The slinger conveyor belt is an important component in a stationary or mobile drum mix plant. Driven by A. C. motor, aggregates are transferred to drying and mixing unit of the hot mix plant. It is equipped with weigh bridge (Load Cell) for continuous monitoring of weight (tons/hour)
HOT MIX ASPHALT PLANT OPERATIONS An asphalt mixture plant is an assembly of mechanical and electronic equipment where aggregates, recycled materials or other additives are blended, heated, dried and mixed with binder to produce asphalt mixture on a belt conveyor, and/or bucket lines, which carry the aggregates to the dryer. Feeder controls
At an asphalt mixing plant, the aggregate material is stockpiled according to grain size and type. This material is usually loaded into the individual hoppers by a wheel loader. The minerals are dispensed via dosing belts (normally frequency-controlled) onto the collecting belt below, specific to the recipe.
SCALE BELT: The ratio computer is the brains and the scale conveyor is essentially the heart of a drum mix asphalt plant. Under certain conditions, if it is transmitting inaccurate data to the ratio computer, this unit can literally break a company through 'out-of-spec' penalties.

The aggregate is moved down the drum by a combina tion of gravity and the configuration of the flights located inside the drum. As it travels, the aggregate is heated and the moisture removed.
Asphalt Mixing Plants 4 Australian Asphalt Pavement Association – 2010 Figure 2 Diagram of a typical drum mix plant 6 PLANT RECYCLING OF ASPHALT 6.1 GENERAL Plant recycling of asphalt may be by using either hot or cold processes. A detailed account of all asphalt recycling methods may be found in the Austroads Guide to Asphalt Recycling (1997).
These all affect plant operating temperatures, dust types and dust volumes the baghouse experiences. Bags that are commonly found in today’s hot-mix asphalt production world include 14 oz. Nomex, Nomex singed, micro denier, hydro entangled, and P84, for higher temperature applications.
Slinger Conveyor: It is on a strong frame with endless belt. This conveyor transfers the aggregates to the drying drum. Drying Drum: Counter flow design of the drying drum of asphalt mixing plant ensures the best use of burner’s energy and allows maximum fuel savings. Drying drum is fitted with a high efficient and low noise burner is capable

4. Asphalt Plant 4.1. Introduction Asphalt plants heat and dry the aggregate and mix it with the appropriate amount of asphalt cement, in accordance with the project mix design. There are two main types of asphalt plants: batch plants and dryer drum plants. These are briefly described below. Standard Highway Specification 4.01-3.03 requires
Accu-Swipe™ Belt Sampler. The belt sampler simplifies the quality control function at the hot mix asphalt plant. Mounted over the aggregate conveyor it automatically provides representative material samples for laboratory analysis without interrupting production.
The main components of universal drum mix plant are multiple cold aggregate feeder bins, single deck scalping screen, slinger conveyor, rotary drum, burner, load out conveyor, asphalt tank, mineral filler unit, fuel service tank, wet scrubber and control panel.
The hot oil pumping through jacketed lines is the lifeblood of the plant. Step Four: Turn on all conveyor belts including the collector, incline and weigh scale belts. With your 10 steps in sequence to starting up the asphalt plant, you’ll finally look at your screen(s) in the control house to ensure everything is up to the proper
Asphalt binder and hydrated lime are injected into the area between the two drums to mix with the hot aggregates in a zone where there are no hot exhaust gases to harm the liquid asphalt binder.
May 26, 2019· Belt conveyor for 140 TPH asphalt plant. Consist in 4 bins with dossifier belts and main belt conveyor. If you need calcuations, contact me
Mar 12, 2021· Batch type asphalt plant can produce high quality asphalt mixtures in batches, which is suitable for paving high-grade roads, such as highways. The capacity of the batch plant is large, ideal for large and medium-sized projects. Drum mix asphalt plant can continuously produce asphalt mixtures, so it is also called continuous asphalt mixing plant.
typical batch plant is depicted in Figure 5-1; the major plant components are shown in Figure 5-2. The batch plant tower consists of a hot elevator, a screen deck, hot bins, a weigh hopper, an asphalt cement weigh bucket, and a pugmill. The flow of materials in a batch tower is illustrated in Figure 5-3. The aggregate used in the mix is removed
