Concrete block often appears after building and bridge demolition, which will cause problems like pollutions and land waste. There are mainly 5 types of concrete crushers like portable concrete crusher, mobile concrete crusher, small concrete crusher, excavator concrete crusher and bucket crusher, so you have to choose the right crushing machine according to your own situation.
A portable stone crusher, a wheeled-mounted crushing machine, is a perfect machine for processing concrete waste because of its strong flexibility. Concrete recycling manufacturers always know that if they choose to set up a fixed crushing line, they have to pay more time, money for labor and transportation.
A portable crusher can load various fixed crusher machines like fixed jaw crusher, impact rock crusher, hydraulic cone crusher, etc. Therefore, it is a mobile crushing plant integrating crushing equipment, conveyor, and power control equipment. It can last for 20,000 hours under difficult conditions while 30,000 hours under normal conditions, and then needs to be overhauled so that its service life can be extended.
This Indian customer purchased FTM938HD80 portable jaw crusher, portable impact crusher, and portable stone screener. These machines can not only produce a wonderful cubical shape of products but greatly reduce labor and transportation cost. The original plan was to require three people to spend about half a month fully installing a fixed crushing production line. In addition to transportation costs, the total cost was really expensive.
It can be seen from the table that Fote portable concrete crusher helps customers save costs, improves production efficiency, and brings objective profits to customers. If you are interested in this equipment, you can consult and quote to obtain detailed information about the equipment.
Compared with the tire-type concrete crusher, the unique feature of the mobile crusher is that it uses a crawler or tracked mounting way, which makes it 100 percent free movement and to be operated by remote control.
This British customer ordered a mobile jaw breaker and mobile impact in December last year, but due to the covid-19, he couldn't come to the factory to buy it in person. The sales team of FTM Manufacturer introduced him to detailed equipment information online and provided him with the best solution based on its output, size and other requirements. After talking, he was very satisfied and then purchased machines online in March 2020.
Small concrete crushers are mainly used for crushing with small output, and most of them are jaw crushers with fixed and mobile types. The feed size of the small concrete crusher is not very large, so it can only process smaller concrete materials.
Excavator concrete crusher can make it easy to process concrete mixed with mud and scrap. It is made of high-strength wear-resistant steel, which can be directly installed or hooked to the excavator, which greatly improves the versatility of the excavator.
It is mostly used for the removal of concrete slabs, walls and bridge decks. The jaws of this crusher can be operated without any hydraulic pressure. The crushing process depends on the pressing forces created by movable front jaw and fixed rear jaw, which can separate the concrete from the steel bar and crush the concrete at the same time.
It is also an ideal attachment for recycling different materials. You can just mount the crusher on a wheel loader to demonstrate the outstanding performance of this attachment on reinforced concrete. Usually, one of the most difficult materials to recycle is wood scraps mixed with metal parts.

The rapid development of urbanization has resulted in the accumulation of a large amount of waste concrete, which not only occupies land resources but also pollutes the air and the environment. Therefore, the recycling of waste concrete has become an important issue that the government needs to solve.
Abandoned concrete blocks are high-quality concrete aggregates which have many advantages. For example, after the buildings are dismantled, the high-quality concrete blocks and silt after crushing and screening can be used as recycled coarse and fine aggregates for concrete. The fine powder can be directly used as the raw material of cement. The concrete prepared from recycled cement and recycled aggregate can enter the next cycle, which realizes zero waste discharge throughout the whole cycle.
Concrete, cement and other wastes in construction waste can be used as building aggregates and recycled brick raw materials after being reasonably crushed, screened and crushed. And the main equipment used for crushing concrete can be divided into two types: traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users.
Although the compressive strength and hardness of concrete are not high, due to the porosity and the formation type, the concrete has good toughness and can buffer the crushing force, which causes low crushing efficiency. So, what kind of crusher should be selected for concrete crushing? In the process of crushing waste concrete, according to the working principle of more crushing and less grinding, it is necessary to carefully configure the concrete crusher equipment.
Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.
In recent years, the small jaw crusher has been favored by foreign users because of its small size, easy transportation and installation, low price, and fast profit. The models like PE-150250, PE-200350 and PE-400600 have become the best choice for customers to crush concrete.
After the rough breaking, steel and iron equipment are added to remove the steel bars and iron blocks in the waste concrete, which will eliminate the damage of steel bars and iron blocks to the equipment without affecting the production. Generally, the impact crusher, the fine crushing jaw crusher or the cone crusher is used as the secondary crushing to crush the material to less than 2 cm, and the selected granularity can be basically achieved.
