Construction Waste Crushing Station

Common composition of construction waste crushing station

Introduction: Recently, the demand for construction waste crushing stations is increasing. Construction waste equipment, construction waste crushers, and construction waste treatment plants are also increasing, including construction gypsum powder production lines. So what is the common composition of a construction waste crushing station?

Construction Waste Crushing Station

The construction waste mobile crushing station is a moving production line that integrates the vibrating feeder, crusher, screening system, sundries sorting device and conveying mechanism, and is equipped with a walking mechanism.

The first is the vibrating feeder. The crushing is continuous, and the feeding of construction waste is intermittent. If the crusher is directly fed, it will impact the working device of the crusher, causing the structural force to be discontinuous, which may cause impact damage to the equipment. So you need to add a vibrating feeder in front of the crusher. The main function of the vibrating feeder is to uniformly feed and improve the working conditions of the construction waste crushing station. Generally, the rod feeder is used. Before the material is vibrated and slides forward into the crusher, the construction waste with smaller particles will slide off the gap between the rods and play the role of screening.

The crusher is the core component of the construction waste mobile crushing station, and is mainly responsible for the task of crushing construction waste. Since construction waste is a medium-hardness material and has no viscosity, it does not have too high a requirement for water content. Therefore, equipment that generally meets the requirements for stone crushing can be applied to a mobile crushing station for construction waste recycling. In order to ensure the performance of the recycled aggregate, it is necessary to ensure that the broken material is granular, reduce the content of the sheet material, and the particle size distribution should be uniform. Therefore, the crusher has crushing capacity, crushing efficiency, and quality of the material after crushing.

Followed by the screening system of the construction waste crushing station. In order to ensure the quality of the regenerated aggregate after crushing, it is necessary to carry out secondary crushing after the primary crushing particle size cannot meet the requirements. This requires adding a screening system, screening the larger concrete blocks and transporting them back to the crusher for further Broken to ensure the quality of construction waste. At present, the commonly used vibrating screening equipments are linear vibrating screens and circular vibrating screens. Combined with the particle size and grading requirements of the crushed particles of construction waste, it is recommended to use a circular vibrating screen. The upper end of the elliptical long axis of the feeding end of the circular vibrating screen is oriented toward the discharge direction, which is favorable for the material to be quickly dispersed, and the upper end of the elliptical long axis of the discharge end is opposite to the discharge direction, thereby reducing the moving speed of the material and facilitating the screening of the difficult-to-screen material. The arc-shaped screen surface increases the effective area of ??the screen machine, thereby increasing its processing capacity. Moreover, the circular vibrating screen adopts a small amplitude, high frequency, large dip angle structure, high screening efficiency, strong processing capability, long life, low power consumption and low noise.

Then there is the walking mechanism of the construction waste crushing station. There are two types of moving mechanisms for mobile crushers: one is crawler type and the other is tire type. The tire-type mobile crushing station has a high chassis and a small turning radius, which is convenient for driving on ordinary roads, and can be quickly moved to the construction site, saving time and high flexibility of equipment. Vehicle-mounted generator sets provide a constant source of power for the equipment. The crawler type mobile crushing station has a low center of gravity, stable walking, low grounding ratio, good passability, and good adaptability to mountains and wetlands. Generally adopting a full hydraulic drive system, the large torque travel motor of the crawler type travel mechanism has large driving force and high reliability.

In addition, it is a debris sorting device for the construction waste crushing station. There is a large amount of debris in construction waste, such as scrap iron, wood, glass and waste plastics, especially scrap steel and scrap iron wire in reinforced concrete. Therefore, it is necessary to arrange a debris sorting on the mobile crushing station. The device eliminates the influence of scrap steel and scrap wire on the performance of recycled concrete aggregate.

The debris sorting device of the construction waste crushing station may be a iron remover. The iron remover is recommended to use the suspended self-unloading iron remover. It is not recommended to use the manual iron remover for cost saving. The reasons are as follows: 1) The amount of iron in the construction waste is relatively large, and the manual type iron remover needs to be powered off for manual treatment. It takes manpower and time; 2) The dust content of construction waste is high, which will affect the magnetic field strength and iron removal capacity of the iron remover, while the suspended dump iron remover has large magnetic permeability, strong suction, dustproof and rainproof, Corrosion-resistant features for reliable operation in extremely harsh environments.

The debris sorting device of the construction waste crushing station may also be a wind sorting machine. The construction waste is also mixed with light materials such as bamboo wood, plastics, and woven fabrics. These light components can be separated by sorting equipment to improve the purity of recycled materials and the reuse rate of construction waste. Commonly used are horizontal wind sorters and vertical wind sorters. It is recommended to use a fan with simple structure and low cost as a simple sorting device when the capital is limited and the processing scale is small. However, when there is a large amount of soil in the construction waste, the single-use wind opportunity affects the environment of the work area. It is recommended to use a horizontal wind sorter or a horizontal air flow sorter according to the requirements of the recycled materials.

The above is a common composition of the construction waste crushing station, including the vibration feeder, crusher, screening system, walking mechanism and debris sorting device. Specific equipment for each item, users can choose according to their own production needs and economic conditions.
