What is the Bulk Weight of Inert Ceramic Balls?
The bulk weight (bulk density) of inert ceramic balls mainly depends on their material (alumina content). The bulk weight range of different materials is as follows. The data refers to chemical industry standards and actual product parameters, which is for reference only and not suitable as an acceptance basis:
-
Ordinary Ceramic Balls (alumina content 30%-45%, including feldspathic, etc.): 1300-1400 kg/m³ (1.3-1.4 tons/m³);
-
Medium-Alumina Ceramic Balls (alumina content 60%-75%, including mullite, etc.): 1500-1600 kg/m³ (1.5-1.6 tons/m³);
-
High-Alumina Ceramic Balls (alumina content 70%-90%, including mullite-corundum, etc.): 1600-1800 kg/m³ (1.6-1.8 tons/m³);
-
Corundum Ceramic Balls (alumina content ≥90%): ≥1800 kg/m³ (≥1.8 tons/m³), some can reach 1.9-2.1 tons/m³.
Supplementary Note: The bulk weight will be affected by factors such as the packing density of ceramic balls and particle size grading. The actual value shall be subject to the specific product specification sheet.
Inert Ceramic Ball Bulk Weight FAQ
Q1: Are the bulk weight and bulk density of inert ceramic balls the same concept?
A1: Yes, they are the same concept. Both refer to the weight of inert ceramic balls per unit volume after stacking (usually expressed in kg/m³ or tons/m³), but they are called differently.
Q2: What factors are related to the bulk weight of inert ceramic balls?
A2: It is mainly related to 3 factors: ① Material (the higher the alumina content, the greater the bulk weight); ② Packing density; ③ Particle size and grading of ceramic balls.
Q3: What impact does the bulk weight of inert ceramic balls have on their use?
A3: It has two impacts: ① Affects the pressure drop of the reactor bed (the heavier and denser the stacking, the greater the pressure drop); ② Affects equipment load-bearing (a higher bulk weight requires higher requirements for the bottom support of the reactor).
