Pedrail conveyor system	PLC Control System

★ The furnace body is made of steel structure, and the liner is made of light heat resistant brick. Preheating furnace has the characteristics of low thermal inertia. When start-stop furnace, it can greatly reduce absorbing and releasing heat time of the furnace refractory material. Furnace body is light weight and simple maintenance. New charging raw materials can get the smoke preheating firstly, then gradually heated by flame and the thermal efficiency can reach 70%.
★ The fuel gas combustion system including burner, gas valve group, fan, etc. Burner is automatic continuous proportional control burner. Automatic ignition, flame-off protection, automatic control program. Temperature is controlled in ± 5℃。
★ chain wheel pedrail type conveyor system is domestic most advanced form, the pedrail is chain plate combination mesh belt, the material is high temperature resistant and non-deforming.
★ The control system adopts PLC and touch screen,pedrail speed is adjustable by variable frequency and with a rotary encoder to show speed.
