National policy
August 20, 1999 the State Council issued the "Forward Ministry of Construction , the State Economic and Trade Commission , Ministry of Science , the State Administration of Taxation , the State Quality and Technical Supervision , the National Building Materials Bureau notification < on promoting modernization of housing industry to improve housing quality advice > The " [ SCS ( 1999 ) No. 72 ] , "opinion " clearly states : From June 1, 2000 , the coastal cities and other urban land resources are scarce , prohibit the use of solid clay brick and other clay products according to restrict possible conditions production and application . From that day onwards, China 's real ban officially kicked off.
Over time , the State Council and the Ministry of Land and other ministries of the "no real " work more and more attention , "no real " increasing the intensity . June 2001 , the state identified 170 cities nationwide , requirements before the end of June 2003 , to complete ban on the use of solid clay targets in residential construction , and achieved good results.
By 2005 , all provinces brick office are on the " real ban " within the scope of the jurisdiction of the schedule to make clear arrangements. A ban on real storm begins !
At the same time the state has adopted a series of preferential policies for enterprises of new wall materials , such as from the date of declaration of new wall materials from corporate income tax shall be exempted for three years ; slagging unit may use any name to the new wall materials fee , if necessary, should be given freight subsidy ; many local governments also clay bricks production unit or units levied 8 yuan / square meters of brick fund , direct subsidies to new wall materials production enterprises.

Industry overview
Our unburned brick and block development can be divided into three stages: from the beginning of the eighties there are manufacturers of small-scale production, but poor product quality, production speed is slow, the device is relatively backward , there is little market ; to nineties, as well as to further improve the production process of upgrading equipment , block product quality and production speed has been some improvement , but still can not meet the state requirements for large-scale promotion ; 99 years later , with the the introduction of the national ban on real policy , the rapid development of the whole industry , from production equipment to the production processes are becoming more mature, and has to fit the requirements of the national large-scale promotion , in line with national requirements for the construction of a conservation-oriented society .

Market analysis
According to information , under normal circumstances , a prefecture-level city in brick around 1.2 billion , the amount of a county-level city with a brick is about 300 million . The current situation is that the brick are used in many parts of the old equipment , daily output of more than two million units are particularly small, doing most will produce six or seven million each year , but the quality is not guaranteed . This resulted in most places of unburned and blocks from the quality, quantity simply can not meet the needs of the building, which led to the red brick can not withdraw from the market as soon as possible , because the state can not stop building . However, in accordance with national policy , clay bricks sure to completely exit the stage of history, of course, to the gradual increase production of new materials and step by step . Thus, the prospect of new wall materials production is very good, promising career .

Choice of raw materials
Optional sand ( including mechanisms ) , sand , stone , shale, white ash , cinder , slag, fly ash and other materials to produce one or more products, cement or no cement products. Selection of raw materials to the actual local situation , the key is to choose the source of stable , low-cost raw materials , which can ensure normal production and profits.

Production scale
1 location : location near the main source of raw materials to , so eliminating the need for a large part of the short shipping . As for the finished brick freight yard should be considered regardless of the position in which users are scattered .
2 Site : 12 acres of grounds , namely, more than 8400 square meters , the audience without hardening , with waste BEDDING , smooth can be.
3 people : 1 person controlling , feeding two people ( including the board ) , the board 2, pushing billet 4 people, palletizing five. Total 14 people.
4 Production : Organizational daily single shift ( 8 hours ) of production , the daily output of 49,920 blocks ( standard brick ) , the annual output of up to 16,473,600 by 330 days to calculate block ; daily two- shift production if the organization , the annual output of up to 32,947,200 block .

Costing and economic benefits
Due to the different raw material costs over the country, where we use the local situation to be described.
Main materials : fly ash, powder, rice stone, cement

Social
1 beautify the environment : the use of mining waste brick is turning waste into treasure, increase efficiency , landscaping, a good way to comprehensive treatment , the use of mining waste brick , the device can be swallowed waste 50,000 tons per year . Can reduce fear residue field owned 25-35 million (including land cost ) , and can reduce waste covering 30 acres , up 3.5 million kilograms of grain .
(2) conservation of arable land : the use of mining waste brick , the annual festival to 25-40 acres Nationally, the number of saving farmland will be inestimable .
(3) Energy conservation : the use of the device brick production process to replace the country for thousands of years sintering methods, eliminating the need for complex steam curing process , per 0.1 kg of coal fired brick block count , annual savings of coal 1600 -2500 tonnes.
4 Decontamination : brick with the device , do not build the kiln , not built chimney.
