Đó là vì lý do này mà hầu hết Máy nghiền đá nằm dọc theo ngoại vi của thành phố hoặc trong vùng lân cận của chính xây dựng dự án. Trong hầu hết trường hợp, Máy nghiền đá đi lên trong cụm số đơn vị khác nhau, 5-50 trong một cụm. Các máy nghiền được đặt gần nguồn nguyên liệu như: mỏ đá, ngủ sông. Những máy nghiền đá mặc dù kinh tế xã hội một ngành quan trọng, cho phép tăng số lượng đáng kể phát thải bụi mịn kẻ chạy trốn mà tạo ra mối nguy hiểm sức khỏe công nhân cũng như. | AMERICAN NATIONAL STANDARD ANSI Formerly ANSI Fossil Fuel Power Plant Steam Turbine Bypass System Approved 15 December 1999 ANSI Fossil Fuel Power Plant Steam Turbine Bypass System ISBN 1-55617-711-9 Copyright 1999 by the Instrument Society of America.

The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general and the International System of Units SI in particular in the preparation of instrumentation standards. The Department is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI and the metric system in their business and professional dealings with other countries. Toward this end this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards recommended .
