DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The process flow of the double grinding rollers 9 is simple, and compared with the ball mill roller, it occupies a small area, has low unit power consumption, low metal wear, low machine noise, and high grinding efficiency.

[0017] Specifically, a plurality of legs 11 are provided on the side wall of the grinding box 1, and reinforcing rods 12 are provided between the plurality of legs 11. The provided legs 11 increase the height of the grinding box 1 to facilitate use by staff.

[0018] Specifically, a discharge pipe 13 is provided at the lower end of the grinding box 1 , and a control valve is provided on the discharge pipe 13 , and the opening and closing of the discharge pipe 13 is controlled by the control valve.

[0019] Specifically, a vibration motor 14 is provided at the lower end of the first guide plate 4 and the second guide plate 8. The vibration motor is a group of adjustable eccentric blocks installed at both ends of the rotor shaft. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the exciting force. The vibration motor has a large vibration frequency range. Only when the exciting force and power are properly matched can the mechanical noise be reduced.

[0020] Specifically, a coupling 15 is provided between the driving end of the first drive motor 7 and the crushing roller 6, and a coupling 15 is provided between the driving end of the second drive motor 10 and the grinding roller 9. A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the process of transmitting motion and power, and does not disengage under normal circumstances. It is also used as a safety device to prevent the connected parts from being subjected to excessive loads and plays a role in overload protection. A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. It is often composed of two halves, which are connected by keys or tight fits, fastened to the two shaft ends, and then the two halves are connected. The coupling can also compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, as well as mitigate impact and absorb vibration.

[0021] Working principle: When the utility model is working, the first guide plate 4 is set to divert the graphite raw material entering the grinding box 1, so that it enters the first crushing chamber 2 and the second crushing chamber 3 respectively, and the first drive motor 7 is started to drive the set crushing roller 6 to initially crush the graphite particles. The graphite particles crushed to a suitable size fall onto the second guide plate 8 through the filter screen. The second guide plate 8 guides the crushed graphite particles to the grinding roller 9. Starting the second drive motor 10 can make the grinding roller 9 work, thereby ensuring the uniformity of the grinding of the graphite particles by the grinding roller.
