IMPACT CRUSHER

FIELD OF THE INVENTION

Our present invention relates to an impact crusher of the type in which a rotor is Provided with

crushing elements which cooperate with impact members which cooperate to form a crushing gap and to

an impact member assembly suitable for use with such a rotor. Moro Particularly the invention relates to

an impact crusher comprising a rotor and two or more impact members interconnected to form an

adjustable impact member system，a first impact member being mounted pivotally around a first

horizontal axis by way of at least one drive means，and having a second horizontal axis on which a

second impact member，pivotal by way of at least one drive means，15 provided.

BACKGROUND OF THE INVENTION

An impact crusher for crushing material of various consistencies is known for example from DE

23 31 729 Al in which the impact plates are interconnected in articulated manner to form a coherent

composite pivotal impact member，each of the interconnected impact plates deriving adjustable support

individually from the housing. The impact plates may have impact surfaces which are at angles to one

another or arc stepped along the path of the material as it 15 entrained from the inlet side of the machine.

The principles of such machines have also been developed in the Chemical Engineers Handbook，Perry and Chilton，5th edition，McGraw Hill Book Company， New York，1973，at Chapters，pages

19 ff.

This known impact crusher，just like impact other crushers of the same genus，suffers from the

substantial drawback that the upper impact member，provided downstream of the machine inlet yields

outwardly due to foreign objects which cannot be crushed entering the machine，so that the crushing gap

between the rotor and the lower impact member is decreased to such an extent，due to the upper impact

member pivoting outwardly，that a risk arises of foreign objects getting wedged between the rotor and

the impact member,leading to possible damage to the rotor and/or the impact member，so that the

continued operability of the installation can no longer be ensured.

OBJECTS OF THE INVENTION

It is the principal object of the present invention to provide an improved impact crusher such that

the damage which can be caused by the entry of a noncrushable foreign object can be minimized.

Another object of the invention is to provide an improved impact crusher which is free from the

drawbacks of earlier devices or apparatuses of this type and particularly the drawbacks mentioned above.

Still another object of this invention is to provide improved impact assembly for a rotor-type

crusher or breaker whereby drawbacks which could have resulted in down time can be avoided.

SUMMARY OF THE INVENTION

These objects are attained，in accordance with the invention in an impact crusher of the type in

which a rotor and two or more impact members are provided along the path of the crusher members of

the rotor to form an adjustable impact assembly. A first impact member is pivotally mounted at a first

word文档 可自由复制编辑

horizontal axis and a second impact member is pivotally mounted on the first impact member by a

second horizontal．

axis and respective drive means is provided for controlling the displacement of the impact

members．

According to the invention，the horizontal axis pivotally supporting the second impact member is

provided in the 5 region of that end of the first impact member which is remote from the first horizontal

axis and the second impact member comprises one or more levers．

It is an important feature of the invention that due to the specific arrangement of the point of

engagement for the 10 support and the point of articulation of the lower impact member to the lever，the

crushing gap between the lower impact member and the rotor is enlarged in the event of the upper

impact member yielding due to foreign object interference．

Because of the geometrical relationships with regard to the cylinder hinge point and the axes of the

impact members，the edge of the lower impact member closest to the rotor is moved automatically in

such a manner during opening of the impact member, for which purpose a housing member is

20swibeled around the pivotal axis，that the edge does not collide with the rotor or the beater bars，thus

preventing damage．

Different drive means，preferably hydraulic cylinders，25 may be emp10yed in Order to adjust the

two impact members．

More particularly， the impact crusher can comprise:a housing; an impact crusher rotor rotatable in

the housing about a horizontal rotor axis; and at least one impact member assembly in the housing

adjustable relative to the rotor，the assembly including: a first impact member having impact surfaces

juxtaposed with the rotor and pivotally mounted in the housing for movement about a first horizontal

pivot axis to shift the surfaces toward and away from the rotor，a first drive means articulated to the first

impact member for angularly displacing the first impact member about the first horizontal pivot axis，a

second impact member having impact surfaces juxtaposed with the rotor and pivotally mounted in the

housing for movement about a second horizontal pivot axis on the first impact member at a location

remote from the first horizontal pivot axis to shift the surfaces of the second impact member toward and

away from the rotor，at least one lever swingable about the second horizontal pivot axis and operatively

connected with the second impact member for pivotally displacing same about the second horizontal

pivot axis，and second drive means articulated to the lever for angularly displacing the second impact

member about the second horizontal pivot axis．

The impact crusher according to the invention is characterized by a particularly high operational

reliability and，therefore，a particularly long useful life due to the advantageous arrangement of the point

of engagement for the support of the lower impact member．
