Dust And Skirting @ Load Station
Dear Sir
Fugitive dust, at load points, can be controlled in three ways:
1. Curved Chute Configuration:
Dont generate pneumatic pressure gradient. The granular flow stream creates the turbulence during ore free fall between head discharge pulley and receiving conveyor. Gravity acceleration during free fall then quick deceleration during impact first sucks in gas into flow stream then expuges gas on impact. We can quantify the gas turbulence gradient throughout the chute volume. Curved chute geometry significantly reduces the stream velocity gradient and thereby pneumatic plunging.
2. Sealing Skirt
Dont allow belt to lose contact skirt rubber. This is accomplished with a special load point design we have implemented in hard rock. The design combines the concept of a slider bed with a roller bed. We only use the slider under the skirt. The impact table still uses rollers. The slider bed does not allow the belt to vertically displace but can articulate along the plane of the belt wing roll support. No spillage and no dust.
3. Dust Collection
Suck it and see - no dust just big expense to install and maintain.
We will be posting some of these design concepts on ou website 2002.
Merry Christmas.

Re: Skirting System
Dear Achmad,
I presume that you want to contain dust with skirting, not eliminate it. To do this a system approach is best. That is, do not just look at the skirting -- but examine chuite design, drop height, impact system (idlers, slider bed, combination, etc.), dust shields, venting, etc.
I suggest that you contact Martin Engineering for design concepts at www.martin-eng.com or companies such as ContiTech, Rema, or Pang,. The last three companies all manufacture high quality skirting material.
If you have experience rapid skirting wear, it could be due to your skirting arrngement, or it could be due to the use of an inferior skirting rubber.
Feel free to contact me if you need to discuss particulars.

Conveyor Equipment Manufacturer
JIM WAY ENTERPRISE CO., LTD. INTRODUCTION
Dear Sir,
We are a professional manufacturer major in Idlers, Belt Cleaners, Skirt Rubber, Impact Bar, Pulley, Wear-Resistant Ceramic Lining Plate, and other Belt Conveyor Accessories, we established in 1981 and have an excellent reputation through more than 22 years manufacturing experience, especially in the solution and manufacturing of the conveyor idlers, belt cleaners, and etc; then we have got the certificate of ISO 9001.since years ago.
The JIM WAY products have been widely adopted by Taiwan Power Company, Mining Company, Cement Industry, Iron & Steel Corp. and industries which request rigorously quality on conveyor system. Therefore, we have dedicated to research the way to surmount the traditional steel idlers restrictions; Now, one of our most outstanding product that we had surmounted successfully is the Superior Polymer Idlers., which are made by superior polymer pipe, set with the high quality bearing and our peculiar design of 4 layers multilabyrinth that is excellent for dust and water proof, they are all tested by international rules, standardized CEMA, JIS and DIN and guaranteed by our company, The improved idlers are strongly suggested to the anti-acidic, alkaline and corrosive working sites. they are lightweight, low friction, impact resistance, anti-static and economic. Which are convenience to be applied to Concrete, Cement, Quarry, Limestone, Fertilizer, Salt, Sugar, Pulp fields and etc.
By the other side, our patented belt cleaners are very competitive internationally as well as its price, which are designed with autocompensation & shock-absorption spring tension regulator and the pressure scaling indicator that make more efficiently to install, maintain, or replace it.
Therefore, if you want to know further information or inquiry, pls just feel free to ask us, we are always glad to be in the service for you and look forward to any kind of your partnership.
In case of saving your precious time, I sincerely wish you could visit our web site: http://www.roller.com.tw

Skirting system
Dear All,
Please inform us skirt material to prevent dust in receiving chute station. Are the skirts including consumable material and how many time are we replacing it regularly.
Also we would like to know supplier of skirt material.
