The DRAG or SCRAPER EVACUATORS are used for the transport of small or dusty swarf as for example, from milling or grinding brass, cast iron or steel.
The transport occurs through flights that push the swarf by scraping the bottom of the conveyor and that are moved by a double side chain on rollers.
The following models can be manufactured:
- TVM: horizontal loading
- TVMS: horizontal loading plane and inclined lifting section
- TVMSS horizontal loading, inclined lifting with respect to the support surface and horizontal unloading section
The transport of swarf with this technology can be either dry or with coolant usually contained in a tank integrated with the conveyor itself. However it should be noted that, in the presence of oil, the conveyor in question causes significant dispersion of the coolant and thus it is preferable to equip it with a timing system so that the oil present in the swarf has enough time to flow down the ramp into the tank.
The scraper conveyor can be integrated with filtration systems of the most diverse types according to the work performed and materials processed.
TVMSS drag conveyor outside that receives chips from a centralised plant and conducts it to the silo for storage.INFORMATION REQUEST
