Chapter 3 Proposal design

I Proposed production scale and design

The complete production line can according the market to produce glazed tile and split tile at the same time or produce single product alone. Proposal production scale is daily output 25,000 pcs glazed tile or 3000M2 split brick, calculation based on normal production time 11 month, the annual output is 8,250,000 pcs glazed tile or 990,000M2 split tile.

1 Proposal for glazed clay roofing tiles

Mainly produce 310X310mm glazed clay roofing tile considering produce 280X280, 200X200 and other specifications and accessories.

2 Proposal for split tiles

Mainly produce 240X240MM broom-finish outer tile, at the same time can produce 115X250 square brick, floor tile and 96X200 wooden grain brick. It also can produce 50X240, 52X240, 115X240 and other specification brick by change mould and cutting length.

II Product quality standards

Product quality takes current Chinese building material industry standard, clay roofing tile use JC708-1998Sintering tileas standard. Main parameters as below:

Water absorption: =12%

. Anti-bending strength: Ridge tile less than 1020N, S tile less than 1600N

Thermal stability: 1302-155 do not crack in three times

Anti-frozen: -203-15-25 15 time within 3 hours do not damaged

Allowed size difference

Specification Allow difference Allowed distortion

250B350 4mm 5mm

200B250 3mm 4mm

Split tile take JC/T457-2002Extruded ceramicfine stoneware tileas standard, main technical parameter as below:

Water absorption: not more than 6%.

Fast cooling and heating stability: No crack and explosion during the experiment.

Anti-freezing: No crack and glaze take off during freezing 20 times.

Bending strength: the average value is not less than 20MPa, single value is not less than 18MPa.

Wear resistance: Non glaze brick volume loss is not more than 400m2. Glaze brick need the two sides agreed.

Anti-chemical corrosion: a. Acid resistance: The mass losses will not more than 4% when corrosion been takes place for Non-glaze brick, glazed brick not less than degree B. b, Alkali resistance The mass losses will not more than 10% when corrosion been takes place for Non-glaze brick, glazed brick not less than degree B

III Production technology design

Production technology process

The material preparation of glazed clay tile and split tile are the same (the material formulas are not the same). Per inspection, the qualified material have been stock in raw material silo respectively, according to the formula weighting and batching the material, than use forklift sent to box feeder to put material uniformly into Lemon grinder, after crushing, the material powder will be sent to silo for stock, a belt conveyor will sent the raw material powder to double shaft mixer for mixing with water, then sent to a screen feeder for granulation, then stock into aging room.

Glaze clay roofing tiles production: After aging, the material will be sent to boxer feeder by forklift, the boxer feeder uniformly put the material into vacuum extruder for forming, after auto press machine press the tile, tiles will be load to drying frame automatically, after drying and auto glazing, it is fired in the tunnel kiln after double drying.

Split brick production: After aging, the material will be sent to boxer feeder by forklift, the boxer feeder uniformly put the material into vacuum extruder for forming, tiles will be load to drying car manually, after drying, manually load the tile into kiln car, than fired in the tunnel kiln after double drying. The fired brick will be splitting by splitting machine automatically, than inspect for warehousing.

2.Main production technological parameters

According to customer local material condition laboratory test, determine main production technology parameters as below:

Raw material granularity preparation: 40 mesh for glazed clay roofing tile, 80 mesh for split tile

Ageing period: =24h

Extruding moisture: 17-19%

Max. first drying temperature is 50-85, drying period is 24h, residual moisture
