Title:
CEMENT-BASED MATERIAL GRANULE HEAT TREATMENT DEVICE COMPRISING SUPPORTING GAS BLOWER DEVICE
Document Type and Number:
Japanese Patent JP2021156464
Kind Code:
A
Abstract:
To solve the problem that, when cement-based material granules are heat-treated using a rotary kiln furnace, the cement-based material granules are easy to be deposited in a rotary drum near directly below a feeder so as to cause clogging.SOLUTION: A supporting gas is intermittently discharged to cement-based material granules transferred from a feeder into a rotary drum. In this way, not only organic matter included in the cement-based material granules can be removed, but also the transfer of the cement-based material granules is promoted by the intermittently discharged supporting gas, and deposition can be suppressed near directly below the feeder.SELECTED DRAWING: Figure 1
