Mine crusher dust catcher design in ore dressing production in crushing screening, loading and unloading transportation, dry grinding powder dry separation process, etc, the number accounts for about 0.5% of the ore processing ~ 1.05, the initial concentration of 2 ~ 5 g/m3, dust of true density of about 4 t/m3, particle size is greater than 20 microns accounted for 60% ~ 80%. Mineral dust comprehensive dust control measures should be taken to, basically have airtight, wet dust prevention and dust source mechanical dust removal.
   Mine material crushing system dust collector of raw ore, ore and raw materials such as limestone, dolomite, bauxite, coal crusher or mill feeding port and discharging port, the upper vibrating screen and belt conveyor airtight device is installed in areas such as the transshipment point or dust cover, transshipment point where appropriate set double sealed cover. Producing dust equipment in sealed envelope, or making small dust collecting room, uniform enclosure forming negative pressure and avoid dust to escape, or by exposure to form suction trap air suction hood, will be exposed to dust area control in narrow range, with dust air suction trap siphoned off, and after purification by bag filter through the vent (or stack) discharged into the atmosphere.
Mine crusher dust collector structure features:
A, the ladder type flat bag in cylinder body decorate, simple and compact layout, filter area index is high. Under the effect of the blowing, trapezoidal flat bag of large amplitude, a single jar, can shake off the dust, to improve life of filter bag.
B, in addition to the cold region, the filter can be open Settings.
C, shell, is designed according to the type cyclone volute import can partial whirlwind role, reducing load filter bag. Size of the barrel vaults and uniform stress, antiknock performance is good.
Resistance of d, with a filter that serve as signals, but automatic control of rotary counter blowing ash removal, depending on the inlet concentration of high and low, automatically adjust the soot cleaning cycle.
E, this equipment is divided into blocks, on the cover can be open, in bag, maintenance is very convenient.
F, this equipment after several design, inlet concentration without limited to 15 g/m3. Even if don't have to increase the cyclone 150 g/m3. This equipment has the function of the cyclone, but there is no the resistance of the cyclone. Increase cost cost, cost is this equipment will not improve.
G, the equipment of form a complete set of high pressure fan blow soot cleaning, use occasion of air condition limit, less wearing parts, maintenance of portable, reliable operation, overcome the disadvantages of compressed air pulse ash removal, reverse blowing big range, can be used long filter bag, full use of space, cover an area of an area small.
