The present invention relates to a pulverizer, and more particularly, to a pulverizer capable of finely pulverizing raw materials such as grains and minerals of a small size to be input by a rotary centrifugal force.

Generally, the grinder is divided into a dry grinder and a wet grinder, and the dry grinder is configured to grind solid dry raw materials (grains, minerals, etc.), and the wet grinder is a wet raw material (food, vegetables, etc.). It is configured to be suitable for grinding.

The pulverizer composed of the raw materials to be pulverized as described above is mainly used to crush the raw materials to a desired size by using compression, impact, and rotation means. The pulverization method used here is a ball, a roller, Grinding is performed using a hammer or rotary method.

However, the pulverizers of the above-described method all have a problem that the raw materials can be pulverized by rotating, pressing or impacting, and thus, when the ultrafine particles are required, the raw materials cannot be crushed into the ultrafine particles.

Of course, it is not impossible to grind the ultra-fine particles of the desired size with the grinders at all, but the grinding time becomes considerably longer when grinding into ultra-fine particles, and in some cases it is limited to grinding the ultra-fine particles of the desired size, There is a cumbersome problem of having to grind after replacing with a separate grind means.

In addition, the pulverizer has a hassle that a series of grinding process that can not be added again before the input raw material is pulverized into the desired degree of ultrafine particles and discharged the crushed ultrafine particles are not continuously performed.

Therefore, an object of the present invention is to double-pulverize the raw material to be crushed with different rotary centrifugal force to be able to pulverize to the desired degree of ultra-fine particles.

The grinding means 300 has a cylindrical lower housing 302 having a predetermined diameter and height and is provided with an air suction opening 301; An upper housing 304 having an upper portion of the lower housing 302 having a partition 303 for separating the input raw material and the crushed raw material; First rotating shaft 307 having upper and lower bearing parts 306 inside the upper and lower housings 302 and 304 inserted into the outer bearing part 305 provided on the case 100. )and; A grinding disc 308 for grinding the input raw material while rotating at an upper end of the first pivot 307; First grinding means (310) configured at a lower end of the first pivotal shaft (307), the first pulley (309) for transmitting a predetermined rotational power arbitrarily set; It is inserted into the upper and lower bearing portion 306 provided in the first rotation shaft 307 of the first grinding means 310 is coupled to the sealing member 321, nut 322, washer 323 to rotate A second pivot 324; A separation wheel 326 having radially inclined wings 325 causing vortices at an upper end of the second pivot 324; Leaving prevention cap 327 to prevent the separation of the separation 326 and; The second grinding means 320 is provided with a second pulley 328 for transmitting a predetermined rotational force to the lower end of the second rotating shaft 324.

The power supply means 400 includes a first motor 410 for supplying a predetermined rotational power to the belt 401 arbitrarily predetermined to the first pulley 309 of the first grinding means 310; Each of the second motors 420 is configured to supply a predetermined rotational power to the belt 421 to the second grinding means 320.

In the figure, reference numeral 350 is a door that opens and closes the upper portion of the upper lower jaw 302 which is a grinding means.

The present invention configured as described above is crushed through the hopper 201 mounted on the input passage 202 of the raw material input means 200 in the upper housing 302 of the crushing means 300 coupled to the upper portion of the case 100 When the raw material to be introduced is input, the raw material introduced into the input passage 202 is rotated by the screw 204 by the rotation of the motor 203 located at the rear, and the raw material introduced into the input passage 202 is crushed by the grinding means ( Into the first grinding means 310 of the 300, the raw material introduced into the first grinding means 310 is located on the upper surface of the grinding disc 308.

The raw material located on the upper surface of the grinding disc 308 is fixed to the first rotation shaft 307 through the first belt 401 the rotational driving force generated from the first motor 410 which is the power supply means 400. The first pulley 309 is transmitted to the first pulley 309 to rotate, and the first pivot shaft 307 is supported by the outer bearing part 305 by the rotation of the first pulley 309. The grinding disc 308 is rotated (800 rpm).
