Pneumatic zernodrobilka of DKR are intended for crushing of all species of grain crops, and also meal, melkokuskovy cake, pod and other fodder materials (humidity to 14% ).
Pneumatic loading and unloading of grain allows to do without use of the additional transporting equipment.
It is necessary to apply crushers in technological lines indoors. Crushers need to be used strictly as a part of the technological line:
- A crusher + the storage Bunker with system of aspiration BGP - 2,5;
- Crusher + Mixer of loose forages of SSK;
- Crusher + Cyclone razgruzitel.
Modifications of crushers:
DKR - reshetny crushers.
DKR - SI - special modification for crushing of straw and hay.

To Preim of a crusher shchestvo:
- high efficiency;
- reliability of a design of a crusher and high resource of working bodies in use;
- a pnevmaticheskay fence and unloading of a product that considerably reduces energy consumption and labor input of process of crushing;
- simplicity of service and use;
- possibility of replacement of working bodies;
- simplicity of adjustment of final fraction and quality of a grinding by means of replaceable sit also changes of a ratio of an air stream and the crushed product.
Dependence of productivity of crushers on diameter of an opening sit.

* Productivity is calculated on wheat with a bulk density of 750 kg/m3 and humidity of 14% . At uniform raw materials and previously cleared of metal and mineral impurity (stones, sand, glass) and installation on a crusher of a direct - flow cover.
Principle of action of a crusher.It is necessary, according to a compounding, the raw materials (wheat, rye, barley, oats, etc. ) humidity no more than 14% intended for crushing are absorbed by the ejector from a heap / burta. Further raw materials move on the flexible soaking - up hose through a separator in which the magnet (catching and separating metallomagnetic impurity is established) and cut for removal of impurity, then get to the crushing camera. Initial raw materials, getting to the camera, it is crushed by the rotating rotor with hammers and force rejected on sieve walls until the particle size distribution of particles appears less than diameter of openings of a sieve, and does not throw out them, under the influence of an air stream of the fan, in the case of a crusher (precipitator). Further the shredded product gets to the camera of the fan and is transported by the air stream created by the fan surrounded with the throwing - out path through an unloading branch pipe and on a flexible pressure head hose the precipitator moves or to the bunker of storage BGP - 2,5, or the SSK mixer, or during a cyclone.
