Manufacturing process of CLAY BRICKSMost bricks be formed by one of two basic processes. Extrusion moderately stiffed texture is mixed with clay body which is loaded into extruder worm rear end force it into a die through pushing it along a barrel .depending upon how much clay will shrink in drying and firing off-key process the die is made larger considering this The clay emerges as a continuous brick shaped column. Initi on the wholey this is smooth but it can be modified by removing a thin sliver from the top and sides use a taught wire to produce a wiredrag effect or by placing textured rollers over the column to create a rusticated effect or even by blasting the column with sand. The clay column is therefore cut into single bricks and palletised ready for the dryers or in many factories, atomic number 18 loaded directly onto kiln cars. Extruded bricks can be solid but cannot be frogged & are principally perforated. Soft spoil do workingSoft mud mouldingBricks ar e constituted in mould boxes through some number of processes . Many methods can be applied but all have a common theme. A mould release metier stops the clay from sticking to the box (sand, oil or water) when cushy clay is thrown into a mould,. The bricks are turned out & the superfluous clay is stuck off from the top of the mould. This is done by hand by a craftsman who would create one brick at a moment. This is slow, pricey & labour intensive used In these days only for generating especial(a) shapes or decorative bricks. For standard bricks large automated machines can be replicated the hand-making procedure much quicker by taking use of banks of mould boxes on a circuit where the boxes are filled with pre sanded clots of clay, washed, sanded struck off level and the formed brick turned out.... ...re than 60 F/h by introducing steam clean standard weight is generally cured at 150-165 F , whereas light weight at 170-185F . afterward reaching curing temperature ste am flow is shut down .blocks are then left over(p) for tweak in moist hot air for 12 18 hours. After this block is left for drying by exhausting moist air and progress increasing the temperature of kiln which took about 24 hours.2) High pressure kiln pressure (autoclave) temperature is generally higher about 300-375 F and pressure is 80-185 psi block is left to soak for 10 hours , pressure is then decreased rapidly , because of which trap moisture of block is released quickly. It is more costly process but it takes slight time.Referenceshttp//www.madehow.com/Volume-3/Concrete-Block.htmlhttp//dcmsme.gov.in/reports/glass/HollowBricks.pdfhttp//www.ibstock.com/pdfs/technical-support/TIS16Howbricksaremade.pdf
