In view of the development trend of the mining machinery industry in the next few years, experts said that the next few years will be the rapid growth of the world mining machinery industry for a few years, which is even more important for domestic mining machinery and equipment manufacturers. How to harden internal strength, speed up the research and development and innovation of its own products, establish a comprehensive after-sales service network, and accurately grasp the market pulse, organize production and allocation of resources according to market demand, optimize product structure, open up markets, increase revenue and reduce expenditures faster. Better development has become a challenge for the domestic mining machinery industry.

In China's economic construction and social development, the mining machinery industry has an important position as the pillar industry of the national economy. As a construction and mining equipment and raw material deep processing equipment, mining machinery provides a large number of basic industrial products and energy for various industries (such as mining, energy, transportation construction, industrial raw material production, etc.), which greatly protects the national economy. The health is growing rapidly. The crushing equipment is an important part of the mining machinery, including dozens of different equipment such as jaw crusher, impact crusher and cone crusher.

The crushing equipment not only plays a huge role in the deep processing of raw materials in coal, electric power, chemical industry, building materials and other industries, but also provides efficient and reliable technical equipment support for the construction of railways, highways, hydropower and municipal engineering. Therefore, in-depth study of the development status of international and domestic mining machinery industry, the trend and trend of industry technology development, especially the cutting-edge technology of crushing plants, to further develop and improve the level of mining machinery manufacturing in China, for the development of coal, metal and non-metal mines More high-quality, high-efficiency equipment with international advanced level is of great significance to meet the needs of the national economy for energy and raw materials.

In view of the production characteristics of today's mining industry, the development trend of mining machinery and equipment such as crushers is large-scale, digital intelligent and ecological energy-saving. The domestic mining machinery manufacturing industry has undergone two changes in its development process. First, product development has changed from imitation to independent innovation; second, economic operation has changed from extensive to efficient. MPEX Corporation aims at the market, builds brands and enhances market competitiveness. According to the company's own positioning, carefully build the brand, use its own fist products, expand market space, and enter the international and domestic markets. At present, many products such as mobile crusher, mobile screening machine and mobile conveyor produced by MPEX are widely used in large projects such as mining, metallurgy, building materials and water conservancy, creating greater value for customers. At the same time, MPEX Corporation also did not forget to increase the management of the corporate marketing department, enhance technical support and other services, the company's services throughout the product design, production, sales, after-sales and other services throughout the process, to solve problems for enterprises, to consolidate old users , develop new users.

MPEX Corporation closely meets the actual production needs of domestic mining, chemical, road traffic construction and other industries, with market demand as the most fundamental basis, with strong research and development strength as technical guarantee, to represent the frontier of industry technology development. The high-performance, highly integrated crawler mobile crushing station and integrated solution technology provide first-class products and excellent services for users in the mining and construction industries at home and abroad.

For large-size garbage, some citizens are reluctant to clean up, or they are too troublesome. Therefore, large pieces of garbage are discarded everywhere on the roadside, in the corner of the community, in the corridors of the building, etc., which not only affects the sanitation environment, but also affects the travel of other residents. Waste dumps have also become a hiding place for cockroaches, mice and mosquitoes, posing a safety and health hazard. How to deal with these large pieces of garbage has become a problem for the people to scratch their heads.
 

Large-scale demolition and remodeling has also brought a lot of large-scale garbage that is difficult to handle. Many old sofas, broken mattresses, old wardrobes, and even some scrapped electrical appliances are randomly discarded in the public area "homeless." In the "regeneration base", there is also a "magician" - a large waste dumper. Through the dismantling of the machine, the garbage is decomposed into wood, bamboo, sofa, etc., and the valuable part will be supplied to the relevant manufacturers for resource utilization. The relevant person in charge has calculated such an "account": At present, the cost of construction waste in the recycling base is 8-15 yuan/ton, and the price of the recycled construction waste is 18-22 yuan/ton, and the actual profitable 5-8 Yuan/ton, the annual direct economic benefit can exceed 300,000 yuan.

What is big waste?
 

According to the Technical Requirements for Large-Scale Garbage Collection and Utilization, bulky waste refers to waste that weighs more than 5 kilograms or has a volume greater than 0.2 cubic meters or a length of more than one meter and is highly integrated and needs to be disassembled for reuse or treatment, including Waste household appliances, furniture, decoration waste, etc.
 

Those large pieces of garbage that have been discarded, if you want to regain value, need to go through MPEX's large-scale garbage mobile crusher.
 

MPEX will introduce large-sized garbage mobile crushers with mature technology, advanced design and reliable quality.
 

MPEX Large Waste Mobile Crusher is a large-scale domestic garbage mobile crusher designed for the crushing of large pieces of garbage materials. It can mainly crush and reduce large pieces of large pieces of sofa, mattress, furniture, wardrobe and other waste.
 

MPEX large pieces of garbage mobile crusher features:
 

※Imported alloy cutters have strong impact resistance and the broken metal cutter does not break.
 

※ After the tool wears, the advanced tool welding repair technology is used to realize the repeated use of the tool, which greatly reduces the maintenance cost of the tool.
 

※The inner hole and the main surface of the tool are designed in a hexagonal shape to achieve uniformity of the force applied to the tool.
 

※The tool is arranged in a spiral to achieve efficient cutting.
 

※ For large materials, equipped with hydraulic automatic feeding system.
 

※The bearing is four-fold sealed, which is effective waterproof and dustproof.
 

※ No mesh control output size to improve crushing efficiency.
 

※ The motor current is monitored in real time. When the load is overloaded, the tool axis is automatically reversed to protect the motor.
 

The process of dismantling and disposing of large-sized garbage is a process of turning waste from large to zero and turning it into a treasure. The recycling of recyclable parts and materials in large pieces of waste can realize the maximum resource utilization of waste.
 

