Quicklime Slurry Residue Tester Slurry Yield Unslaked Residue 2.5L

Product Features & Attributes
This quicklime slurry residue tester is used to measure the slurry yield and unslaked residue content of quicklime, making it key equipment for evaluating quicklime quality. Suitable for lime quality testing in building materials, metallurgy, environmental protection, chemical and other industries.

Test Principle: A measured mass of quicklime sample is slaked in a measured volume of water. The unslaked residue is separated by sieving, dried and weighed to calculate the unslaked residue percentage. The slurry height after slaking is measured to calculate the slurry yield.

Structure:

• Sieve cylinder: Holds sample and water for slaking

• Outer cylinder: Collects slurry from sieve cylinder

• Cover: Prevents water evaporation during slaking

• Wooden rod: For stirring sample to promote slaking

• Round hole sieve: 5mm for residue sieving

• Enamel tray/evaporating dish: For drying residue

• Steel ruler: For measuring slurry height

Technical Features:

• Simple structure with easy operation

• Two-stage slaking process (20min+40min) for complete slaking

• Constant temperature drying (100~105℃) for accurate weighing

• Evaluates both slurry yield and unslaked residue content

• Results to two decimal places for accuracy

Test Procedure:

1. Weigh 1kg quicklime sample into sieve cylinder with 2500ml water (20±5℃)

2. Cover, stand for 20min, stir 2min with wooden rod

3. Stand for 40min, stir 2min again

4. Lift sieve cylinder, rinse residue with water until clear (total water ≤3000ml)

5. Transfer filtrate to enamel tray, dry at 100~105℃ to constant weight

6. Sieve with 5mm round hole sieve, weigh residue to calculate unslaked content

7. After 24h standing, measure slurry height to calculate slurry yield

Available in different specifications: different sieve cylinder volumes, different sieve mesh sizes, and different processing capacities to suit various lime samples and testing standards.

Mainly used in lime manufacturers, building material testing institutions, metallurgy quality inspection departments, environmental monitoring units, research universities, and more for quicklime slurry yield and unslaked residue content testing.
