Description

Technical Field

[0001] The utility model relates to the technical field of sodium metasilicate production equipment, in particular to a crusher for producing small-particle sodium metasilicate. Background Art

[0002] Sodium metasilicate is mainly used as an analytical reagent, a fabric fire retardant, an adhesive, a hardening agent, a weight-increasing agent, and a filler. It is easily soluble in water, soluble in dilute sodium hydroxide solution, insoluble in ethanol and acid, and is harmful to human skin. When producing, it needs to be crushed into small particles by a crusher.

[0003] However, after the current sodium metasilicate crushing equipment crushes it, it cannot automatically recycle and crush unqualified raw materials. It still needs to be manually re-screened and poured in again for crushing. Moreover, most crushing equipment performs single crushing treatment. Therefore, when sodium metasilicate is crushed into small particles, the crushing effect is not good, and it wastes working time for classification, recycling, and re-crushing, affecting work efficiency.

[0004] Therefore, a crusher for producing small-particle sodium metasilicate is proposed. Content of the Utility Model
