1. Project Overview

The Henan Zinc Oxide Rotary Kiln Project, a shining star in the industry, features a core piece of equipment: a φ3.6×60m rotary kiln. Since the project was signed in September 2023, it has quickly become a leader in the field of zinc-bearing material recycling. This rotary kiln is mainly used for the reduction and volatilization recovery of valuable metals such as zinc and lead from zinc-bearing materials. It boasts a series of advantages, including excellent calcination effects, high capacity, high operation rate, and low energy consumption.

2. Product Advantages

The zinc oxide rotary kiln stands out among many competitors primarily due to its unique product advantages.

·       Support Roller Device: The rolling bearing design effectively reduces friction, making the equipment run more smoothly. The bearing seat uses circulating water cooling technology to quickly lower the bearing temperature and extend its service life.

·       Transmission Part: Equipped with a variable frequency motor, the speed can be adjusted at any time according to production needs. This design not only enhances the flexibility of the equipment but also reduces energy consumption, achieving the goal of energy-saving and environmentally friendly production.

·       Auxiliary Drive: Equipped with an auxiliary motor to ensure kiln operation can continue during a main power outage, preventing deformation of the kiln body. Additionally, the application of an electro-hydraulic block brake prevents reverse rotation when the kiln stops, ensuring the safe operation of the equipment.

·       Thrust Roller Device: Utilizing a hydraulic thrust roller design, the hydraulic station provides pressure to push the thrust roller and kiln body up and down. This innovative design achieves fully automated operation without manual intervention, improving production efficiency.

·       Kiln Head and Tail Sealing Device: Adopting a three-layer flexible sealing structure (stainless steel sealing scales + carbon silicon aluminum fiber composite board + stainless steel sealing scales) combined with a labyrinth structure sealing method, effectively reducing air leakage. This design results in excellent sealing performance, higher reliability, longer service life, and easier replacement, significantly lowering maintenance costs.
