铈铌Perovskite (former Soviet Union)

First, the nature of the ore
Cerium, niobium former Soviet Kola Peninsula in an alkaline mineral perovskite Ni nepheline syenite and nepheline syenite anisotropy in a rare earth-containing, niobium, titanium complexes. The main chemical components of this mineral: REO 28.71%, ThO 2 0.52%, Nb 2 O 5 9.4%, Ta 2 O 5 0.38%, TiO 2 36.83%; mineral density is 4.64 ~ 4.89 g / cm 3 ; The strontium perovskite has weak magnetic properties. The ore contains strontium perovskite from 3.53% to 3.70%, and the associated gangue has nepheline and neon. The useful mineral inlays in the ore are coarser in grain size and can generally be recovered by re-election and magnetic separation.
Second, re-election - magnetic separation process and selection indicators
The ore transported from the mine is crushed to -20 mm by a two-stage crushing process. After a period of grinding mill to -1 mm, the hydraulic grade is graded, the coarse fraction is sent to the jigging, and the jigging tailings are returned for re-grinding. The fine-grained grade is selected by a shaker. The obtained nepheline-strontium perovskite mixed concentrate is magnetically removed to remove nepheline, and a concentrate containing 89% to 91% of strontium perovskite is obtained, and the recovery rate is 70% to 75%. The flow is shown in Figure 1.

3. Further recovery of barium perovskite from re- smelting of slime by flotation
Flow of processing (FIG. 2) heavy clay beneficiation by flotation: first sludge in buoyant float apatite, obtained by selection of four-containing P 2 O 5 36% ~ 38 %, 83% recovery ~ 85% of the apatite concentrate. The apatite flotation tailings is further de-sludged, and water glass and collector ИM-50 are added, and the pH of the slurry is adjusted to 5.4-4.8 by H 2 SO 4 to carry out strontium perovskite and nepheline flotation; After the acid treatment of the two kinds of mineral flotation foam, oxalic acid, sodium hexametaphosphate and ИM-50 were used to float the strontium perovskite at pH 6.2-6.4, and the selected strontium-containing calcium-titanium was obtained. 95% of the final concentrate in the mine, the recovery rate of re-selected slime is 82% (about 8% to 10% recovery for raw ore).

Waste Rubber Pyrolysis Machine could process kinds of waste rubbers, 

like rubbers of sliced tyres, rubbers of old shoes, rubbers of waste rubber products etc.

the total power is 11.5kw-17.5kw each whole set machine.

the oil output will be from 40%-90% or even higher if it is pure rubbers.

the main process is that by heating the reactor directly, rubbers will be pyrolysised into oil gas;

condensers or cooling pipes will cool the gas down into liquid oil with the help of recycling water;

then the rest gas which could not be cooled down into liquid oil will be recycled into reactor heating system; after oil gas coming out completely, stop heating the reactor, and cool down reactor below 70 degrees; then can open the door and discharge carbon black automatically...

there are models with capacities from 5tons to 20tons per batch

LN-2200-6000 capacity of 5-6ton 

LN-2200-6600 capacity of 7-8ton 

LN-2200-8000 capacity of 9-10ton 

LN-2600-6600 capacity of 10-12ton 

LN-2600-8000 capacity of 12-14ton 

LN-2800-6000 capacity of 10-12ton 

LN-2800-6600 capacity of 12-14ton 

LN-2800-8000 capacity of 15-20ton 

if cut into smaller pieces, it could process more.
