spiral around the burner kettle 60 to eliminate hotspots from the burner box 62 hto circulation pump 40 circulates hto to each material pump 36 38 in order provide elevated heat to the material pumps 36 38 to keep the asphalt in a hot molten state for application the return 108 from hto circulation pump 42 is plumbed from the burner box 62 area of the burner kettle 60 thereby pulling hto through the system and eliminating hotspot areas loading the burner kettle 60 with product is accomplished by means of a hatch 61 on the roof 63 of the burner kettle 60 the hatches 61 will be on the top at an angle where the material can be loaded on the hatch 61 when the hatch lid 65 is closed the asphalt material enters the burner kettle 60 which will reduce splash back to the operator alternatively a conveyor system not shown known to the art may be attached to the apparatus 10 for conveying the hardened asphalt block from a storage area directly to hatch 61 for placement into the heat diffusion column 110 of the burner box the conveyor for loading asphalt blocks is typically hydraulically controlled a conveyor will allow transfer of raw materials from a supply truck to the hatch 61 on the kettle barrel 60 the asphalt will be directed from the inline slots 140 through pipes 144 preferably two inch pipes to material supply pumps 36 38 known to the art the material supply pumps 36 38 are helical gear pumps with a jacketed housing for hto to heat the pumps 36 38 the.
