Abstract

Keyword vertical compound crusher crush discharging pin-size

The design of complex parameters of the main vertical to a crusher and structure .The article talks about a broken theory .And described the traditional technical specifications to a crusher and the scope and their deficiencies.

Vertical a crusher is based on the improvement of the hammer, set in a crusher and return to a crusher and conical so on the merits of the broken equipment, materials and to receive the impact on airs, grinding etc.Apply to the crushing medium hard coarse-grained material is an ideal of thin, cracked equipment for metallurgy, building, mining, chemical, electricity, coal industry materials for secondary crushing and grinding, cutting the ground before next to the mill, grain output increased from 35% to 45%.

The design of the composite vertical to a crusher and the vertical to a crusher and the pendulum type to a crusher; the production capacity has been much improved. The granularity of material sex got a good that the materials have been effective, this is a production of practice to permit. But because of the new machine, so it has not yet have the mature calculated to compute accurately but break the traditional machinery on the basis of production and practice, a rough estimate.
