1. INTRODUCTION AND GENERAL DESCRIPTION
KIVI GRUPP needs a rotary drum to use as a dryer for LIMESTONE.
ANIVI experience shows that products which in theory are quite similar present in practice
completely different behaviour. Prior to a final supply sample of the product could be required.
The connecting ducts between the dryer, bag filter and fan are not included in our scope of
supply, however if you so require, we can take charge of their construction drawings.
In the technical study we have considered that the corrosion, and chemical activity of the product
in general, either in itself or due to previous processes, is inexistent and does not have negative
effect on the use of carbon steel as construction material.
Design inlet and outlet moisture are that showed under the working conditions. Lower inlet
moisture or higher outlet moisture will decrease the energy consumption and incresase the plant
capacity. On the contrary higher inlet moisture or lower outlet moisture will increase energy
consumption and decrease the plant capacity
On the basis of the mentioned gas energy value and condisering a Natural Gas density of 0,8
Kg/Nm3 we have simulated two scenarios with different inlet moistures and indicating the
different energy consumption.
