Which of the following factors affects size reduction?

Size reduction is influenced by various factors. These include various physical properties like moisture content, hardness, stickiness, toughness, slipperiness, abrasiveness etc.

How do you reduce particle size?

Grinders use shear and impact to grind larger particles into smaller ones. Examples of grinders include roller mills (used in producing wheat flour), ball mills (widely used in producing cement, ceramics and pigments), and hammer mills (often used in waste management to break down large materials).

What is the most preferrable milling technique?

ACMsACMs are the most widely used milling technology in the powder-processing industry today for the general size reduction of fine chemicals and food products.

Which mill is used for low melting point drug?

Jet millsJet mills can grind materials with low melting points effectively because these mills have intrinsic cooling due to compressed air expansion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low melting points for coarse grinding applications.

Which is the disadvantage of the sieve shaker method?

Disadvantages. It is practically impossible to measure sprays or emulsions and cohesive and agglomerated materials such as clays. Standard sieves range from 38 μm to 4.75 mm (0.187 in.). The method is usually labor intensive.

What is edge runner?

1 : a stone or metal wheel in an edge mill. 2 : a machine consisting of one or more heavy steel rolls or grindstones set on a horizontal shaft rotating round a pan or trough that is used for crushing stone, fibrous matter for papermaking, or other material.

Which mill is preferred for wet grinding?

Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed.

What do you mean by size reduction?

Size reduction is a process of reducing large solid unit masses – vegetables or chemical substances into small unit masses, coarse particles or fine particles. … Size reduction process is also referred to as Comminution and Grinding.

How do you reduce particle size in powder?

Many particle size measurements are made to track size reduction operations such as milling, mixing, homogenizing, etc. The size reduction unit operation is performed under set conditions or for a required time frame until a specified size is achieved, as determined by the measurement.

Which is not size reduction process?

Explanation: Burning is NOT a method used for size reduction.

Why do we reduce size?

Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particles or fine particles. … The important reasons for size reduction are easy handling, increase in surface area per unit volume and separation of entrapped components.
