Reform and opening up to now, China's iron and steel industry has been rapid development of China's current steel production has leapt to the world. After the rapid development in recent years, the steel industry is gradually emerging out of natural resources and lack of t is too large output of energy consumption, environmental pollution and other contradictions. Scrap iron and steel industry resources as a "second mining", with energy conservation, reduce pollution, protect the environment, recycling, etc., its impact will grow. In recent years, the supply of scrap on the rise year by year, and its role gradually expanded so that the resources have been further recycling.
So for the scrap processing industry, processing of larger crushing machine, higher productivity, the most important and most crucial is its debris can be removed, if accompanied by the appropriate sorting equipment, then the steel will be more harmful to The mixed non-ferrous metal scrap inside the sorting out to be a very pure high-quality ferrous raw materials. Broken machines as their primary crushing equipment, mining industry occupies an important position is the basic mining equipment.
First, an overview of Crusher
The world's dominant pop and the breakers, mostly in the United States on the basis of Newell's derived, the possession of nearly Qi Cheng, such as Germany's Lindemann, Japan's Fuji vehicles. Crusher creation and development, and scrap development of the industry is closely related to the very beginning to deal with only some thin material, with the deepening of understanding, as well as the manifestation of the superiority of broken steel, various specifications Breakers continually develop, the use of range more widely.
Second, the principle and mechanism of Crusher
The core principle is to use a hammer hitting the basic principles of high-speed high-torque motor driven by the host rotor rotation hammer blows into the capacity of cavity material to be broken, through the formation between the liner and the hammer space, will be broken into a complex tear of the broken material and conforming to specifications.
According to crusher working conditions can be divided into dry-type system, wet system. Dry-type system is mainly refers to the broken material to go through the air swing sorting system separates the metal and non-metallic, while the entire system is equipped with dust removal device. Wet system is broken at the same time by spraying water, and in sorting at the same time tricking cleaning. Semi-wet systems only broken when necessary, to conduct a small amount of water spray to prevent the dust, there is no cleaning.
3, prototype and technology introduction
United States is the earliest to introduce the company's 4000-horsepower Newell crusher, uses a semi-wet systems, put into production in 1996 from the current use of situation, its production capacity of 100 tons / hour, have more surplus, often in downtime and other material state, equipment idle is higher. And a great one-time capital investment. Based on the user requirements, the key core technology really started to introduce, then the power of Emperor Machine Tool Co., Ltd. Hubei initiated. Once they start to engage in serious market research, analysis of domestic and international market conditions to determine the suitable to China's national conditions, to achieve both economic and meet the market demand models.
From the technical analysis: the main structural features of crusher is the body using extra-thick steel plate bracing to strengthen the structure to ensure strong broken overload the machine requirements, but also directly part of the use of force "assembled" structure to further improve the machine reliability. Linings, hammer with special wear-resistant materials, improved service life; and the activities of the hammer used to install the structure in the event of non-broken material being diverted to crushing machine, you can avoid the rejection over the same time, tertiary crusher set to open Emission of non-broken doors to exclude it from the machine, thereby reducing the extent of the damage the machine; with a hammer and the sleeve, and high-speed rotation of the spindle and the unique structure of the bottom grid plate is a high production efficiency protection.
Hydraulic dual-roller rolling machine at its core function of the feed pre-crusher machine, which can form the shell of a larger size class and light metal components, the whole is compacted to form smooth entry into the crusher feed throat of the scrap materials, thus extending the scope of crusher processing materials. At the same time improving the production efficiency of crushing machine plays a vital role. I am an expert from China Manufacturers, usually analyzes all kind of industries situation, such as glass salad plates , hand painted platter.
