The vertical roller mill produced by our company
This kind of vertical roller mill have found their extensive application in the field of fertilizer, mining, building materials, chemical industry, metallurgy, thermal power, nonmetal, abrasive, brick, ceramic, steel, coal, etc. And the vertical mill can also be used to crush the block materials into the coarse powder (fine powder, the mixture of fine and medium sand ), such as cement (raw clinker), quartz, feldspar, calcite, gypsum, limestone, coal gangue, slag, talc, granite, feldspar, marble, barite, ceramics, glass, etc. And these are all high, medium, and low hardness materials with the Mohs hardness of below 9.5%.
During the operation of the Vertical Roller Mill, the reducer installed on the top of the main units will rotate with the central axis connected with the couplings .And then the central axis will drive the grinding roller cradle to rotate and the grinding roller installed on the cradle will roll around the inner surface of the grinding ring. And the materials will enter the feeding hopper from the side top of the machine and then be divided into two parts. And then the materials will scatter around the distributing plate which rotate with the central axis and then will be evenly entered the space between the grinding ring and roller along with the circle tunnel. And at last, the materials will be grinded and crushed by the roller and then be discharged by the outlet.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
