Cone Crusher Development History
Cone crusher is a common stone crusher machine, It was born in the early twentieth Century. Spring cone crusher is America () developed by the Simmons brothers, called the Simmons cone crusher. The structure of the spindle is inserted into the eccentric sleeve, driving cone rotary motion with an eccentric sleeve, dynamic cone lining plate and sometimes near and away from the fixed cone lining plate, so that the rock in the crushing cavity continuously by extrusion and bending and crushing. With large eccentricity, low oscillation frequency, small driving power, the crushed product size is not uniform, crushing effect is poor, the vibration, the spring is easy to damage. Adjustment difficulties with large screw adjusting discharge size, with spring group, overload protection, poor reliability. Over the years, in spite of the continuous improvement, perfect structure, but the change of its working principle and basic structure of small.
At the end of the 40’s, USA Allis Chalmers launched the first bottom single cylinder hydraulic cone crusher, is the steep cone development in the gyratory crusher of crushing machine. Hydraulic technology, the hydraulic adjusting discharge and overload protection, simplifies the structure of the crusher, reduces weight, improves the use performance. Because it depends on the discharge opening size control product size, product size, and uneven. On the water, the material containing mud blocking.
50-60’s, the French subsidiary of Dragon Babbitless company and Japanese Kobe Steel Ltd., launched the upper cylinder, the surrounding of single cylinder hydraulic cone crusher.
70-80’s Allis Chalmers company, based America bottom single cylinder hydraulic cone crusher in the introduction of high-energy hydraulic cone crusher. launched gyradisc crusher, the fourth section is suitable for crushing of hard materials, and the particle size is small, small eccentricity, crushing force is. Have also launched a super heavy short head cone crusher. Increase the power, spring, steel frame strengthening, increase the manufacture cost, for which the company introduced the Omni type cone crusher. In order to adapt to the flushing broken also launched WF wet type cone crusher. Babbitless launched BS704UF type super fine cone crusher. Bearing is replaced by rolling the eccentric sleeve, a motor, belt drive, and drive the moving cone swing, top of the single hydraulic cylinder device adjusting discharge and overload protection, feeding size -10mm, the particle size of the product -6.3mm 80%. The German KHD Humboldt Wedag launched the Calibrator cone crusher.
Since 90 time, America Cedarapids launched EIJOY type, MVP type cone crusher; USA launched a new generation of HP series cone crusher; Sweden Svedala company launched H series cone new crusher; Japanese Kobe Steel Ltd. launched the AF cone crusher and cone crusher: 2300ASC Russia Ural Machinery Research Institute and Mihajlovic Nobel Research & Design Institute to develop a new type of short head cone crusher, crushing machine is divided into two parts, according to the principle of material layer, the cavity of crushing material. Lower parallel region. Application shows that: the fine level content than the general cone crusher is increased by 5% ~ 10%. Lining plate of metal consumption is reduced by 20%.
