Products Description
Hollow coal rod machine (also called coal rod extruder) is a molding machine that fully integrates raw materials (powdered materials such as blue carbon powder, coal powder, coke powder, charcoal powder, etc.) with adhesives and compresses them into a certain shape. Diversified molds, different mold styles, available for selection, and can also be customized. Coal rod machine is also called coal rod extruder, coal powder rod making machine, and charcoal powder molding machine. It is a machine that extrude powdered materials into rod-shaped solid firewood rods with a center hole through a high temperature and high pressure process under the condition of adding any binder.

Working Principle
The charcoal powder molding machine is a machine that makes powdered raw coal into strip blocks of different shapes. Its working principle is: the motor transmits power to the transmission through the V-belt, and the transmission output shaft transmits power to the propulsion shaft through the floating coupling. The propulsion on the propulsion shaft pushes the coal material through the forming die head to produce high-pressure coal rods.

Products Features
1. The charcoal powder molding machine has a large feed screw lead, fast feed, small propulsion screw lead, and power saving.
2. The shaft seat and the cylinder body are rigidly connected, with high concentricity, anti-thrust and stable machine.
3. The part to be sealed adopts a fault structure, and the dirt leaks from the fault.
4. V-belt transmission, stable operation, low noise, and overload protection.
5. The charcoal powder molding machine head and the cylinder body are connected with a clamping ring structure and a bolt structure, which can be selected according to the needs of the user.
