The mixer is a very important vehicle, so it must be carefully considered before purchase.
Before purchasing, we need to know many important things, including quality and cost, so we should start with some basic things.
When selecting a mixer truck, you should consider the following issues:
Your purchase purpose, budget, model, and configuration.
Do you want more mixers?
1、 Purpose of purchase
Before purchasing a mixer, you should know what you want, and then select the mixer that best suits your needs.
Mixers are divided into self-dumping, self-suction, dry mixing (wet mixing), semi-dumping, etc. Each type of mixer has its own characteristics.
Will you ask what kind of mixer you want when you buy it? For example, if you buy a concrete or mortar mixer, you need to have enough power to drive the vehicle. In this case, it should match the size of the vehicle, such as a three-axle or four-axle mixer.
For construction machinery, the most important thing is that it must be suitable for working in harsh environments.
For example, diesel and natural gas mixers are used in hot and cold places;
Use electric equipment in cold and wet places;
Operating equipment in cold or wet areas requires special treatment or maintenance.
If you want to buy a mixer truck at the lowest cost, you should consider the following factors:
Your vehicle configuration and type. If you want to buy a mixer, you should choose any type that matches the vehicle configuration.
Do you drive or rent? Are there long-term lease plans, payment methods, and service terms?
How much do you need to pay for the down payment and maintenance?
If you need to transport concrete throughout the country, are there any preferential policies?
I suggest you choose the model with the highest cost performance.
Now the mixer has developed into different configurations, from heavy, medium, and small to mixing tanks.
The mixing cylinder is a tank body, and the mixing tank is a fixed connecting part between the mixing cylinders.
Usually, the concrete in the mixing tank will overflow from the top to the bottom, resulting in an uneven mixing process.
It is also important to select the proper mixing bucket according to the concrete type.
For example, in dry production, concrete is difficult to mix and even, so wet production equipment is required.
When used with other types of mixtures, it is easy to cause serious mixing problems because there is no obvious boundary between them. Therefore, the wet mixing method is more suitable for the dry mixing method equipment.
Of course, there are some special cases for different kinds of products. For example, when special treatment (such as the dry method and wet method), mixed materials (such as cement blocks), or liquid materials (such as cement powder) are required, specific models of products (or special mixer trucks) will be used.
It depends on the engine, transmission, and chassis you choose.
The engine you choose must meet all requirements to ensure sufficient power.
Various accessories can then be added to the chassis to meet various needs.
For example, agitators, mixing drums, screws, reducers, and other accessories need to be installed for agitators.
Different mixers are suitable for different working conditions, but if necessary, you can choose the pump and motor to match these parts.
In this process, you need to purchase a series of accessories to meet the special requirements of the chassis.
Does this include a gear reducer, transmission shaft, bearing, spiral bushing, and other components requiring larger specifications or special functions?
The mixing drum is a key component.
If the mixing drum is too long or too wide, it is not conducive to the use of transportation and maintenance materials, and will also increase costs; If the mixing drum is too short, it will cause uneven mixing or easy blockage.
Therefore, attention must be paid to whether the length meets the standard requirements, whether the width is appropriate and can match the standard mixer: whether the height is lower than the standard mixer; Is the width as specified?
For the transportation of cement mixture, different configurations are required to adapt to various working conditions.
For example, the use of water cooling or air cooling when the temperature exceeds 85 degrees will increase the cost of concrete and lead to increased vehicle failures; When the temperature is lower than 45 ℃, air cooling, air cooling or water cooling cannot improve the working efficiency; Due to the low temperature of the concrete, the concrete shrinks, causing cracks.
5、 Quality and cost
The quality of the mixer depends on its material, quality, assembly process, maintenance technology, and part design.
Many systems are installed on the mixer, including the safety system. If these systems are not reliable, the normal operation of the whole mixing equipment will be affected, and even personal injury will be caused.
In order to reduce costs, some manufacturers cut corners on some small parts, which affects the performance and service life of vehicles.
