One kind is large rotary slow drum dryer. For example, a cement plant uses a roller dryer for drying chalk soil with 16.5 percent water, and feeding granularity is 10 mm. During the process of drying, material particles are grinded to great extent. The specification of dryer machine is 5.9×45m, rotate speed 2.lr/min. The materials coming out of dryer machine are grinded in single-chamber mill. When they are not dried, in order to guarantee the operation condition that electric dust collector needs to blow water into dryer machine, at the moment, dryer machine is like a Humidifier tower.

When the materials in cement powder system contain much water and own big cohesiveness, and it is difficult to deal with it by way of drying and powder processing, and we can prebake the materials or part of materials in dryer machine, then send them into the system of drying and powder. The process is good for the process of wet and viscous materials, at the same time, it can reduce the power consumption of drying high water-contained materials. but the process is complicated, and the prebaked materials need to middle storage.

The difference between the process and above drying and grinding system is that increasing a set of single dryer machine. So I mainly state the conditions of dryer machine.

The common rotary dryer machine needs no introduction; I mainly introduce two advanced machines that are used to prebake.

Another kind is a small and rapid drum dryer. There is a Hollow shaft in the feed port, and a bearing on the other side. It adopts centre drive. The rotate speed is similar to that of mill. Materials and air adopt concurrent way. The machine has high production and occupies fewer lands.

Taking advantage of tha waste gaas from pre heater and the gas from cooling machine, we set a Cowper stove. The exhausted air quantity of coming out of dryer machine and entering into cottrell is 620000kj?h, and the temperature of waste gas is 110 degrees, and the evaporative water is 47t?h, and heat consumption per unit is 4773kj/kgH20

As the professional manufacturer of complete sets of mining machinery, such as rotary dryers, jaw crusher, Henan Hongxing is always doing the best in products and service.
