Ajax concrete mixer

Types of ajax concrete mixers

An ajax concrete mixer mixes and combines raw materials like cement, aggregates, water, etc. According to the mixing method, there are four common types of concrete mixers: a drum mixer, a twin-shaft mixer, a vertical shaft mixer, and an automatic mixer with a pump.

• Drum mixer: A drum mixer features a fixed drum that rotates to mix the concrete ingredients. It is commonly used for large-scale construction projects. Drum mixers can be divided into two rotated types: reverse and continuous rotation. The drum's reverse rotation during the feeding process helps to keep the concrete from being agitated. However, in the discharge process, the drum continues to rotate and agitate the concrete. Continuous rotation is suitable for mixing mass concrete due to the continuous feeding and discharge processes. The drum needs to rotate reversely during the feeding and discharging processes. Reverse rotation is mainly used for site concrete preparation.
• Twin shaft mixer: The twin-shaft mixer has two rotating shafts with a series of paddles that move the concrete mixture in a horizontal direction. It is famous for its efficiency and ability to produce large batches of concrete. Besides, the mixer has a fast mixing time of fewer than 60 seconds. During the mixing process, the shafts and paddles' movements help to make the mixture uniform, improving the overall quality of the final product.
• Vertical shaft mixer: A vertical shaft mixer, also known as a planetary mixer, is a device that uniformly mixes various components, such as cement, sand, gravel, water, and additives, to produce concrete. The motor-driven vertical mixing blades move the mixture upward, then downward through the central concrete bowl. Compared with drum mixers and twin-shaft mixers, vertical shaft mixers consume less energy. Workers can quickly access and clean the mixer.
• Automatic mixer with pump: The mixer with a pump combines mixing and pumping functions into a single equipment. It can automatically feed, mix, and transport materials, achieving continuous mixing and conveying operations. The integrated machine enhances the efficiency of construction processes, simplifies equipment configuration, and reduces labor intensity.

In addition to the above mixers, there are mobile concrete mixer trucks. Mobile concrete mixers are beneficial for small projects with limited space and access to construction sites. The machines can transport, mix, and pour concrete precisely where required. Furthermore, concrete plants are large industrial facilities for producing vast amounts of concrete. The materials are mixed in large drums and transported to construction sites using concrete transit mixer trucks.

Specifications & maintenance of Ajax concrete mixers

Specification of an Ajax concrete mixer may differ depending on the models. The following are some key specifications.

• Mixing capacity: It indicates the volume of wet mixed concrete it can produce. It can range from small mixers with capacities around 0.5 to 3.0 cubic meters to larger industrial mixers that handle higher volumes, sometimes exceeding several cubic meters.
• Power source: The power source of the concrete mixer can be an electric motor or a gasoline/diesel engine. In general, the electric motor provides sufficient power for mixing concrete, especially in urban construction. Gasoline and diesel engines are more applicable in outdoor and rural construction areas. Drivers may also use them in remote areas where electricity is unaccessible.
• Power: It refers to the driving motor of the Ajax concrete mixer, which is usually in kilowatts (kW) or horsepower (hp). The larger the power, the smoother the mixing and discharging process.
• Overall dimensions: It includes length, height, and width. The overall dimensions of a concrete mixer determine its portability and ease of integration into a construction site.
• Weight: The mixer machine's weight impacts its stability during operation and transportation.

Maintenance

• Daily maintenance:It includes cleaning, watering, and lubrication. Regular water flushing prevents concrete from hardening inside the drum. It's also important to clean the water system to avoid bacterial growth. Squeezing a wet rag on the drum surface can reduce the friction and temperature on the surface. Lubricate the oil filling holes, gear wheels, and lubricate the bearings on the fixture.
• Regular maintenance:Regular maintenance includes regularly checking and repairing key parts. It ensures the water system works well and has no leakage. Checking whether the water pump is running at normal speeds can also help. Users should also check the lubricant of reduction gears and bearings and replace them as per requirement. In some cases, lubricant additives may be required to improve the bearing capacity and reduce the wear.

Usage scenarios of Ajax concrete mixers

Due to the popularity of the scalar product concrete mixer, usage scenarios have multiplied in recent years. The following sectors are the most popular business buyers and their end-users:

• Construction industry:

  From small building projects to large-scale infrastructure development, an ajax concrete mixer plays a very important role in the construction industry. Different types of mixers are used according to the needs of the project. For example, a mobile mixer is preferred by a remote construction site that is away from the city. In addition, many ajax cement mixers feature a charging capacity of over 400 liters, making them even more powerful.

• Urban Infrastructure Maintenance:

  Urban infrastructure requires a large amount of concrete, such as road repair and maintenance, water supply and sewage systems, and other projects. Concrete mixer trucks provide a continuous and reliable supply of freshly mixed concrete, ensuring the quality and durability of the urban infrastructure.

• Road and highway construction and maintenance:

  Mixers are crucial in making and mending highways and roads. High-capacity mixers are often chosen to meet the high-volume demand for concrete in road projects.

• Precast concrete production:

  Ajax concrete mixers are commonly used to produce precast concrete products such as concrete pipes, barriers, blocks, tiles, etc. These products are widely used in construction, infrastructure, and drainage projects.

• Production of ready-mix concrete:

  Ajax concrete mixers play a crucial role in the production of ready-mix concrete. Ajax offers a wide range of concrete mixers, from smaller mixing machines to larger stationary and mobile mixers, to meet different production needs.

• Agricultural sector:

  A concrete mixer is commonly used to prepare livestock housing, fencing, and other agricultural infrastructure. It helps improve the efficiency and sustainability of agricultural production.

How to Choose an Ajax Concrete Mixer

Choose the proper Ajax concrete mixer by evaluating several key factors. Match the mixer's specifications, such as volume capacity and dimensions, to the kinds of projects that will use it. Think about the fuel power source for the mixer and its established track record in usage.

The mixing capacity must be high enough to handle the project's demands but not so large as to be economically wasteful. As a guide, 350 liters is sufficient for mixing 0.1 to 0.15 cubic meters, while 140 liters is sufficient for mixing 0.02 to 0.06 cubic meters.

A diesel-powered mixer has greater torque and fuel economy than those powered by electricity. A self-contained diesel mixer has portability advantages, while a stationary electric mixer must have a long enough cable to reach the power source.

The durability of a mixer stems from the steel plate's thickness and the welds used to join the drum's parts. A well-chosen mixer will have an anti-abrasive liner and tiles inside the drum to prevent damage. Other useful parts are the removable, replaceable guides and flaps that further protect the drum from wear.

The drum's loading and discharging methods and the operating functions for tilting and drum rotation all need to be specified. Check that the user manual is readily available so that all operating functions can be explained in detail before purchase.

A mixer that delivers up to 130 HP helps to provide a more efficient fueling system. In an era of rising fuel prices, this model can help to lessen project expenses.

Some stationary models have a discharge capacity of 4 to 5 cubic meters every 60 to 90 minutes. Choose a stationary model to set up at the concrete mixing site if the project involves high volumes. Portable models work well for smaller volumes and portability between sites.
