Jaw Crusher History
Americans EW Blake (Black) designed and manufactured the world’s first jaw crusher.
Its structure in the form of dual-elbow-plate (simple oscillating type) jaw crusher.
The crushing machine is the modern steam engine and electrical power machinery, etc., after a gradual improvement and extension have created. Appeared in 1806 with the steam-driven roller crusher; in 1858, the United States, Blake invented the broken rock jaw crusher; in 1878, the United States has developed with continuous action cycles crusher broken, its production efficiency is higher than for intermittent Broken action jaw crusher; in 1895, the United States, William invented a low energy impact crusher.
Americans EW Blake (Black) designed and manufactured the world’s first jaw crusher. Its structure in the form of dual-elbow-plate (simple oscillating type) jaw crusher. As the jaw crusher has a simple structure, easy to manufacture, reliable operation, convenient maintenance and the advantages of smaller size and height. Is still widely used in crushing hard, medium hard, soft ores and a variety of materials, such as various minerals, solvents, slag, building stone, marble and so on.
Commonly used jaw crusher crushing machine is 4 ~ 6, and small jaw crusher can sometimes reach 10. Large and medium-sized crusher feed force of up to 1000 ~ 2000mm, size of their products up to 20 ~ 250mm, small crusher and a new crushing using jaw crusher products can be derived from a number of more detailed. Jaw Crusher can be used for primary crushing operations can also be used in fine job. In particular, be used for underground crushing operations and in small mobile crusher unit. Jaw crusher works by means of the activities of jaw plate periodically close to or away from fixed jaw plate of the swing movement into the crushing chamber so that the material be squeezed, splitting, bending and impact the role of fragmentation. Broken material by weight or jaw thrust plate swing down when discharged from the discharge port. Jaw plate in accordance with its trajectory, structure, form, movement, and moving jaw jaw hanging bracket support in different ways, jaw crusher jaw plate is to use two pairs of materials, the role of compression and bending, coarse crushed or broken in a variety of hardness of materials a broken machine. His broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials Jibei broken jaw plate when the two left the mouth of nesting material is less than block from the bottom of the discharge. Its crushing action is carried out intermittently. This crusher due to simple structure, reliable and can be broken advantages of hard materials are widely used in mineral processing, construction materials, silicate and ceramics industries.
The 20th century, 80 to 20 years, crushing 800 tons of material per hour, a large jaw crusher feed size has reached approximately 1,800 mm. Commonly used jaw crusher with elbows and single-board the two brackets. The former is only at work, moving the jaw to make a simple swing arc, it is also called a simple swing jaw crusher; the latter making a circular swinging up and down movement and also to make, it is also called the complex swing jaw crusher.
Zhengzhou Kefid Machinery Co., Ltd as a domestic leader in crushing and screening equipment, complete sets of equipment manufacturers and providers of a comprehensive program for processing of aggregate concentration and developed an efficient, energy-saving broken equipment. And medium-sized jaw crusher which is one of my company’s leading products, especially in the design and production of large jaw crusher, the leader at home and abroad are at an absolute level. Jaw Crusher is the industrial and mining production, one of the most commonly used crushing equipment, mainly for compressive strength of not more than 320 MPa in a variety of materials, broken, rough broken operation, with broken than large, high output, the product particle size uniform, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics.
In recent years, the company developed the mobile crushing station, high-performance vertical impact crusher (sand making machine), hydraulic cone crusher, large-scale Impact Crusher and other products has reached international advanced level, access to dozens of national patents, national, provincial and municipal science and technology awards. Products have been widely used in mining, building materials, metallurgy, transportation, hydropower, coal, chemical industry, environmental protection and other fields.
