Pin Mill

The pin mill also categorized as a disc mill is a kind of milling equipment and the Pin Mill is suitable to grind crystal and brittle materials. The output fineness can be changed by replacement of the filtering-screen and adjustment of the rotor speed. With a wild range of applications to a variety of products, and the features of optional grind disc replacement for proper materials. Especially, this machine is easy to clean (water rinse) and do maintenance.

Pin Mill Introduction

Pin mill uses a series of pin breakers attached to discs instead of hammer in the rotating grinding head to achieve high energy impact between the mill and the particles.  It is traditionally employed to disintegrate starch- protein bond that exist in the material and produce fine flour. Pin mill work by similar principle as hammer mills (impacts and shearing) but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins. The mill product leaves by centrifugal forces to the periphery and is then collected or further processed.  This method of milling is most likely to produce materials in the micronized regime (as less than 100 mesh) and with uniform product size.

Ideal for pulverizing any materials (except highly oily or sticky ones). Due to the variety and interchangeability of internal components, this equipment has wide production adaptability, ranging from granular material to super-fine particles. Turnkey system is designed to prevent contamination of materials, increase efficiency, lower manpower requirements and maintain material quality

Hammer Mill Principles

This pulverizer machine uses the relative motion between movable and fixed teeth disc, the raw materials to be crushed undertakes the comprehensive actions such as impacted by teeth, friction, impacted between raw materials, finally the raw materials are crushed and pass the sieve. Its features are simple and solid in structure, stable in operation, high crushed efficiency. The crushed raw material can be discharged through the grinding chamber. Moreover, different size of raw material to be crushed can be got through screen with different mesh. Moreover 30B Dust Collecting Crushing Set is made from stainless steel. It makes the products of medicines, foodstuff and chemicals and so on are in conformity with the requirements of standard and meet the requirements of GMP.

1. By means of relative motion between movable and fixed fluted discs, material is crushed by impact and friction of the teeth and impact among the materials. The crushed material enters into the catcher automatically under the effect of rotating centrifugal force.

2. Crushed material by the centrifugal force, automatically enter the trap bag, the dust is filtered and recovered by dust collector through a cloth bag.

3. The crushing machine adopts high-quality AISI304 or AISI316L stainless steel, the production process no dust, and can improve the utilization of materials, reduce business costs. Replacement of different particle size is determined by the number of screens.

4. Inside the enclosure (crushing groove) all alveolar by precision machined so as to achieve a smooth surface, easy to clean and change the ordinary mill rough wall, easy to accumulate dust.

5. The powder grinding machine structure is simple, robust, smooth operation, the crushed material quickly and evenly, with good results.

Milling Machine Advantages

Hywell machinery B series pharmaceutical mills had the following advantages over conventional solutions.

1. Different types of knife make sure it suits for different materials.

2. Easily to replace the screen, simple operation and convenience washing.

3. Machine have light weight and moving flexible

4. the Pin Mill Machine have high efficiency and low energy, low noise

5. The end material can come out from the main grinding cavity directly, it can get different particle size by changing the different screen mesh .

6. Whole closed operation ensures a clean workshop, different type of dust-collector make the different dust collecting.

7. Water cooling device of axis to make sure the continuous operation for break the axis and working chamber because the high temperature of axis.

8. Special design such as the safety switch is accepted and also safety and credibility performance.

9. Highly polished inner and outer surfaces of the machine, no dead comer, easy to discharge materials, easy to clear. Confining to the requirement of GMP.

10. The B Series Pin grinding machine also connect with screw feeder or belt conveyor or vacuum feeder to send materials into pin mill .

11. The B Series Pin Mill also connect with ZS Round Vibration Sieve to separate again to get uniform materials.


B Series High Effect Grinding Machine has wide application and is wide used for pharmaceutical industry, chemical industry, pesticide industry foodstuff industry, grain industry, grain industry and so on.
