Construction waste sand making machine is suitable for applications in industries such as hydropower, building materials, highways, and urban construction. It can use construction materials, limestone, granite, river pebbles, concrete, and other materials to manufacture highway surface materials and highway pavements Aggregate for gravel and railway

As far as jaw crushers are concerned, although the structure types are different, their working principles are basically similar, except that the moving trajectory of the movable jaw is different. In a nutshell, when the movable jaws periodically reciprocate around the suspension axis to the fixed jaws, sometimes approach and sometimes leave, ore between the two jaws when the movable jaws approach the fixed jaws It is broken by the combined action of crushing, splitting and bending and breaking; when the movable jaw plate leaves the fixed jaw plate, the crushed ore is discharged through the ore outlet of the crusher under the action of gravity

1. Frame design-integral casting vs split assembly Due to the limitations of casting technology, the overall casting frame will form a large number of tiny pores or inclusions during the casting process, so the overall performance of the frame is reduced. Relatively speaking, the split-assembly rack-type jaw crusher is lighter, stronger and more durable

2. Jaw plate design-overall vs three-stage Large jaw crushers mostly use three-stage combined jaw plates. In addition to being more convenient for assembly, installation and disassembly, the main thing is the small one in the middle, the size of the two ends is the same. If the bottom end of the jaw plate is worn seriously, you can The position of the upper jaw is reversed and continued to be used, saving costs

3. Fixing method of bearing seat-welding vs bolt Some jaws are broken, and the bearing seat is welded to the frame, and some bearing seats are made of integral cast steel structure and are connected to the frame with bolts to ensure complete cooperation with the crushing frame and greatly enhance the radial direction of the bearing seat. strength. Different manufacturing processes make the service life of the two different. In addition, some jaws are broken and heavy protective plates are installed on their bearing seats to avoid accidental damage to the bearing seats

The vertical shaft impact crusher is a commonly used sand production equipment in the sand production line. It is very important for the sand making process. The vertical shaft impact crusher has high production efficiency, but after a period of use, pay attention to the wear of the equipment. Vertical shaft impact crusher has long-term contact with sand and gravel…

The process of crushing machine-made sand includes dry sand making and wet sand making. Both methods can produce high-quality sand and gravel. The wet sand making machine can clean the sand and gravel very cleanly, and it can also recycle the sand. Dry sand making equipment is relatively simple and does not need to consume a lot of water for…

In recent years, construction waste has become a hot commodity. The main reason is the use of mobile crushing stations. Mobile crushing stations are an indispensable tool in the process of urban construction and can effectively help cities become greener and more environmentally friendly. How does the mobile crushing station make construction waste a popular item? From the comprehensive utilization…

The South Ring Road project is a key urban construction project that Luoyang City is accelerating. At the same time, the project also has a feature, the amount of demolition along the route is very large, and a large amount of construction waste transportation will bring about waste of resources and dust pollution. "After research and experiments, we decided to…

the plastic waste bricks being used in construction

The plastic crisis is one of the greatest global environmental threats currently facing mankind. As landfills and oceans alike fill with plastic waste and microplastics work their way into the food chain, Nzambi Matee has developed a strategy to potentially solve the problem of plastic pollution

As Matee describes her product’s viability as a building material, she provides a striking demonstration of her claim, hefting brick above her head and then casting it against a school footpath made from bricks containing recycled plastic. The brick strikes the footpath with a powerful thud but leaves no trace of damage to the bricks that comprise it. 

Matee uses different kinds of plastics in her factory, producing one and a half thousand bricks a day. The factory processes both high and low-density polyethylene, the former mainly used in plastic bottles, the latter common in wrapping film and bags made to contain foodstuffs like cereal.

Plastics are strong, waterproof, lightweight, easy to mould, and recyclable, all of which are properties that we actively look for in building materials. And whilst their incredible durability is a major problem when they find themselves flooding into the environment, it's a boon for the building trade. 

Many learning institutes are hot on the trial of effective ways of turning waste plastics into building materials, and this extends beyond bricks and tiles. Promising applications include the creation of concrete¹ and lightweight plasters and mortars². 

One recent breakthrough was pioneered by Australian researchers who developed a ‘green brick’ that mixes plastics with waste plant fiber and a new type of rubber polymer³ — made from sulfur and canola oil

Matee takes a slightly different approach to this, actually mixing waste plastics with sand. This mixture is then heated and compressed into the bricks that Matee sells for around 8 USD per square meter. 

Part of Matee’s drive to do something with plastic waste was born from the frustration of watching the government do little to tackle the problem of plastics pollution, and it is vital to remember that even large movements have small beginnings
