Other Tablet Compression Machine Parts 1. Tablet Compression Machine Hopper The tablet compression process starts from here. Tablet press hoppers come in a wide range of shapes and designs. Whatever the shape, it should be such that the material can flow seamlessly into the tablet compression chamber.

Again, since it is one section that is in direct contact with the material, it is made of stainless steel. Arrow shows exact location of tablet press hopper Depending on the design of a tablet press machine, you can fill the powder manually or using other automated systems.

As tablet press machine manufacturer, we put every measure in place to ensure there is a consistent flow of powder from the hopper to compression systems. Here are major concerns that we have addressed so far: Hoppers may feature optimal flow angles to facilitate flow, especially where it is nearly impossible to adjust formulation.

Some hoppers may feature vibratory rods. This is done carefully to enhance product flow and to prevent possible product separation. At any given point, the design of these tablet compression machine parts aims to eliminate possible feeder starvation. Feeder System This yet another critical part of the tablet compression process.

Remember, at any given time, the design of the system should be such that it allows an accurate and consistent amount of powder to flow to the punch and die system. This shows a section of feeding system. Tablet press machine feeder system is made up two critical components: Feeder housing Material from the hopper will enter the dye system through the housing. The feeding process should be consistent and accurate to produce high quality tablets. The feeding housing is made of stainless steel L since it is in contact with the product.

Also, the product must not stick on the feeder housing as it will cause inconsistencies during the feeding process. Feed peddles Quite a number of high speed rotary tablet press machines have a feed peddles.

The feed peddles ensures consistent and accurate material feeding into the die systems. Without a feed peddle, especially if the machine is operating at a high speed, there could be chances of some dies being filled half way. This may result in tablets with varying thickness or the degree of compaction.

Tablet Press Punches This is yet another critical part of the tablet compression machine parts. Normally, you can choose from simple to complex shapes of tablet press punches. The design and shape of a press punch tool design have a direct impact on the tablet quality. A reason why here at SaintyCo, we design tablet presses with great accuracy and precision. Under normal circumstances, these tablet compression parts are subjected to abrasive environments and exposed to extremely high pressure.

Therefore, they require high quality material and if possible with a special coating to prevent sticking or wear. This animation shows the action of upper and lower punches. To produce the desired tablets, punches move within the die, thereby compressing powder into the desired tablets. In any tablet press machine, we have: Upper punch system Like the name suggests, the tablet press upper punches are on the upper section of the rotary system.

They move vertically, in and out of the die bore as you can see in the animation above. Lower punch system The lower punches are on the lower section of the rotary system of the tablet press machine. During the tablet compression process, the lower punches remain within the die bore throughout the entire cycle. Tablet Press Die System Normally, whenever we talk about the tablet press punch then the next component that comes in mind is the die system.

As I had mentioned earlier, the movement of tablet press machine punches, takes place within the die bore or cavity. Therefore, the punch and die must be machined together to ensure compatibility. It is in the die cavity that the powder is compressed into desired tablets of definite thickness and size. Here are different shapes and sizes of dies in tablet press machine.

It is the die cavity that determines both the thickness and size of a tablet. Like the punches, a die system should have the following key features: Clean impression on every punch Prevent chipping or damaging of tablets Feature anti-corrosion protection Have non-stick treatment Other critical features we consider whenever we are machining a tablet press die system include: Tapering angle; this is a critical aspect since it allows excess air to escape, while minimizing the tablet ejection force and frictional heat.

Other technical specifications include die height, chamfer, die bore and die diameter. Again, we cannot wrap up this section without talking about a fundamental component of the tablet press tooling system — turret. Tablet Press Turret There have been a lot of developments in the recent past as far as designing these tablet compression machine parts is concerned. As a matter of fact, turrets are the heart of tablet press tooling. The rotating turrets have holes that host the die system of a tablet making machine.

