Four Been Feeder

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. In this way, a corresponding cold feed recipe is generated on the collecting belt. The material is then transported to the dryer drum via this collecting belt.

What Are the Different Grades of Concrete?

Concrete grades are determined by concrete's compressive strength 28 days after it has been poured. The strength is measured in psi, or pounds per square inch. The greater the psi rating on a mix of concrete, the stronger the concrete will be after it has been poured and set.

Dust collection system

The flue gas produced in the dryer drum and other exhaust air from the production process are extracted under vacuum and cleaned in the fabric filter. The flue gas is fed to the pre-separator of the filter together with the water vapour. The coarse particles of exhaust gas are separated in this pre-separator via deflection and by slowing down the flow speed. This coarse filler is fed directly back into the mixing process via screw conveyor. The fine fraction of exhaust gas, known as fine filler, is cleaned in the actual filter housing. The filter cloth gradually becomes clogged with dust particles, so it is periodically deducted by a scavenging air fan. The fine filler generated is collected In the dust collecting trough beneath the filter housing and forwarded via a screw conveyor installed in the trough and subsequently deposited in the reclaimed filler silo.

Screening and mixing tower

The actual mixing process takes place in the screening and mixing tower. The materials described in the upstream process arrive at the mixing tower screen via a hot stone elevator. The hot aggregate material is uniformly supplied to the screen’s screening decks. The screen is activated via two unbalance motors, stimulating the screen unit, and thus the screens, to vibrate vertically. The input material is thus divided into the individual fractions and separated according to grain size, stocked in the respective compartments of the hot bin section below.

Mixing and weighing section

The mixing and weighing section is one of the core elements of an asphalt mixing plant. This is where the actual mixing process takes place. From the hot bin section the hot material, stocked according to grain size, is dispensed into the aggregate weigh hopper below corresponding to the mixing recipe. The aggregate weigh hopper is mounted on load cells to facilitate the weighing. The individual fractions are weighed sequentially, i.e. the discharge doors open consecutively and dispense the preset quantity of the respective grain into the aggregate weigh hopper. The weighing of the bitumen and the filler is carried out in parallel to the weighing of the aggregate material in the aggregate weigh hopper. The bitumen is weighed in the bitumen weigh hopper and dispensed into the mixer. The required filler is weighed in the filler weigh hopper, which is mounted on load cells, and delivered into the mixer via an inlet screw conveyor.

Filler silo

Both the filler reclaimed from the plant and the imported filler are stored in a filler silo. Only the reclaimed filler is necessary for the basic function of an asphalt mixing plant. There is also the option of storing and using imported filler (foreign filler). The filler then arrives at the mixing tower for further processing via a filler elevator and a screw conveyor.

Bitumen system

The bitumen binder is a core component of the asphalt. The different types of bitumen, tailored to its relevant intended use, are stored separately in appropriate thermally-insulated bitumen tanks. These are heated in order to maintain the required temperature of the bitumen, approx. 160 – 180 °C. These days’ bitumen tanks are heated almost exclusively via electricity, with a feasible alternative being tanks also heated by thermal oil. This means that the energy from the hot thermal oil is transferred to the bitumen via heat exchangers. The hot bitumen is removed from the tanks via a pump and conducted to the bitumen weigh hopper via heated and insulated pipelines. The tanks are filled by tanker lorry via a fill pump, through pipelines into the respective tank.

Command cabin

A command cabin for operating personnel is available to control the processes of an asphalt mixing plant. The operating menu for the entire mixing plant is installed in this cabin. From here, all drives can be started in manual mode. Here, all data required for the mixing process is collated and displayed. As well as managing the required recipes and monitoring or implementing the mixing process, operating personnel can also control.
