Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.

ANFO (or A mmonium Nitrate/Fuel Oil) is a widely used bulk industrial explosive mixture in mines and quarry operation. It consists of 94 % porous Ammonium Nitrate (NH 4 NO 3 ), (AN) that acts as the oxidizing agent and absorbent for the fuel – 6 % number 2 fuel oil (FO), popularly known as High Speed Diesel (HSD).

This way, all the raw material will be easier to handle, easier to transfer from place to place, and overall, easier to work with. Crushers are powerful machines that have an elaborate system of jaws, vibrators, and steel plates that crush material from the quarry. The whole crushing process will result in raw materials in the desired quality ...

A quarry may need several explosives supervisors to cover all the work, for example where blasting takes place on several shifts. If this is necessary for the working of the quarry: d) There may only be one person acting as the explosives supervisor at any time; e) All explosives supervisors must be familiar with the shotfiring operating

Explosive and Toxic Hazardous Materials. New York: Macmillan Publishing; 1970: 24. dium. The shock wave moving through the explosive material causes further explosive decomposition of that material, and the reaction rate is determined by the speed of the shock wave. The range of velocities of the shock wave is 1,000 to 9,000 m/sec. In addition to

In most cases, bulk explosive trucks mix raw materials (sometimes called pre-cursors) to deliver ANFO, Heavy ANFO and Emulsion/AN mixtures which may be sensitized chemically or mechanically, or unsensitized. There are several types of trucks available that are built specifically for the environments they need to be used in, including open cut ...

It essentially hinges on the ability of a drill to contribute to the quantity and proper sizing of the raw material when combined with the proper blast design and execution of that design in the field. No amount of explosives expertise and technology can overcome a hastily and ill-informed selection of hole diameter, drilling method, and drill rig.
