Jaw crusher dust detailed description of methods

Article source：

Jaw crusher dust dust particles is based on characteristics such as particle size , density , concentration, adhesion, moisture and electrostatic characteristics , the application of appropriate methods for dust removal work . The following is a jaw crusher dust removal method in detail.

First, the gravity dust: can handle more than 100μm coarse particles , for coarse dust and other fine dust pretreatment . Mode of operation is the large volume of gas into the dust gravitational settling tank , reduce the gas flow , generated by gravity settling the particles and separated from the gas .

Second, the centrifugal dust : the use of gas generated when the rotational motion of gravity than large particles suffered several hundred to several thousand times the centrifugal force , Impact Crusher the solid particles along the peripheral wall of the settlement, the equipment used for the cyclone , usually inlet velocity at 10 ~ 20m / s, to trap the smallest particle diameter of 5μm or smaller .

Third, the inertial dust: for particles larger than 5μm and gas separation . Dusty gas stream in the directional fold impact on the bezel in the inertial dust particles due to inertia and captured , in order to prevent the scattering effect of the impact of a collision , not using high flow rates.

Fourth, scrubbers : contacting the gas with the spray water to the solid particles trapped therein . Jaw crusher dust spray tower is used to import gas from the lower part of the water from the upper spray form , countercurrent scrubbers .

V. ESP : the solid particles in the gas bring the charge , so as to be attracted to the electrode of opposite charge to achieve the purpose of dust . ESP applied between the metal discharge electrodes a DC voltage of tens of volts , caused by ionized gas between two poles , negative ionization of gas and solid particles collide , the solid particles are negatively charged , attracted by the positive electrode , and in charge after the settlement down . Hongxing Heavy Industry that the law applies to the high requirements of the fine dust ; but dust concentration is not too high , the gas flow rate is not too fast.
