Description

Screening device for calcium carbonate processing Technical Field The utility model relates to the technical field of screening devices, in particular to a screening device for calcium carbonate processing. Background The calcium carbonate powder can be filled in rubber in a large amount, the product volume is increased, the use amount of natural rubber is reduced, the production cost of concrete can be reduced by the calcium carbonate powder in the building industry, the toughness and strength of the concrete can be increased, the calcium carbonate powder can play a framework role in plastic products in the plastic industry, the stability of the size of the plastic products is greatly improved, the hardness of the products is improved, the gloss and the flatness of the plastic products are improved, the use of the calcium carbonate powder with different particle sizes is also greatly different, and the grading screening of the calcium carbonate powder is necessary. For example, the application number is CN202121896414.9, the utility model belongs to the technical field of screening devices, and particularly relates to a grading screening device for calcium carbonate powder. This a hierarchical sieving mechanism for calcium carbonate powder, through setting up quick blocking-free sieving mechanism, start vibrations dominant force motor and positive and negative rotation dominant force motor, when positive and negative rotation dominant force motor forward, drive S type scraper blade forward rotation for the calcium carbonate powder that falls on the subdivision sieve is concentrated to the middle part rotationally, makes the less calcium carbonate powder of granule drop down, and discharges through the fine material export, when positive and negative rotation dominant force motor reverses, drives S type scraper blade reversal, makes the calcium carbonate powder that falls on the subdivision sieve pushed the outside rotationally, and discharges through the coarse material mouth. The calcium carbonate powder adhered to the subdivision sieve plate is vibrated down through the vibration main force motor, so that the technical problem of low screening efficiency of the existing screening device is effectively solved.
