NK series mobile crusher

For construction waste with mixed steel bars and iron fragments, magnetic iron separator is standard or optional, suspended above main discharge conveyor belt. It attracts steel bars and nails during material conveying and reduces impact damage risk to main crusher. Adjust separator height on‑site for optimal magnetic capture. Some heavy thick steel may escape separation, requiring manual pre‑sorting. Regularly clean accumulated iron scraps on magnet to prevent falling‑back into material stream.

Besides main NK unit, select auxiliary options including magnetic iron separator, site grounding cables, buffer liners, spare screen meshes and conveyor belts. Diesel generator set is optional for off‑grid sites. Prepare steel base plates for soft ground conditions on‑site. Equip tool kit, initial fill of hydraulic oil and lubricants. Prepare wear‑part stock according to ore hardness and relocation frequency to sustain continuous production and reduce downtime waiting for spare‑part delivery.

NK plant belongs to semi‑trailer‑type equipment, transported by trailer as whole or split modules. Check overall dimension and axle load to comply with national over‑limit highway regulations. Some over‑width/over‑height modules require disassembly of main crusher, guardrails and chutes. Hardened highways are preferred; long‑distance cross‑country driving is forbidden. Lock conveyor arms and hoppers before towing. Cross‑region transportation may need over‑limit permits. Reassemble and commission after arriving at job‑site before production.

NK wheel‑type advantages include lower capital cost, efficient highway towing and simple maintenance for sites with paved roads and frequent relocation. Drawbacks are poor performance on muddy rough terrain; it cannot move by itself and depends on external trailer. On‑site levelling takes extra time. Tracked units travel off‑road independently yet cost more for purchase and maintenance and require flat‑bed truck for highway haulage. NK fits urban solid‑waste and suburban quarries; tracked plants are preferred for mountain sites without access roads.

If actual output is lower than catalogue value, check whether feed lump size exceeds limit or high‑moisture clay causes clogging. Inspect leg leveling condition and material loss from misaligned conveyors or screens. Verify continuous stable feeding and avoid frequent starved‑feed. Under‑powered diesel generator also restricts capacity. Frequent disassembly and relocation may loosen transmission and locking components and degrade efficiency. Troubleshoot process conditions and machine status instead of directly referencing ideal catalogue lab‑data.

NK wheel‑mounted plant flexibly equips C6X jaw crusher, HPT cone crusher, impact crusher or sand maker for different process units. Jaw‑crusher unit performs primary crushing for lump ore and construction waste. Cone or impact‑crusher units deliver secondary crushing for manufactured aggregates. Mobile screening unit realizes material classification and closed‑circuit re‑crushing. Sand‑making unit produces finished manufactured sand. Multiple NK units can work in line to complete full production flow according to raw‑material features and product requirements.
