Saudi Arabian Mining (Ma'aden) will ramp up phosphate production from its new Waad al-Shamal facility by mid-2017 as the kingdom seeks more cash from non-oil sources, Reuters reports. At full capacity in 2019, the complex will roughly double Saudi's phosphate production to 6Mtpa, putting it joint-6th globally.

Thus the engineer can fit any one of fifteen variations of sizes and type of discharging a rod mill, into the problem on which he is working.
The superiority of the Steel Head Rod Mill is due to the all-steel construction. The trunnions are an integral part of the cast steel heads and are machined with the axis of the mill. The mill heads are insured against breakage due to the high tensile strength of cast steel as compared to that of the cast iron head found on the ordinary rod mill. Trunnion Bearings are made of high-grade nickel babbitt, dovetailed into the casting. Ball and socket bearings can be furnished if desired.
The following table clearly illustrates why Steel Head Rod Mills have greater capacity than other mills. This is due to the fact that the diameters are measured inside the liners, while other mills measure their diameter inside the shell.
Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 28243 feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations. Under wet grinding conditions of course the problem of dust is eliminated.
The Rod Mill encourages the use of a thick pulp coating both the liners and the rods, thus minimizing steel consumption. Continuous movement of the pulp through the rod mass eliminates the possibility of short circuiting any material. The discharge end of the Rod Mill is virtually open and larger in diameter than the feed end, providing a steep gradient of material flow through the mill. This is described in more detail on pages 20 and 21.
End Peripheral discharge and center peripheral discharge rod mills are described in detail on pages 28 and 29.
Feed and discharge heads of Rod Mills are conical in shape providing important advantages over a mill with straight heads.
The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus. The SAGMILLING.COM models expect a mill with a wave liner, and is not compatible with mills using smooth liners. Most laboratories outside of Australia use the wave liner style of machine 8211 these results can safely be used in the models. Bond rod mill work index results from Australian laboratories with smooth liners should not be used in the SAGMILLING.COM models.
The test is a locked-cycle test where ground product is removed from test cycles and replaced by fresh feed. The test must achieve a steady-state before completion.
The test requires about 15 kg of material. Although it can work on feed as fine as 10 mm, it is best to send material to the testing laboratory that is nominally at least 25 mm including the natural fines that are part of the sample. The laboratories have a standard way of reducing the coarse material to the roughly 10 mm size used to feed the test that will not introduce excessive fines.
When WiRM is used to size SAG mills, the BondBarratt model assumes a 14 Tyler 1180 181m closing mesh size 8212 the engineer should specify this closing mesh size to the laboratory performing the tests. When used to size rod mills, the engineer should specify the target product size for the industrial plant the laboratory will choose an appropriate closing screen mesh size to achieve that product size.
Rod mill work index is used in the SAGMILLING.COM BondBarratt specific energy consumption model.
The work index is used to calculate the energy requirement to grind rocks in the medium size range, from 10 mm - 20 mm down to about 2 mm.
The finishing stand of a bar mill gives the bar its final shape and often a specific surface pattern, such as the protrusions on concrete-reinforcing bars. The rolling speed increases as the cross section at each successive stand decreases, and the exit speed can be as high as 15 metres per second. The hot bar is then cut by a flying shear into cooling-bed length e.g., 50 metres, after which it is cooled, inspected, and cold-cut to shipping length.
Computers are used for designing roll passes and for scheduling and controlling the complex operations. Bar and rod mills produce 150,000 to 750,000 tons per year. The largest mills are housed in buildings up to 600 metres long. The most space-consuming part of these manufacturing facilities and the source of most bottlenecks is the finishing and shipping area, which handles the many different lightweight shapes that are produced in various steel grades, heat treatments, and surface conditions and are made to many specific customer orders.
These are long products with irregular cross sections, such as beams, channels, angles, and rails. Rolling starts with blooms that may be 150 millimetres by 200 millimetres by 5 metres long. The blooms are received, either cold or hot, directly from the blooming mill or continuous caster. They are charged into a pusher or walking-beam continuous furnace and heated for up to three hours to 1,200 C. Sometimes, three batch-type furnaces are used instead.
Most shapes are formed by grooved rolls with mating projections that form together a window in their gap. This window becomes progressively smaller and more like the desired shape, pass after pass, until at the end, in the final pass, the specified cross section is obtained. D in the figure shows only 5 progressive passes out of about 11 in the rolling of a rail. Rolling shapes usually takes a total of 9 to 15 passes, with an area reduction of about 25 percent at the initial passes and only 7 percent at the last pass.

This specification ismanufactured from low-carbon mild steel and covers your everyday, run of the mill bolts. Stockfinishes include plain black, zinc plated, and hot-dip galvanized. One end of each rod requires a permanent grade symbol and manufacturer8217s identifier, however this requirement is largely ignored due to their implementation in noncritical applications and the fact that they are often cut to length in the field.
This low-carbon, mild steel bolt specification covers heavy hex bolts and fully threaded studs that are intended for cast iron flanged jointsin piping systems with cast iron flanges. A307 Grade B differs from A307 Grade A in that it has a maximum tensile strength requirement. Common finishes include plain black, zinc, and hot-dip galvanized. One end of each rod requires a permanent grade symbol and manufacturer8217s identifier.
