How to Quickly Troubleshoot Self Loading Mixer

When the self loading concrete mixer machine fails, the concrete in in the mixer will also be affected. If the concrete is solidified due to the failure, that will be a great loss. To avoid this situation, the fault of the self loading concrete mixer should be solved in time. How to trouble shoot the self loading mixer quickly?

1. The working principle of tank rotation

Engine power take-off — drive shaft — oil pump — motor — reducer — tank rotation

2. Analysis of the possible reasons

The main reasons for the stop of the mixing tank are as follows:

l Engine failure: the engine cannot start or the power take-off is damaged.

l The bodywork failure: It may be damaged drive shaft, oil pump failure, dirty or insufficient hydraulic oil, motor failure, reducer failure or loose control lever.

3. Find the fault.

When the self loading mixer has some fault, it should be stopped for inspection. We can judge whether there is any abnormal noise from the transmission shaft to the reducer parts through listening and check whether the hydraulic oil tank oil level is too low or the pipeline has a serious oil leakage. Move the the servo rod of the oil pump forwards and backwards to see if the tank body rotates

4. Emergency measures

If the self loading mixer machine can’t be repaired before the concrete is solidified, emergency measures should be taken immediately:

• Connect the "emergency oil pipe" to unload the concrete when the motor and reducer are free of faults.
• If there is something wrong with the motor and reducer, open the manhole cover. If the manhole cover is not under the tank, you need to open a hole at the bottom of the front cone of the tank.

At the same time, pour a large amount of clean water into the feed port, flush the concrete in the tank until no concrete flows out from the tank. A small amount of residual concrete in the tank needs to be manually cleaned and after the complete cleaning, re-weld the cut part to the tank body.

How to Build An ECO-friendly Hot Asphalt Plant

The environmental pollution such as smoke, dust, noise and high energy consumption generated by the hot asphalt plant during the production process has always been criticized. Asphalt batching plant with with large pollution and high energy consumption has been ordered to shut down in many countries. How to build an ECO-friendly hot mix asphalt plant for sale? There are some measures for dust prevention.

1. Site management

Site management can reduce dust emissions and improve the comfort of the plant. Sprinkle water on the roads and try to reduce the dust caused by the loader and truck in the dry weather. Negative pressure devices are provided in those places including the screening, metering, mixing and hot aggregate bin.

2. The dust removal system of the cold storage

The dust of asphalt hot mix plant is mainly produced by cold material feeding and heating. The cold aggregate feeding belt is equipped with a separate dust removal system. During production, the fan is turned on and the pulse dust collector starts working.

3. Dust removal system of the mixing tower

The mixing tower is equipped with negative pressure devices. The dust removal system adopts atmospheric back blowing dust removal and two-stage dust removal, which effectively prevents the phenomenon of dust overflow.

4. A closed management of the mixing tower

In order to control the problem of disorderly discharge of dust, the mixing tower is completely closed and treated with negative pressure. There is also a temporary overflow storage bin for the centralized treatment when the bin is full, effectively preventing the dust caused by continuous overflow.

5. Closed storage of cold materials
The cold aggregate is stored in a closed plant or silo. The fully enclosed design of the material yard prevents the dust from escaping outwards, and also prevents the aggregates from being exposed to rain to increase the moisture content of the aggregates, thus reducing the additional energy consumption caused by drying the aggregates.

It is certain that for the ECO-friendly hot mix asphalt plant, they are all equipped with advanced bag dust removal system.

As an economic construction equipment, the diesel concrete mixer pump also has its disadvantages:

1. It takes a long time to lay pipes for pumping.

2. As the pouring position changes, the material point must be continuously moved manually.

3. It only can be driven by a tractor, of which the speed is relatively slow.

4. Its mixer is usually JZC/JZM concrete mixer, which the concrete production per hour is not so high.

5. The supporting construction components need to transported together, including generator sets, pumps, pipelines, forklifts, rotating brackets and other tools. So its movement is not flexible enough.

Although the small concrete mixer and pump has these disadvantages, it is still a very popular choice for small projects. Why? Compared with the large concrete boom pump, its biggest advantage is the price advantage.

Because of its small size, good pumping performance, and high cost effective performance, it is very attractive to customers who want to buy the concrete equipment, but the funds are not very abundant.

In addition, the maintenance cost of the concrete mixing pump is also relatively low. Even there is something wrong with the equipment, the cost of replacing parts will not be too high. What’s more, another reason why rural construction customers like it is because of the labor saving.

No machine is perfect and any of them is designed for a special purpose. If you need an economic concrete mixing pump, that will be your choice.

The Production Quality Control of Hot Mix Asphalt Plant

It is necessary to strengthen the installation and maintenance of the hot mix asphalt plant for sale, thus ensuring the safe and efficient operation of the whole plant. It also will ensure the quality of the asphalt mixture and improve its own economic benefits. How to control the production quality?

1. Minerals

In the construction process, the coarse ore material is the gravel of which the size is from 2.36mm to 25mm. During the construction process, the coarse aggregate must be cube particles after being crushed.

2. Asphalt

Before using, all indicators of the asphalt must be checked to ensure its quality. When selecting asphalt grades, be sure to investigate the local climate. When the temperature is low, the ones with high asphalt grades should be selected, mainly because the high-grade asphalt has better crack resistance when paved.

3. Aggregate

Aggregate is the main factor that affects the strength of asphalt concrete. The key part that controls the aggregate grading is the vibrating screen. The mud content of the aggregate will also affect the adhesion performance of the aggregate and asphalt and the stability of the mixture. Therefore, before mixing the mixture, the muddy aggregate should be cleaned.

4. Temperature control

The mixing temperature determines the viscosity of the asphalt. At high temperatures, the asphalt has a high fluidity, so that the aggregate can be completely wrapped. However, if the mixing temperature is too high, the aging of asphalt will be very serious.

Generally, the mixing temperature of the hot asphalt mixture is 130～160℃, and the modified asphalt mixture temperature should be 10～20℃ higher than that of the ordinary asphalt mixture.

5. Mixing ratio

The mix ratio of the asphalt is determined by numerous test in the laboratory. During the production, each material should be feed in a certain order. During the mixing process of hot mix asphalt plant, all aggregate particles should be wrapped by the asphalt. The mixing time should be controlled between 45-90 seconds, and must be checked at any time.

As a big asphalt batching plant manufacturer, Haomei Machinery has made several innovative improvement in aggregate grading and asphalt weighing and spraying, thus ensuring the asphalt mixture in accordance with strict mixing ratio.