They are precisely machined to the required rotational tolerances and dimensions. Every bore on its surface ensures the die and punch are fully aligned for optimal tablet making process. Again, to guarantee efficiency and reliability, there is always need to allow for any necessary adjustments as far as the dynamisms in tablet compression processes are concerned. Therefore, it is for this reason that tablet press manufacturers are shifting from traditional turrets that were basically dies and punches, to segmented turrets that have segmented sections and punches.

This is a section of tablet press turret. A segmented rotary turret design increases production, while minimizing possible downtime during the manufacturing process. Furthermore, this new design allows for increased number of tablet compression stations and fast part changeover. Remember, it is the tablet press machine turret that determines the number of stations.

This helps to determine the production capacity of the machine for every complete rotation of the turret. Again, with a properly designed tablet tooling system, you can easily incorporate the multi-tip punches. This is common in the high capacity tablet press machines. Still, you can also opt for custom tablet press tooling systems. Tablet Press Machine Cam Tracks Cam tracks are other critical tablet compression machine parts that play an integral role in ensuring seamless tableting process.

The main work of the cam tracks is to guide the upper and lower punches in different stages in the tablet compression process. Cams, turret and impeller for the feeding system of tablet press machine That is, as the turret rotates, it is the cam trucks that move the punches in an up and down motion. This helps to control filling, compression and ejection of already processed tablets. For example, as the upper cam withdraws top punches from the die, powder flows in filling the cavity.

On the other hand, the lower cam track pushes the bottom punches upwards within the die cavity. This makes the die to be overfilled by material, allowing for accurate adjustment of the die content. Again, to achieve a maximum compression force, the upper cam track drives the top punch and the lower cam adjusts the bottom punch.

With the tablet compressed to the desired specifications, the upper cam withdraws top punches. On the other hand, the lower punches move upwards to expel the compressed tablets with the help of lower cam. In short, you can see that upper and lower cam tracks play an integral role at every tablet compression stage in these machines. It is a simple process that must be precisely controlled to achieve the desired tablet size and weight.

In most cases, tablet press machine manufacturers use servo motors to control movement of the cam track for accurate dosing. This is due to their high precision and ease of integration to other computerized systems of other machine parts. This process illustrates the filling process, compressing to tablet discharge. A critical procedure in this section of tablet compression process in the: Weight control By controlling the depth fill, tableting machine can easily regulate the content within its die cavity.

Normally, with the help of lower cam track, the bottom punch moves upwards to a predetermined height. This ensures the die cavity is filled to a required depth before any compression process begins. At times, as the bottom punch moves up, the excess powder may overflow. Therefore, to avoid wastages, the excess powder automatically moves to the next die cavity, which is just about to be filled. To achieve these, all the other components must coordinate smoothly for a seamless tableting process.

Compression Rollers The idea here, is to ensure only powder is compressed to the desired shape and size. However, at times you may find air within the powder particles. To achieve this, tablet compression machines feature a series of rollers that exert a sufficient amount of force to compress the powder.

That is, they expel air first before the compression process begins. A section of the tablet compression system. Most machines have two sets of rollers: Pre-compression rollers These are the very first rollers in rotary tablet press. Basically, these rollers apply a small amount of force on the upper and lower punches.

This gives the initial compression force. The aim of this process is to remove air that could be in the die or powder particles. Any air within the die cavity or powder particles will obviously result in low quality tables. Main compression rollers Main compression rollers exert a predetermined amount of force final compression force for the formation of tablets.

The compression force at this stage is higher than the pre-compression force. It is important that the rollers remain stable with no vibration during the entire process.

Tablet Press Ejection Cam Again, the ejection cam is located just after the main compression rollers. Like the other cam tracks, ejection cams are also critical aspects of tablet compression machine parts. Remember, after compression, the tablet is always fixed within the die systems space between lower and upper punches.

The ejection cams steadily and slowly push the bottom punch upwards. At the same time, the top cams move up and so are the top punches. As a result, the fully compressed tablets leave the die cavity, i. Take —off blade and Discharge Chute The take —off blades are fitted just above the feeder housing.
