Types of used asphalt plants

An asphalt mixing plant is a machine used to produce asphalt by mixing sand, aggregates, mineral fillers, and bitumen. The asphalt is then used to pave roads, parking lots, and driveways. The used asphalt plant comes in different types, which are usually classified based on the production process and the mode of production.

• Based on the production process

An asphalt mixing plant is categorized into two based on the production process. They are batch mixing plants and continuous mixing plants. The features and working principles of each plant have been explained in the paragraph above.

• Based on the mode of production

Asphalt plants can also be classified based on the mode of production. They are stationary asphalt plants and mobile asphalt plants. Stationary asphalt plants are fixed installations that are suitable for long-term construction projects that require large volumes of asphalt production. The stationary asphalt plant has characteristics like high production capacity, which usually ranges from 40 tons per hour to 320 tons per hour or even more. It also has a wide range of models and configurations to choose from, which include drum mix, batch mix, etc. The stationary asphalt plant is also known for its modular design, which makes it easy to install, transport, and set up.

On the other hand, mobile asphalt plants are portable units that can be easily transported from one location to another. They are ideal for temporary construction projects, such as road maintenance, repair, or small-scale paving jobs. Mobile asphalt plants are quite flexible and can quickly be set up and disassembled. They are also known for their compact design, which makes them suitable for working in confined spaces or remote locations. Furthermore, mobile asphalt plants are usually cost-effective options for businesses with lower production demands or those that require flexible production capabilities. They are also easy to operate and maintain.

Specifications and maintenance of used asphalt plants

There are many design specifications for used asphalt plants. The following are some of the main specifications related to capacity and fuel types.

• Capacity

Small asphalt plants are usually less than 60 tons per hour. They are suitable for small construction projects. The medium-sized asphalt plant can produce between 60 and 160 tons of asphalt per hour. The medium-sized asphalt plant is suitable for medium-sized construction projects. Large asphalt plants can produce more than 160 tons of asphalt per hour. Large asphalt plants are usually used for large-scale construction projects.

• Fuel type

Asphalt plants usually use diesel, heavy oil, coal, or natural gas as fuel. Coal-fired asphalt plants are popular. They have a multi-purpose furnace that can dry and heat the aggregate. Multi-purpose furnaces reduce the production cost of using asphalt plants.

With the right maintenance and regular inspection, a used asphalt plant can operate for decades. The following are some of the main maintenance tips for used asphalt plants.

• Regular lubrication and cleaning

The asphalt plant has many moving parts. Regular lubrication can ensure that each part of the asphalt plant can work normally. Keeping the asphalt plant clean can avoid the accumulation of dust and dirt. Regular cleaning can avoid potential operational problems due to dirt and dust build-up.

• Regular inspection

Regular inspection of all parts of the asphalt plant can find problems in time. It can also avoid potential operational problems and security risks.

• Asphalt plant parts replacement

Asphalt mixing plants have many wearing parts. The wearing parts will be worn after long-term operation. Regular replacement of the wearing parts can ensure the normal operation of the asphalt plant. It can also ensure the quality of the asphalt production.

• Electrical system maintenance

Asphalt plants have complex electrical systems. The electrical system is the core component of the asphalt plant. Regular maintenance of the electrical system can avoid the occurrence of electrical faults. It can ensure the normal operation of the asphalt plant.

Usage scenarios of used asphalt plants

Asphalt is used to pave roads and is an essential component of the modern road construction industry. The demand for asphalt will continue to grow as governments allocate funds for infrastructure development. Asphalt plants can be used in a variety of applications, including the following:

• Public infrastructure

Asphalt is used to build highways, bridges, and municipal road infrastructure. Asphalt plants can produce large volumes of asphalt to meet the needs of high-traffic municipal and highway systems, which may be an essential part of the infrastructure.

• Commercial construction

Asphalt is used in commercial construction projects, such as parking lots, shopping center driveways, and industrial facility roadways. Asphalt plants can produce various types of asphalt mixes suitable for different commercial construction needs.

• Residential construction

Asphalt is an essential material for residential construction. It can be used to pave driveways, sidewalks, and private roads. Asphalt plants with the appropriate production capacity and flexibility can meet the demand for asphalt in residential construction.

• Specialty applications

Asphalt plants can produce special types of asphalt mixtures, such as permeable asphalt, which allows water to flow through the material and into the ground, reducing stormwater runoff and filtering pollutants. Another option is colored asphalt, which offers an aesthetically pleasing alternative to traditional asphalt pavement. In addition, asphalt plants can produce rubberized asphalt by adding recycled rubber polymer or crumb rubber to the asphalt mixture, improving the durability and performance of the asphalt.

How to choose used asphalt plants

When buying a used asphalt plant for sale, it is crucial to consider a number of factors to ensure that the investment is a wise one and that the plant will meet the user's needs.

• Assess the capacity

The first thing to consider is the plant's capacity so the asphalt it produces matches the project sizes. Smaller plants produce around 40-80t/h, while medium-sized ones yield 80-240t/h. Larger plants can make 240-400t/h. It is also important to think about how much asphalt will be needed daily. For example, repairing a road only requires 50t of asphalt a day, while constructing a highway calls for 200t each day. It may be a good idea to choose a plant with a higher capacity than currently needed so it can handle more significant projects later on. This is important if the owner plans to expand their business and take on more work in the future. Selecting a higher capacity plant now will save the cost of buying another one later.

• Consider the type of plant

The next consideration is the kind of asphalt plant required. There are two main types of plants: drum mix and batch mix.

Drum mix plants continuously produce asphalt and are a better option for larger projects. They are more appropriate for roads and highways. Batch mix plants make asphalt in batches and are better for smaller projects where the kind of asphalt required changes frequently. They are more suitable for repairing roads and parking lots. It is crucial to ensure the plant chosen matches the type and scale of the project.

• Examine the age and condition

It is important to check the age and condition of the asphalt plant. The newer the plant, the more advanced its technology is, and the more efficient it will be. Newer plants also have lower operating costs. It is important to inspect the plant thoroughly, look for signs of wear and tear, and ensure that it has been well maintained. It is also a good idea to get an expert to assess the plant before purchasing it to ensure it is in good working order.

Q&A

Q1 What is the difference between buying a new and a used asphalt plant?

A1. Used asphalt plants for sale are more affordable than new models. The main difference is the condition. New machines can handle larger jobs and more production.
