Eliminates Infrastructure Requirement FTC-200 Tracked Cone Crusher does not require an extra infrastructure as a production method, it can be moved by remote control and adapts to all difficult terrain conditions. Belt Feeder The Belt Feeder is the system in charge of quickly sending the loaded products to the crusher for the crushing process.It has a belt feeder motor protection system that gains mobility thanks to 2 motors. Thanks to this system, malfunctions that may occur as a result of overheating are prevented.The working intensity of the Belt Feeder and the crusher is coupled with the automation system. This feature works in two steps. Step 1: If the density of the crushed product in the crusher is high, the amperage of the crusher rises and this rise is detected by the automation system, the bunker transfer stops.It prevents product accumulation in the crusher feeding chute. This feature prevents the crusher from being worn out. Step 2: If the density of the crushed product in the crusher is low, the amperage of the crusher decreases. This decrease is detected by the automation system and bunker transfer increases. The feeding hopper delivers the products to the crusher faster. This feature keeps the production capacity at the maximum level. Cone Crusher Cone crushers are the crusher of FTC-200 Tracked Crushing Plant that can easily crush hard stones.The power transferred from the engine to the gear shaft is sent to the hub with gears.Thanks to the core and concave inside the crusher, it crushes the stones and breaks them into pieces.
