A brief introduction to gypsum dryer
With the increase of cement production, the demand for gypsum has increased accordingly. As the rapid growth of the global economy, the industry of gypsum especially the gypsum product will have great developing space, and various kinds of gypsum products and gypsum wall will be developed rapidly.
However, due to the development of traditional ceramics and other special industries related to gypsum, excellent gypsum resource has reduced continuously which makes the exploitation and utilization of gypsum resource be more important.
Therefore, to make sure that the whole gypsum industry can be developed sustainedly, and green, environmental and non-polluting gypsum building materials and products can be more widely used in people's life, the limited gypsum resources must be optimized and reused.
During the process of optimization and reuse of gypsum, industrial equipment such as dryer must be used. Gypsum dryer produced in FTM Machinery is an environmental machine with the features of reliable performance, low fault rate, stable operation, high efficiency and low electricity consumption.
The advantages of gypsum dryer
- Gypsum dryer can be configured with different drying temperature and drying time to achieve automatical drying.
- The rotation of gypsum dryer barrel is more stable with the feature of high degree of automation which can achieve remote control, and the operation is getting more humanized and convenient.
- During the drying process, the contact surface between gypsum and drying medium is getting larger, and the drying efficiency is higher.
- During the drying process, there is no gypsum stuck in the internal surface of the barrel.
- The wearing parts of gypsum have excellent performance with the features of high abrasion-resistance, strong toughness and long lifespan.
The performance and characteristics of gypsum dryer
- Chemical gypsum (flue gas desulfurization gypsum, ardealite, etc) is used to stir-fry into β-hemihydrate gypsum powder.
- The machine guarantees the precision control of drying time and temperature requirements of calcined gypsum powder.
- The outlet of the drying machine is designed reasonably without dust pollution at run time.
The inner structure of gypsum dryer
The gypsum dryer is composed of the cooling device, the feeding device, the roller, the drying kiln, the transmission, the supporting device, the discharging device, the cyclone separator and the induced draft fan, etc.
Working process
- 1The gypsum feeds into the inner layer of the multi-layer drum by feeding machine, to achieve downstream drying. It will be constantly lifted by lifting boards and scattered in spiral type to make a hot exchange, and then, the gypsum will be moved to the middle layer of the drum for counter-current drying.
- 2The gypsum in the middle layer will be constantly lifted by lifting boards and it can both full absorb heat generated by the inner drum layer and the middle drum layer, while extending drying time, so the gypsum can reach its driest state in this process.
- 3The gypsum can move to the outer drum layer from the middle drum layer of gypsum dryer, and gypsum reached the drying effect will be discharged fast along with hot air, while wet gypsum that doesn't meet the drying requirement can't move quickly due to its weight, so wet gypsum can get adequate drying to reach drying effect thus completing the drying process.
The price of gypsum dryer
The factors that affect the price
- The model: There are several models of gypsum dryer in FTM Machinery, and different models have certain differences in the adopted techniques and parameters. Also, gypsum dryer in different models have different capacity, and large gypsum dryer has strong capacity and higher prices; inversely, the smaller has cheaper prices.
- The competitiveness: The competitiveness among gypsum dryer manufacturers also gives influence on the prices. The market with higher competitiveness has lower prices in gypsum dryer; on the contrary, the market with lower competitiveness has higher prices.
- The quality: The quality of gypsum dryer not only affects the drying efficiency of equipment but also influences equipment prices greatly. The equipment with good quality has higher manufacturing costs which make the price higher; on the contrary, equipment of average quality has average efficiency and lower price.
How to choose the gypsum dryer?
- Choose large brand manufacturers so that the equipment quality and after-sales service are more guaranteed.
- Consider the manufacturer's delivery cycle and speed.
- Understand the reputation of the manufacturer and the evaluation of the previous customers.
- Compare and analyze several manufacturers.
