About pressing of tablets

Find a consultant who will help you.
In the opinion of my clients, there are a lot of traders of pharmaceutical equipment in Russia, but units from them are aware of the processes, design features and capabilities of various models tablet equipment. You can buy a tablet press, and then run down a lot of problems that your supplier can not to solve. So my first advice is do not look for a tablet press, but look for an intelligent professional with experience in manufacture of tablets on different models of tablet presses.

Study the resources devoted to production of tablets.
Practice is very important, but do not forget about the theory. Explore our and similar sites devoted to production of tablets, tablet presses and the additional pharmaceutical equipment. At the first stage you having received the theoretical knowledge will be able to talk with experts in the same language. Study of tablet compression technology will give you primary knowledge that you subsequently will polish communicating with professionals. The most important point -is correct terminology. It is necessary to call things by their names.

Learn the features of your raw material (powder).
Often we meet a situation when customers are primarily engaged in choice of press, but do not have the slightest idea about what powders (their features and specifications) they want to compress. There are good loose powders, and there are similar to dust. Based on of these simple data selection of tablet press model can be different. Powders with good flowability can be pressed into budget models, but the powders with minimal flowability wich able to hang inside hoppers, have to be supplied by a special feeder. If you discovered that your powder has a problem, it is necessary to examine how the additional equipment can give the desired properties (for example, mixing it with more fluid additives or granulation).

Identify your needs in tablets.
Need to understand what the diameter and shape of pills you want to obtain. Same important is the performance measure. Remember that in tablet equipment is no such concept as weight. There are only thousands tablets per hour. Perfect to inform the supplier what the force should develop press in tons per cm2. Minimum - 1 ton, maximum - 28 tons. Models with low productivity per hour, and the minimum force is generally cheaper, and increasing of productivity and compression force automatically increases the price. Usually standard tablet press makes tablets having diameter to 12-13 mm. There are majority of such presses. Tablets with diameter from 15 mm or more are produced on models which a total a dozen pieces.

It is also important to know the the thickness of the future tablet.
Classical models of tablet presses have matrices height 22-25 mm, i.e. you can fill the powder depth up to 25 mm, when squeezed, depending on the properties of the tablet, its thickness may be 8 mm or less. If you are planning to obtain tablet of 20 mm height, the depth of the matrix must be at least 40 mm. Pay attention at the characteristics on the maximum height of tablets. In this case just necessary to consult with a specialist. Height of ready tablets can be adjusted from the minimum to the maximum possible within the capabilities of a tablet press.

Capacity of tablet press and quality of tablets.
Tablet strength as possibility to compress any powder into a strong tablet is achievable only two ways. The first way - in advance choose a model with great compression force, thereby compensate for deficiencies of powder. The second way - to prepare the available powder for pressing, having entered into it improving additives. Usually customers use the second option. Any powder can be compressed into tablets, the point is the effort of press and the possibility of completion the tablet mass. The first option - expense of money, the second option - the time spent on technology.

There are no resource except the website www.Tabletpress.ru, which have been collected such detailed info on the production of tablets.