For smaller discharge sizes, a three-stage crusher can be used, for example, the fine crushing crusher or the roller crusher is used to further crush the ore to less than 10 mm. In the actual production, the suitable crusher can be selected according to the size of the concrete block. It can be combined in single or multi-machine operations, both of which have the characteristics of simple operation, strong controllability and high production efficiency.
In the international environment of the crusher industry, besides the traditional jaw crusher, high-efficiency and environmentally-friendly construction concrete crusher will be the trend of future development.
In view of the characteristics of concrete waste, Henan HXJQ Machinery designed a concrete crushing equipment-mobile concrete crusher. The waste concrete after crushing can be used for reinforcing the foundation, producing bricks, cement, etc, not only achieving its values but also solving the issue of land and environment problems, which can be described as two-fold.
The mobile concrete processing station produced by HXJQ Machinery adopts multi-stage combination mode, which includes jaw crusher, impact crusher, cone crusher and vibrating screening equipment, conveyor belt, etc. Generally, the concrete crushing station is composed of a concrete crusher (sand making machine), a screening machine, a feeder, a conveyor belt, a steel frame, a drive system, an electric control system, a motor unit and the like.
The concrete material is sent into the crusher by the feeding equipment, and the crushing machine converts the large concrete into gravel. The finished product which meets the standard is transported by the conveyor belt to the stacking place, and the products which don't meet the standard will be transported by the other conveying belt to the crusher again until it is qualified.
The integrated vibrating screen, feeder and the under-belt conveyor, the vibrating screen and the crusher integrated into the vehicle can reach any position on the working site under any terrain conditions. Thus the mobile concrete crusher has many advantages like reasonable material matching, smooth flow, reliable operation, convenient operation, high efficiency and energy saving.
1. According to the driving way, it is divided into tire type and crawler type: the tire type concrete crushing and sorting machine needs semi-trailer traction to run, while the crawler type can be remotely operated with buttons. Relatively speaking, the latter is more intelligent and the price is more expensive.
2. According to the function, it is divided into crushing type and sand making type: the concrete crushing and screening machine includes a combination of crushing equipment such as jaw crusher, cone crusher and impact crusher. The sand making type is mainly equipped with sand making machine and hammer sanding machine.
The mobile crushing station can prevent and control environmental pollution, improve the ecological environment, and protect natural resources. The size and model can be designed according to the different production needs of users. According to the statistics of the HXJQ machinery, the small mobile crusher is chosen by more foreign users because of its reasonable price, high quality, convenient transition, operation and maintenance.
A project introduction of construction concrete treatment: in October 2018, a customer found HXJQ, and hoped that we could provide him with the complete equipment for breaking construction waste. Our technical manager quickly contacted him and learned that the customer had a large amount of construction waste to be disposed of.
From the perspective of economic foundation and practical operation, the technical manager recommended the fixed crushing station to him and designed a complete set of equipment suitable for his actual needs. In the end, the customer introduced the PE-400600 jaw crusher and PF-1010 impact crusher produced by our company to break the concrete waste. The finished sandstone is used for brick making, roadbed materials, etc., and the separated steel is recycled.
The pretreated concrete with reinforcing steel is sent to the jaw crusher for initial breakage by the conveyor belt, then effectively separated by the iron remover, and sent to the impact crusher for fine crushing. The crushed material is sieved by the vibrating screen. The finished material is output by the conveyor. If the material does not meet the specifications, it will continue to return to the impact crusher and break again.
The development and utilization of waste concrete as a recycled material solves the problems of a large amount of waste concrete treatment and the resulting deterioration of the ecological environment; on the other hand, it can reduce the consumption of natural aggregates in the construction industry, thereby reducing exploitation of the natural sand and gravel, which has fundamentally solved the problem of the depletion of natural aggregates and the destruction of the ecological environment because of the lack of sandstones.
Under this circumstance, the crusher plays an irreplaceable role in the recycling of materials. Whether it is the traditional fixed crusher or the latest mobile crusher, both of them have their own advantages. As long as the size of the stone produced by the equipment can meet the standard, it is a good crusher.
Stone crusher plant can crush limestone, granite, basalt and so on to product aggregates for ready mix concrete, building material, construction site and others. Various final product sizes are available with customizing crushing plant system solution.
