a new cement production line. It is important to note that states can mandate even lower limits than those given in the MACT rule and add additional emission requirements. As the emission limits get tighter and tighter, it becomes critical to be able to accurately predict gaseous emissions and incorporate the proper system design to meet permit requirements. A number of possibilities exist to minimize gaseous emissions. These include systems designs, like the low NO calciner, and \"tailpipe\" designs, like the wet scrubber. Some methods are much simpler and less expensive than others. In some instances the viability of a new production line can depend on the extent of added costs required to achieve environmental compliance. This paper focuses on emissions of NO/sub x/ SO/sub 2/, CO, and THC, and the various methods that can be used to control these emissions within current limits.","PeriodicalId":103359,"journal":{"name":"IEEE-IAS/PCS 2002 Cement Industry Technical Conference.
