9HLSJ-20 Total Mixed Ration Feed Preparation Machine

Maintenance of Vertical Total Mixed Ration Feed Preparation Machines

I. Reducer Maintenance:

For the new machine, replace the reducer lubricant every 3 months; thereafter, replace the reducer oil annually. Each reducer uses 24 kilograms of L-AN46 total-loss system oil.

II. Inspect the blade:

Check the wear condition of the moving blades on the tower core. If the blades are dull, immediately sharpen or replace them.

3. Bearing Lubrication:

The spindle bearing housing needs to be lubricated with grease once every two weeks. Note: The bearing oil passages are very narrow. If the bearings aren't lubricated for an extended period, the oil in the passages will dry up, making it impossible to inject more lubricant later on.

IV. Hydraulic System Maintenance:

Regularly check whether the oil pipe fittings and fasteners are loose to prevent leaks and detachment. Replace approximately 6 liters of L-HV46 low-temperature anti-wear hydraulic oil annually. (In winter, ordinary hydraulic oil tends to freeze, and if the hydraulic oil freezes, the hydraulic pump will fail to operate.)

V. Special Attention:

Before starting work, briefly activate the switch and check whether the tower core’s rotation direction matches the indicated direction. If the rotation direction does not match the indication, reverse the connection sequence of the main power supply cables. Then, run the feed mixer at no load for 2–3 minutes to ensure that all equipment functions properly before beginning the feeding process. (If the rotation direction is reversed, the tower core may become jammed, potentially damaging the tower core blades or the gearbox. Pay special attention: after a power outage and before restarting the machine, be sure to confirm that the rotation direction is correct before adding feed.) Each shift, check that the gearbox oil reservoir for the tower core contains at least half a tank of oil; insufficient oil in the reservoir could lead to damage of the gearbox.
