Sand making machine working principle of material by machine first upper vertical fall within the high-speed rotation of the impeller, Next, in the high-speed action of centrifugal force, with another part of the umbrella form shunt around the impeller material an impact, after which the impeller and the casing, formed between the powerful vortex again or repeatedly hitting each other, friction, crushing. Finally discharged from the discharge opening of the sand making the lower to achieve the required product size is controlled by the screening equipment.
Sand making machine is the professional applications in the production line, to different ore crushing equipment, but in its application, we must pay attention to regular maintenance, then repair What points need it?
a. Sand overhaul, when re-assembled on stage crushing roller clamp coupling, round nut, coupling bolts should be strictly controlled tighten twisting moment shell coupling bolts, screw clasp, yet Note its order, should tighten the bolts to the angle, and then tighten the middle bolt, while paying attention to the coupling points on both sides of the gap should be uniform.
b. Sand maintenance overhaul to open the main sub-transmission gear box lid, re-attach the front rubber seal must be replaced in the static sealing surface evenly coated with a layer of sealant to prevent the sealing surface permeability , oil spills.
c. Sand on the next stage crushing roller bearing translation device link is lubricated with oil, design requirements using a No. 2 or No. 3, calcium-based grease. Each work one week should tighten the oil Lid week grease and normal production.
d. Finally, sand making equipment is widely used in metallurgy, construction, water, electricity, transportation, chemical industry, building materials industry, suitable for crushing hard and above medium hardness ores and rocks.
