Hot Mix Plant: A Comprehensive Overview

Asphalt roads ensure smooth travel. Everybody wants roads that are free of potholes. The hot mix plant is a crucial equipment required to make this happen. But it can be difficult to understand and select the best one for you. However, we’ll make sure that it becomes easy for you to understand so you can choose the hot mix plant that best meets your requirements.

After reading this article, you will understand what a hot mix plant is, as well as its types, applications, and advantages.

Before we dig deeper into the details, let us first define hot mix plant.

What is a Hot Mix Plant?

A Hot Mix Plant, also known as an Asphalt drum mix plant is equipment used for road construction. It helps to create a mixture of asphalt, concrete, aggregate, and filler into a uniform mixture. The same mixture is then heated to the required temperature to create a long-lasting paving material for a road.

Types of Hot Mix Plant

Road Manufacturing Construction equipment companies make hot mix plants in 5 types:

Batch Mix Plant:

A batch-type hot mix plant is the best choice for road construction projects because it is easy to install and produces top-quality hot mix.

How Batch Mix Plant work?

• It heat aggregates and then mix it with bitumen in batches

Benefits:

• Good choice for medium to large projects
• Offers flexibility and precision
• Consist quality

Design: 

• Batch-type plants are containerized.
• Don’t require any civil foundation.
• They can be installed within a few days and can be used anywhere.

Applications: 

• Suitable for high-grade highway construction and municipal road projects.

Capacity:

• Batch-type hot mix plant can have a capacity of 40-240 tons per hour (TPH)

Drum Type Hot Mix Plant

The drum-type plants mix asphalt, concrete, and other materials to produce hot-mix asphalt for road construction projects.

How Drum Type Hot Mix Plant works?

• This plant continuously heats aggregate in a drum, then it gets mixed with bitumen and filler material in that same drum.

Benefits:

• Lower initial cost of investment
• Use less energy, because there is no need to heat every batch.
• Requires less space to install

Design:

•  The basic layout of this equipment is simple.
• They are available in parallel flow type or counter flow type.

Application:

• It is well suited for small to medium-scale projects because it produce a uniform output of hot mix asphalt.

Capacity:

• It depends on the size of the project, but most plants have a capacity of 40-160 tons per hour (TPH)

Mobile Hot Mix Plant:

These plants provide portable asphalt production facilities to manufacture hot mix asphalt for road construction and maintenance.

How Mobile Hot Mix Plant works?

• Aggregates are filled in the plant and then it is heated in a rotating drum.
• Heated aggregates are then mixed with liquid asphalt, widely known as Bitumen.
• The final asphalt is stored before getting loaded in trucks.

Benefits:

• It eases the transportation facility
• It is proven to be flexible for smaller or remote projects
• Quick to setup

Design

It is placed on skids or trailers for easy transport

Applications:

• Road construction or repair
• Highway maintenance
• Airport runway construction
• Parking lot paving

Capacity:

• Typical production capacity ranges from 60-200 tons per hour (TPH). Larger units can produce up to 400 TPH

Stationary Hot Mix Plant

This plant helps with asphalt production facilities for long-term operation at a fixed location. It is not intended to move.

How Stationary Hot Mix Plant works?

• Aggregates are first stored in large stockpiles and then filled in cold feed bins.
• For the heating and moisture removal process, it is transferred to a dryer drum

Benefits:

• Highest production capacity among all mixed hot plant types
• Advanced control system
• Lower operating cost

Design:

• Permanent structure
• Large storage area
• Multiple storage silos

Applications:

• Large-scale commercial and industrial projects
• Big highway construction projects
• Centralized supply for a wide geographic area

Capacity:

• Typical range:200-600 tons per hour
• Large plants: Upto 88 TPH

Semi- Stationary Hot Mix Plant

This plant lies between fully mobile and completely stationary hot mix plants. Designed to move less as compared to mobile plants but a little more easily than stationary ones.

How Semi- Stationary Hot Mix Plant works?

• Aggregates are filled into bins
• Materials are transferred in a dryer drum for heating
• The finished asphalt mix is stored before being loaded in trucks.

Benefits:

• Higher production capacity
• Provide stable operation
• Easier to set than stationary plants

Design:

• Compatible components for easier transport facility

Applications:

• Large-scale road construction
• Airport runways
• Industrial and commercial paving projects

Capacity:

• Typical range:160-40
• Larger units: up to 600 TPH

5 steps to choose the best Asphalt Mix Plant:

Step 1: Determine the use and type of Asphalt Mix Plant

1. For large-scale and high-grade new road- Asphalt batch mix plant.
2. For a road project that has mileage and a narrow road surface- A stationary mix plant or drum mix plant is suitable.
3. For fixing some small pits on the road- Drum mix plant
4. For hilly area road construction project – Asphalt drum mix plant or mobile plant

Step 2: Determine the capacity of the Asphalt Mix Plant

Determine the average output of the mixing plant per hour, taking into account the project’s scale.

A mixing plant with a 50 or 60 TPH capacity should be selected if the calculation yields a 40-tonne result.

 A plant with a 400 TPH capacity is the ideal option if the production needs to reach 3,000 tons in 8 working hours.

 Operating at 80-90% capacity for the majority of the time is what defines an excellent asphalt mixing facility.

Step 3: Determine if the plant can meet local, standard, and environmental road construction energy-saving requirements

Different countries have different specifications, according to which the plant needs to be adjusted. If it fails to meet the standards, it may bear the risk of getting the project shut down. Hence it is necessary to choose an environmentally-friendly hot mix plant.

Step 4: Determine the price range:

The budget determines the capacity and type of the asphalt mix plant. You must consider cost-effectiveness and reach out to different road construction equipment manufacturers.

Step 5: Determine the after-sale services of manufacturers

It’s essential that they provide emergency breakdown service availability of 24/7 support. Do ask about typical response time in emergency situations. A manufacturer that provides complete support after sale must be highly prioritized.
