The ERWEKA All-Purpose system is based on a powerful drive unit available in two versions. The various attachments can be easily and quickly connected by means of a coupling. The drive unit AR 403 is equipped with a three-phase AC motor. The sturdy ball bearing worm gear drive is completely maintenance free and provides an output torque of max. 23 Nm. The unit features electronic speed control, variable between 20 and 400 rpm. A digital dial regulates the speed.
Through permanent nominal/actual adjustment the preselected speed is kept, even under varying load. The AR 403-S is similar to the AR 403 but has a different drive train. This connection is designed for heavy use.
Available options:
ERWEKA’s All-Purpose equipment is the ideal solution for small scale production in the pharmaceutical, chemical, cosmetic and food industries.

The Ball Mill KM is used for grinding crystalline materials and for mixing dry, or under certain circumstances, moist materials. The drum is available with 0, 5 and 10 litre volume. The balls are available with a diameter from 30 to 50 mm. The drum is sealed airtight with a lid and is delivered including a frame for the drive unit. The drum and balls can be sterilized in water. For using the ball mill, a drive support is needed, which is optionally available in a lengthened version for the simultaneous use of two mills of the same size.
The ERWEKA coating pan is used for the development of coating tablets. The universal gear (UG) is required to attach the coating pan to the motor drive. This allows for adjusting the angle of the pan, thus getting an optimum result from the coating process.
Versions:
The CM is designed for homogenization of dry products to a specified particle size, reduction of oversized particles to the desired size and milling of agglomerates back to the initial size. A set of shims to adjust the clearance between the rotor and screen (0.5 mm to 3.0 mm) is supplied. It allows a flow rate of up to max 40 kg / h with a rotor speed of 0 - 1200 rpm. A safety interlock helps to prevent injuries.
The Double Cone Mixer allows mixing of free-flowing powders and granules. The arrangement of the mixer in combination with the angle adjustment of the universal gear UG allows a multi-dimensional mixing process. The mixing vessel (11,9 liter volume, working capacity 50 %) is made of stainless steel.
The two-station dosing and filling unit is suitable for the drop-free filling of all types of different liquids. The dispense volume is easily adjustable. Quick removal of the pumps and valves for cleaning and sterilisation. The receiving container holder can be easily adjusted to accommodate various sizes. All parts coming into contact with the product are made of stainless steel.
The ERWEKA FDF comes without pumps. Optional dosing pumps for filling volume 5 to 30 ml (DP 30) and 20 to 150 ml (DP 150) are available. It comes with one set of filing nozzles (6 mm and 8 mm o.d.). Filling nozzles with different diameters are available per request. The FDF can be operated with a foot switch.
Specifications
Dosing Machine FDS is suitable for filling precise quantities of ointments, lotions, emulsions and similar products into tubes, cans, bottles etc. The standard unit has a dosing range of 10-200 ml. Quick removal of the pump and hopper (19 liter volume) for cleaning. Filling nozzles of 2, 4 and 8 mm are part of the standard package.
An additional cylinder unit to accommodate the filling range from 0.5 to 25 ml together with dispense heads with different apertures and special heads for filling tubes are available on request. The FDS can be operated with a foot switch.
Specifications
The pelletizer GTE (300 mm diameter, 9.5 litre) is attached to the AR 403 via universal gear (UG), which enables the operator to adjust the operating angle to the optimal position during operation. The material can be fed in manually or continuously. The rotary movement of the pan carries the product to the top of the pan and then flows down the pan in an even stream to the base.
By addition of the requisite amount of liquid, this process can be converted into the formation of pellets. The angle of the pan and the amount of liquid added determines the pellet size. When the pan is full, the pellets will continuously roll over the edge of the pan into a waiting container. All parts coming into contact with the product are made of stainless steel.
Specifications
The Cube Mixer KB uses a tumbling motion to produce a homogenous blend within a short time. The mixing action is assisted by three stainless steel rods strategically positioned within the cube. The cube mixer is attached to the drive unit via the ERWEKA Universal Gear UG, which permits operation at various angles for optimum efficiency. The cube mixer is available in several versions of acrylic glass or stainless steel.
Our cube mixers are available in the following versions:
Polishing Drum to polish coated tablets. The drum is covered with interchangeable felt parts. The cover has a 120 mm diameter opening for observation of the polishing process and addition of the polishing agent during the production process. The polishing drum has 2 l volume with a working capacity of max. 40%. The device is attached to the drive unit via the ERWEKA Universal Gear UG, which permits operation at various angles for optimal results.
Specifications
The planetary stirring unit for mixing of creams, ointments, pastes, moist powders and liquids. This powerful mixing attachment comes with various mixing / stirring accessories e.g. kneading hook, mixing paddle, whisk and a fluoropolymer scraper for removing any product adhering to the side of the bowl, thus ensuring a homogenous mixing in the shortest possible time.
The stirring / mixing accessories and vessel (5 liter volume, working capacity 60 %) are made out of stainless steel. Optionally an electric heated bowl DER or a double jacket bowl DB for heating and cooling by water are available. An emergency stop helps to prevent injuries.
Specifications
The drum hoop mixer with diagonal placement of the drum within the hoop. The rotation of the hoop itself produces a uniform, three-dimensional displacement of the material to be processed and hence a tumbling mixing action.
The mixer consists of two parts: the drive support and drum hoop with acrylic mixing drum. As an option, an extended drive support for simultaneous use of two mixers of the same size is available in lengthened version (RM 5 volume, working capacity max. 40 %).
Specifications
