EVOLVING IMPROVED & ADVANCED DESIGNS OF DUST CONTROL SYSTEMS FOR STONE CRUSHERS
Upon reviewing the existing Environmental Standards & Guidelines, subsequent Amendments and after reviewing status of dust control systems installed by many stone crushers and reasons for their failure to achieve desired level of dust control & local constraint etc., new improved designs of dust control system have been evolved which would be simple to install, operate and maintain. Various aspects of the designs are discussed in following pages
8.1 Basis/Criteria for evolving the Advanced Designs
1. The system should be low cost and affordable by stone crushers
2. The system should operate in the dusty condition
3. The system should be easy to install, operate & maintain
4. The system should not affect the product stone quality adversely
5. The system should be indigenously available or fabricated preferably locally
Based on the above criteria three types of design have been evolved for different types & sites of stone crushers. The types of design namely (i). Wet type system (ii).Dry type systems (iii). A combination of Wet and Dry Type System. The design details of each of the systems along with its applications areas are briefly described below.
8.2 Wet Type Dust Control System
This design has two components (1).Dust Containment Enclosure Component & (2). Dust Suppression System Component
