Drum Weigher & Mixing System for 600 Litre Drums
WML/100/350-1310/M
Drum Weigher & Mixing System Description
This drum weighing and mixing system was designed for a pharmaceutical processing
company. The drum weighing and mixing system was fitted with a manually operated
hydraulic lifting arm to raise and lower the Ytron mixer into a drum with a Safe
Working Load of 100 Kgs. The whole drum weighing and mixing system was mobile on
castors and the base of the system incorporated a Stainless Steel Weighing Platform
onto which empty drums were loaded for filling and mixing. The weighing facility
was designed to accommodate a load of 1000kgs with a weighing accuracy of + 1.0kgs.
The whole drum weighing and mixing system was manufactured from Grade 304 Stainless
Steel and was able to pass through an 800mm wide x 2650mm high doorway. The electrical
control system incorporated an inverter to provide adjustment of the mixer speed,
together with a safety system that would only permit the mixer to be operated if
a drum was loaded to the machine and the lift was in its full down position. All
of the electrical equipment was mounted in enclosures rated to IP65.

Drum Weigher & Mixing System Application Story
The application for this drum weighing and mixing system was to mix various powders and/or liquids into a specified volume of water. The water was added to the drum first and because the drum was placed onto the weighing scale, the amount of water could be measured accurately. Various other items were also added using the weigh scale or where a particularly accurate requirement existed, the ingredient was weighed on a bench mounted scale and then added to the mix. The Ytron Mixer was then lowered into the mixture and mixing commenced until a thorough mix was achieved.
The fact that the weighing and mixing were incorporated into this one drum weighing and mixing system meant that the full drums which could weigh as much as 600 Kgs did not have to be moved from one position to another for the water and various other ingredients to be added. This drum weighing and mixing system also negated the requirement for a floor mounted scale with a pit and drainage in a clean room environment. Once the mix was complete the whole drum weighing and mixing system could be wheeled to a discharge position for the drum to be emptied by a pump.
