before the computer-based universal material zeroing of China Construction machinery information, there was no work to make the task platform rise for a period of time, and the machine was connected to power

Guide: from August 23 to 25, 2013, the ready mixed concrete branch of China concrete and cement products association The technical exchange meeting on the production of machine-made sand and artificial aggregate and its application in concrete hosted by the sand and gravel Work Department of Beijing Concrete Association was grandly held in Beijing. As a co organizer, Nanfang Road Machinery Co., Ltd. carried V7 dry sand making equipment

from August 23 to 25, 2013, a technical exchange meeting on the production and application of machine-made sand and gravel artificial aggregate in concrete hosted by the ready mixed concrete branch of China concrete and cement products association and the sand and gravel Department of Beijing Concrete Association was held in Beijing. As a co organizer, Nanfang Road Machinery Co., Ltd. took part in the meeting with V7 dry sand making equipment

at the meeting, the ready mixed concrete branch of China concrete and cement products association cooperated with relevant experts and enterprises to conduct technical exchanges and discussions on how to prepare artificial aggregates of fine quality mechanism sand and stone (including construction waste and artificial aggregates due to the complexity of the intelligent control system of the pressure testing machine) and the application technology of machine-made sand and stone

relevant leaders and staff from the construction project management department; Responsible persons and technical and quality management personnel of ready mixed concrete companies, concrete components, cement products production enterprises and admixture enterprises; Principals and technicians of engineering construction, supervision, construction and other units, and concrete technology R & D personnel of colleges and universities and scientific research institutions attended the meeting

the on-site technical exchange meeting on the production of machine-made sand and gravel artificial aggregate and its application in concrete

among them, guests such as the president of Beijing Concrete Association, the Secretary General of China sand and gravel Association, the doctor of China Academy of construction Sciences, the vice president of Jidong Cement branch, the vice president of Huzhou xinkaiyuan gravel Co., Ltd., the engineer of Beijing Municipal Road and bridge group, and the professor of Tsinghua University made wonderful keynote speeches, President Zhou, the leader of Nanfang Road Machinery Co., Ltd., vividly introduced the dry sand making equipment of Nanfang Road Machinery Co., Ltd. to the guests at the meeting

at the meeting, experts analyzed the tensile testing machine fixture sprayed with emery. As natural sand and stone is a local material, it has risen to yuan/cubic meter due to resource and transportation constraints, and has become a hot product in the industry. Moreover, resources are rapidly decreasing, and natural sand in some areas has been nearly exhausted. In order to protect river embankments and dams and protect the ecological balance, local governments have stipulated that some rivers are strictly prohibited and limited exploitation. Since the 1960s, the civil construction engineering of hydropower system has begun to use local materials, conduct research on the production and application of machine-made sand and gravel, and began to be used in engineering. The famous hydropower projects such as the Three Gorges and Xiaolangdi are all artificial sand and gravel construction, which has a history of more than 50 years. The production line with the largest annual output is also in the hydropower system, reaching 30million tons/year. Rock, pebble, mine tailings or industrial waste residue particles are processed through soil removal, mechanical crushing, shaping and screening. The particle size is less than 4.75 mm. At present, machine-made sand is also produced and used in some areas of the country, and industrial waste residue, construction waste and waste rock are also processed and utilized in some areas. In recent years, this industry has become a traditional and new entrepreneurial field. With the requirements of infrastructure construction technology and the development of high technology, there are higher requirements for the quantity and quality of sand and gravel. We should actively promote the use of machine-made sand to alleviate this prominent contradiction. Machine made sand and gravel has become the main development direction and industrial subject of the transformation and upgrading of the industrial structure of the sand and gravel industry, and the construction and development momentum of machine-made sand production base is promising

on site communication

the dry sand making equipment of Nanfang Road Machinery Co., Ltd. became the highlight of this meeting, and many manufacturers gathered to consult and understand. Through this meeting, Nanfang Road Machinery Co., Ltd. showed the experts and scholars in the industry and the majority of users the complete set of international high-level environmental protection sand production process equipment
