Application field
Composite crusher is mainly used for metallurgy, mine, chemical, cement, architecture, refractory materials and ceramic industrial departments second and third -level crushing of hard ore and rocks. -1000mm, the average production particle size ≤ 5-8mm.
Composite crusher prospect
Faced with the peak period of China's high -speed railway construction, the market demand for the composite crusher is particularly strong. However, due to the construction of high -speed railways, the requirements for sand and gravel aggregate and concrete aggregate are relatively high, and large enterprises with this production capacity in the composite crusher industry that meet the demand are at least ten. The composite crusher has been widely installed in the construction of highways and high -speed railways in various provinces and cities across the country. It is an indispensable equipment for national infrastructure construction. For the broken stones that have been broken by composite crusher, after the shock crushing neat particles, the stone needle can be reduced to about 4%. equipment.
Maintenance
The composite crusher is used to crush iron ore, sandstone, gypsum, high scum, coal gangs, and coal. Long -term use will inevitably be covered with dust. , Resulting in the shortened service life of the composite crusher. Today, teach you how to effectively remove the dust inside the composite crusher.
1. The bag dust collectors at the corner of the composite crusher and the corner of the belt machine are updated to the LNGM64-4 and the LNGM4-8 bag dust collector. Its technical performance parameters are shown in Table 2. According to the characteristics of dust, water -resistant oil -proof filter materials are used. LNGM4-8 bag dust collector is open-air, and the shell is insulated and waterproof. In order to ensure the reliable operation of the equipment, the brand and specification model should be paid attention to when purchasing the key accessories of the bag dust collector to reduce the fault rate of the equipment.
2. Improve the process layout of the bag dust collector, and arrange the dust collector of the composite crusher according to the direction of the belt machine; transform the standard ash bucket of the bag dust collector into a pair of ash bucket structure, so that a spiral conveyor is canceled, and Lift the bag dust collector, which is conducive to the layout of the air duct (the angle of the duct is large); set the inlet of the air inlet to make the dust in the composite crusher directly enter the inlet box of the dust collector, saving the elbow, which saves the elbow, which saves the elbow, which saves the elbow, which saves the elbow. , Reduce system resistance and improve dust collection efficiency. Its process layout. The gray bucket lock wind uses a single -layer overturn valve, which cancels the grid wheels and its motor to reduce the dust and improve the dust removal effect.
3. The dust at the corner of the belt machine is restricted by on -site conditions. The slot and the dust cover cannot be changed. The deployment process is decorated in Figure 4 to make the dust cover in a slightly negative pressure to eliminate the dust of the belt machine.
4. Based on the service life of the filter and pulse valve, and the dust of the ash into the ash, in order to improve the comprehensive dust removal effect of the composite crusher and the belt machine, when crushing the dry material, it can be as needed as required as required. Perrace the water at the entrance of the composite crusher (it is required to be performed after the composite crusher 10 ~ 20min).
5. Strengthen the management of dust removal equipment, check the closed conditions of the dust cover on a regular basis, and discover problems in time. Implement the implementation target management assessment of the dust discharge of the job environment and bag dust collector, regularly monitor dust monitoring, use economic leverage to mobilize the work enthusiasm of the staff, improve the level of maintenance of dust removal equipment, and minimize dust pollution.
