Description

Technical Field

[0001] The present application relates to the technical field of heavy calcium powder processing equipment, and in particular to a crushing device for heavy calcium powder processing. Background Art

[0002] Heavy calcium carbonate, also known as heavy calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler with advantages such as high chemical purity, high inertness, resistance to chemical reactions, good thermal stability, resistance to decomposition, high whiteness, low oil absorption, low refractive index, softness, dryness, absence of crystal water, low hardness and abrasiveness, and is non-toxic, tasteless, odorless, and highly dispersible.

[0003] The production process for ground calcium carbonate is divided into two types: wet and dry. The dry process first uses a crusher to coarsely crush the limestone, which is then pulverized in a grinder to produce fine limestone powder. The grinders used in the dry process are often geared disc grinders. These grinders utilize high-speed relative motion between movable and fixed gear discs to pulverize the material through a combination of tooth impact, friction, and mutual impact. The material is then screened and discharged.

[0004] However, during the grinding process of heavy calcium carbonate using a toothed disc grinder, the screen is in a stationary state and the particle size of the heavy calcium carbonate powder is small, so the screen is prone to clogging. Since the outer side of the screen of the toothed disc grinder is a closed shell, when clearing the blockage, the screen can only be cleaned from the inside. The screen surrounds the circumference of the movable toothed disc. During the clearing operation, due to the obstruction and interference of the movable toothed disc, the clearing operation is relatively inconvenient, thereby increasing the labor intensity of the staff and reducing the clearing efficiency.
