Custom Hammer Mill Feed Grinder Manufacturers

Goldlong Machinery and Engineering Co., Ltd. is a China-based manufacturer and supplier of feed grinding systems, with hammer mills engineered for poultry, livestock, aquatic and premix feed production. Our SFSP and wide-type pulverizer range covers capacities from roughly 1.5 t/h to 45 t/h, so the same family can serve a small premix plant or a large integrated feed mill.

We combine a teardrop-shaped grinding chamber, dynamically balanced rotor and adjustable hammer-to-screen clearance into machines that handle both coarse and fine grinding in one production line. As a Custom Hammer Mill Feed Grinder Manufacturer, we do not stop at the mill itself — we supply the magnetic feeder, air duct, support frame, electrical cabinet and full commissioning support needed for a working grinding station.

Each series has a specific position in the feed production flow, from pre-grinding bulky ingredients to fine pulverizing for aqua feed.

Selection starts with the raw materials you grind. Corn, wheat, soybean meal, rapeseed meal, rice hulls and fish meal differ in density, moisture and fibre content, and each affects feeding rate, screen life and motor demand.

Our mills suit typical feed mill moisture levels without pre-drying. For dusty ingredients, we recommend a pre-cleaner and magnetic separator before the mill to protect hammers and screens. A variable-frequency feeder prevents surging when material bulk density varies.

• Required throughput in tons per hour at a defined screen hole size, e.g. 2 mm, 3 mm or 1.5 mm aqua feed spec.
• Available motor power and local voltage/frequency (380 V/50 Hz, 440 V/60 Hz or other grid standard).
• Desired particle size distribution and whether the mill is used for coarse broiler feed, fine aqua mash or regrinding.
• Feeding method: manual, bucket elevator, screw conveyor or upstream magnet a nd variable frequency feeder.
• Dust control requirement and connection to a pulse filter or central aspiration.

Our proposal states output range, installed power, machine weight, external dimensions, recommended aspiration and feeder options. We do not certify an output number without knowing the material and screen specification.

Our hammer mills integrate with the feed plant's electrical control system. For automated lines, we supply frequency conversion control for the feeder, interlock with upstream conveyors, overload protection, bearing temperature measurement and vibration monitoring outputs that can be read in the control room.

Downstream of the mill, the ground material typically continues to a mixer or bin via a screw conveyor or bucket elevator, and aspiration is returned through a square pulse filter. We can provide matched equipment from our product range, including Mixer, Bucket Elevator and Conveyor and TBLMFa Series Square Pulse Filter, so the grinding section arrives as a matched set rather than separate machines.

We design the mill base and support frame to suit the plant layout. During installation we align the direct coupling, verify rotor clearance, check the feeder and magnet, set the hammer-to-screen gap, and confirm that the aspiration duct is sealed so the grinding chamber operates under the intended airflow.

Fully opening the access door isolates the grinding chamber for safe screen changes. Our commissioning procedure includes a no-load rotor run, balanced vibration check, gradual material feed ramp-up, and verification of discharge fineness. Acceptance is based on the output and grind quality agreed in the proposal, using the customer's material and screen.

• Hammers are vacuum-fused with alloy and arranged in a staggered pattern for a longer service life; the reversible rotor doubles hammer utilization.
• Full-width access door allows quick hammer and screen replacement without removing the mill body.
• Imported high-quality bearings and oil seals reduce lubrication intervals and bearing temperature rise.
• Common wear parts and critical components are kept in stock for immediate dispatch, minimizing line downtime.

Our service scope covers operator and maintenance staff training, remote diagnostics, and technical support through the equipment lifecycle. For turnkey projects we also manage installation and commissioning on site.

To prepare an accurate configuration and quotation, we start with the following project data:

1. Raw materials and their typical moisture, oil content and bulk density.
2. Target capacity in tons per hour with the screen size to be used.
3. Particle size requirement for the finished mash or the downstream pellet line.
4. Available motor power supply and the plant's control voltage.
5. Installation layout: available floor space, building height and existing aspiration.
6. Scope of supply: single machine, grinding section, or full feed line engineering.

Can the same hammer mill do both coarse and fine grinding?

Yes. The adjustable hammer-to-screen clearance and interchangeable screens let one machine switch between coarse and fine grinding. We confirm the practical capacity for each grind size before quoting.

What feeder options are available?

We supply either a variable frequency self-cleaning feeder or a belt magnetic separator feeder. The choice depends on whether your priority is automated line control or removing ferrous metal before grinding.

How do I calculate which model fits my feed plant?

Tell us the required t/h at a specified screen size and the material type. For example, an SFSP Series Tear Circle Hammer Mill covers 10.5–45 t/h; the smaller SFSP models cover 2–5 t/h. We match capacity, motor power and feeding method to the rest of your line.

How is the mill protected against foreign metal?

A belt magnetic separator or magnetic plate before the grinding chamber removes tramp metal before it reaches the hammers and screens. We recommend this option for plants that handle raw grain from multiple sources.

Do you support installation and operator training?

Yes. Beyond machine supply, we provide turnkey support from design and manufacturing to on-site installation, commissioning, operator training, maintenance guidance and spare parts. Our projects have been delivered across Europe, Asia and Africa.

What information is needed before a process design?

We need the raw material mix, capacity target, screen size, final particle size, available building dimensions and whether you want a single grinding mill or a complete line. This data allows us to propose the right chamber width, motor power, feeder and aspiration configuration.
