A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). Primary jaw crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. However, there are many exceptions to this general rule.

A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaws until it is small enough to pass through the gap at the bottom of the jaws.
Fujian Ningde "Golden Waterway" illegal sand mining diesel generator more than ban | diesel generator price / 2012-05-05
Ningde, May 5th, Baima Port, a state-level open port, is located in Xiabaishi Town, Fuan City, Fujian Province. It is an important component of the world-class natural deep-water port Sanduao. The waters in the port are wide, with small winds and waves, and the bottom sediment is silt, not frozen or silted. It is a natural sheltered harbor and is known as the “golden waterway†of Ningde in Fujian.
However, for more than 10 years, some people have been driven by illegal profits in Baima Port and its upstream and downstream seas. Illegal sand mining will not only cause collapse of the embankment, change the flow velocity and direction of the river water, bring great hidden danger to the embankment, but also affect the safety of maritime shipping, posing a threat to the life and property of the surrounding towns and villages.
A few days ago, the reporter went to a field survey of Baima Port in Xiabaishi Town, Fuan City.
Site: There is no fear of a sand-filled ship heaping sand piles along the coast
Reporters took a boat ride around the sea of ​​Baima Port. Through the hazy rain and fog, in the rain and fog, the illegal sand-picking ships in the Baima Port area had no fear of travelling and the coast was full of sand piles.
The local people told the reporter that the illegal sand-picking activities in the upstream and downstream waters of the Baima Port have been going on for more than 10 years, and sand mining is more frequent at night. Illegal sand-picking ships and law-enforcement officers took "mouse-cats" and once they were jointly enforced, most illegal sand-harvesting vessels took a risk ashore. Sometimes the law enforcement forces are insufficient and they are also besieged. As a result, they are revived after each blow. There are also many ships that have been parked in the port for a long time and are unlicensed and unlicensed, affecting shipping traffic.
Law Enforcement Department: Government Should Lead Multisectoral Joint Remediation
The relevant departments of the Marine and Fishery Bureau of Fu'an City have jointly enforced the law to crack down on the illegal sand extraction. However, why is the phenomenon of illegal sand mining in Baima Port still unfounded?
In an interview with the reporter, the director of the Marine and Fishery Bureau of Fu'an City, Chen Zixuan, said that at present, as long as there are reports, there are crackdowns, and all actions before the law enforcement are confidential, including the temporary adjustment of the route and destination of the action. Prior to this, people reported suspicions of “inside†or “shareholdings,†and they did not find out through the internal cell phone monitoring.
Chen Zixuan introduced that since 2011, the local fishery department has stepped up efforts to crack down on illegal sand mining, and has dismantled many tools for sand mining on site. However, Haisha belongs to minerals and is under the jurisdiction of the State Land and Resources Bureau. The illegal sand-picking vessels are also managed by the Maritime Affairs Bureau. The Bureau can only give a 30,000-yuan penalty from the department’s point of view, and has problems such as small authority and insufficient penalties.
“The Marine Department conducts daily inspections and inspections, and has repeatedly cracked down on it. From the end of 2011 to the beginning of this year, many departments including the Marine and Fisheries Bureau, the Marine Department, and the Forest Public Security Department of Fuan City have carried out special rectification actions.†Ningde Baima Port Maritime Affairs Department officials said that illegal sand-picking ships are highly mobile and driven by profits. Illegal sand-catchers may be behind the law-enforcement team, increasing the difficulty of enforcement. As the Department of Marine, it is only from the point of view of supervision that it will do its utmost to implement law enforcement. As long as the people have reported, it will receive feedback.
On how to further improve the effectiveness of the crackdown, he said that mineral resources should be managed at the source by the Bureau of Land and Resources. To be thoroughly combated, local governments should take the lead in organizing joint rectification of relevant units.
Town government calls for more effective remediation
Afterwards, the reporter called for an interview with Luo Yonghua, the deputy secretary of the party committee of Baishi Township. He said that the illegal sand-picking activities at Baima Port did exist for a long time and the situation was complicated; often, the law enforcement team disappeared as soon as it reached the sand-picking ship, resulting in repeated illegal sand-picking operations.
“As a local town government, all illegal sand mining is not allowed, which endangers the safety of people’s lives and property. We are members of law enforcement, but we have no law enforcement power, we can only persuade or report it. The masses have attributed many problems to grassroots organizations. In fact, we are innocent. "Luo Yonghua said that Haisha belongs to the management of the land sector and needs to be led by the higher level government to achieve more effective remediation. (Finish)
