Problems solved by technology

[0002] At present, the freezing and crushing devices on the market are more common to use the technology of combining freezing and crushing to make materials crushed in a low-temperature frozen state to make granular or powdery materials, but the existing equipment usually uses one-time crushing. For some material processing procedures with high particle size requirements, it is difficult to meet the requirements in one-time crushing.

Abstract

The invention relates to a freezing pulverizing machine. The freezing pulverizing machine comprises a grinding machine, a feeding port, a liquid nitrogen inlet, a classification wheel, a discharging pipe, a first motor and a second motor. The feeding port and the liquid nitrogen inlet communicate with the grinding machine through a charging pipe. The other end of the grinding machine is connected with one end of the classification wheel, and the other end of the classification wheel is connected with the discharging pipe. The first motor drives the grinding machine, the second motor drives the classification wheel, the grinding motor pulverizes frozen materials through a movable cutter set and shearing, tearing and pulling of a gear ring, and the classification wheel recycles part of coarse particles through a coarse powder backflow port to the grinding machine for secondary pulverizing. Through the freezing pulverizing machine, material pulverizing is conducted in the manner, and the product better meets the standard.

Description

technical field [0001] The invention relates to the field of freezing and crushing devices, in particular to a freezing and crushing machine. Background technique [0002] At present, the freezing and crushing devices on the market are more common to use the technology of combining freezing and crushing to make materials crushed in a low-temperature frozen state to make granular or powdery materials, but the existing equipment usually uses one-time crushing. For some material processing procedures with high particle size requirements, it is difficult to meet the requirements in one-time crushing. Especially when crushing some materials with strong heat sensitivity, general crushing devices, such as hammer mills, are used to crush the materials in the form of impact. Because a large amount of heat will be generated during the impact crushing process, it is easy to change the original composition of the materials. . Contents of the invention [0003] The purpose of the pre...
