Problems solved by technology

Due to the structural reasons of the currently used micro-grinding device, the efficiency is not high during micro-grinding, and more dust is likely to be generated, which pollutes the indoor air and affects the health of the operators.

Embodiment 1

[0040] see figure 1 The micro-grinding system shown, it comprises

[0041] Pre-crushing equipment 1, used for pre-crushing the agglomerated material to be crushed, so as to obtain granular material particles to be crushed;

[0042] Micro-grinding equipment 2, for further pulverizing the material particles to be pulverized discharged from the pre-grinding equipment;

[0043] A material collector 3, the feed port of the material collector is connected to the discharge pipe of the micro-grinding equipment through a pipeline, and the first collecting box 31 is arranged at the lower part of the material collector;

[0044] Dust collector 4, the upper part of the collector is connected to the inlet of the dust collector through a pipeline, and the second collection box 44 is arranged at the lower part of the dust collector;

[0045] The induced draft fan 5 is used to suck the particles of the material to be pulverized from the micro pulverization equipment to the collector and the...

Embodiment 2

[0054] Different from the embodiment, the dust collector 4 also includes a solenoid valve controlled by a pulse controller, and the induced draft fan is installed outside the air outlet of the dust collector, and the solenoid valve is connected to the filter bag exit. see Figure 6 shown.

[0055] During the crushing process, when the dust blocked on the outer wall of the filter bag continues to increase, the resistance of the dust collector will continue to increase. In order to ensure that the resistance of the dust collector is controlled within the specified range, the pulse controller sends out a control signal at a fixed interval to turn on the electromagnetic The valve makes the filter bag expand instantly and then shrink sharply, so that the excess dust particles accumulated on the outer wall of the filter bag are eliminated, and the falling dust enters the second collection box through the outlet of the ash hopper for collection, so that the filter bag can be obtaine...

Abstract

The invention relates to a fine grinding system and a grinding method thereof. The system is characterized by comprising pre-grinding equipment, fine grinding equipment, a material collector, a dust catcher and a draught fan, wherein the pre-grinding equipment is used for pre-grinding block materials to be grinded, so as to obtain granular grains of the materials to be grinded; the fine grinding equipment is used for further grinding the grains of the materials to be grinded, which are discharged from the pre-grinding equipment; a feeding opening of the material collector is connected with a discharging pipe of the fine grinding equipment through a pipeline and the lower part of the material collector is provided with a first material collection box; the upper part of the material collector is connected with an inlet of the dust catcher through the pipeline and the lower part of the dust catcher is provided with a second material collection box; and the draught fan is used for sequentially sucking the grains of the materials to be grinded into the material collector from the fine grinding equipment and then conveying the grains into the dust catcher. According to the fine grinding system and the grinding method thereof, provided by the invention, the materials are pre-grinded by the pre-grinding equipment and the grains are further grinded and separated by the fine grinding equipment; the grinded grains are collected by the material collector and then are de-dusted by the dust catcher; and therefore, the grinding efficiency is high and the recovery rate of dust is high.

Description

technical field [0001] The invention relates to a fine pulverization system and a pulverization method thereof. Background technique [0002] Industrial and agricultural processed products and waste products such as chemicals, medicines, fuels, pesticides, metallurgy, food, tobacco, feed, plastics, plant fibers, metals, etc. often need to use crushing technology, especially industrial and agricultural wastes can be recycled after crushing . The micro-grinding technology has obvious advantages over the traditional crushing technology. First, the crushing speed is fast, without overheating, and can even be carried out at low temperature. Second, the material to be crushed can be crushed into smaller particles for recycling. use. Due to the structural reasons of the currently used micro-grinding device, the micro-grinding is not efficient, and more dust is likely to be generated, which pollutes the indoor air and affects the health of operators. [0003] For various seals, b...
