Pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins. Equipment Design A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.
"Further, its unique rotor design allows the operator to change the cutter head size on the rotor instead being committed to just one size," Chocholko says. "One VIZ rotor can accommodate cutters as small as 1x1-inch for an output of one-fourth-inch particle size, and as large as 3x3 inches for bulky item size reduction such as bale ...
The Rittinger constant of 104.5 for the rotor impact mill grinding is larger than 58.6 for the hammer mill grinding (Fig. 5), indicating that the hammer mill used less energy than the rotor impact mill for similar size reduction. However, it should be noted that they were not operated in the similar grinding regime; the rotor impact mill had a ...

Size reduction techniques. The four basic techniques used in size reduction of dry powders are impact, shear, attrition and compression forces. In some cases, a combination of these may be found in a single mill type. Impact and attrition size-reduction methods include air classifying mills, pin mills, hammer mills and jet mills.
Two types of mills are commonly used in the pharmaceutical manufacturing process in order to reduce particle size: the hammer mill and the conical mill (Comil). Comils come in a variety of sizes, including tabletop laboratory devices to full-scale, high-capacity machines used for large pharmaceutical processing operations4. Compared with other ...
Excessive size reduction can lead to wasted electrical energy, unnecessary wear on mechanical equipment and possible digestive problems in livestock and poultry. ... Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 ...
Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations (i.e. powders inhaled directly into the lungs), suppositories and ointments require particles size to be below 60 mm size. To increase the therapeutic effectiveness of certain drugs by reducing the particle size. Size reduction produces particles in narrow size range.
GRANUMILL® size reduction systems meet FDA SUPAC (Scale-Up and Post-Approval Changes) guidelines for both impact and screening mills, allowing for low-RPM screening of agglomerates in addition to high-speed impact milling. The mill's versatile design combined with the new, removable containment option provides users with the flexibility to ...
The Mikro Pulverizer® Hammer & Screen Mill combines a high speed mechanical impact mill with an outlet screen to control particle size. These hammer and screen mills are used in the production environment to provide continuous size reduction at high capacities for a variety of materials. This type of mill is used widely for the…
Health & Medicine. Dec. 07, 2019. 24,068 views. Generally, size reduction and size separation are combined to obtain powder with the desired particle size distribution (PSD) for acceptable flow and compressibility for downstream processing . The mechanical process of reducing the particle size of a solid is also called milling. Pharmacy Universe.
The new cutting mill SM 200 is a powerful and easy-to-operate instrument for efficient primary and fine size reduction. Cleaning is made particularly easy. Within the group of the RETSCH cutting mills, it is the universal standard model which covers a vast range of applications with its strong 2.2 kW drive and 1,500 rpm rotor speed.
Size reduction is a proce ss of reducing large solid unit masses - vegetables o r chemical s ubstances into small uni t masses, coarse particles or fine particles. Size reduction is …
The rotor mill series includes Preliminary size reduction Sample dividers ultra centrifugal mills, rotor beater mills and cross beater mills. Depending on the partic-ular instrument they are suit-able for the preliminary and fine size reduction of soft, fibrous and also hard mate-rials. A final fineness of down to 40 µm can often be achieved

Particle Size Reduction : The solubility of a solid is intrinsically related to the particle size. Reduction of particle size of a solid can be achieved by various means such as rotor stator inline homogenizer, bead mill, etc. leading to an increase in surface area with enhanced dissolution.
In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction equipment, such as: colloid mills (e.g. ball mills, bead mills), disc mills, jet mills, rotor-stator mixers (ultra turrax) or high-pressure homogenizers.
