Description

Interlayer-free double-layer roller kiln lepidolite roasting production line

Technical Field

The utility model relates to the technical field of roller kilns, in particular to a lepidolite production line for baking a double-layer roller kiln without an interlayer.

Background

The roller kiln is a continuously firing kiln, and is a tunnel kiln taking a rotating roller as a green body carrying tool. When the roller kiln is used, products are placed on a plurality of horizontal refractory rollers with very dense intervals, and the products are conveyed from the kiln head to the kiln tail by virtue of the rotation of the rollers, so that the problem of low efficiency in the traditional kiln car conveying is solved. However, the existing double-layer roller kiln has the defects that the internal space of the kiln body is small due to the existence of the middle interlayer, the smoke circulation is not facilitated, the temperature rise speed of the internal temperature of the kiln body is low, and the production efficiency is not facilitated to be improved.
