calcination molybdenum oxide v

Nowadays, in china most of factory adopts the reverberator and outside heating rotary kiln to calcinate the Molybdenite, abroad factory some adopts multiple hearth roaster and internal heating rotary kiln. With the development of Molybdenite market, the capability of Molybdenite roaster and reclaiming of end gas are most of important.
the internal heating rotary kiln designing and manufacturing by our have apply in some factory in china ,so proved that this kind of method to calcinate the molybdenum oxide is successful . And this kind of method has more advantage than other method for calcinating molybdenum oxide.

Process:
First , set molybdenum mine powder to dryer for drying and homogenization, then sent to bins .feed to calcinator with the gas heated by direct fuel-coal hot air heater .After calcination molybdenum oxide vent from outlet . With thermoregulator, swirler,bag house collector , electrostatic separator the SO2 gas go to reclaiming system .


The technical feature:

1.     Internal heating rotary kiln adopt direct heating method, so that advance he thermal efficiency.
2.     Drying before the calcinating can reduce the acidified materials , and the grain homogeneous
3.     System reclaiming adopts the twice collecting, advance the reclaiming efficiency.
4.     Negative pressure operation so that not powder leak out.

The technocal characterstic:

1.     Output :7-8 tons /day
2.     containing of sulfur less than 0.07%
3.     The coal consuming : 350kg coals of one ton molybdenum oxide
4.     The electricity consuming : 280kwh
5.     End gas collection more than 99.5%
