Embodiment 1

[0037] A cone grinding disc used in high-efficiency pulverizers for coarse and medium crushing of elastomers, as shown in Figure 1, as shown in the figure: 1 is the static grinding stator in the cone grinding disc, and 2 is the dynamic grinding rotor in the cone grinding disc , 3 is the water cooling cavity in the fixed mill, 4 is the water cooling cavity in the moving mill, 5 is the feeding thread with a notch, 6 is the transmission shaft, 7 is the working surface of the table cone grinding disc with grooves , D is the nominal diameter of the dynamic grinding cone, H is the nominal height of the dynamic grinding cone, and α is the angle between the working surface of the table cone grinding disc.

[0038] As shown in Figure 1, the nominal diameter D of the table cone bottom of the dynamic grinding rotor can be in the range of 200-550mm, the nominal height H of the table cone of the dynamic grinding rotor can be in the range of 100-500mm, and the cone surface clip of the dynami...

Embodiment 2

[0043] The structure diagram of the complete coarse and medium crushing machine is shown in Figure 6: Among them, 2 is the movable mill rotor in the table cone grinding disc, 3 is the water cooling cavity in the fixed mill, and 4 is the water cooling hole in the dynamic mill Cavity, 5 is the feeding thread with notch, 6 is the transmission shaft, 7 is the working surface of the table cone grinding disc with groove groove, 8 is the worm gear device for adjusting the gap of the working surface, 9 is the bearing seat, 10 is the discharge hole Cavity casing, 11 is the feeding cavity, 12 is the bearing seat, 13 is the limit mechanism, 14 is the coupling, 15 is the reducer, 16 is the transmission belt, 17 is the motor, 18 is the frame, 19 is the discharge road board.

[0044] In the pulverizer of the prior art, when the working surfaces of the moving grinding rotor and the static grinding stator are in contact with each other, the end of the main bearing is just in contact with the ...

Embodiment 3

[0048] The schematic diagram of Fig. 8 demonstrates a locking structure arranged on the worm wheel of the pulverizer, wherein: 24 is the worm gear box, 25 is the bearing cover, 26 is the worm, and 27 is the locking mechanism. The worm 26 adjusts the relative rotational speed between the dynamic grinding rotor and the static grinding stator by adjusting the gear of the worm gear case 24 . In the prior art, due to the high vibration intensity during the working process of the pulverizer, it is easy to make the adjustment position of the worm deviate. The present inventor has provided a locking mechanism 27 on the bearing through cover 25 of the worm gear case 24, and the locking mechanism 27 can position and lock the gears inside the worm gear case 24, so as to accurately control the relationship between the dynamic grinding rotor and the static grinding stator. The technical effect of the relative rotational speed between them. Of course, according to actual needs, other parts...

Abstract

The invention relates to an elastomer rough and medium grinder with a cone grinding disc. A shell of the cone grinding disc is provided with a limit mechanism for the axial movement limit of a main bearing of a conehead of a control table so as to guarantee that no zero clearance appears in the clearance of a working face of the cone grinding disc. The grinder is also characterized in that the relative rotate speeds of the dynamic grinding working shell face and the static grinding working shell face are in the range of 10 to 200 R / M, and the surface stiffness of a dynamic grinding working shell face and a static grinding working shell face is set at HIC 55-64 DEG C so as to ensure that the crusher has longer service life.

Description

technical field [0001] The present invention proposes a high-efficiency pulverizer for coarse and medium crushing of elastomers with a cone grinding disc, and specifically relates to the processing of high-molecular elastomers with steel wires or / and nylon fiber skeletons entrained in waste tires that have been broken into pieces. The unit crushing machine for further coarse and medium crushing belongs to the technical category of rubber elastic body crushing machinery. Background technique [0002] For the elastomer pulverizer with a cone grinding disc, the main purpose in the industry is fine pulverization. The specific usage is to pulverize the coarse elastomer powder of 5 to 40 mesh into mixed fine rubber powder with a particle size of 40 to 200 mesh, such as China Patent: CN2657779Y etc. all have more narrations to this; Also have the elastomer pulverizer of useful band platform cone grinding disc to be used as simultaneously to elastomer high-speed crushing and kneadin...
