1. Classification according to production process
SBS bitumen emulsification equipment is classified according to the production process and can be divided into three types: intermittent working type, semi-continuous working type, and continuous working type. During production, demulsifier, acid, water, and latex modified materials are mixed in a soap mixing tank, and then mixed with bitumen underwater concrete into a colloid mill. After a can of soap is used up, the soap is redispensed, and then the next can is produced. When used in the production of modified emulsion bitumen, depending on the modification process, the latex pipeline can be connected before or after the colloid mill, or there is no dedicated latex pipeline. , just manually mix the required amount of latex into the soap tank.

Abstract: Bitumen decanter plant plays an important role in highway construction, but traditional heating methods have problems such as high energy consumption and low efficiency. This article introduces a new type of asphalt melting equipment, which uses electric heating technology and has the advantages of energy saving, environmental protection and environmental protection. The working principle of this bitumen decanter is to heat the asphalt through the heat generated by the resistance wire, and then automatically adjust the temperature and flow rate through the control system to achieve the best melting effect.

With the continuous development of science and technology, asphalt melting equipment is also constantly innovating and improving. Future asphalt melting equipment will be more intelligent, professional and environmentally friendly.

In actual work, if we can improve the production efficiency of road construction machinery as much as possible while ensuring the quality of the project, it will undoubtedly bring us more benefits. So, for actual workers, are there any methods to achieve this requirement? Next, we will share with you some information on this issue, hoping it will be helpful.

Usually we refer to the machinery and equipment related to road construction as road construction machinery. In other words, road construction machinery is a relatively broad concept that includes many equipment. So, let’s talk about the maintenance and management of road construction machinery.

Preparations before starting up

1. Check
① Understand the impact of weather conditions (such as wind, rain, snow and temperature changes) on the production day;
② Check the liquid levels of diesel tanks, heavy oil tanks, and asphalt tanks every morning. When the tanks contain 1/4 of the oil, they should be replenished in time;
③ Check whether the temperature of the asphalt reaches the production temperature. If it does not reach the production temperature, continue to heat it before starting the machine;
④ Check the aggregate preparation situation according to the ratio of cold aggregate, and the insufficient parts must be prepared for reproduction;
⑤ Check whether the on-duty personnel and auxiliary equipment are complete, such as whether the loader is in place, whether the vehicles are in place, and whether the operators at each position are in place;
