UM Underground concrete mixer

UM Underground concrete mixer

The underground mining mixer is a low-profile special mixer mainly used in mining and tunnel construction. Due to the small space, humid environment and complex terrain of the construction site, the requirements for mixer trucks are very high. In order to meet customers' requirements for ready-mixed concrete in the aforementioned environment, TRISUN has developed, designed and manufactured compact, powerful, maneuverable and flexible tunnel and mining concrete mixers, providing a good solution for tunnel concrete construction. In addition, TRISUN customizes and manufactures one-way or two-way driving mixers that meet the traffic requirements according to the specific dimensions of the customer's tunnel.

1. Improving construction efficiency. Tunnel construction requires a large amount of concrete. If the traditional manual concrete mixing method is used, manual mixing and transportation are required, which will be very inefficient. However, the UM low-profile mixers overcome the above difficulties and can automatically mix and transport, greatly improving construction efficiency and reducing manpower investment.

Ensuring concrete quality. The special concrete mixer for tunnels can adjust and monitor the concrete while mixing to ensure that the quality of the concrete meets standards and requirements. At the same time, the mixing cycle and speed of the underground concrete mixer can also be adjusted according to different concrete formulas to ensure the uniformity and strength of the concrete.

2. Reducing environmental pollution. The special underground concrete mixer for tunnels can be used for mixing and transportation at the construction site, avoiding dust and noise pollution generated during concrete transportation. At the same time, it’s equipped with an exhaust gas purifier, which maintains the air quality of the tunnel and reduces environmental pollution.

3. Flexible and wide application. UM underground concrete mixers are not only suitable for underground mines, but also for other narrow culverts, tunnels, and bridge construction. It is not only suitable for ordinary concrete production, but also can produce concrete of different qualities and uses according to needs, thereby adapting to different tunnel construction needs.

FAQ

Q: What is the difference between UM mixers and traditional mixer trucks?

A: The main difference between UM concrete mixers and traditional concrete mixer trucks is adaptability and economy. Traditional concrete mixer trucks are mainly used in construction, road construction, water conservancy projects and other fields, so their capacity is generally large. However, UM concrete mixers are mainly used in the construction of mines, tunnels, culverts, railways, bridges, etc., so their capacity is small. Traditional concrete mixer truck chassis are usually provided by well-known truck manufacturers, while UM concrete mixers use our company's patented technology chassis, which is a off-road chassis.

Q: Why is the UM concrete mixer called the "Neither Fish Nor Fowl"? What are its characteristics?

A: Underground concrete mixer, also known as mixer "Neither Fish Nor Fowl", has the characteristics of economical and practical, reliable quality, strong load-bearing capacity, good climbing performance and high durability coefficient.

Its body and front are integrated, making it flexible and not as clumsy as a tractor. It can be equipped with diesel engines of various horsepower according to customer needs. The driving mode is flexible and changeable. The speed of the engine, gearbox and rear axle is low, the torque is high, and the traction is strong. It can effectively improve the climbing degree and performance and is loved by users.

The chassis of the underground concrete mixer is made of the same material as the heavy truck. It is more tough and load-bearing than the traditional frame. It has the characteristics of no deformation or cracking under heavy pressure, and is suitable for use in bumpy and uneven road conditions in mines. It has a wide range of uses and is mainly used in forestry, agriculture, animal husbandry and engineering.

Q: Why is the underground concrete mixer more cost-effective?

A: For short-term projects, it is more suitable to use the underground concrete mixer, especially some tunnel projects and road conditions and construction sites with limited height and width. This mixer can be equipped with various components according to the customer's needs, and unnecessary components will be omitted directly.

For example, if the gradient force needs to be strengthened, the engine horsepower can be increased, and the drum capacity can also be customized according to needs. It adds a lot of practicality and increases the carrying capacity. In particular, small-capacity mixers are widely used in tunnel projects, and they are highly adaptable. 

In addition, since the mixing drum of the underground concrete mixer is capable of rotating and mixing at an adjustable speed, the concrete transported by the mixer can ensure that no segregation occurs within the specified distance and time, the coarse aggregate does not settle, and good workability is maintained.

Q: How should the concrete mixer for underground mining be maintained?

A: The underground mining concrete mixer is an important equipment in the mining production process. In order to ensure its stable operation and extend its service life, it needs to be maintained. The following are the maintenance methods for underground mining concrete mixer:

1) Clean the body and chassis regularly: Due to the harsh mining environment, the body and chassis of a wet-brake underground mining mixer tend to accumulate dust, sediment and other materials after long-term operation, which affects heat dissipation and accelerates wear and tear, and should be cleaned regularly.

2) Regularly inspect the components of the transmission system and suspension system: The transmission and suspension systems are key components of underground concrete mixers and should be inspected and maintained regularly, including checking chains, sprockets, transmission rods, bearings, shock absorbers, etc., to ensure that they are well connected and operate smoothly.

3) Check the brake system regularly: The brake system is a key safety component of the underground mining concrete mixer. It is necessary to regularly check the wear degree of the brakes and whether the brake oil has expired to ensure the effective operation of the brake system.

4) Regularly replace engine oil and filter elements: The engine of the mining concrete mixer needs to change the oil regularly, usually every 3-6 months. At the same time, replacing the oil filter element can effectively protect the engine and extend its service life.

5) Regularly check electrical systems and wiring: The tunnel concrete mixer adopts an electronic control system. The connection and corrosion of the wiring and electrical components should be regularly checked, dirt should be cleaned, and broken wires should be repaired.

6) Regular lubrication: Ensuring the lubrication of key components such as bearings and sprockets of tunnel concrete mixers is the key to its long-term stable operation. Grease and lubricating oil should be added to key parts regularly to ensure the normal operation of components.
