1T/H Cattle Feed Grinder Machine in Malaysia

Dry Napier Is the Material Specification

The main material is dried Napier stalks and leaves, with a starting grinding moisture specification of 12–15% on a wet basis. Harvest age matters: older stems are generally more fibrous and lignified, so their grinding behaviour and feeding value differ from younger material. Moisture and stem content are recorded for each delivery.

• Fresh-cut Napier requires a forage chopper followed by suitable drying before this dry hammer-milling stage.
• Dry baled Napier requires opening, removal of twine and foreign material, then pre-chopping.
• Clean, already chopped dry forage can enter the metered feeding stage after moisture and size checks.

The pre-chopping target is approximately 20–40 mm, avoiding long strands that can bridge above the grinding chamber. Material wet from rain is held for moisture correction. Feedstock with mould or spoilage is rejected rather than treated as a grinding problem.

SFSP66×60 Specifications for the Forage Duty

The 55 kW configuration has a published grass-and-straw capacity reference of 1,000–1,500 kg/h. For this Napier application, the planning range is 1,000–1,200 kg/h, subject to trials at the required moisture and particle size. Grain output figures are not used to size the forage duty.

This configuration gives the grass crusher machine a defined starting point without purchasing a larger grinding station before testing its own forage. The final screen and hammer arrangement must produce acceptable meal at a stable motor load. Changing to a smaller screen can reduce throughput and increase energy demand.

Check the Ground Meal with Sieves

A 6 mm screen aperture does not mean every discharged particle measures 6 mm. Hammer impacts produce a distribution of sizes, and elongated fibres may pass through openings differently from compact grain fragments. The 2–3 mm mean-size target therefore needs an agreed sieve-analysis procedure, together with inspection of the longer fibre fraction.

The grinder produces a feed ingredient. In this application, the existing mixer combines Napier meal with prepared maize meal, palm kernel expeller, rice bran and the specified supplements. Each ingredient follows its own preparation route; purchased fine meals do not automatically need another pass through the forage grinder.

The downstream pellet specification for the example is 8 mm diameter with a target length of 10–20 mm, controlled by the existing pellet mill’s die and cutter. These pellets are intended for use within a balanced cattle feeding programme. Fine grinding and pelleting do not remove the need to assess physically effective fibre in the complete ration or provide suitable longer forage.

The Mixer Schedule Sets the Grinding Target

A planning recipe using 300 kg of Napier meal in a 1,000 kg mixing batch illustrates the connection. At 1,000 kg/h, one hour of forage grinding supplies slightly more than three such batches. The nutritionist determines the actual inclusion rate; this example checks equipment flow rather than prescribing a diet.

Four productive grinding hours on 250 operating days would process 1,000 tonnes of prepared forage annually at that calculation point. This is grinder throughput before handling losses, separate from total compound-feed output. Cleaning, screen changes and maintenance sit outside those productive hours.

A covered intermediate bin allows the grinder and mixer to run on different schedules. Its capacity follows the batch plan and measured meal bulk density. A small, frequently replenished stock is preferable where humid conditions make extended storage difficult.

Keep Material Moving Through the Grinding Stage

Dry grass is bulky, so feeder capacity must be checked by volume as well as weight. Controlled feeding limits sudden loads when dense stem bundles enter the chamber. The operator watches motor current, discharge flow and screen condition, reducing feed when the material becomes harder to process.

Aspiration and dust collection are part of the grinding assessment. The fan duty depends on the mill arrangement, ducts, separator and filter resistance. An existing fan is retained only after its performance is checked. A restricted filter or poorly arranged discharge can limit production even when the main motor has spare capacity.

Trial records should include weighed throughput, moisture, sieve results, electrical consumption and interruptions. Comparable runs on representative forage establish whether the replacement can keep the meal bin supplied. Any claim of lower energy use requires measurements under equivalent grinding conditions.

Fit the Replacement to the Johor Workshop

The installation review checks foundation loads, feeder and discharge heights, duct connections and access for screen and hammer replacement. Existing floor space is assessed from the equipment drawing. Staffing provision allows one grinding operator with shared help for bale opening and loading.

Electrical selection uses Malaysia’s nominal 400 V, 50 Hz three-phase supply as a design basis, with actual site conditions and motor starting capacity confirmed before manufacture. The 55 kW main drive is not the installed power of the whole grinding station. Feeder, aspiration and conveying loads are added separately.

Shipment planning starts at Qingdao. For a Johor destination, a quotation can compare arrival through Tanjung Pelepas with Port Klang and the respective inland haulage. Carrier availability, packing dimensions and delivered cost determine the selected route.

For a cattle feed grinder machine in Malaysia, a useful enquiry starts with photographs of the delivered forage and a recent moisture result. Add the incoming length, required ground size, tonnes needed per shift, current mixer schedule and existing extraction details. RICHI Machinery can use this information to define a Napier grinding trial and quote the machine with its required connections.
