A mobile asphalt plant is an important tool in public works. Without it, it would be impossible for contractors to fill potholes and do other work that needs asphalt. But how is a mobile asphalt plant different from a stationary asphalt batching plant for sale? To answer the question, let’s first take a look at the different parts of a stationary one.
Non-mobile asphalt plants are composed of different parts, with each being a system on its own. There’s a drying system, a gas or oil burner, dust collection system, mixing system, and intelligent control system. A proper mobile plant needs to have all those parts while being portable.
If you search for it online, you will see that there are many different manufacturers of mobile asphalt concrete mixing plant. How do you choose where to buy from? For us, it’s a combination of different factors.
The first factor you need to consider is the capacity. Most people associate mobility with a lowered capacity, however, the truth is that there are units that have an output of 30, 60, and 90 tons. Another factor to consider is if the plant is one continuous wheeled unit, or if the different parts are mounted on different chassis. A truly mobile plant must be mounted on a single chassis that can be towed by a large truck.
The next item you need to consider are the components. The must-have features are the following: automatic burner, dryer, inclined vibrating screen, hot stone elevator, twin-compartment feed hopper, load cell weighing system, primary dust cyclones, twin-shaft paddle mixer, and full PLC controls.
The last but certainly not the least factor you need to is the setup time and the ease with which the plant can be laid out. Check with the asphalt plant manufacturers how long it takes for the mobile plant to set up and be operational. In general, though, having the screening and mixing section as well as the hot stone elevator already in the plant chassis means you can set up the plant and operate it within minutes.
There are mobile plants out there that need a foundation, however, there are also those that have their units stand on legs with support basis, ensuring adequate stability.
If you are particular about plant energy cost, you need to find a mobile unit that has an exhaust fan with variable speed control.
Before buying, make sure you look at the specs. Schedule an inspection. Of course, if you are in the United States and the seller has no offices in the country, you might need to hire someone in China to inspect the unit for you. Of course, there is always the option of a virtual inspection, which works a lot like a virtual tour.
