Triple roller mill Construction and working principle: It is fitted with three rollers, made up of hard abrasion-resistant materials. Rollers are fitted in such a way that they come in close contact with each other and rotate at different speeds. A scraper is used to remove the final ointment of smooth and uniform texture.

A roller compactor generally consists of three major units. 1.A feeding system, which converts the powder to the compaction area between the rolls. 2.A compaction unit, where powder is compacted ...

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

Versatility: The WP120 is one of the most versatile roller compactors on the market. The WP120 can be utilized as a lab scale compaction trial machine using the Micro Batch set up for even the smallest material amounts. With the Mini Batch 25mm roll set up small lab or production runs can be achieved. With the standard 40mm wide rolls the WP120 ...

TYPES OF PIN MILLS Vertical Pin Mill Configuration Horizontal Pin Mill Configuration SPECIFICATIONS When one disc rotates, the size of the ground particles is 50-5 micro meter . If both the discs counter rotate, the particle size may be reduced to 2 micro meter. Pin mills may grind 0.05-6 tons/hr. Depending on the product end size of ...

Fluidized Bed Dryer Principle. The Fluidized bed dryer (FBD) works on a principle of fluidization of the feed materials. In this process, hot air is introduced at high pressure through a perforated bed of damp solid particulate. However, the solid particles are blown-up and remain suspended in the air channel, If air is allowed to flow through ...
