Six Major Components of ZK Preheater in Lime Plant

Preheater in lime plant is a device mainly used to preheat material in the rotary kiln, The main characteristic is that the structure is reasonable, the automation level of heat transmission is high. Preheater in lime plant mainly consists of six parts, The ZK engineer explain the six parts in detail.
1 The upper part of the feeding system: It mainly includs the upper hopper, feeding tube, The material feeding mode and the structure can guarantee the safety sealing of the feeding material in the preheater body. Outside cold air can not enter into preheater, and continuous or intermittent feeding can be achieved with the aid of a bar.
2 Preheater body: It is the most important part to ensure the material to preheat 900℃, which is composed of a preheating chamber, a suspension device and a refractory lining (which does not belong to the design scope and manufacture of the equipment and other parts). Most of this parts are metal, parts of the material of the select heat resistant steel which can work at high temperature 1000~1100℃ according to the needs. In addition, the refractory lining structure design novelty, sealing performance is good and it can ensure material in preheater evenly preheated and achieve preheating temperature.
3 Pushing device: It includs frame and connecting parts.
4 Hydraulic system: It mainly includs oil tank, oil pump, motor, solenoid valve, hydraulic oil pipe, etc, its main role is to control the feeding device, to complete the push action.
5 The lower part of the feed chamber: It includs chute, feeding chamber body, feeding spout, its main role is to preheat the material into rotary kiln calcined within.
6 Frame: It mainly includes the column and beam, the main effect is carrying preheater of upper structure.
ZK preheater in lime plant has the characteristics of reasonable structure, thermal efficiency and high level of automation. It can be matched with the lime kiln, preheating limestone or dolomite as raw material. It has been widely used in the industry and obtain a high degree of user evaluation.
