Anonymous Poster	Air Blower Design 10/04/2010 2:18 AM
	Hi, I would like to seek the help of the forum. May i know how do i start designing an air blower( to blow micro material silca to the top of silo height 25m x 4m horizontal spacing beetwen our blower and the silo)? As in, from where do i start ? Basically, i am hoping that someone would enlighten me the list of steps from the start till the end in air blower design. I am really confused as to where to start and what should be included in order to design it. Any help would be very much appreciated. : kinds regards,

	How is the silica handled at the moment? Silica is not the sort of material you want to be blowing anywhere due to the respiratory problems it can cause. Crystalline silica is linked to the industrial disease silicosis. Blowing the product to a bunker isn't a great problem. Handling the air when it gets to the bunker is. Filtration will probably cost as much if not more than the blower and handling equipment. __________________ The reports of my death are greatly exaggerated.

	Easy -To do this you must first know what a blower looks like, then calulate to find what capacity and hp you need. this is for your start. After this call a blower supplier and buy one. Dismantle it part by part , measure each part and design. Simple. So do not get confused. let us know after this stage to guide you. __________________ I not only use all the brains that I have, but all that I can borrow. Woodrow Wilson

	The first step is to determine the velocity at which the air flow will transport your silica particles (depends on particle dimensions). This will give you an idea about the air flow and what type of blower you need. After that you follow the indications of the precedents. For the separation you can have a cyclone which is efficient if the silica is dry. Again the cyclone type depends on the particle dimensions.

	I agree with Tony S., silica is a dangerous material, keep the dust down. See if 25 m is not too much for a screw conveyor. They are simple and durable. Even if you had to stack them, I think it would take less energy to do the job. __________________ mike k
