Concrete plant owners and operators know the difficulties 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 held it’s place in business, dust collection and suppression is an important part 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 may have various agencies that you might want to manage including local zoning authorities, DNR, EPA and others depending in your location. Fortunately the equipment used for collecting and suppressing dust related to concrete plants has continued to improve and is currently very effective.
Dust collection and suppression must certanly be considered at a number of different aspects of the concrete plant. Some owners will put equipment to gather and control dust atlanta divorce attorneys area where it could be created. Others owners is only going to put the collection equipment where it is completely required. Many owners uses more dust collection equipment then required because they would like to be green, appease opponents, or for other reasons. Ultimately your decision on what sort of dust collection equipment you need is founded on everything you are attempting to accomplish and what sort of concrete plant you have.
At the very minimum concrete plants can be bought standard with a dust vent on the cement silos, usually one or more per compartment atomizzazione polveri. When cement is delivered in a bulk tanker it’s pneumatically blown from the tanker into the silo. A silo being filled by a bulk tanker minus the venting system standard on most silos looks as although 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 the tanker the dust collector keeps the materials from flowing into the environment looking just like a thick smoke. In case of silo dust collectors they actually provide operators with a price savings since it keeps them from losing wide range of materials being delivered.
Another common area for dust collection equipment is where in fact the materials discharge into the mixer. Precast and product plants will commonly have a dust collection system integrated making use of their plant mixers. Ready mix plants frequently have a dust collection system that helps contain and control the dust around where in fact the truck connects with the plant. Other places which can be often designed with dust collectors include weighing hoppers such as a cement batcher. Some locations are even forced to manage the dust from trucks on gravel drives and areas using water trucks to help keep the location moist and dust under control as trucks travel through.
Obviously understanding the areas on and around your concrete plant which can be problem areas for dust creation as well us knowing what the environmental 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 make use of a different dust collector for every area they have to control. Central dust collectors are also available that use ducting systems to gather dust from multiple areas and vent it to a single centralized dust system. Some concrete plants use a mix of systems. There isn’t necessarily the right or wrong system, it is merely selecting the appropriate system for the application.
