黑色混合料拌和机是修筑黑色路面重要设备之一。目前国内外拌和机,对石料的干燥、加热及沥青的加热、保温大多以热油做热源,生产一吨120℃混合料,用5～7公斤柴油。以每小时产量为25吨的拌和机为例,施工一个台班要烧掉一吨多燃油。这不仅增加了混合料的成本,浪费能源,且这类拌和机结构复杂,操作麻烦,造价较贵。长期以来,不少单位对黑色路面的铺筑、维修、养护只好采用撒铺法人工拌合,用混凝土拌和机来应付。路面质量不好,且劳动强度大。
Black mixer is one of the important equipment for building black pavement. Currently domestic and foreign mixing machine, the drying of stone, heating and asphalt heating, insulation mostly hot oil as a heat source to produce a ton of 120 ℃ mixture, with 5 to 7 kg of diesel. For example, a mixer with a capacity of 25 tons per hour will burn up to one ton of fuel per station. This not only increases the cost of the mixture, wasting energy, and the structure of such a mixer is complicated, the operation is troublesome, and the cost is more expensive. For a long time, many units paved the black pavement, maintenance, conservation had to use sprinkling artificial mixing process, with a concrete mixer to deal with. Pavement quality is poor, and labor-intensive.
