The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.

According to CMEN, the price difference between LED lights and energy-saving lamps is rapidly narrowing. Compared with traditional light sources, LED lamps have the advantages of low energy consumption and long service life, but their high price has become an important reason for hindering the explosion of LED lamps. However, in the past two years, the cost of LED chips and packaging has dropped significantly, and the price of LED lights has also dropped significantly.
At the same time, overseas LED lighting source manufacturers Osram, Philips and Cree also launched low-cost LED lights this year. Among them, Cree and EcoSmart's LED bulbs replacing 40W incandescent lamps have dropped to US$10. The average selling price of LED lamps in the world has shown an accelerated decline this year.
As of June this year, the global average price of LED bulbs replacing 40W incandescent lamps has decreased by 20.41 since January 2012, while the price of LED bulbs replacing 60W incandescent lamps has dropped by as much as 33.90.
Compared with overseas markets, the price of domestic LED bulbs is generally lower. At present, the price of some domestic brands of 5W LED bulbs has dropped to 35 yuan (about 6.29 US dollars), and 13WCCFL energy-saving lamps with similar brightness. The price is about 11-15 yuan, and the sales price difference between LED lights and energy-saving lamps is rapidly narrowing.