After the test, the large pieces of garbage that cannot be refurbished and reused will be disassembled and disassembled for overall disassembly, and the integrity of components and parts will be maintained as much as possible during the disassembly process.
 

Recycling of reusable components and parts
 

At the same time, the hazardous materials and parts are identified and dismantled. During the dismantling process, the dangerous materials and parts must be protected from damage and leakage, and stored in an appropriate manner and treated in a harmless manner.
 

Parts that are not directly reusable need to be further disassembled to recover the renewable materials.
 

Recycling of parts and materials must comply with certain requirements when recycling, and cause secondary pollution to the environment during recycling and cause health damage to the human body.

MPEX serves the global mining and aggregate industries with most advanced tracked mobile crushing and screening equipment, and integrated solutions. Our tracked mobile crushers, screeners and conveyors have served customers in 66 countries, and win customer trust, even gain recognition of top 500 companies.

We all know that any mining machinery and equipment has a certain service life, and the mobile jaw crusher is no exception. After a long period of operation, the jaws, bearings, jaws and other parts of the mobile jaw crusher will wear out, which will require To replace the new spare parts, this paper focuses on the analysis of the causes of wear of the mobile jaw crusher tooth plate.

The main reason for the wear of the tooth plate is that the abrasive material slides shortly relative to the tooth plate, and the cutting metal causes the grinding and the repeated extrusion of the abrasive material to cause multiple deformation of the tooth plate material, resulting in fatigue degranulation of the metal material.
 

Wear failure process
 

(1) The material is repeatedly extruded and chiseled, and micro-cracks are formed in the surface layer of the tooth plate area or at the root of the protruding portion of the extruded metal, which is continuously extended to connect with the micro-cracks, causing the surface metal material to fall off and form wear debris.
 

(2) The material is repeatedly squeezed, causing the metal material of the tooth plate to be partially fractured or turned up, and the broken or turned up part is detached from the material that is crushed and impacted to form wear debris.
 

(3) The material slides shortly with respect to the tooth plate, and the cutting tooth plate forms wear debris.
 

Therefore, the control of the tooth plate wear from the wear-resistant material is mainly hardness and toughness, the material is hard, the material is pressed deep, the material deformation is small, and the cutting amount of the material to the short-range sliding of the material is also small. The equipment should be selected with good toughness and strong resistance to fracture. It can eliminate brittle fracture during extrusion and impact, and improve the ability of fatigue deformation and cracking.
 

The mobile jaw crusher produced by MPEX adds a variety of alloys to the composite modification on the basis of high-manganese steel and multi-alloy steel, so that the overall structure of the product is very dense, the chemical composition is reasonably matched, the toughness is strong, and the hardness is high. Good mechanical properties were obtained. Under the same working conditions, the new alloy high manganese steel tooth plate is more than twice as long as ordinary high manganese steel material, and is trusted by users!

Florida Beach, Mexico - Tom Garcia watched with horror as the fingers of the water were pushed inland across the beach and began to fill his home.

His wife handed him a drill and Garcia closed his front and back doors with screws. But soon, the storm from Hurricane Michael rose to his chest. His dog floated on his bed. He said that because the water outside the glass rose higher than the water in the house, he went all out to close the sliding door.
 

"This is a matter of life and death," Garcia said in tears as she walked through the destruction of Mexican beaches on Friday.
 

Michael is one of the most powerful hurricanes ever landed in the United States, and the 1,000-bay Gulf Coast community is in its bullseye on Wednesday. Although most residents fled before the storm, others still faced hurricanes.
 

They barely fled because the house was smashed from the foundation, the block was submerged, broken planks, sheet metal and other debris flew through the air.
 

The 57-year-old restaurant chef Hector Morales never considered evacuating. He grew up in Puerto Rico, where he said "you learned how to weather the storm."
 

His mobile home is not on the beach. But when the hurricane came to the inland, the dock was behind the dock at the back of his house. Soon, Morales said his mobile home began to float.
 

"Water continues to fly so fast, it starts coming in from everywhere," he said as he sat on a broken staircase on the mattress and other storm debris. "I have about 3 feet of water in my house. I decided to jump."
 

He and his two neighbors eventually spent six hours crawling into a fishing boat tied to a palm tree.
 

"I lost everything - my clothes, my wallet, my credit card," he said. "But I did it."
 

Bill Shockey, 86, refused when her daughter begged him to leave Mexico Beach. He said he didn't want to leave his Gone with the Wind dishes and antique dolls. So he hid those valuables in the closet and went to the new two-story house next door to his daughter.
 

Hope to fade
 

With a cigar-filled pocket and his cat named Andy, Shockey watched the hurricane roll from the upstairs bedroom. The wind shredded the roof of his single-story home. The water almost rose to the top of his garage door. A neighbor was pushed down the street across the street.
 

Is he afraid? "Worry, I think, it's more like it," Shockey said.
 

US officials said the death toll in the storm reached at least 18 on Saturday night and is expected to rise as it hopes to find more people alive.
 

“Unfortunately, we are entering a recovery model,” said Panama City’s fire brigade commander Alex Baird, one of the areas damaged by hurricanes in the coastal areas of Florida.
 

"At sunrise, we will start searching again," Baird said. "We hope we can find more (survivors), but it is increasingly doubtful."
 

President Donald Trump is expected to visit Florida and Georgia earlier this week to check for damage, and the White House said on Saturday night that the president is fully committed to helping state and local institutions achieve recovery.
 

The disaster is ruthless, and the world is affectionate. Homes destroyed by the hurricane, MPEX can help you rebuild your home. For buildings destroyed by hurricanes, MPEX mobile crusher can break up these construction wastes for recycling. Rebuild your home and let MPEX do your part.
