Common Faults and Solutions for Mobile Concrete Mixer Trucks

2024-10-22

By rotating the tank, the mobile drum mixer truck keeps the sand, stone, cement and other materials in concrete evenly mixed to prevent caking and stratification. In the long-term transportation process, if the concrete mixer does not rotate, the stones in the concrete will sink to the bottom, the middle layer is sand, and the upper layer is cement slurry, which will lead to concrete agglomeration and stratification and affect the quality of concrete. By rotating the tank, the mixture of sand, stone and cement in concrete can be more uniform, thus preventing caking and delamination. Working principle of concrete mixer truck The engine power is transmitted to the hydraulic oil pump through the PTO on the chassis of the mixer truck to produce high-pressure hydraulic oil. High-pressure hydraulic oil drives the oil motor to rotate at high speed, which generates great torque through the planetary gear reducer to drive the mixing drum to rotate. During transportation, the mixer truck keeps rotating at a low speed of 1-3 revolutions per minute to ensure the homogeneity of concrete and prevent the...

Composition and Function of Belt Conveyor in Concrete Mixing Plant

2024-10-22

In the production process of concrete mixing station, the belt conveyor plays a key role in material transportation, with high efficiency and high speed. However, once a fault occurs, all the production of the mixing station will be interrupted. Therefore, as a manufacturer of concrete mixing station technology, only by knowing the composition structure and installation steps of the belt conveyor can we do a good job in handling common faults and daily maintenance. What is a belt conveyor Belt conveyor is a machine driven by friction, which transports materials in a continuous way. The machine consists of a driving device, a tensioner, a conveyor belt intermediate frame and idlers. It uses the conveyor belt as a traction and bearing part, so as to continuously transport loose materials or finished products, and then continuously transport materials/objects from the initial feeding point to the final unloading point. This machine can not only transport broken materials, but also transport finished articles. Classification of belt conveyors According to bandwidth: 650mm, 800mm, 1000mm, 1200mm, etc. According to the belt style and shape: flat belt,...

How Much Do You Know About Concrete?

2024-10-14

Concrete is a common building material in civil engineering and is widely used in all kinds of civil engineering. It is mainly used in the structural parts of buildings, such as foundations, walls, beams and columns. Concrete has high strength, durability and good plasticity, which makes it an ideal material for building high-rise buildings, bridges, roads and other infrastructure. Mass concrete refers to mass concrete with the minimum geometric size of not less than 1 meter, which is often used in high-rise building foundation, large equipment foundation, water conservancy dam and other projects. Because of its large volume, concentrated release of hydration heat of cement and rapid internal temperature rise, it is easy to cause temperature cracks, so it is necessary to pay special attention to the hydration heat and the volume deformation caused by it. Permeable concrete is a kind of building material with good permeability, which is widely used in roads, sidewalks, squares, parking lots and other places. It can effectively drain water, prevent water accumulation and flooding, reduce the consumption of groundwater resources and improve the utilization...

What Should be Paid Attention to in Concrete Construction in Spring?

2024-09-29

Because it is dry and windy in spring, the temperature difference between day and night is large, the temperature of concrete varies greatly in different time periods, and the temperature difference between inside and outside of concrete is also large, which is easy to form temperature shrinkage cracks. In this season, the air is dry, and the wind is stronger on the empty construction site floor, and the surface of freshly poured concrete loses water quickly, which is easy to form air-dried plastic shrinkage cracks. In order to ensure the construction quality, the following points should be paid attention to in spring concrete construction: I. Preparation before construction There will be some noise during the operation of concrete mixing station, which will have a certain impact on the surrounding environment and residents' lives. Therefore, concrete mixing stations should take effective measures to reduce the generation and spread of noise. (1) Check whether the construction equipment is in good condition, such as mixing station and delivery pump. (2) Check the formwork, steel bars, etc. to ensure that their sizes and positions...
