Working Principle of Spin Flash Drying Equipment:
XSG series rotary flash dryer is a high efficient new type drying equipment with wide accommodation developed and designed on the basis of summarizing the vulcanizing bed, thermal smashing, rotational flow and grading technology. The heated (or dehumidified) air enters into the agitating breaking drying chamber from the bottom of the dryer with a suitable spouting speed to produce a strong cutting, blowing and floating and rotating function to the materials, and then the materials are centrifuged, cut, impacted and rubbed to become micronized, forming larger specific surface area and strengthening the heat transmission of the mass transfer. The large and wet pellet groups are smashed under the action of the agitator at the bottom of the drying chamber and the smaller pellets with less moisture content are brought up by the rotating air flow, dried further during going up and graded.

Characteristics 
Drying sticky materials 
The cone structure in the dryer, washing out of the air flow to the wall and the structure of the agitator determines it can deal with certain sticky materials. 
Drying thermo-sensitive materials 
As the drying time is short, the relative speed between the materials and the hot air is big, and the hottest air does not contact the dried materials directly, it is suitable to treat the thermo-sensitive materials. 
The system eliminates the operation environment pollution under the negative pressure in the operation and it adopts different dust removing mode and materials according to the different raw materials (pulse bag dust catcher, water shower duster, Venturi damp dust remover and so on). 
Low labor intensity 
The feeder and the discharger are made in different forms according to the difference of the materials so as to reach automatically continuously feeding and discharging aims. 
The best power matching 
The blower, the draught Fan, the agitator and the feeder and so on are furnished with the best power according to the different nature of the materials (density, bulk density, viscosity, fineness, primary moisture, final moisture, angle of repose and so on).
 
 
Heating mode and configuration The heater is the equipment of sending heat source for flash drying. Heating of the air can adopt steam heating exchange or steam electric heating (c), hot-air stove indirect heating (a), gas direct heating(b) with coal, oil, gas and so on as the heating fuel. The temperature of the input hot-air can be at 100- 600.
Feeder The feeder is the structure designed according to the different physical nature of the materials and it can send the various wet grade sticky materials continuously into the dryer. Feeding is divided into single screw, double screws, screw with shaft and without shaft and multi-shaft screw and so on. A screwdown gear is added in order to prevent the silo from blocking the material. When sending liquid materials it adopts special feeding mode. 
Main drying machine (drying chamber) The main drying machine assumes round structure. Dispersing blades are equipped in the drying chamber and there is an annular slot at the bottom of the drying chamber. The factors of the shape of the bottom of the drying chamber, annular slot and so on are adjusted with the changes of drying materials. The diameter of the drying chamber can be changed from 250mm to 2750mm and the temperature of the drying chamber can reach as high as 600.
Material collector As the material dried in the drying chamber enters into the collector, the specific weight, fineness and viscosity of the dried powder has close relationship with the selection of the configuration of the collector. Selection of the collector often uses a1 b1 forms and the quality of the material is selected from the angle of antisepsis, heat-resistance and so on. Drying of the material having special physical characteristics in the drying process and requiring special process such as inert gases protection, heat-sensitivity, antistatic behaviour all should adopt the different systematic configuration mode in conformity with the process.

The Escalator Brake include: working brakes, additional brakes and auxiliary brakes. The operating brakes are normally mounted on the high speed shaft of the motor and should be such that the escalator is stopped at a nearly constant speed during the stop operation , And can stay stopped. Work brakes in the course of action should be no intention of delay. The working Brake shall be of a normally closed mechanical-electrical brake which shall be controlled by at least two sets of independent electrical devices which must be produced by means of a guide compression spring or the like. Actuators for escalators usually use block brakes, belt brakes and disc brakes. The brake force of the block brake (brake shoe) is radial and the brake blocks used are in pairs so that the brake pads are balanced with each other and the brake axle is not subjected to bending loads. The components of the block brake are the brake wheel, the brake pad and the high friction coefficient of the pad, the brake arm and the release riveted thereon. When the escalator is stopped, the electromagnetic coil is de-energized, the brake shoe is under the action of the brake spring, hold the brake drum, the escalator stops. Run on the escalator at the same time there is a micro-switch to verify the brake is fully open, in order to protect the brake. This brake is simple to manufacture, easy to manufacture and install.
