Four-sieve block (gravel, sand, dust, blackstone)¶

Water first. Each Stone Barrel drinks 1 B per block, so 4 cobble barrels need 320 B per minute (about 270 mB/t). One Aqueous Accumulator keeps two barrels busy (your current line), so use 4, or fewer with an LV Upgrade Kit inside. Run Pipez fluid pipes to every barrel. — thermal:device_water_gen, pipez:fluid_pipe
4 Stone Barrels with a lava bucket inside (kept) and ghost circuit 0: 4 × 80 = 320 cobble per minute. The block needs 288 (96 for each of the gravel, sand and dust sieves). — gtceu:stone_barrel, minecraft:lava_bucket
Witch water: a Large Barrel with mycelium spores in its input bus (kept) turns 1 B of water into 1 B of witch water every 4 s, 15 B per minute. — gtceu:large_barrel, exnihilosequentia:mycelium_spores
2 more Stone Barrels with lava kept and witch water piped in make blackstone (1 B witch water each). They are only as fast as the witch water: 2 Large Barrels give 30 blackstone per minute; 7 would feed the sieve at full speed (96). — gtceu:stone_barrel, minecraft:blackstone
3 Forge Hammers turn cobble into gravel (0.5 s and 16 EU/t each, 120 per minute per hammer, 360 total for the 288 needed). Barrels auto-output into a drawer; Pipez item pipes in round-robin feed the hammers. — gtceu:lv_forge_hammer
The gravel drawer splits: one third to the gravel sieve, two thirds to 2 more hammers (gravel to sand, 192 per minute). The sand drawer splits half to the sand sieve, half to 1 hammer (sand to dust, 96 per minute). — minecraft:gravel, functionalstorage:oak_1
The 7th hammer crushes blackstone into crushed blackstone for the fourth sieve. — exnihilosequentia:crushed_blackstone
4 Mechanical Sieves, each with a string mesh in its input bus (never used up). Every 40 s at 30 EU/t: gravel gives 16 copper, iron, tin, sphalerite and magnetite; sand 16 quartz, diamond, lapis, amethyst and emerald; dust 16 redstone and glowstone, 4 sulfur and 4 ender pearls; crushed blackstone 16 galena and 16 stibnite. — gtceu:mechanical_sieve, exnihilosequentia:string_mesh
Power from its own diamonds: a pipe with a filter sends diamonds from the sand sieve into a Lapidary Dynamo with an LV Upgrade Kit (200 × 6 = 1 200 RF/t = 300 EU/t). One diamond is 300 000 RF here, so the block burns about 3.4 of the 24 diamonds it makes per minute. — thermal:dynamo_lapidary, kubejs:lv_upgrade_kit, minecraft:diamond
2 LV 4A Energy Converters (128 EU/t each, 256 total) turn the FE into EU; soul infused wire runs to the 7 hammers and 4 sieves. Peak draw is 4 × 30 + 7 × 16 = 232 EU/t. — gtceu:lv_4a_energy_converter, gtceu:soul_infused_quadruple_wire
No Lapidary Dynamo yet? Use the Create steam option instead: 3 Steam Engines + 4 Generator Coils give about 307 EU/t for roughly 2 charcoal per minute (see "Create steam power"). — create:steam_engine, create_new_age:generator_coil
Bootstrap: the dynamo needs its first diamond. Put a few in by hand, or run the sand sieve once from any other power. — minecraft:diamond

Tips¶

Every sieve eats 64 blocks per 40 s = 96 per minute. Amounts shown are per 40 s batch.
The whole block draws about 210 EU/t (232 at peak). Before you have a Lapidary Dynamo, power it with Steam Engines + Generator Coils (see the power options).
Witch water is the slow part: full speed on the blackstone sieve needs 96 B per minute (7 Large Barrels). Two barrels run it about a third of the time.
