Belt speed	50~300mm/min, Typical work speed is 130~200 mm/min, stepless speed  regulation control with frequency conversion.
Driving system	Drive Control uses the servo system to control the speed by gear box. The speed is adjustable continually
Conveyor device structure	Belt conveyor device: to drive the driving and driven wheel through chain and sprocket wheel, and then generate the friction force by driving wheel and the belt drive the belt running. There is a belt deviation guide device on the both sides at the entrance and exit
Belt cleaning mode	Brush cleaning
	Ultrasonic cleaners

5,Atmosphere system:
 

Firing atmosphere	5 compressed air, each flow can be adjusted, measuring range: 12~120L/min
Exhaust System	Preheating zone have two exhaust stacks

Table 2
No.	Name	Description
A	Entrance curtains	Prevent outside air from entering the furnace
B	Burn off gas inlet	Used for gas supplement of heating zone
C	Exhaust gas inlet	The manual valve on Venturi exhaust tube can be used for adjusting gas flow
D	Firing gas inlet	Used for control gas flow direction and prevent colloid pollution the products
E	Exit curtains	Prevent outside air from entering the furnace
The actual gas flow of each pipe can be displayed by flowmeters.

6,Cooling System

Cooling structure

Stainless steel cooling water jacket, there is cooling fan at the exit table.

7,Security protection:

Emergency Stop Button	two emergency stop buttons at the entrance and exit of the furnace, one for belt and one for power
Alarm instructions	over temperature, thermocouple failure, low gas pressure,low water pressure, low water pressure, belt stop alarm, ignitor alarm and other audible and visual protection

8,Temperature control system

Temperature measuring	use K type thermocouple independent measuring and control on the temperature control point of each zone
Temperature control	use of imported Intelligent temperature controller to control, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions
Control mode	Solid state relay zero cross trigger mode
Over Temperature Alarm	when over temperature occurred in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm.
Computer Control System	Use DCS control system,
	Intelligent temperature controller control, industrial computer monitor
	Friendly human-machine interface, industrial computer can carry out multiple programs saving
	Real-time temperature and alarm record, data saving and printing.
	It also can provide the temperature calibration function in the chamber for adjusting process requirement.
