Scrap crusher is a kind of crushing machine used to produce scrap material, mainly used to scrap cars, scrap appliances and light scrap steel machine.
6. Power consumption per ton of molten steel is reduced.
Energy needs:
The structural characteristics of the crusher are roughly as follows: Large Steel Crushing Equipment,Steel Crushing Equipment on Sale,Scrap Steel Crushing Equipment Shuangxing Mechanical Equipment Co.,Ltd , https://www.gyshuangxing.com

Scrap crusher after the crushing treatment of scrap has the following characteristics:
1. Neat material shape and similar specifications;
2. High bulk density;
3. Less attachments;
4. High purity.
The advantages of using broken steel for steel smelting are as follows:
1. High yield;
2. The chemical composition of molten steel is stable and the content of sulfur and phosphorus is low;
3. Shorten smelting cycle;
4, furnace lining life extension;
5. Reduce air pollution and slag;
The effective recovery and utilization of scrap metal resources can greatly reduce the exploitation and consumption of natural mineral resources, so as to reduce land occupation, reduce total energy consumption, save investment, protect the ecological environment and improve labor production benefits. Especially in the extreme consumption of natural mineral resources and increasingly scarce today, scrap metal resources in the world economy. The position of sustainable development strategy is more and more prominent. Since 2000, all countries in the world have been actively and effectively recycling scrap metal resources, in order to properly curb the long-term transition of mineral resources and energy consumption. Scrap iron and steel is the only raw material that can replace iron ore in the production of iron and steel.
1) the shell of the main engine is made of extra thick steel plate with a high manganese cast steel lining, which can be replaced;
2) there are 11 steel discs mounted on the horizontal shaft in the rotor of the main engine. There are 6 pin shafts distributed around the circumference of the steel disc and 10 hammer heads suspended in the axial direction.
3) the spindle is supported by ball bearing, and the circulating oil is forced to lubricate and cool, and equipped with temperature sensor;
4) the feeding port is equipped with super strong double-barrel feeding device, which is rotated in the same direction, and can gradually flatten the large loose materials and feed them into the machine. The speed of the drum determines the feeding speed, which is controlled by the motor load current feedback of the host, realizing automatic regulation to ensure that the host is in the best load state.
5) after the unbreakable material enters the machine, the operator can open the discharge door to discharge it from the machine to avoid damage to the crusher.
The working principle:
Scrap crushing processing is the use of crusher scrap crushing, the use of sorting system after the broken scrap separation to get pure high quality scrap processing method. Its working principle is that under the continuous drive of high speed and large torque motor, the hammer head on the rotor of the crusher takes turns to strike into the cavity scrap, under the strong impact, scrap is torn and squeezed into a certain size of broken steel, and then through the sorting equipment processing, you can get high purity quality broken steel.
2017 plant protection drone development needs to boost confidence
[ China Agricultural Machinery Industry News ] The development of drones has been in a hot state for the past few years, and the application of drones in the field of plant protection has also been carried out in full swing. In the past year, it can be said that it is a plant protection drone. In the first year, many drone manufacturers, flight defense service providers, and agricultural capital merchants were active in the industry, contributing their own strength to the plant protection industry. However, in this great situation, there are still some "sorrows" caused by various reasons.
2017 plant protection drone development needs to boost confidence
Boss Zhu bought a farm plant protection drone from a small drone manufacturer early last year. Since he has operated other types of drones in the past, the family has also contracted several hundred acres of land. After practicing for a period of time, Zhu Bo decided to expand the contract size and prepare himself and his brother to use the drone to fight drugs in the field. Just a few times at the beginning of the operation, the process was smooth. After more than a month, I didn’t know what the reason was. Several parts of the drone were damaged one after another. Zhu boss took the parts and asked the manufacturers to provide after-sales service. The manufacturer told Zhu Boss The parts need to be returned to the factory for a new one, so that Zhu boss will go home and wait for news. A few days later, when Zhu Bo and his brother found the manufacturer again with unusable drones, the factory had already gone to the building.
As the captain of a professional plant protection drone, the captain set up a small drone flying defense team of about ten people. Together, they made some money and purchased three plant protection drones. Peasants and large-scale farmers who need to fight drugs, but because the local busy season is very limited, they spend only two or three months intensively. At other times, they need to find jobs in other parts of the province or in other provinces. But in many cases, even if it is able to work across provinces, it is impossible to get reliable information in time. In addition, the needs of farmers may change at any time. Sometimes the flight defense team is already on the way, but they are told that the other party has changed. Because there was no contract signed in advance, the captain only had a sigh.
In the case of Zhu Boss and the captain, there are still many, many in the plant protection industry. I thought that I could make a fortune in the first year with the plant protection drone, but I didn’t want to lose my wife and the soldiers. Whether the after-sales service of the plant protection drone can keep up with whether it can find reliable work after purchasing the aircraft, how to use the aircraft when it is idle, what should be done to the farmers who do not reason and do not fulfill the contract terms, the dealer must Don't buy airplanes yourself... these are all issues to consider.
At the same time as these kinds of problems are exposed, some platforms for providing drone flight defense services have appeared in the industry. For example, farmland butlers are one of them. The flight defense team has settled in the farmland butler platform and can choose the right platform on the platform. Orders for the situation, even for inter-provincial orders, are reliable job information. Inter-provincial operation means that the flight defense team's annual operation time is lengthened, and the aircraft idle time is reduced. The agricultural capitalists who want to transform can also easily transform to the agricultural service providers by becoming a platform partner, saving purchases. Unnecessary expenses such as airplanes and flying hands.
2017 has already begun, and I hope that this year will no longer be the "bad" year for anyone in the industry.
