Gypsum rotary kiln is a new type of environmental protection equipment and its main drive system adopts the model of AC variable frequency speed control technology. Compared with the traditional electromagnetic speed regulation, DC speed control, gypsum rotary kiln has the advantages of energy-saving, environmental protection, wide speed range, high efficiency, high speed precision and smooth operation.

As a well-known rotary kiln for gypsum manufacturers, ZK absorb and refer to the domestic and foreign types of rotary kiln developed a series of patent technique of gypsum rotary kiln and non-standard proprietary equipment, achieving a high efficiency and energy saving automatic production and environmental protection standards.

1 To create the perfect process, leading the industry pioneer

Gypsum rotary kiln made in ZK is adopted the vertical preheater with advanced structure and low pressure loss. This type gypsum rotary kiln can save 40% fuel and rotary kiln typical capacity can increase by 30%. And it can recover heat in the exhaust gas, which is conducive to the flue gas dust removal, emission targets to 30mg / m³.

2 High quality, high yield, environmental protection and energy saving

Gypsum rotary kiln of the environmental protection and energy saving mixed burning can achieve the three thermal processes that preheating zone, calcination zone, the cooling zone with a reasonable distribution, so that full use of fuel heat. Material from the top of the preheater silo into the preheater body, while the rotary kiln incoming high-temperature flue gas preheat the material above 1000 degrees centigrade, so that the partial decomposition of limestone. And then the hydraulic push rod push material in turn into the rotary kiln outlet, after rotary kiln high temperature calcination and then discharged into the cooler, through the fan blowing cold air cooling, the material cooled to ambient temperature 60 degrees centigrade below the discharge cooler. The air blown in by the cooler enters the rotary kiln to be burned as secondary air. In the course of all operations are closed and automated, flue gas discharged by the pipeline and through the dust to achieve pollution-free emissions. It not only can achieve high quality and high yield, but also can save energy and achieve environmental protection.

3 Supporting dust removal equipment, building a green project

The high temperature flue gas generated by the rotary kiln reduce to below 250 degrees centigrade after heat exchange with the gypsum in the preheater. Then the cyclone dust collector is used to collect the dust, and the large particles are collected, and then the rest of gas is into the bag type dust collector. High temperature gas after dust removal is discharged into the atmosphere, emissions of dust concentration is less than 30mg/m³, which fully meet the modern environmental protection requirements. In the precipitator inlet is also provided with a cold air control system for the protection of dust collector.

ZK gypsum rotary kiln process is easily arranged. You can configure vertical preheater in the kiln outlet, which can make full use of the high temperature flue gas in the rotary kiln calcination to preheat the gypsum from the room temperature to the initial decomposition state. Also vertical cooler can be arranged in the kiln head to make the high-temperature lime quench to improve product activity and be convenient for transportation and storage.
