According to the Lancang Evening News, the second phase of China Shipping New Materials Project officially commenced on May 29 in the Cihu High-tech Zone in Maanshan City. It is understood that China Shipping New Materials Project is a contract signed by China National Chemical Corporation and Maanshan City in March 2011. The first phase of the project has been completed and put into operation. The second phase of the project, with a total investment of 1.5 billion yuan, will mainly build 100,000 tons of high-performance water-reducing agent, 80000 tons of dry powder water-reducing agent, 100,000 tons of cement grinding aid and 100,000 tons of concrete pumping agent, etc. Production line and supporting facilities.
Centerless grinding is also called centerless grinding, which is a kind of grinding process. There are two grinding wheels for the guide wheel and the grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the shim, and the grinding wheel plays a grinding role on the workpiece. Unintentional grinding belongs to the Zhou Mo method.
The heart grinding method is composed of three mechanisms: a grinding wheel, an adjustment wheel and a workpiece support (bracket), in which the grinding wheel actually performs the grinding work, the adjustment wheel controls the rotation of the workpiece, and causes the workpiece to enter the cutting speed As for the workpiece support, which supports the workpiece during grinding, there are several ways to match these three parts, except for stopping grinding, which is the same in principle.
