The gravity dust removal of the heavy hammer crusher can process coarse particles above 100 UM for pretreatment of coarse dust and other fine dust. The operation method is to introduce dust-containing gas into a large-volume gravity sedimentation tank, reduce the gas flow rate, and use gravity to precipitate particles and separate the gas; electric dust can remove solid particles in the gas and be attracted to the oppositely charged electrodes. To achieve the purpose of dust removal.

The electrostatic precipitator adds tens of thousands of volts of DC voltage between the metal discharge electrodes, causing the gas between the two electrodes to ionize. When the negatively ionized gas collides with the solid particles, the solid particles are also negatively charged, attracted by the positive electrode, neutralized and charged, and then settled. come down. This method is suitable for fine dust removal with higher requirements; however, the dust concentration should not be too high and the gas flow rate should not be too fast.

The scrubbing and dedusting make the gas contact with spray water to capture the solid particles in it. The commonly used spray dust removal tower introduces gas from the lower part, and the water is sprayed from the upper part into a mist for countercurrent washing; centrifugal dust removal uses the centrifugal force generated by the rotation of the gas to be hundreds to thousands of times larger than the gravity of the particles, making the solid particles solid Particles. The equipment is fixed along the peripheral wall. The equipment used is a cyclone dust collector. The inlet speed is usually 10-20M/S, and the small particle size that the hammer crusher can capture is 5MU or less. Inertial dust removal can be used to separate particles and gases above 5 UM. During the orientation of the baffle, the dust-laden gas hits the baffle of the inertial precipitator, and due to inertia, particles are captured. In order to prevent the scattering effect during the impact collision, a high flow rate cannot be used.

As we all know, high manganese steel has the characteristics of work hardening. However, the force of the high manganese steel hammer of the heavy hammer crusher in the actual working process is mostly low and medium stress, and the impact resistance of the crusher accessory hammer is not enough, so that the surface of the hammer cannot be quickly hardened. After the cone crusher is high The wear resistance of the manganese steel hammer is poor, and the high manganese steel hammer is gradually eliminated.

Jaw crusher has better toughness to prevent brittle peeling or cracking

During use, the slab is subject to friction from the material, or cutting wear of the components. Therefore, the required material has high hardness to resist plastic fatigue and cutting wear, and has better toughness to prevent brittle spalling or cracking. When actually choosing the material of the seesaw, it is necessary to fully understand the working conditions and wear mechanism, and choose the material of the seesaw reasonably. The following are four suggestions for choosing a jaw crusher.

1. The carrying capacity of the seesaw. The larger the size of the jaw crusher, the greater the obstruction of the crushed material and the greater the impact load on the jaw. At this time, when selecting materials, the impact of the seesaw should be considered first. If it is small, uneven plastic deformation will occur, which will cause vibration and noise when the equipment is running.

2. The hardness of the material. The machine crushes different materials such as granite, quartz cliffs and limestone. The material of the slab is different. The higher the hardness of the material, the higher the hardness of the corresponding slab.

3. The toughness of the material. The moving plate and the fixed plate are different from the wear mechanism, and the moving plate receives a great impact. Therefore, toughness should be considered first; and the fixed plate is supported by the frame, so hardness can be given priority.

4. Economical and practical. When choosing the materials for the seesaw, technical and economic effects should also be considered, and strive to achieve high quality, low prices, and market competitiveness. At the same time, the rationality of the process should also be considered. It enables production plants to easily organize the quality of production control.

When lubricating the jaw crusher, it should be determined according to the place of use, temperature and other conditions. In winter, if the dry oil is solidified, you can add 20:6 (weight) car oil. Oil; According to the operation and usage, the oil can be replenished every 1-2 days, and the lubricating oil can be changed every quarter. Lubricate the surface of the mocha in time, such as the contact between the bracket and the foot pad. Before starting the machine, grease must be added.
