Change the screenHydraulic System1 Hydraulic system function1.1 Open the rotor upper cover to inspect, repair and replace the hammer.1.2 Overturn the rotor cover to inspect, repair and replace the screen.1.3 Pressure regulationWhen need to increase pressure, open the cut-off valve, start-up oil pump supplies oil for the oil cylinder, when pressure reaches required valve, turn off the cut-off valve. When need to reduce pressure, open the cut-off valve, change the oil pump switch to oil return position, oil cylinder pressure can be reduced.2 Function of accumulatora. Accumulator play the role of energy storage and reducing impact. When machine is on work, stop valve should be in off state. When the swing arm rises, accumulator will release oil into oil cylinder; When the swing arm falls, oil in the oil cylinder flows back to the accumulator. The leather bag of accumulator has a certain nitrogen pressure, so when oil inflows and outflows, nitrogen will have buffer effect and make the swing arm move smoothly without impact.b. Accumulator can be disassembled only under the condition of the oil pressure runs out.c.Adjust the upper feeding roller weightWeights of upper feeding roller shall be adjusted according to different feeding materials. When handling large-sized material, weights of up feeding roller will be higher. When handling small-sized material, such as slab and waste slab, weights of up feeding roller will be lower.3 Maintenance RequirementsThe set pressure of hydraulic system is 16MPa. Do not change it casually. Hydraulic oil is 46# anti-wear hydraulic oil. When temperature exceeds 40oC, suggest use 68# anti-wear hydraulic oil. In order to ensure hydraulic system works normally, please check it, clean the oil filter and air filter twice a month, also check whether the bolt of oil pump inlet and outlet is loose, whether O-type ring is damaged twice a month. Replace the O-type ring in time. Replace hydraulic oil once in three months. Inspect oil cylinder once a year to check whether oil cylinder leaks, whether sealing ring is damaged and replace it in time.Sealing ring size for the system is 18 type compound gasket ( for oil cylinder), φ12×2.4 O-type ring andφ22×2.4 O-type ring.Electric Control1 Main motor protection1.1 Main motor starts by soft start switch. There is overload protection device in circuit, which can shutdown circuit if overload.1.2 When the main motor current exceeds rated value, and sustained a period of time, user should stop feeding, reverse feeding system, debug after materials drop out, start the feeding system, and then continue to feed.1.3 Main motor shall not start continuously and frequently.2 Reverse operation of feeding motorWhen feeding motor needs to be inverted, must press the Machine Stop button first, then press Reverse button after feeding system stops. The process can also be realized by equipped wireless remoter.3 Operation of oil pump rise and fallWhen material is jammed in the feed inlet and can not feed any more, press the Hydraulic Lift button, raise the upper feeding roller, loose the Hydraulic Lift button, upper feeding roller will fall by gravity function. 4 Operation of breakdown resetWhen frequency converter breaks down, Alarm indicator lights up. When breakdown is solved, press the Reset button, then frequency converter works normally.5 Emergency stop operatingPress the Emergency button when the following situation arises:- when there is iron block, stone etc such kind of foreign material enter the machine-when there is abnormal noise, vibration which can not find the resource or solve in time.-other emergency when can not shut down one by one.After pressing the emergency button, all the motors will power failure and stop working. When resuming working, must switch the Emergency button to normal position. 6 Control cabinetThe control buttons are all installed on the electric control cabinet. Control buttons include Machine Start, Machine Stop, Feed In Start, Feed In Stop, Reverse, Discharge Start, Discharge Stop, Oil Pump Start, Reset, Emergency. Indicating instruments include voltage meter, ampere meter. Indicator lights include: Main Machine, Feed In, Reverse, Discharge, Oil Pump, Alarm. 