Chemistry Dictionary: slurry

A paste consisting of a suspension of a solid in a liquid.

Food Lover's Companion: slurry

A thin paste of water and flour, which is stirred into hot preparations (such as soups, stews and sauces) as a thickener. After the slurry is added, the mixture should be stirred and cooked for several minutes in order for the flour to lose its raw taste.

1. A mixture of water and any finely divided insoluble material such as clay or portland cement and water.
2. See mud.

Veterinary Dictionary: slurry

Top

Solids in suspension. Used as a method of feeding pigs—slurry is pumped through fixed lines and delivered to troughs by hoses equipped with gasoline pump fittings. Used also as a means of disposing of feces and urine from cesspits under animal accommodation or trap tanks attached to milking sheds. Disposal is usually onto pasture. This creates poisoning hazards with respect to heavy metals and transmission of disease such as salmonellosis or Johne's disease.

A slurry composed of glass beads in silicone oil flowing down an inclined plane.

A slurry is, in general, a thick suspension of solids in a liquid.

Examples of slurries

Examples of slurries include:

A mixture of water and cement to form concrete
A mixture of water, gelling agent, and oxidizers used as an explosive
A mixture of water and Bentonite used to make slurry walls
A mixture of wood pulp and water used to make paper
A mixture of water and animal waste used as fertilizer
Meat slurry, a food product
An abrasive substance used in chemical-mechanical polishing, a semiconductor manufacturing process
A mixture of ice crystals, water and freezing point depressant, called slurry ice
A wet-process cement rawmix
A mixture of water, ceramic powder and various additives (e.g., dispersant) used in the processing of ceramics.
A mixture of water and a starch (normally corn starch) used to thicken liquids to make a culinary sauce; usually for a clear sauce, as the product will be translucent. It is comparable to and often the same as a gravy.

Slurry calculations

Determining solids fraction

To determine the percent solids (or solids fraction) of a slurry from the density of the slurry, solids and liquid^[1]

$\phi_{sl}=\frac{\rho_{s}(\rho_{sl} - \rho_{l})}{\rho_{sl}(\rho_{s} - \rho_{l})}$

where

φ s l

is the solids fraction of the slurry

ρ s o l i d s

is the solids density

ρ s l u r r y

is the slurry density

ρ l i q u i d

is the liquid density

In aqueous slurries, as is common in mineral processing, the specific gravity of the species is typically used, and since $S G w a t e r$ is taken to be 1, this relation is typically written:

$\phi_{sl}=\frac{\rho_{s}(\rho_{sl} - 1)}{\rho_{sl}(\rho_{s} - 1)}$

even though specific gravity with units tons/m^3 is used instead of the SI density unit, kg/m^3.

Liquid mass from mass fraction of solids

To determine the mass of liquid in a sample given the mass of solids and the mass fraction: By definition

$\phi_{sl}=\frac{M_{s}}{M_{sl}}$

therefore

$M_{sl}=\frac{M_{s}}{\phi_{sl}}$

and

$M_{s}+M_{l}=\frac{M_{s}}{\phi_{sl}}$

then

$M_{l}=\frac{M_{s}}{\phi_{sl}}-M_{s}$

and therefore

$M_{l}=\frac{1-\phi_{sl}}{\phi_{sl}}M_{s}$

where

φ s l

is the solids fraction of the slurry

M s

is the mass or mass flow of solids in the sample or stream

M s l

is the mass or mass flow of slurry in the sample or stream

M l

is the mass or mass flow of liquid in the sample or stream
