Both bulk quicklime and bulk hydrated lime are transported in pneumatic trucks. These types of trucks use air pressure, generated by equipment on the truck, to blow the product into a silo at the customer location. A truckload of bulk quicklime weighs about 25 tons (50,000 lbs.) A truckload of bulk hydrated lime weighs about 18-25 tons (36,000 to 50,000 lbs).
Bulk quicklime is transported in hoppercars. The quicklime drops from the bottom of the car into a type of unloading system. One type of system has the quicklime drop into a screw and conveyor system where it is transported to the silo. Another unloading system involves the use of an unloading pan that is attached to the opening at the bottom of the car. (There are multiple openings). The quicklime drops into this pan and is then subsequently drawn into the system via vacuum and transported to the silo. A hopper car of lime can be viewed as the equivalent of four trucks and weighs about 100 tons (200,000 lbs).
