Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a cement caking reducing mechanism, which comprises a housin 4, casing 4 is inside to be rotated and to set up

screening cylinder

1, 1 axis level of screening cylinder is arranged, casing 4 below screening cylinder 1 sets up the discharge gate 402 that runs through, casing 4's lateral wall sets up the feed inlet 401 of 1 inner chamber of intercommunication screening cylinder, 1 inside from last to arranging crushing mechanism 2 and secondary crushing mechanism 3 down in proper order of screening cylinder, feed inlet 401 highly is higher than crushing mechanism 2, crushing mechanism 2 includes the squeeze roll that a plurality of groups extruded each other and the level was arranged, the squeeze roll is parallel with 1 axis of screening cylinder, secondary crushing mechanism 3 includes the helical fan blade that a plurality of groups arranged along 1 axis of screening cylinder, helical fan blade's vertical the arranging of gyration axis, primary crushing mechanism 2 and secondary crushing mechanism 3 are fixed with casing 4's relative position.

A feeding conveyer belt 5 is arranged at the position of the feeding hole 401, the tail end of the feeding conveyer belt 5 extends to the upper part of the extrusion roller, and the feeding direction of the feeding conveyer belt 5 is consistent with the axial direction of the extrusion roller;
