An insulating flight for a dryer incorporates inner and outer plates with insulation between them. The concave surfaces of the inner and outer plates provide a space for the insulation and allow for thermal expansion without stressing the welds between the inner and outer plates.

Dryer with insulating flights

An asphalt plant includes a rotary dryer, a rotary mixer, a conduit for transferring gas from the mixer to the dryer, and a flame arrester in the conduit adjacent to the dryer to prevent a fire from propagating from the dryer back through the conduit.

Asphalt plant including flame arrester

A rotatable drum arrangement, wherein the drum is mounted on support rings such that circumferential expansion and contraction of the drum relative to said support rings does not adversely affect the mounting. In a preferred embodiment, drum blocks are mounted to the drum, and corresponding ring blocks are mounted to the support ring. The side surfaces of adjacent drum blocks and ring blocks support the weight of the drum on the ring. In this arrangement, gaps may be maintained between the drum and support ring that allow for expansion and contraction of the drum. In the preferred embodiment, there is also a drive sprocket mounted on the drum with a sprocket mounting arrangement that also accommodates expansion and contraction of the drum.
