(2) Brief introduction of equipment

Inertia cone crusher is a new type of superfine crushing equipment with unique principle and structure. It relies on the inertia force generated by the high-speed rotation of the eccentric rotor to make the moving cone swing to crush materials, and there is no rigid connection between the eccentric rotor and the moving cone, which can well meet the requirements of the new technology of "more crushing and less grinding" in the crushing field. Compared with eccentric cone crusher, it has many advantages in use and technology.

1. The selective crushing effect of material layer is good.

Due to crowded feeding, the crushed materials are subjected to all-round extrusion, shearing and strong pulsating impact in the crushing cavity, and the particles in the material layer interact with each other, resulting in forced self-crushing between particles, and the product particles are in good shape.

2. The crushing ratio is large and the product granularity is adjustable.

The crushing force of the machine has nothing to do with the hardness and filling rate of the crushed material, but mainly depends on the eccentric static torque and rotating speed.

3. The technical indicators are stable

The particle size of the product has little to do with the wear of the liner.

4. Convenient operation and installation

Because the whole machine adopts secondary vibration isolation, the foundation vibration is small, and there is no need for anchor bolts and huge foundation during installation, so the working noise is small.

5. Good over-iron performance

Because there is no rigid connection between the moving cone and the transmission mechanism, if the material is mixed with indestructible objects, the moving cone will temporarily stop moving, and the vibration exciter will continue to rotate around the axis of the moving cone without damaging the transmission system and the main engine.

6. Simplify the grinding process and reduce the number of auxiliary equipment.

The machine is full of feed and can be started and stopped at full load without special feeder.

7. Wide application range

By adjusting the working parameters of the crusher, brittle materials with any hardness can be crushed.

(3) Product Series (Table 2- 1- 1)

Table 2- 1- 1 technical parameters of inertia cone crusher

(1) China has not produced.

(4) Main application examples

At present, it has been applied to the crushing of silicon carbide, mullite, timely sandstone, magnesia, coal gangue, corundum, granite and other ores. When the feed granularity is -25mm, the product granularity is-1.4mm+0.038mm (+140 mesh), accounting for 60%. Using GYP-300 inertia cone crusher instead of raymond mill and tower mill to process silicon carbide, the total product is-1.5mm, and -0.25mm(-60 mesh) accounts for 50.5%, and most of the products are cubes (see the paper).

Third, graphite mill

(1) Schematic diagram of equipment (Figure 2-3- 1)

(II) Scope of application of the equipment

It is mainly used for regrinding flake graphite in the final cleaning stage, aiming at protecting large scales and increasing the proportion of large scales in concentrate. It was once used in the graphite mine of Southeast Villa of Yuanshan Mountain.

In order to overcome the direct friction between the upper hammer and the lining plate of the horizontal mill, the vertical mill was used instead of the horizontal mill, which increased the yield of large scales by 1% ~ 2%.

Five, high square screen

(1) Schematic diagram of equipment (Figure 2-5- 1)

(2) Brief introduction of equipment

The structure of rectangular screen (also called hanging screen) is shown in Figure 2-5- 1. The screen body is a symmetrical screen box, and each screen box is divided into two bins by partitions, and 24 screens are placed in each bin. The number of screens can be determined as required, and different screens can be installed on the screens according to the screening needs. For example, when used for graphite classification, four kinds of products can be obtained simultaneously with three kinds of screens, namely, 0.3mm(50 mesh), 0. 18mm(80 mesh) and 0. 15mm( 100 mesh), and discharged from the lower discharge port respectively. The transmission part makes the screen body do circular motion close to the plane.

Figure 2-8-2 Separation Principle Diagram of Single-roller Induction Roller High Intensity Magnetic Separator

Figure 2-8-3 Sorting Principle Diagram of Double-drum Induction Drum High Intensity Magnetic Separator

Minerals are fed into the working gap between the yoke and the induction roller from above by a vibrating feeder. Under the magnetic force of the induction roller, paramagnetic minerals are adsorbed on the induction roller and brought into the magnetic product area of the ore receiving trough with the rotation of the induction roller, while nonmagnetic minerals enter the nonmagnetic product area of the ore receiving trough under the centrifugal force and gravity, thus completing the separation of magnetic minerals and nonmagnetic minerals. Different from the single roller, the non-magnetic minerals separated from the upper roller enter the working gap of the lower roller through the ore receiving groove. Because the magnetic induction intensity of the lower drum is greater than that of the upper drum, the minerals are separated again, and the separation accuracy is higher and the separation effect is better than that of the single drum.
