Working principle of hammer crusher: Hammer crusher mainly consists of frame, rotor, trapezoidal iron plate, bar grate, etc. And the frame consists of the upper part and the lower part, which are made of welded cut armor plate, while other parts are connected into one by bolts. So when big materials fall into the crushing cavity of hammer crusher, they will be broken into pieces by high speed rotors
Description of hammer crusher This product is new generation of reversible hammer crusher. Working principle of hammer crusher The main part of this hammer crusher is rotor. By adjusting the discharge grate plate, we can achieve the purpose of controlling the particle size
Working principle of hammer crusher The main working part of the small ammer crusher is the rotor with hammer. The raw material enters the crusher through the feeding port, and is impacted, impacted, cut and grounded by a high speed hammer. The clearance between the rotor and the shield plate can be adjusted according to different requirements
Materials was crushed by the hitting between rotating hammer and crushing plate. Motor and rotor shaft central shall keep straight in case of sleeve damage and heat. 4). The rotating part is on the right; the position can be adjusted as requirement
Working principle ofPC400x300 crusher hammer mill: Hammer crusher mainly consists of frame, rotor, support iron and grate bars. The rotors consist of the turn plate, pin shafts, and hammers which are grouped regularly in the main shaft. The motor drives the rotors to rotate quickly in the crushing cavity, and hammers spread outward as a result of centrifugal force from the rotation of the rotors

north korea is making millions selling sand. yes, sand
As part of their work at the Washington-based Center for Advanced Defense Studies (C4ADS), a nonprofit that analyzes and investigates security issues using big data, the two analysts keep an eye on traffic in North Korean waters and further afield in Northeast Asia
They do this because Pyongyang has been accused of selling coal and other valuable goods, sometimes in very big quantities, on the high seas to get around the prying eyes of customs officers, who must enforce United Nations sanctions on North Korea. Instead of moving goods into a port before trading, North Koreans supposedly just move them from one ship to another at sea and lie about their origins
But these ships weren't being used for running guns, dealing drugs, offloading counterfeit cash or trafficking endangered species, crimes North Korea is notorious for worldwide. They weren't even carrying coal, Pyongyang's most profitable export
They were being used to dredge and transport sand. That may seem innocuous, but North Korea is barred from exporting earth and stone under United Nations sanctions passed in December 2017. Trading North Korean sand is a violation of international law
Despite those measures, North Korea raked in at least $22 million last year using "a substantial sand-export operation," UN investigators said in a report released in April. One unnamed country supplied the Panel of Experts on North Korea, as the investigators are formally known, with intelligence claiming that Pyongyang sent one million tons of sand abroad from May 2019 until the end of the year.
The scheme was prominently featured in the panel's annual report. Alastair Morgan, who coordinates the UN panel that monitors sanctions on North Korea, said in an email that the report's authors decided "the large scale and the significance" of the operation warranted top billing
Kuo and Sung watched the ships for several weeks before noticing a pattern. All of those showing up in North Korean waters had a link to China. Some were flying Chinese flags. Others had Chinese names.
So they turned to satellite imagery, perhaps the most important tool among the growing open-source intelligence community. The photographs they got their hands on showed clouds of sand under what appear to be dozens of barges and dredgers, evidence that earth was being pulled up from the bottom of the sea en masse in North Korean waters
"We found plenty of reports from the early 90s to the present indicating that rather than this kind of being anything new, North Korea has always been exporting sand to a lot of its neighboring countries," Sung said.
Modern civilization is built on different types of sand. It's a key ingredient in concrete, glass and even the processors that power the electronic device you're reading this on. Humanity consumes about 50 billion tonnes of sand per year — more than any other natural resource on the planet except for water
