3. Site Selection and Overall Planning
3.1 Site Selection
3.1.1 The site selection shall not only meet the requirement of the industrial distribution and
regional construction planning, but shall also comply with relevant regulations, laws and
provisions of the previous work.
3.1.2 The site selection shall be determined according to the construction scale, raw material
and fuel source, transportation and communication, power and water supply, engineering
geology, environmental protection, enterprise cooperation conditions, site existing utilities
and produce market flow direction through the technical and economic comparison.
3.1.3 The plant site should be set near the limestone mines, and it shall be provided with
transportation and communication conditions which have economic feasibility. At the same
time the site selection shall be conducive to the cooperation between the adjacent enterprises
and towns. However, the site should not be set far away from the town or inaccessible areas.
3.1.4 The site shall supply enough power and water source required for the continuous
production requirement and development planning, while its out-of-factory power
transmission and water delivery lines shall be short, nimble and also facilitate the
maintenance and management.
3.1.5 The plant site shall make full use of the topography, so as to shorten the interior
transport distance and conserve land.
3.1.6 In satisfying with the short-term site area required and under the premise of saving
capital investment, the site shall be reserved with developmental space according to the
long-term planning requirements.
3.1.7 The site shall be selected to meet the engineering construction requirements in respect
with the engineering geology and geohydrologic conditions, and it shall avoid the useful
mineral deposit.
3.1.8 The site shall lie on the windward side in the town and residential area where the
minimum frequency wind direction all the year around is present, but it shall be in the
wind-haul district.
3.1.9 The site elevation should be higher than 0.5m plus the flood protection standard stage.
In case of less than the above elevation, the plant site shall be equipped with flood control
facilities, which shall be built in the initial project. When the site is located in water logging
areas and draining water-logged facilities are available, the site elevation shall be designed to
be 0.5m plus the water logging level. When the plant site is located in a mountainous area,
torrent prevention and drainage facilities shall be set thereof.
3.1.10 The flood protection standards of the cement plant shall be in accordance with relevant
regulations of current national standard "Flood Protection Standard" GB 50201. The new
dry-process cement plant shall also be in accordance with those specified in Table 3.1.10.
Table 3.1.10 Flood Protection Standard of New-process Dry Method Cement Plant
Class Plant size Return period (year)
Ⅰ Large-sized ≥100
Ⅱ Medium-sized ≥50~100
Ⅲ Small-sized ≥25~50
Note. The plant with multiple product line improves its flood protection standard accordingly.
3.1.11 Bridge culverts, tunnels, vehicles, terminals and other external conditions or
transportation modes shall meet the requirements for transporting bulky or large pieces of
equipment.
3.2 Overall Planning
3.2.1 The overall planning of the cement plant shall not only meet the requirements of the
regional plan or town planning of the regions, but should also be cooperated with the urban
residential area and the adjacent industrial enterprises in environmental protection,
transportation, power utilities, repairs, storage, culture and education health, living facilities.
3.2.2 The overall planning of the cement plant shall not only arrange the plant site rationally,
but shall also handle the relationship between the plant site and the limestone mine, silicon
aluminum raw material mine, water source, water supply and water treatment fields, sewage
treatment plant, total receiving substation, railway integration station, out-of-factory railway
or water transportation terminals.
3.2.3 The overall planning of the cement plant shall correctly handle the short-term and
long-term relationship. The short-term planning shall be laid rationally and concentrically,
while the long-term planning shall allow development spaces, take over land in phases and
shall not take over land for preservation.
3.2.4 The selection of the external transportation mode of the cement plant should meet the
following requirements.
1 External transportation mode shall be determined according to local transportation
conditions When the plant is located near the natural water systems, better ports and
navigation conditions are present, so water transportation shall dominate the plant; when land
carriage is adopted, the railway and road transportation plans shall be determined according to
the traffic, transport distance, convergence conditions through the comparison, in addition, the
railway and highway traffic ratio shall be determined by the market supply conditions.
2 The cement bulk exportation facilities shall be configured according to the receptive
ability, transit storage and handling transportation conditions of the plant site to the bulk
cement, and the proportion of the bulk cement in various forms of transport shall be
improved.
3 The selection for the out-of-factory railway convergence point and plant-line-leading
direction shall not only be closely cooperated with the plan layout and vertical design of the
plant through the multi-determined technical and economic comparison, but also the positions
of the facilities like enterprise station, railroad track scale and locomotive readiness scale
production lines shall be planned.
4 The mounting of the enterprise station shall be determined according to the traffic size,
operational requirements, management methods and integration point conditions, and shall
take full advantage of the road net railway yard capability, but shall not be constructed
repeatedly. When the connection line and leased railway locomotive are allowed to be
mounted in addition on the convergence station, the goods transfer approach should be
adopted, and the enterprise station may not be set.
5 The connection between the out-of-factory road and highway of town or residential
area in the cement plant shall be smooth, short and fast. Moreover, convenient road
connection shall be set between the plant si...
