The working principle of the hammer crusher is to use a high-speed rotating rotor to drive the hammer of the crusher to impact the material, causing cracks on the surface, and then breaking along the fragile parts such as the bedding surface of the material. The crusher rotor is composed of a main shaft, a hammer plate and a hammer shaft. It is a key component of the crusher. Then how to choose the crusher rotor in the production process, Zhengzhou prosperous engineering experts have been studying for 17 years, and have experience in machine deployment:
The diameter of the crusher rotor is generally determined by the size of the crushed material. Normally, the ratio of the diameter of the rotor to the size of the crushed material is between 1.2 and 5. The value of the large crusher is small. The length of the rotor is related to the production capacity of the crusher. Generally, the ratio of the diameter of the rotor to the length is between 0.7 and 2. When the impact resistance of the material is large, the ratio should be larger. The rotation speed of the rotor affects the crushing efficiency and production capacity of the crusher, which is an important working parameter of the crusher. At present, the peripheral speed of the hammer crusher is 18-70m/s, the speed of the small and medium-sized crusher is 750-1500r/min, the peripheral speed is 25-70m/s, and the speed of the large crusher is 200-350r/min. The circumferential speed of the rotor is 18-25m/s.
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Natural Gas Mass Flow Meter, Natural Gas Mass Flowmeter, Natural Gas Coriolis Meter, Natural Gas Coriolis Mass Flow Meter, ATEX, IECEx & CE approved.
First, Sealand meter is certified by Zhejiang Institute of Metrology. To get such
certificate, Sealand has to send all models to Zhejiang Institute of Metrology
and all models are tested in their calibration lab. The lab is an ISO/IEC
17025:2005 standard lab approved by CNAS (China National Accreditation
Service for Conformity Assessment). CNAS is a member of ILAC (International
Laboratory Accreditation Cooperation).
Second, Sealand has its own calibration lab, equipped with METTLER
TOLEDO scales with accuracy 0.014% and the device extended uncertainty is
0.05%. The lab is also approved by Zhejiang Institute of Metrology. This
certificate will stay valid only for one year, Zhejiang Institute of Metrology will
send their professor to Sealand every year to check and make sure that the lab
is qualified still and then issue new certificate. During the production, each
meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
Finally, Sealand also gets ISO, CE, SIL, ATEX & IECEx. Sealand is the only
Chinese brand who gets ATEX & IECEx and it is from TUV SUD ( the most
authoritative institute for ATEX).