7 How to use remoter?After supplying power, press the Oil Pump Start button on the control cabinet, afterwards press the Start Button on the remoter, then remoter starts working. Remoter only control feeding. Remoter will not work after pressing the Emergency button on the control cabinet.8 How to change the feeding speed? Change the HZ of feeding conveyor can change the feeding speed. High speed produces large output, low speed produces small output. Do not change them unless really necessary. The two HZ must be the same numberProduct Features1) Rotor rotation speed adjustable. According to the customer's specific requirements, the machine can be modified, such as adjusting the corresponding parts to change the rotation speed of the rotor, to meet the different requirements of customers on discharging granularity and production capacity.2) Unique dead knife design. Thanks to the decades of experience, we create a special shock absorbing buffering dead knife design and already got the patent. This design protects the rotor, decreased the maintenance cost and extends the life span of the machine.3) Forced auto feeding system. Start the oil pump, oil cylinder piston extend-retract, swing device rises or falls, then the upper feed roller adapt to the nature of feedstock automatically. This function enables the machine can adapt to wide range raw material and the feed process is more smooth. We got the patent for it.4) Easy maintenance. Thanks to the hydraulic system, it is easy and convenient to open the machine cover to check or replace the cutter, screen mesh and so on.5) Chain conveyor. The feeding chain conveyor is made of high manganese steel with the thickness 10mm, which is a typical anti-wear steel, cast organization is austenite and carbide. Via the water toughening treatment, the surface would be rapidly hardening and that make its internal remains the good toughness and deformability under the condition of strong impact and extrusion and the hardening layer with good wear resistance. These characteristics determine that the service life can be up to 22000 hours, which is better than the traditional belt's 2000 hours. In addition, the traditional belt' s with small friction coefficient which will cause the feed speed to be slow and not smooth, but the chain type solved all the above questions.6) Perfect chain conveyor length. The length of the chain conveyor is matched with the machine running, which can achieve the best machine performance.7) Dual control, One is fixed electrical cabinet and the other is remote control, that makes the operation more safe and convenient.8) Automatically frequency conversion contorl for feeding system. Feed roller and chain conveyor can be adjusted automatically by the frequency conversion that makes the operation is safe and simple. According to the specification and quantity of raw materials, the feeding speed can be adjusted automatically to save energy and promote efficiency. It can adjust feed speed automatically according to the load of main motor to avoid idle running of machine.9) Overload protection.The main motor starts by a soft start switch, and the circuit has an overload protection device, which automatically cuts off the circuit when overloaded.10) Interlocking control of feed system and avoid feeding plugging. During normal operation, feeding motors and chain conveyor motor work simultaneously. Once there is a plugging, feed system stop feeding, two feeding motors and chain conveyor reverse together.When feeding too much material, the main motor current increases, the frequency of frequency converter will decrease, rotation speed of two feeding motors will slow down, feeding volume will decrease. When main motor current decreases to a certain value, the frequency of frequency converter wil increase, two feeding motors rotation speed will speed up, feed rate will increase.This control process is realized by equipped wireless remote control.11) Pulley secured by inner hole locking device. Easy to assemble and disassemble. No the traditional violent assemble and disassemble. Protect the main motor. This makes easy to maintain the main and prolong the life span of the main motor.Product ParametersModelHX1400-800HX1600-600HX1600-800HX2000-1000Rotor diameter (mm)110080011001400Cutter quantity (piece)8 or 288 or 308 or 366 or 42Input size (mm)1400-8001600-6001600-8002000-1000Rotor rotation speed (rpm)900760900432Max material diameter (mm)400300400500Production capacity (tph)25-3025-3035-4050-70Main motor power (kw)250250315400Chain feed conveyor length (m)6668Discharge conveyor length(m)10101010Weight (t)26232752Dimension (m)10x2.62x3.4m 10.5x2.64x311.03x2.85x3.413.8x3.28x3.9ModelHX1260-500HX1400-500Rotor diameter (mm)800800Cutter quantity (piece)8 or 248 or 28Input size (mm)1250-5001400-500Rotor rotation speed (rpm)650760Max material diameter (mm)300300Production capacity (tph)12-1515-20Main motor power (kw)160200Chain feed conveyor length (m)55Discharge conveyor length(m)1010Weight (t)1416Dimension (m)8.1 x 2.2 x 2.68.5 x 2.5 x 2.7 Manufacturing processCompany ProfileShandong Hongxin Machinery Co., LtdOur company is a professional manufacturer of log debarker, wood chipper, horizontal grinder, tub grinder, hammer mill and wood pellet mill.Our company has introduced a series of advanced equipment including CNC Lathe, CNC Milling machine, Planer, Drilling machine, Sawing machine, CNC Boring machine, Balancing machine, Coiling machine.
