What is a cement silo?
Cement silos are on-site containers that are generally used for storing and distributing different types of cement mixtures. Cement silos are available in a variety of sizes, making these perfect for use in almost all kinds of construction sites. Another noteworthy fact is that the silo can be both a permanent structure as well as a portable one that can be easily relocated to places where required. As is the case with other types of silos, cement silos are also equipped with some kind of blower for expelling the stored materials into a truck or some other place.
Typically, the silo can be structured in many different ways so as to hold a few tons of dry cement product or to hold several hundred tons. Since larger silos hold several hundred tons, these are generally fixed at a specific place. Another noteworthy thing here is that smaller cement silos are used in a majority of construction sites so as to enable these to be moved around as and when required.
Some facts about cement silos:
- As mentioned above all silos are equipped with blowers. These blowers are sometimes propelled by electricity or sometimes gasoline
- As for portable silos, their blower equipment takes minimal time to set up and can also be stored easily when not in use
- Materials and the design of a cement silo will always differ, depending on which kind of cement product is to be stored.
Cement silo maintenance:
Generally cement silos are set up outside and do not get the requisite attention towards their maintenance. Also, environmental regulations in a majority of countries indirectly necessitates the maintenance of cement silos. In some parts of the world an annual certification for these silos is essential.
Regarding the maintenance of cement silos, below are some points that should be kept mind and adhered to,
- The bag house filter of the silos should be replaced every year at the least. This should also be done if the silos have a venting problem or too much dust coming out of the relief valve
- Also periodically check if the shaker or vibrator mounted to the top bag support rack is operating properly
- Periodically inspect the relief valve on top of the silo and ensure that the valves are moving freely without any obstruction
- Every bearing and drive of the cement silo should be checked to make sure that they are in a good condition and have been greased.
- Check the discharge auger to make sure it is clean of cement buildup
Generally cement silos manufacturers before making the silos take into account some factors such as how much material will be stored, does the material being stored has some unique characteristics, does the material to be stored has a tendency to degrade etc. Silo manufacturers in the past have been blamed for following an archaic approach in which they tend to process customer information relative to their standard storage products and also design parameters. As for current manufacturers, they have improved quite a lot and now a days consider every aspect of silo use before designing these.
Cement silos are basically constructed through:
- Bolted smooth wall flat panel construction
- Hybrid silo construction
Each of the above mentioned methods have specific features, with manufacturers choosing either of the two based on what they deem fit and also for what application the silo is intended.
Major applications of cement silos are
- Construction facilities(both small and large)
- Maintenance and repair sites
- Transport of cement from one site to another
