The cone crusher came out more than a hundred years later than the roller crusher, more than twenty years later than the gyratory crusher.
Before the cone crusher was unveiled, the hydrogen-oxygen process had developed greatly in the early twentieth century. It required to provide a finer product than the gyratory crusher and jaw crusher. In this case, in addition to roller crushing. In addition to the medium and fine crushing equipment, there are also coarse crushing crushers for fine crushing equipment. For example, the Brow-Hell Improvement crushing plant built in 1931 used a 48-inch gyratory crusher for coarse crushing, with the mining technology. Continuous development, cone crushers are also divided into several types.
The emergence and development of the cone
In 1927, a cone-shaped cone crusher (hereinafter referred to as a slow cone cone crusher) was officially used in industry. This type of cone crusher has a Simon standard and a short cone crusher and a spherical cone crusher.
Soon, the steeply inclined compression cone crusher was also introduced. The crusher was called a compression rotary crusher. In essence, the crusher was improved on the basis of the gyratory crusher and used between medium and fine crush. The crusher has the same shape and structure as the short-shaft gyratory crusher. It has a steep taper surface, a small discharge port, a short spindle, a large stroke and a high speed.
By the end of the 1950s, the cone crushers manufactured in various countries began to use hydraulic technology extensively, which further improved the cone crusher. At this time, the slow cone crusher used hydraulic pressure or the original spring overload protection device and the tapered surface. Air pressure regulating discharge port device, hydraulic overload protection device and hydraulic locking device.
At the same time, the steep cone cone crusher also adopts hydraulic technology while retaining the original steep moving cone surface. According to the location of its hydraulic setting, it can be divided into bottom hydraulic support or top hydraulic suspension. Cone crusher. Since the regulation of the discharge port and the overload protection device adopt a unified hydraulic system, the structure is simple.
In the 1970s, the cone crusher made progress in two aspects. One was the large cone crusher of 3050 mm, and the other was the steep cone and cone cone crusher that can produce ultrafine materials. The latter has a new type of crushing cavity structure, the spindle is short, and the material of 4 mesh can be obtained.
The cone crusher consists of the above two main types, but other types, such as the multi-cylinder hydraulic crusher without gear rotation, the multi-cylinder crusher is actually only used for the locking device, and can not be combined with the bottom single-cylinder hydraulic breaker. The top single cylinder hydraulic breaker is comparable.
