Application field crushing and screening of asphalt milling material and concrete waste material.
Equipment highlights high production efficiency, green, environmental protection.
Asphalt concrete pavement will inevitably have problems such as aging and cracking after a period of use. To repair, renovate or refurbish asphalt concrete pavement, the most commonly used treatment process is to use a milling machine to mill the asphalt concrete pavement to the upper layer, and then spread new asphalt concrete to repair or improve the original road surface.
Today, advocating 8220green environmental protection8221 and 8220protection of primary resources8221 will be of great significance for the use of milled asphalt concrete waste. After crushing and sieving the waste asphalt milling material, adding regenerated asphalt reducing agent, a small amount of new aggregates and asphalt mixture for pavement paving. This not only avoids the environmental pollution problems caused by the stacking and landfilling of waste asphalt milled materials, but also greatly reduces the use of asphalt and natural aggregates.
The customer purchased a set of crawler mobile crushing and screening production line for crushing and screening of asphalt milled material. The crushing and screening production line is mainly composed of a crawler moving impact crusher and a crawler moving inclined aggregate screening machine.
The waste asphalt reclaimed material is loaded through the loader to the counterattack. After the material is pre-screened by the counterattack breaking grate, the fine material is pre-screened, and the large material enters the counterattack crusher and is crushed. Below the main conveying belt of the impact crusher is equipped with a return material screening system, the oversized materials can be directly returned to the impact crusher and then crushed.
Crawler mobile inclined three-layer screening equipment has high screening efficiency and convenient operation. The four-stage conveyor belt can be adjusted in position through an innovative hydraulic control system during stacking and feeding. The materials that meet the size requirements enter the sieving machine for classification processing, and finally produce 4 standard specifications of finished materials.
The production line can produce 4 kinds of standard specifications of finished materials, which are 0-7mm, 7-15mm, 15-20mm, 20-40mm, and the hourly production capacity is 120-150 tons.
Discharge port setting first counterattack plate 80mm second counterattack plate 40mm Material return screen setting 40mm Engine speed 2000rpm Engine load 30 Average fuel consumption per hour 22L h Service life of main wearing parts about 300h board hammer.
Summary In the process of disposal, portable crusher plant plays an important role because of its convenience, high efficiency and large capacity.
China39s construction waste output will reach a peak in the next few years due to large-scale old city renovation and accelerated urbanization. Construction waste disposal and recycling is a way to solve the urban construction waste siege with both economic and social benefits. In the process of disposal, portable crusher plant plays an important role because of its convenience, high efficiency and large capacity.
Portable crushing plant is a series of crushing equipment for rock and construction waste, which is widely used in mining ore crushing, construction waste recycling, construction aggregate production, expressway, railway, road and bridge construction and other industries. It truly provides customers with efficient and low-cost hardware facilities for project operation.
Portable crusher integrates vibrating feeder, crusher, screening system, sundry sorting device and transmission mechanism, etc. It is equal to a mobile plant. The structure of it is as following.
The main function of vibrating feeder is to evenly feed and improve the working condition of crusher.Generally choose bar feeder, in the material is subjected to vibration, sliding forward into the crusher, those small particles of construction waste, will fall from the gap between the bar, play the role of screening.
Crusher is the core part of portable crushing plant, mainly responsible for crushing construction waste. As construction waste belongs to medium hardness materials, no viscosity.As for water content, itdoesnrsquot have too high requirements, so generally meet the requirements of stone crushing equipment can be applied to the portable crusher plant of construction waste recycling.
In order to ensure the quality of recycled aggregate after crushing, secondary crushing is needed for those whose particle size cannot meet the requirements after primary crushing. It requires adding a screening system to screen the concrete blocks with larger particles and sending them back to the crusher for re-crushing, so as to ensure the crushing quality of construction waste.
The portable walking mechanism has a high chassis and a small turning radius, which is convenient for driving on ordinary roads. Vehicle-mounted generator sets can provide a continuous source of power for the equipment.
The content of sundries in construction wastes is more, such as waste iron, wood, glass and waste plastic, especially in reinforced concrete, waste steel, waste iron wire is more, so it is necessary to install a sundries sorting device in portable crushing plant, to eliminate the impact of waste steel, waste iron wire on the performance of recycled concrete aggregate.
Last, a mention for you If your budget is limited, the best choice for you is portable crushing plant not mobile crushing plant. Because the portable crushing plant price is lower than another.
