Mobile Coal Crusher power system

Crawler Mobile Coal Crusher is a set of receiving, crushing, screening, iron removal and transportation as one of the equipment. It consists of receiving system, feeding system, crushing system, power system, conveying system, traveling system, hydraulic system, etc. Among them, the power system is the “heart” of the crawler Mobile Coal Crusher. There are five main driving modes: direct drive + hydraulic drive, direct drive + electric drive, full hydraulic drive, trunk drive, diesel electric drive, etc. Analyze and compare.

1. Direct drive + hydraulic drive

The diesel engine is used as the power source, and the two output terminals are separated by the transfer case. The main output is connected to the clutch or hydraulic coupling used to drive the crusher; the other output drives the hydraulic pump set to complete the walking, feeding, conveying and folding of auxiliary equipment.

Direct drive + hydraulic drive is the main driving mode at home and abroad, such as XCMG, kliman, Kester and other crawler Mobile Coal Crusher manufacturers, all have this driving mode.

The driving mode is compact and the transmission efficiency is high, but the driving mode does not only need the main line driving, which is the biggest restriction factor to promote the crushing and screening equipment equipped with the driving mode.

2. Direct drive + electric drive

The driving method takes the diesel engine as the power source, and three output ends are separated by the transfer case: the main output terminal is connected to the clutch or hydraulic coupling to drive the crushing main engine; the other output end is connected to the pump set to drive the track and other hydraulic actuators. The third output drives the generator, feeding and conveying are completed by the motor.

There are also many direct and electric drive applications, such as RM, Kleinman and other crawler Mobile Coal Crusher manufacturers.

This driving mode is more convenient than direct driving plus hydraulic driving mode, which is convenient for future maintenance. However, due to the large power of the walking system, the pump unit model is large, which leads to a significant increase in production costs, and the overall layout requirements are high. In addition, due to the use of diesel engine as a power source, the use cost is also high.

3. Full hydraulic drive

The full hydraulic drive uses diesel engine as the power source to supply pressure oil to the hydraulic system through the series pumping unit. The crusher is driven by a separate variable displacement piston pump, and other actuators are controlled by the rest of the pump group and valve group. Full hydraulic drive method is more mature in its crawler Mobile Coal Crusher products.

The driving method has the advantages of low production cost, relatively easy structure arrangement and simple control. The main reason is that the torque of the crusher is large at startup and the rotation speed is high during normal operation. Therefore, this driving method is mainly used in small Mobile Coal Crusher products.

In addition, this driving mode requires high performance of hydraulic components. Many hydraulic components need to be imported from abroad, so the use cost is high.

4. Trunk driver

The crawler Mobile Coal Crusher is driven by mains power. The traveling system is driven by diesel engine, driving the traveling motor to complete the traveling action, and the rest of the actuators are driven by mains power. The biggest advantage of the utility driven mode is low cost. In addition, the structure is large and well maintained.

The crawler Mobile Coal Crusher is basically domestic, such as Nanchang mining machinery. The semi Mobile Coal Crusher also uses this driving mode. The limiting factor of the city electricity driving mode is the small scope of use, and the cables need to be equipped in the mining and construction waste disposal places.

5. Diesel electric driver

The diesel electric mode uses the mains or diesel generator set as the power supply. In the actuator, the motor is driven by electric motor and hydraulic pump, and other actuators are driven by electric motor.

Diesel electric drive mode is similar to plug-in hybrid drive mode of automobile, which is the development direction of tracked Mobile Coal Crusher. This type of crawler Mobile Coal Crusher can be connected to the power supply in large projects to reduce the use cost. In small projects, diesel engine can be used, which is flexible and convenient to use.

At present, many models of crawler Mobile Coal Crushers produced by kleemann in Germany adopt this driving method. The main constraints are high manufacturing cost, complex equipment structure, small structure space and later maintenance difficulties.
