Industrial vibrators are widely used in concrete batching plants where
there are holding bins, silos and open bins to store bulk material including fly
ash, sand, gravel or aggregates.
Dust control guidelines mandated by environmental protection agencies often
require these materials to be maintained in a condition that prevents excessive
dust being generated during loading and unloading operations. This requires the
bulk materials to be kept in a moist condition. Adverse weather conditions can
cause the holding bin or silo to sweat drawing moisture into the holding
material and making it difficult to flow. Additionally, natural compaction can
affect the material’s flow characteristics leading to the material being
trapped within the bin or silo.
Industrial vibrators are designed to address the primary problem of
making these bulk materials flow in a simple, safe and speedy manner while meeting
EPA guidelines for both dust and noise pollution. Electric or pneumatic
vibrators are widely accepted for advantages such as ease of installation and
cost effectiveness. Turbine vibrators also offer an efficient solution as they
operate at higher frequencies and require almost no maintenance.
Enmin Vibratory Equipment was asked to provide a solution for a concrete
batching plant in Australia that was using a steel holding silo. A turbine vibrator
specified by Enmin was attached to the silo and operated at 10,000 vibrations
per minute, transferring high frequency low amplitude forces into the material
to break the particle bonding and promote flow of the material.
The turbine vibrator was positioned correctly by Enmin to ensure
effective operation after installation. Since these vibrators do not require
lubrication, maintenance is minimised for the customer.
Following the successful installation and performance
of the turbine vibrator, this particular client decided to install seven additional
units throughout their concrete batching plants.
