Slag miner

In the instrial "beating and washing process"

1. pulverizing, one ore is put into the pulverizer, which consumes EU and time, and turns into two crushed ores, increasing proction by two times as much as the original one, Some small pieces of powder (9 small pieces of powder, a powder, a furnace to burn powder into an ingot), and a stone powder (which can be used as building foam)

2. centrifugation, and put 1 pure crushed ores into the heat centrifuge (must give the centrifuge red stone signal, or it will consume a lot of time). It still consumes EU and time, and becomes a powder, a handful of powder (except uranium mine). It will become uranium 238 and 235)

Crushing equipment is the mechanical equipment used to crush minerals
crushing operations are usually divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging particles. The commonly used sand and stone equipment include jaw crusher, impact crusher, impact crusher, compound crusher, single stage hammer crusher, vertical crusher, rotary crusher, cone crusher, roller crusher, double roller crusher, two in one crusher, one-time molding crusher, etc
it can be divided into six categories according to crushing mode and mechanical structure characteristics (action principle)
(1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block sandwiched in it< (2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block
(3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly crushed continuously, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher
(5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6) other types of crushers and grinders. Drilling machinery is divided into rock drill and drilling rig, and drilling rig is divided into open-pit drilling rig and underground drilling rig

② surface drilling rig: according to the working mechanism of crushing ore and rock, it can be divided into wire rope percussion drilling rig, down the hole drilling rig, cone drilling rig and rotary drilling rig. Because of the low efficiency, the wire rope percussion drill has been graally replaced by other drills
③ downhole drilling machine: when drilling borehole with diameter less than 150 mm, in addition to rock drill, 80-150 mm small diameter down the hole drill can also be used. Using the axial pressure and rotary force of the cutter to roll the rock surface, it is a mechanical equipment for directly crushing ore and rock.

1. Working principle of overflow ball mill

3. Working principle of horizontal ball mill

the appearance of horizontal ball mill is a horizontal cylindrical rotating device, which is driven by outer gear, sprocket or belt. Different from lattice and overflow ball mill, it has two material silos. When the ball mill cylinder starts to rotate, the material is loaded into the cylinder by the hollow shaft at the feed end of the ball mill. Due to the combined action of inertia, centrifugal force and friction, the material parabolic operation is realized and the grinding is completed

the grinding principle diagram of ball mill is derived from the fact that the network materials enter the first bin of the mill evenly through the feeding device feeding hollow shaft screw, in which there are stepped lining plates or corrugated lining plates, with different specifications of steel balls built in. The centrifugal force generated by the rotation of the cylinder will bring the copper ball to a certain height and then drop, which will have a heavy impact and grinding effect on the materials. After coarse grinding in the first bin, the materials enter the second bin through the single-layer partition board. There is a flat lining plate and steel ball in the bin. The materials are further ground, and the materials with finished proct particle size are discharged from the discharge end of the cylinder to complete the powder operation

5. Working principle of planetary ball mill

planetary ball mill is equipped with four ball milling tanks on the same rotary table. When the rotary table rotates, the ball milling tanks will rotate around the rotary table, and at the same time, they will rotate around their own axis, making a star like motion, while the grinding balls in the tank collide with each other in high-speed motion, grinding and mixing materials
