• Settling And Compacting Product At A Pharmaceutical Company

  Problem

  A West Coast pharmaceutical company had a weighing and packaging machine that required employee intervention with a tapping hammer in order to settle the contents properly.

  Situation

  The capsules or tablets were loaded into five-gallon buckets, but the weighing and packaging machine does not have a vibratory table. In order to properly settle the material and pack these containers, one full-time employee must constantly tap on the sides of the container with a rubber hammer. Furthermore, the line required 24-hour continuous operation to meet consumer demand and the equipment would reside in a high wash down environment.

  Solution

  Martin Vibration Systems installed a MARTIN^® NTP™ Continuous Impacting Linear Vibrator providing precise and controlled air vibration solution, while meeting the high wash down and non-stop requirements of this capsule packaging line.

• Increasing Efficiency by Eliminating Blockages

  A customer working with large amounts of wood chips was experiencing difficulty completely unloading the trucks delivering the material. Once the wagon silo was turned over the container, the wood chips passed through a sieve grate that prevented the largest pieces from falling into the container. However, the large wood chips tended to block the flow through the grate openings, causing them to build up. The small chips were also very likely to accumulate on the grate. As a result, workers were required to manually break up the blockages.

  The customer purchased and installed a MARTIN^® NTP™ Pneumatic Piston Vibrator. The vibration eliminated the accumulation of small pieces and allowed the smaller wood chips to flow through, while leaving the large pieces on top of the grate. This in turn substantially reduced downtime because workers no longer had to manually break up the blockages.

  

  
• MARTIN® Stick & Shake™ with NTP™ 18 Clears Bridging in Powder Hopper Without Welding

  Situation

  A client’s operation involves discharging fine powders from hoppers, a process often disrupted by material bridging. However, modifying the hopper structure with welding or drilling was not an option due to equipment warranties and sanitary requirements.

  Problem

  Bridging at the hopper outlet caused repeated flow stoppages, requiring manual clearing with mallets or rods. This not only introduced safety risks for their operators but also slowed production and increased wear on the equipment.

  Solution

  The client applied the MARTIN® Stick & Shake™ Adhesive Mounting System to securely mount a vibrator without any permanent modifications required. Once the adhesive mounting plate was cured in place, they installed the MARTIN® NTP™ 18 Continuously Impacting Linear Vibrator. This model delivers powerful, repeated linear impacts — ideal for breaking up stubborn powder bridges in flow-resistant materials.
