Description

High efficiency doublestage rubbing crusher

Technical Field

The utility model belongs to the technical field of crushers, and particularly relates to a high-efficiency two-stage crusher.

Background

In the preparation process of medicinal materials, the large-sized medicines are crushed into smaller particles, so that the subsequent processing and treatment of the medicines are facilitated. Traditional crushing mode is by manual mashing, however mashing speed is too slow and large-scale mashing is not possible. In the need of mass production, there are machines for mashing medicines on the market, which are capable of rapidly pulverizing the medicinal material into particles of suitable size. In order to make the particles of the medicinal material reach the required size, the medicinal material needs to be crushed for a long time. Meanwhile, the existing crushing modes comprise jaw crushing and blade crushing, wherein the jaw crushing and blade crushing are used for crushing medicinal materials through extrusion, and the blade crushing is used for directly cutting the medicinal materials.

Because no matter what kind of crushing mode is used, the crushing to the medicinal material is once only accomplished, when the medicinal material has the lump or the medicinal material size is inhomogeneous, crushing mechanism can't quick broken, this can make the last meticulous part of crushing mechanism receive the damage, reduces life, also can make the granule of some medicinal materials too thin at the in-process of repeatedly crushing simultaneously, leads to broken granule size inhomogeneous.
