Where does it come from? The crushed dolomite rocks are mined from Barangay Pugalo in the small town of Alcoy, south of Cebu, by Dolomite Mining Corporation (DMC) as part of the 25-year Mineral Production Service Agreement between DMC and the local government of Cebu. However, this "agreement" hasn't exactly been smooth-sailing.
Dolomite. Also known as dolostone, dolomite is similar to limestone, and these rocks are often mined together at a quarry. However, dolomite is harder than limestone, making it more durable to abrasion. Most people rarely use the term "crushed stone" and instead refer to both gravel and crushed stone as "gravel."
bonate begins. Decomposition does not progress at a rapid rate, however, until a temperature range of 700 - 800° C is reached for dolomite and 830 - 930° C for high-calcium stone.1 The loss of carbon dioxide during calcination leaves the residue in a porous, highly re-active state. It is usually the desire of the manufacturer to remove the lime
crushed rock industry is a major contributor to and an indicator of the economic well being of the nation. Forms Of Crushed Rock About three-quarters of the crushed stone production is limestone and dolomite, followed by, in descending order of tonnage: granite, traprock, sandstone and quartzite,
Dolomite is a sedimentary stone, which means it was formed on the surface of the earth, as opposed to granite, for example, which is formed in magma chambers under the earthʼs surface. It can be found in abundance all over the world (as is the case in the Dolomite Alps in Italy) in sedimentary basins —which are warm, shallow, marine areas ...

The crushed material is sieved by the vibrating screen. The finished material is output by the conveyor. If the material does not meet the specifications, it will continue to return to the impact crusher and break again. Equipment configuration: PE-400×600 jaw crusher + PF-1010 impact crusher.
It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill. It is also calcined in the production of cement and cut into blocks of specific size known as "dimension stone." Dolomite's reaction with acid also makes it useful.
Through this, it will wash-away all the black-colored sand or it will be hidden by the crushed Dolomite. In my fact-based opinion, the DENR's solution to Manila Bay's problem is ineffective and inefficient—the reason why I am against with it. Aside from it is unnecessary to put crushed dolomite into it, it costs 389 Million Pesos.
Responding to observations that the crushed dolomite was washed out to sea just days after being dumped, he said it's normal. He also claimed that the sand on the artificial beach won't be washed away by storms and large waves because the department has installed geotubes, and submerged machines, around the perimeter of the man-made beach.
Pattison Crushing plant overview. Curious about what happens when the stone becomes Dolomitic? Well, not surprisingly, Dolomitization causes a few structural and composition changes in the rock. The process that Limestone goes through to become Dolomite creates a slight volume reduction, resulting in a porous, trigonal-rhombohedral structure.

The possible presence of toxic heavy metals and silica dust in the crushed dolomite rocks dumped at the Manila Baywalk may cause cancer, respiratory and kidney problems and subsequently weaken the immune system, a toxicologist had warned.

Depending upon magnesium levels, dolomitic lime can often cause more harm and trouble, however, than its initial cost. Excess magnesium is often associated with soil stickiness, crusting, compaction, reduced aeration, and releasing nitrogen from the soil pound for pound.
The term "g ravel" gives almost no information and does not even describe the type of rock. z One way of determining crushability is to measu re the energy required to crush a material. ... Dolomite 0.02 Basalt 0.25 the most suitable machine or wearing part Diabase 0.28 alloy.

Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 65 million years in age).
