This situation is therefore favourable for a cement plant to be established in Namibia. 1.3 Location The location of the quarry site and proposed cement plant is on the farm Sargberg (Farm No. 585) – refer to Figure 1. The site is situated 16 - 17 km north-east of Otavi in the Otjozondjupa Region of Namibia

Aug 20, 2015 Aug 20, 2015 Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are

the improvement?” This paper focuses on defining key performance indicators for the maintenance function, not the maintenance organization. Figure 2: Asset Utilization is an example of a manufacturing level key performance indicator

* Mined-out areas would be converted to plantation / agri-farm and water reservoirs as envisaged in the mining plan partial reclaiming already done. * Socio-economic improvement measures are being undertaken in the project buffer zone as envisaged. 07 Break up of the project area. a) Submergence area ( forest & non-forest ) :

behavior of works to mining the risk and provide safety measures.[4] Bartolozi, L. Castiglione, explains that Continuous improvement day by day to increase the efficiency, In cement manufacturing process to eliminate all wastages. In cement manufacturing process raising etc

ML Area : 21.925 ha Recommended Greenbelt Area During Mining Plan period : 1.5 ha During Conceptual Stage : 7.325 ha Saplings planted so far : 750 Extent of existing greenbelt area : 0.35 ha Area covered with greenbelt : Dumps, bunds

Nov 01, 2018 Quarry areas: Areas to review include: The type and condition of mining equipment and its ability to operate at the current and higher rates; Reserves of limestone and other raw materials, for example clay, gypsum, etc.; Expected period over which raw material will last under the current production volumes and desired / future volumes; Quality and status of mineral concessions; Validity

Grinding is a highly energy intensive process in the cement industry. Approximately 60 – 70 % of the total electrical ene rgy used in a cement plant is utilised for the grinding of raw materials, coal and clinker. Various technological improvements from the conventional ball mills in this area include:

The Lehigh Cement operation is separately authorized under a Use Permit. A use permit for the cement plant was first issued on May 8, 1939. The use permit was modified in June 1950 and May 1955 to add rotary kilns to the operations. The County approved a use permit modification associated with modernization of the cement plant on December 5

SPECIFIC CONDITIONS S.No Specific Condition Compliance Status i. No construction work at the proposed project site should be started without

The $200 million plant modernization project’s most visible improvement is a 320-foot tall twin concrete tower within which limestone will be heated to 1650 degrees Fahrenheit before it goes into a new kiln that converts it into cement. The plant modernization also includes an entirely new mining area and crusher that utilizes a one-mile long

The combined area of the Limestone and Shale Quarries disturbed by mining encompasses approximately 234 acres. The mine ceased operation in 2009. The mine contains hard rock mining and crushing equipment, maintenance shop, office, rock storage silos, and a belt conveyor that travels approximately 3 miles to the Cement Plant
