Here is a list of Rules of Thumb often used in Rock Crushing and around Crushers: Crusher Selection For a hard rock mine application below 600 tonnes/hour, select a jaw as the primary crusher. Over 1,000 tph, select a gyratory crusher. Between these capacities, you have a choice. Source: Chris Ottergren For a hard rock mine application below ...
During beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers. This reject mostly contains low tricalcium phosphate (TCP) content and high carbonate content. In this work, pilot scale experiments have been carried out to reduce the carbonate content by leaching the ground phosphate rock with dilute ...
The type of rock you plan to focus on processing in your operation will dictate the types of rock crushers you'll need to include in your crushing circuit. The more you know about the type of rock you wish to crush and what its end-use will be, the easier it is to choose the best equipment to achieve your project goals .
Crushers can be divided into three categories according to the size of feed and product: Coarse crusher: crush from 1500~500mm to 350~100mm; Medium crusher: crush from 350~100mm to 100~40mm; Fine crusher: crush from 100~40mm to 30~10mm. Below we will introduce the commonly used grinaite crushing equipment in each stage according to coarse, …
Crushers are key equipment in mining, construction and aggregate industries. They break large rocks, ore, or other materials into smaller, more usable pieces. This equipment reduces the material by means of compressive force, impact, attrition or shear that are specific for the type of crusher being used.

Phosphate rocks are a vital resource for world food supply and security. They are the primary raw material for phosphoric acid and fertilizers used in agriculture, and are increasingly considered to be a potential source of rare earth elements. Phosphate rocks occur either as sedimentary deposits or igneous ores associated with alkaline rocks. In both cases, …
Phosphate Beneficiation. Market Specifications Bone phosphate of lime, 70 to 72 per cent, common. Bone phosphate of lime 72 to 77 per cent, premium. Production Problems. Phosphate rock being a low-priced material is produced as near the fertilizer market as possible and haulage costs determine production.

Next, these fragmented rocks are loaded onto trucks or conveyors and transported to a primary crusher. This crusher is typically a large machine with deep jaws or plates that exert pressure on the rock, breaking it down further. Once crushed, the phosphate ore rock is then conveyed to secondary crushers where further reduction in size occurs.

Phosphate rock is mostly produced in sedimentary rocks, but also in metamorphic rocks and igneous rocks. Except for some cases, phosphorus in minerals always exists in the form of orthophosphate, and the main mineral of phosphorus is apatite. Phosphorus is an important chemical raw material and an essential element for the growth of crops.
Phosphate was first discovered in Jordan at the turn of the present century during the excavation of railroad cuts in the Ruseifa and El Hassa areas. In 1977 these two areas are still the sites of the total present phosphate mining in Jordan. Underground mining methods were used at both sites in the past but currently all mining is open pit.
