One piece silicon carbide liners for hydrocyclones, slurry pipe, pumps and pressure oxidation vessels.
Ore slurry wears through cones, spigots, bends and pump casings.
Cast ceramic liners that go in as one piece and wear evenly.
In mining and mineral processing, the ceramic wear parts that last longest in slurry are one piece silicon carbide liners: cones, apexes, spigots and inlet scrolls for hydrocyclones, lined pipe and spools for slurry and tailings, and liners for pump components. Blasch casts them as monolithic drop-in parts up to 60 in diameter in ALTRON, NITRON or reaction bonded InVinCer silicon carbide, so there are no tile joints for the slurry to open up. For autoclaves and pressure oxidation, the same process makes large NITRON linings for flash vessels, quench vessels and impingement blocks.
Most cyclones and slurry lines are still lined with tiles or segments held in place by epoxy. The joints are where wear starts, and installation takes skilled hands.
Hydrocyclones classify coal, iron ore, gold, copper, phosphate, cement and FGD slurries. Blasch works with OEMs and with single mines to keep classification efficient and cyclone life long, with one piece cyclone liners and matching vortex finders.
Slurry and tailings lines wear at bends, reducers and valves first. Lined pipe and spools up to 7 ft long and 3 ft in diameter, in-line chokes and reducers and lined valves carry the same ceramic through the system.
Worn pump parts can be refitted with ceramic: the suction side, impeller and volute liners are cast in reaction bonded silicon carbide or ALTRON. Ceramic pump components
A cyclone liner that wears evenly keeps its cut point, so the circuit behind it keeps its recovery until the liner is changed on schedule.
Autoclave and pressure oxidation plants keep growing in size and operating pressure. Blasch casts complex NITRON linings that resist heat, abrasion and corrosion at the same time.
Typical parts are flash pots, quench vessels, choke tubes, vent blast tubes, oxygen injection nozzles and impingement block linings, plus pipe and valve systems for the hot slurry.

The same lined pipe moves ash in power plants and dry bulk in heavy industrial processing.

Both are used. Silicon carbide grades such as ALTRON, NITRON and InVinCer RB handle coarse, fast moving particles and heat well; dense alumina suits finer slurries. The ore and the velocity decide.
Blasch makes one piece hydrocyclone linings from 1 in up to 60 in diameter.
Yes. Liners are designed as drop-in parts from the dimensions of the existing component, so no drawing is needed to start.
No. It is a cast ceramic part with its own wall, fitted inside the steel housing or pipe, not a layer sprayed onto it.
Send the cyclone or pipe size, the ore and the current liner life. A Blasch engineer suggests a silicon carbide grade and a liner shape.
