Particle Size Reduction Techniques of Pharmaceutical
In pharmaceutical research and development, various new chemical entities (NCE) are found to be poorly water-soluble. Therefore, solubility enhancement, a key factor for higher bioavailability, is a major challenge in pharmaceutical industries. Particle size reduction is one such method that increases the surface area of the pharmaceutical The process Comminution involves size reduction and size-wise classification called as screening/ separation.

Comminution an overview ScienceDirect Topics
Comminution (break-down) techniques. Comminution is the reduction of solid material particle size by fracture via grinding, milling, or similar processes. Comminution techniques are usually employed to produce particulate nanomaterials (e.g., powder) from larger-sized or bulk materials.43.1 Introduction. Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, i.e. compression, impact and shear.DE-11: Lesson 43.

Size Reduction SpringerLink
Abstract. Size reduction refers to the process of the formation of small particles with a large surface area. The stress-strain curve of the material determines the energy needed for size reduction with a desirable particle size distribution. The study of equipment used for size reduction and their process parameters helps to reduce the Size reduction by mechanical actions, often called shredding or grinding, has been reported 14,15,16,17,18,19,20 and many types of equipment are commercially available for processing textile and carpet waste. 21, 22 In a typical process, the feedstock is cut by a rotary drum fitted with hardened blades against a feeding bed, and the cutSize Reduction an overview ScienceDirect Topics

CPE: Lesson 16. Size Reduction Equipments e-Krishi Shiksha
16.1 Size Reduction Equipments. There is a very wide range of size reduction equipment available and the following passages describe briefly the essential details of only a few of the most important types. (a) Hammer Mill: A standard hammer mill is shown in (Fig. 15.1a) and consists of a series of hinged or fixed hammers attached to a shaftproduct size of 10 x 10 (-4) m at the rate of 20 tonnes per hour. At this rate, the crusher consumes 40 kW of power of which 5 kW are required for running the mill empty. Calculate the power consumption if 12 tonnes/h of this product is further crushed to 5 x 10 (-4) m size in the same mill?

Equipments For Size Reduction And Diagram
Size-Reduction The principal types of size-reduction machines are as follows: Equipments B. Grinders (intermediate and fine) 1. Hammer mills, Impactors 2. Attrition mills 3. Tumbling. The product from an intermediate grinder might pass a 40-mesh screen and product from fine grinders pass a 200-mesh screen with a 74 m opening. Size-Reduction30.1 Introduction. Size reduction is the term related to the process in which the size of solids are reduced or broken into smaller items. It involves creation of smaller mass units from bigger mass units of the same material. To change this, the bigger mass units need to be subjected by the application of an external energy.Size Reduction-1: Grinding Unit Operations in Food
