The RTP33 is an exceptionally powerful continuous automatic rotary pellet press designed for pharmaceutical, chemical or food technology manufacturers who need to produce pellets in industrial quantities. The 2.2kW, three phase motor of this pellet press drives 33 sets of dies, pressing granular or dry powdered raw materials into round pellets of up to 12mm in diameter. With a maximum pellet producing capacity of up to 118,000 units per hour, the RTP33 can be relied on to satisfy large scale commercial demand for high quality pellets of a standardised weight.

Despite its power and large productive potential, the RTP33 is an extremely economical choice that produces pellets at a low cost-per-unit. It is especially efficient in its use of raw materials, thanks to an integral powder suction unit that avoids wastage. The machine has been built from industrial grade components that will ensure a long working life, and it is very simple to operate, with minimal controls to learn. Thoughtful design also ensures that this pill press is easy to maintain.

Aimed squarely at large scale mass production, the RTP33 is one of the fastest pellet pressing machines in our range, and is a natural choice for commercial producers.

Main benefits of the RTP33 Pellet Press

  • 33 cutting heads giving mass production speed of up to 118,000 units per hour
  • Powerful, 2.2kW motor
  • Highly efficient - built-in powder suction unit recycles powder avoids wastage and keeps dies free from obstruction
  • Built-in hydraulic power pack
  • Mechanical buffer unit to prevent overload damage to punches
  • Simple to operate through electric control system
  • Easily adjusted turret speed
  • 12mm maximum pellet diameter
  • Easily adjusted pellet thickness up to maximum 6mm thick

  • Highly reliable with rugged, industrial quality construction
  • A solidly engineered pellet press for years of uncomplicated commercial use.


Suitable for pressing granular material or dry powders, the RTP33 rotary pellet press benefits from an impressive set of features. It is built on a double press format, with 33 cutting heads giving a manufacturing capacity of between 43,000 and 118,000 units per hour, depending on the type of raw materials being used. A reliable 2.2Kw motor generates large reserves of power that are managed via simple electronic controls. The motor is complemented by refinements such as the built-in hydraulic power pack, and a mechanical buffer unit to prevent overload damage to the pellet press’s punches.

Given that this is a machine intended for large scale manufacturing, and which processes a substantial quantity of raw materials, it is essential that it uses those raw materials efficiently. The RTP33 pellet press achieves this brilliantly, thanks to its built-in powder suction unit that prevents wastage by automatically recovering excess powder from the die area and recycling it. This also keeps the die heads clear of obstruction, and helps ensure smooth operation without delays.

All the relevant settings on this pellet press are easy to adjust, including turret speed, fill depth, diameter and pellet density. Up to 40kN of available pressure means that the RTP33 produces consistently solid pellets with a professional finish. A maximum fill depth of 15mm gives a maximum pellet depth of 6mm, making it suitable for a wide range of applications. The RTP33 produces round pellets up to 12mm in diameter, and the dies can impress designs or letters onto the pellet surface.

RTP33 Pellet Press in Use

The outstanding impression when using this pellet press is one of speed and efficiency. The 33 dies turn out pellets at an eye blurring rate, and the powerful motor sounds reassuringly calm.

The speed selector offers two choices, depending on the type of pellet you are pressing. Slow speed gives a pressing rate of between 43,000 and 79,000 pellets an hour, and is intended for difficult-to-press materials such as ceramics. High speed gives a pressing capacity of 59,000 to 118,000 pellets per hour, and is suitable for normal raw materials.

When it comes to changing the dies, despite the sheer number involved, the process itself is straightforward and easy to master.

Because this pellet press is intended for long runs that produce industrial quantities, it has two large hoppers for raw materials so that the operator does not spend their time constantly running backwards and forwards to fill the machine. Maintenance is also carefully thought through, with easy access to internal parts, which can then be lifted out for replacement or repair.

Technical Specifications

The RTP33 pellet press has measurements of 1100mm x 480mm x 680mm, and weighs 850 kg. Inside the crate the dimensions will be 1600mm x 950mm x 960mm. It produces a maximum pressure of 40kN and has a turret speed of 30 r/min. Its motor operates at a maximum power of 2.2kW. Available for either single phase or three-phase compatibility, the machine can be supplied either for 110v or 220v use.

The maximum fill depth is 15mm, and the maximum diameter for round pellets is 12mm. The machine produces pellets up to 6mm thick.

Our View

This is a remarkably efficient machine that gets on reliably with the job of churning out top quality pellets at a consistent rate. The RTP33 is very good value, considering the speed and build quality it offers. Weighing in at 850 kg it is a sturdy piece of equipment that has been built with solid practicality in mind rather than good looks, but that only adds to its appeal. If you are a chemical company, raw material, technology company or any manufacturer needing large scale production of round pellets at a low unit cost, this pellet press will meet your needs admirably.

Does this machine come with free training?

Yes, we offer free training at your local LFA office. For a list of our office addresses, see here. Training is normally completed in less than one day, but please get in touch for more information.

How quickly will the press pay for itself?

We've created a calculator on our website for most of our tablet presses. See the "profit calculator" tab on the product page and enter your profit per tablet to see how many running hours the press will pay for itself and how much profit per hour it will generate.

Can I come to one of your facility for training with my own formula?

Yes, you can but there are a number of requirements that we need to fulfil first.

You will need to contact our team and provided them with a copy of all of your MSDS for all of the components of your mix.

We need to have a good understanding of your business and the challenges you are facing.

You will also need to book an appointment with the office that you would like to visit.

Can I order custom tooling?

Yes. You can order custom tooling here

What particle size will work on this machine?

As with any tablet press, it is good to have a particle size of around 80-60 mesh.

This would be large enough to avoid large losses and small enough to flow well through the machine. If the powder is finer than this then you are going to experience a larger level of loss.

If the particles are larger than this then it might not flow through the machine well and get caught as it is trying to enter into the die bore.

This being said every powder is very different and you will need to do tries to work out what is best for them.

What technical support and training comes with this machine?

There are a number of ways we are able to support you:

  • Every machine comes with a full manual to be emailed to you after purchase.
  • There is a large range of video tutorials to teach you how to use the press.

Can you set this machine up for an X mg tablet weight?

Yes, the TDP range all have a weight adjustment for it.

It is the bottom of the two cogs on the lower drift pin assembly.

Here is a link to a video showing you how to tune up the TDP 5:

It is important to know that the exact weight of each tablet will vary from tablet to tablet.

A well-homogenized mix that has a consistent granule size should be able to achieve an accuracy of +/- 3% or less.

What should we do if we don't want to use any excipients, especially binders?

Get a capsule filler.

You will not be able to make tablets.
