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.

A construction crusher signifies a piece of equipment that is intended to reduce the size of large rocks or gravel, for construction purposes. Crushers can also be utilized to transform the shape of waste matter for simplicity in disposal, or recycling. Crushers are also employed for reducing the raw materials mix size for their differentiation, and segregation. Crushing involves transmission of a force that is significantly increased, by using other materials with a greater bonding strength. These added materials being strong resist deformation, and the required substances are crushed easily. The crushing mechanism holds the material to be crushed between solid surfaces. A force is applied that brings the surfaces close to each other. Energy is generated within the materials to be crushed, and cause the separation of the molecules. The ancient crushers were stones held by hands. The stone weight enhanced the human energy being used.Functioning Of CrushersThe raw materials of different sizes are brought to the hopper by trucks, or other means of transportation. A feeder mechanism regulates the speed of materials entrance at the crusher. A screening machine prevents the smaller parts from reaching the crusher. Main crushing decreases the size of larger pieces for easy management by the crusher. Some crushers can manage rocks, asphalt, and concrete into desired shape and dimensions by breaking, or compressing the materials. Crushers are normally classified by the size limit of the materials that can be processed by the crusher. Crushers reduce the particle size for further processing by grinders. There has not been much significant advancement in the crusher technology, except a few minor improvements. Protection mechanism has been introduced for the prevention of equipment damage, if hard objects enter the crusher. The rotating speed has been increased that has enhanced the speed of crushing.Hydraulic Concrete CrushersConcrete crushers that operate hydraulically are employed for the efficient demolition of concrete. They are also known as concretesmashers and concrete processors. These crushers reduce the concrete size into pieces that can be easily managed or recycled, and also split the concrete from steel reinforcement. Numerous types of jaws are used, including the shear jaws, cracking jaws, and pulverizing jaws. The jaws used are in accordance with the material characteristics, and the size required by crushing. Secondary crushers are also employed to further demolish the rubble created by the primary crushers. The major advantages of hydraulic crushers are silent operations, reduced dust and vibrations, and ease in operation. These crushers can rotate on all sides, with the capability to perform numerous functions with the same demolition tool.

Concrete ranks among the most important recycled raw materials. It can be found virtually everywhere, is particularly high in quality and is very strong. This means that it can be reused in an extremely wide variety of ways.

Here are only some of the many opportunities: aggregate in the concrete industry, road substructures, ready-mixed concrete industry, concrete blocks, paving, prefabricated concrete elements and many more.

Groundwork Solutions Limited have updated their operations with an RM 70GO! 2.0 for crushing construction and demolition concrete. After a successful trial period, they purchased the RUBBLE MASTER impact crusher because of its compactness and great performance.

In Chinas capital city there are strict environmental regulations that not every crusher can easily fulfil. At the same time crushing takes place in the tightest space, which is why the size and manoeuvrability of the machine is decisive. For Mr. Fan it was soon clear that only the RM 90GO! could make

Schouten Excavating is the best example of hard work paying off: The Canadian business began by tackling general excavation, property line clearing and some farm demolition with a single excavator. Today, they own an RM 100GO! and are very successful in demolition and concrete processing.

8,500 tons of material were crushed on site at Salzburg Airport by the compact crusher. The RM 100GO! recycled the concrete from the demolished runway into a value aggregate, which was reused on site to build a new runway. The crusher enabled a sustainable, regional cycle of resources.

In 2010 a severe winter destroyed the beach promenade in Haifa. G. Ream Construction Ltd. was commissioned with the refurbishment and came into contact with RUBBLE MASTER and on-site recycling for the first time. The result was an amphitheatre and a new line of business for Dubi Hyams.

The RM 120GO! effortlessly meets the strict environmental regulations in China. The unique drive system and dust suppression system ensure the lowest emissions and noise. Moreover, thanks to the RM wind sifter, the quality of the final aggregate has been improved even further.

The RM 120GO! effortlessly undercuts the strictest environmental regulations in Basel. The figures are impressive: 90 % of the processed material is used again. That saves 40 % of truck journeys. Its low diesel consumption also impressed the customer.

Alfred Lauzon founded Northern Paving in 1964 and entered the recycling business four years ago. He shares RUBBLE MASTERs strong focus on quality, which was one of the reasons for purchasing the RM 80GO!. He now has companies from all over south west Ontario as customers.

The mobile RM 100GO! impact crusher is currently processing 40,000 m of steel-reinforced concrete. The material will then be reused in the construction of what will be the tallest building in Israel. The impressive throughput performance in combination with the compact design were the main reasons for the RM crusher.

The RM 70GO! handles its first concrete crushing job in Argentina in impressive style. The RM 70GO! was the first crusher for the customer, who was enthusiastic from the outset. Not only the simple handling but also the transportability and usability in the middle of the city centre were convincing arguments.

Harald Zehetner was not actually planning to trade in his existing crusher for a new one until the following year. After a demonstration of the RM 90GO!, however, he was so enthusiastic that Zehetner Transporte Erdbau GmbH were soon the proud owners of a new RM impact crusher.

It needs to be a very special machine if it is not going to overheat in this heat: the RM 70GO! not only manages that easily, it also manages to process large concrete blocks. With the high performance components of the OS70GO! oversize grain separator and the TS3600 high performance screen, waste material

Hurricane Irene left a trail of damage through the United States in August 2011. This called for crushers that are able to process the widest range of materials to clear mineral materials such as riverbed gravel, concrete and asphalt. The advantages of the RM 70GO! and the RM 80 were unbeatable.

The environmentally friendly RM crushers are the ideal partners for a showcase project like this: the worlds first zero-carbon city is currently under construction in Abu Dhabi. 100,000 m of material are processed by the RM 80GO!. The crusher didnt even need to be modified to meet the strict construction site conditions.

Higher performance and better quality in recycling production waste is no illusion. A concrete manufacturer replaced their jaw crusher with an RM 60 in combination with an RM VS60 prescreen and RM CS2500 post screen. In addition to higher quality, they brought the company enormous cost savings.
