Most of the double wall stove pipe allows for 6" clearance from wall combustibles and 8" from ceiling combustibles. Using a "Heat Shield" on a single wall stovepipe allows you to reduce the clearances from 18" to 6" to the wall and 9" to the ceiling. Many think stovepipe can run from the wood-stove, right up through the ceiling and roof.

Cement milling Question 1. Recently, we have changed the grinding balls in the second chamber of our mill to a lower size balls. The effect is a 10 per cent of reducing in fineness at the discharge of the mill, therefore the efficiency of our separator is better, but we were waiting for an increase in the production, nevertheless it is the same than past periods with bigger balls.
Cement received in bags shall be prevented from coming into contact with any dampness or moisture. Cement bags shall be stacked on wooden planks maintaining a minimum clearance of 200 mm from the floor. A minimum clear space of 450 mm shall be provided between the stacks and any exterior wall.

Engineers insert a top plug after the cement slurry, and the top plug is then followed by a displacement fluid (bottom left). Pumping the displacement fluid forces the top plug downward until it lands on the bottom plug, thereby isolating the casing interior and annulus and filling the annulus with cement slurry (bottom right).

This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
