Jun 11 2020 Smart crusher has developed a technique for recovering the sand gravel and the cement from concrete. This unique technique has been tested and proven on a laboratory scale and in practice. Traditional concrete crushers are huge. A traditional concrete crusher breaks right through the sand and gravel. Smart crusher on the other hand crushes only the cement stone leaving the
Following is the procedure of manufacture of cement by the dry process using modern technology a Most of the cement factories are located very close to the limestone quarries. The boulders upto 1.2 m size are transported in huge dumpers upto 300 kN capacity and dumped into the hopper of the crusher.
Feb 20 2020 The technology of separating the hardened cement mortar from the coarse aggregate and partially crushing this mortar is characterized by the fact that the process is carried out in one device . The operation of the device involves continuous feeding a higher section of the pipe mill with shredded concrete rubble 4.
Oct 23 2015 Cement is an energy-intensive industry in which the grinding circuits use more than 60 of the total electrical energy consumed and account for most of the manufacturing cost .The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent years the production of composite cements has been
Concrete Technology Ch.1 Dr. Basil Salah Comparison between wet and dry process Wet process Dry process 1- Moisture content of the slurry is 35-50 1- Moisture content of the pellets is 12 2- Size of the kiln needed to manufacture the cement is bigger

The cement production process for example starts with mining of limestone which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker.
Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing and involves maintenance of desired moisture and temperature conditions both at depth and near the surface for extended periods of time.
Concrete to high-quality concrete. In this project an installation is being built in the border region to process concrete debris into the original cement sand and gravel components SmartCrusher technology. The hydrated cement is regenerated in a microwave oven. This way new high quality concrete can be made from concrete rubble.
For example 1kg Portland cement 1kg CO 2 pollution. Smart Crusher BV. is frontrunner in developing a patented technology to liberate all the concrete ingredients. The cementstone as a CO 2 free cement kiln feed or as real cement cement in old concrete is never fully hydrated and so directly reusable.
