(2) Equipment Introduction
The inertia cone crusher is a new type of ultra-fine 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 cone swing to crush materials, and there is no rigid connection between the eccentric rotor and the cone, which can well meet the requirements of the new process of "more crushing and less grinding" in the field of crushing, and compared with the eccentric cone crusher, it has a lot of advantages in the use of the process:
1.good The selective crushing effect of the material layer
Because of the crowded feeding, the crushed materials in the crushing cavity to withstand a full range of extrusion, shear and strong pulsating impact, the interaction of particles in the layer, resulting in the mandatory self-crushing of the particles, the product of good particle size.
2. Large crushing ratio, adjustable product size
The crushing force of the machine has nothing to do with the hardness of the crushed material and the filling rate, but depends on the eccentric static torque and rotating speed.
3. Stable technical indexes
The product size is almost independent of liner wear.
4. Convenient operation and installation
Because the whole machine adopts the secondary vibration isolation, the foundation vibration is small, the installation does not need to be ground bolts and huge foundation, 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 non-crushable objects, the moving cone stops moving temporarily, and the vibration exciter will continue to rotate around the axis of the moving cone, which won't damage the transmission system and the host.
6. Simplify the crushing and grinding process, reduce the number of auxiliary equipment
The machine is full of feed, no need for a special feeder, and can be started and stopped at full load.
7. Wide range of applications
Adjusting the working parameters of the crusher, it can crush brittle materials of any hardness.

(4) Main application examples
At present, it has been applied to the crushing of silicon carbide, mullite, quartz sandstone, magnesia, gangue, corundum, granite and other ores. The first grade brown corundum is processed with GYP-300 Inertial Cone Crusher, and when the feed size is -25mm, the granularity of the product is 60% of the granularity of -1.4mm +0.038mm (+140 mesh), making the over-crushing rate, i.e., -0.4mm +0.038mm (+140 mesh). The over-crushing rate, i.e., the yield of -0.106mm (-140 mesh), is effectively controlled below 9%, and the grade particles in the products account for 76.5%; GYP-300 inertia cone crusher is used to replace Raymond mill and tower mill for processing silicon carbide, and all the products are -1.5mm, and the yield of -0.25mm (-60 mesh) accounts for 50.5%, and most of the products are in the form of cubic shape (for details, see the thesis). results chapter).

High square screen (also known as hanging screen) structure is shown in Figure 2-5-1. Sieve body for the left and right two symmetrical sieve box, each box with a partition separated into two bins, each bin put 24 sieve grid, the number of sieve grid can be determined according to the needs of the sieve grid according to the need to screen with a different screen mesh. For example, for graphite grading using 0.3mm (50 mesh), 0.18mm (80 mesh), 0.15mm (100 mesh) three kinds of screen mesh, you can get four specifications of the product at the same time, respectively, from the lower discharge port. The transmission parts make the sieve body make nearly plane circular motion.

Mineral from the upper part of the vibrating feeder into the magnetic yoke and induction roller working gap between the induction roller, under the magnetic force of the induction roller, the magnetic yoke and induction rollers, and the magnetic force of the induction rollers, the induction rollers, the induction rollers, the magnetic force of the magnetic yoke and induction rollers, and the magnetic force of the induction rollers. Under the magnetic force of the induction roller, the paramagnetic minerals are adsorbed on the induction roller, and with the rotation of the induction roller, they are brought into the magnetic product area of the receiving tank, while the non-magnetic minerals enter the non-magnetic product area of the receiving tank under the action of centrifugal force and gravity, so as to complete the separation of the magnetic minerals and the non-magnetic minerals. Unlike the single roll, the non-magnetic minerals after sorting by the upper roll enter the working gap of the lower roll through the receiving chute, and due to the greater magnetic induction intensity of the lower roll than the upper roll, the minerals are sorted again, and the sorting precision is higher and the sorting effect is better than that of the single roll. Flotation-filtering-drying-dry magnetic separation process, so that the Al2O3 content of epsomite minerals from 12.96% to 54.16%, the impurity Fe2O3 content from 4.51% to 1.33%, the product reaches the first-class standard. Among them, the operation index of GCG dry strong magnetic machine is: the Al2O3 content in eclogite minerals is increased from 52.66% to 54.16%, the impurity Fe2O3 content is reduced from 2.47% to 1.33%, and the recovery rate of Al2O3 is 94.01%.
