The hot mix elevator is used to transport the hot aggregate from the drum dryer to the vibrating screen at the top of the mixing tower.
High strength double roller plate chain elevator is a mostly common elevator in modern hot-mix asphalt technology. It is usually equipped with anti-reverse device to prevent accidents due to sudden blackout. Air duct and vent at head and bottom to eliminate negative pressure and dust overflow. Low noise improves working environment for operators.
It is mainly composed of following parts:
Upper section: it consists of upper case, hood and sprocket wheels.
Bottom section: it consists of bottom case and tension sprocket. The screw and spring is to control the chain hoisting. For one thing, it can be adjust the loose chain according to the wear condition; for another, it can buffer addition stress resulted from impact. The sprocket rim is dismantled for maintenance and replacement.
Middle section: it is a standard sectional case used to support, protect and seal.
Driving unit: it is an integrated driving unit with bevel gear reducer motor (brake).
Moving unit: The roller chain is high tensile chain made of high quality low carbon alloy structural steel, and hoppers are installed at same interval onto the roller chain.
