Application
Mainly used in Zn pyrometallurgy industry as volatilization kiln and calcine kiln.
Features
(1) High recovery to enrich Zn, Pb, Cd, Fe, etc.
(2) Environment friendly. The chemical property of slag after rotary kiln process is stable, not soluble in water, not volatile;
(3) Easy to operate, performance is reliable.
Parts
Riding Ring or Tyre
Tangential suspension – when the kiln shell is fixed to the kiln tyre all the way around – can be used in both kiln types. Its main function is to distribute the supporting forces along the entire circumference of the kiln. This results in low ovality of the kiln and longer refractory lifetime.Furthermore, kiln alignment is not affected by minor settling of the foundation, making periodical realignment unnecessary. Because the kiln is suspended concentrically inside tangentially suspended tyres, the kiln shell can expand freely, and there is always a gap between the kiln tyre and the kiln, eliminating the need for lubrication as well as wear between tyre and kiln. This completely eliminates the risk of shell constriction and the need for tyre migration monitoring systems. It ensures reliable transmission of drive power under any operating conditions. All parts are also visible with tangential suspension, simplifying both inspection and maintenance.Our kiln uses only tangential suspension to accommodate its higher flexibility. While the 3-base kiln is provided with floating suspension as standard, it can also be fit with tangential suspension. In the 3-base kiln, when using floating suspension of the kiln tyre, loose-fitting blocks are held in place by bushings secured to the kiln shell. This allows easy restorative shimming to take place, lessening maintenance costs.
Roller Chassis
The Roller Chassis of kiln has the appropriate amount of flexibility needed to provide maximum support when spreading the load from kiln to foundation. Our kiln features an advanced support system – a fully flexible, selfaligning solution that follows the movement of the kiln. Supported in tangentially suspended tyres, on selfadjusting rollers, the kiln shell benefits from a support configuration that ensures full contact between roller and tyre. This leads to an even distribution of the load, eliminating the possibility of localized high stress areas. The increased allowable hertz pressure permits the use of smaller support rollers and tyres. This leads to high availability, low maintenance and low operating costs. Due to the more stiff structure of the 3-base kiln, the support can be made in a more simple rigid and semi-rigid design to ensure adequate support.
Internal View
The refractory bricks should be laid to protect the kiln shell. The bricks we used are high aluminium bricks contained Al2O3 more than 70%. This specification brick can make sure the bricks to be against erosion with good physical properties.
