Rotary Furnaces use oxy-fuel burners to optimize cost, productivity and environmental benefits. A rotary furnace includes a drum and a frame supporting the drum for rotation about a nominally horizontal rotational axis. The rotary furnace is a long sloping tube, tilted back for charging & firing and tilted forward for slag and molten metal discharge.
Rotary hammers uses a special gear mechanism that delivers a strong, pulsing impact force to the drill bit. Most models can be switched into a hammer without rotation mode that drives a special chisel with a rapid back-and -forth action. The rotary hammers can be used when one need to drill big holes in concrete or do light demolition work on a brick path or patio.
