Background

In the field of sintering, the uniform mixing of materials is an important processing procedure. In the sintering production, the raw materials for sintering such as iron ore, flux and fuel need to be uniformly mixed and granulated by a mixer, and then the mixture is distributed on a sintering machine for sintering. The uniform mixing and granulation of the sintering raw materials are generally completed by a cylinder mixer operation. The mixing operation is divided into primary mixing and secondary mixing. The primary mixing is carried out by adopting a primary cylinder mixer, and the primary mixing is mainly used for uniformly mixing various sintering raw materials and adjusting the moisture of the materials; the secondary mixing is carried out by adopting a secondary cylinder mixer, and the main function is granulation.
