We are undertaking a scientific project to establish the design norms for local exhaust ventilation system for dust control in the mineral handling/ beneficiation plants and coal washeries in India.

Please confirm if u can provide appropriate system for the following: A direct online reading system for (i)particulate concentration and (ii)particle size distribution in ambient air and work zone environment. The dust concentration in the work zone is not likely to exceed 10g/m3. The partcle size are in the range 0.2 to 50 microns

We also need a high speed video camera (50 picture/minutes or more) to capture the image of dust cloud in mineral handling/ beneficiation plants. The camera should have a software to enable to study the dust cloud in slow motion on a monitor. The purpose is to measure the particle size of dust and volume and speed of dust cloud.

You may also kindly indicate (i)the cost of the system and shipment time for exporting the system to India. The address of ur agent in India, if any, may also be furnished to us. ■
