NK series mobile crusher is new generation of mobile crushing station equipped with intelligent control system. It makes all components completely airborne, so there is no need to install machine and pour foundation. It can be put into use as soon as it arrives at the production site, which is very flexible.
1.
NK mobile crushing station can be divided into mobile primary jaw crusher, mobile medium crusher and mobile vibrating screen. NK mobile station can be assembled according to the needs of customers, which has stronger applicability and wider application scope.
2.
By changing the main machine to quickly assemble the required mobile crushing station. The investment cost can be reduced and the preparation cycle can be shortened. It can satisfy customers’ diversified needs.
3.
NK mobile crushing station adopts integrated intelligent automatic control system, which is more convenient to operate and more precise to adjust. It is easy to control the whole crushing process.
4.
The main machine equipped on the NK mobile crushing station is specially designed for mobile crusher, which takes advantages of reliable performance, large capacity, high energy utilization and easy maintenance.
5.
Adjustable fixed leg design can achieve no foundation installation. Airborne components do not need to be disassembled, which eliminates on-site installation process. There is no external belt conveyor, and the production site doesn’t need crane and belt conveyor, so mobile crusher can be quickly installed and debugged.
6.
Vibrating screen adopts thin oil self-lubrication mode and it can be replaced lubricating oil once every 8 months, which can save lubricating oil and labor costs.
Working Principle
The PMD New-Generation Permanent-Magnet Direct-Drive Intelligent European Grinding Mill uses a permanent-magnet synchronous motor driving the main shaft directly, removing the reducer and coupling for a shorter, more efficient chain. Versus asynchronous
Requires feed Mohs hardness below 7 and moisture under 6%. Excess hardness accelerates roller and ring wear; too much moisture causes sticking, blockage and lower analyzer efficiency. Pre-dry after crushing to a suitable moisture level.
Qualified fine powder enters the cyclone collector for gas-solid separation and is discharged by a rotary valve; ultrafine fractions are captured again by the pulse collector. Product is pneumatically conveyed to silos or ton-bag packers for automated fi
HPT adopts hydraulic‑driven gear‑rotating adjustment assembly instead of shims. Hydraulic force rotates adjustment sleeve to change gap between mantle and concave so as to modify output size. Real‑time gap value can be read on control system and pa
Daily care includes checking bearing lube and temperature, cleaning or replacing screens, inspecting hammer and liner wear, and checking bolt tightness and rotor balance. As it rotates fast, watch vibration and noise; stock hammers, liners and screens ah
Over‑burning results from excessive residence‑time under high‑temperature zone. Main triggers: excessive fuel input causing combustion‑shaft over‑temperature; over‑long reversing‑cycle prolonging high‑temperature residence; too‑slow discharging‑speed of both shafts; too‑fine feed lumps getting heated too fast; reversing‑valve fault causing flame‑gas offset and local over‑heat. Counter‑measures: cut fuel feed; moderately shorten reversing‑cycle; raise discharging‑rate properly; sieve out ultra‑fine particles; repair reversing‑valve for balanced gas‑distribution to keep over‑burnt ratio ≤5%.
