Concrete plant owners and operators know the problems of dust collection. From the first startup permitting and paperwork related to the dust produced at concrete plants through the ongoing maintenance and replacement of dust filters and equipment years after you have been in business, dust collection and suppression is a significant element of the system. The laws and rules regarding dust collection and suppression requirements vary town by town, county by county and even state by state. Additionally you could have various agencies that you’ll require to manage including local zoning authorities, DNR, EPA and others depending on your location. Fortunately the equipment used for collecting and suppressing dust related to concrete plants has continued to boost and is now very effective.
Dust collection and suppression must certanly be considered at several different aspects of the concrete plant. Some owners will put equipment to gather and control dust in every area where it can be created. Others owners is only going to put the collection equipment where it is absolutely required. Many owners will use more dust collection equipment then required because they want to be eco-friendly, appease opponents, or for other reasons. Ultimately your decision on what sort of dust collection equipment you will need is founded on that which you want to accomplish and what sort of concrete plant you have.
At ab muscles minimum concrete plants can be purchased standard with a dust vent on the cement silos, usually a number of per compartment. When cement is delivered in a bulk tanker it is pneumatically blown from the tanker into the silo. A silo being filled with a bulk tanker nebulizzazione ad alta pressione without the venting system standard on most silos looks as though the silo is on fire. Cement, fly-ash and slag (the most frequent materials in silos at concrete plants) are aerated commodities. Which means when air is introduced into the material it becomes lighter and flows easier. When these materials are pumped into the silo’s from a tanker the dust collector keeps the materials from flowing into the environmental surroundings looking such as a thick smoke. In case of silo dust collectors they really provide operators with a cost savings since it keeps them from losing massive amount materials being delivered.
Another common place for dust collection equipment is where the materials discharge into the mixer. Precast and product plants will commonly have a dust collection system integrated with their plant mixers. Ready mix plants frequently have a dust collection system that helps contain and control the dust around where the truck connects with the plant. Areas that are often built with dust collectors include weighing hoppers like a cement batcher. Some locations are even forced to regulate the dust from trucks on gravel drives and areas using water trucks to help keep the area moist and dust in order as trucks travel through.
Obviously understanding the areas on and around your concrete plant that are problem areas for dust creation as well us knowing what environmentally friendly and zoning requirements related to dust are among the most crucial factors in selecting dust collectors and suppression equipment. Another important factor is developing the strategy for controlling the dust. Some plants work with a different dust collector for every single area they need to control. Central dust collectors will also be available that use ducting systems to gather dust from multiple areas and vent it to an individual centralized dust system. Some concrete plants use a mix of systems. There isn’t necessarily a right or wrong system, it is merely selecting the correct system for your application.
