How does LB2000 asphalt batch plant work?
• preliminary batching of wet rock materials in the feeder unit;
• drying and heating rock materials up to the operating temperature in the drying drum and their feed to the screen of the mixing unit;
• sorting heated rock materials by fractions, batching and their delivery to the mixer;
• three-stage de-dusting the smoke gases going out of the drying drum in the preliminary cleaning system, cyclones of dry de-dusting and in a wet dust catcherscrubber (efficiency of dust catching makes 99.7-99.85% depending on the type of applied materials) or cleaning in bag filters (in this case dust emissions do not exceed 20mg/m3, which is 7 times as efficient as the combined de-dusting system);
• use of the caught dust by its delivery to the dust compartment of the mixer unit bin or to the dust unit bin;
• acceptance of mineral powder from cement trucks, its batching and delivery into the mixer;
• acceptance of bitumen from bitumen truck (or bitumen storehouse), its temporary storage and heating in bitumen tanks up to the operating temperature, batching and feed to the mixer;
• mixture delivery to the dump-truck or its feed by a skip hoist to the ready mixture bin.
