Sell Crude Golden vermiculite

Description

oliating or expanding into worm-like pieces. The name 'vermiculite' is derived from the Latin 'vermiculare' meaning worm-like. This characteristic of exfoliation, the basis for many commercial uses of the mineral, is the result of the mechanical separation of the layers during the rapid conversion of contained water into steam. The increase in bulk volume of commercial grades is 8 to *2 times, but individual flakes may exfoliate as many as *0 times the original size. There is also a color change during expansion that is dependent upon the chemical composition of the vermiculite and the furnace temperature. The bulk density of crude vermiculite or vermiculite concentrate is in the range of *******0 kg/cubic metre. (****0 lb/cubic foot) and exfoliated or expanded vermiculite is in the range of *4 - **0 kg/cubic metre (4 - *0 lb/cubic foot).
