Custom Animal Feed Mixer Machine Manufacturers

Goldlong Machinery And Engineering Co., Ltd. designs and builds feed mixing systems for poultry, livestock, aquatic feed, premix and additive production. We are the Custom Animal Feed Mixer Machine Manufacturers behind a complete range of batch mixers, from compact single-shaft paddle units to high-capacity double shaft machines used in turnkey feed mills. As a China-based feed machinery manufacturer, we combine process engineering, equipment manufacturing, installation, commissioning and after-sales support in one project scope.

Our mixer category covers three proven platforms: SSHJ Series Double Shaft High Efficiency Mixers, SDHJ Series Stainless Steel Single Shaft Paddle Mixers and SLHY Series Ribbon Animal Feed Mixing Machines. The mixer is normally placed between the hammer mill and the pellet mill in a feed production line, and our engineers size the machine according to the batch target, formulation and downstream conditioning capacity.

Mixer Range and Construction Options

The SSHJ double shaft mixer is our high-efficiency option for medium and large batch plants. It mixes powders, meals and liquids at low speed to avoid segregation and uses a three-chain transmission for stable operation. Batch mixing time is typically 40 to 90 seconds, and the coefficient of variation is ≤5% when the mixer is loaded according to its working volume.

SSHJ models range from SSHJ0.1 to SSHJ10, with main power from 2.2 kW to 75 kW. The discharge system is designed as a full-width open gate or a large electric/pneumatic opening to reduce material residue and improve batch turnover.

Material and Configuration Choices

Mixer bodies can be supplied in carbon steel, stainless steel or composite materials depending on corrosion resistance and process requirements. Stainless steel is preferred for premix, fish feed, pet food and formulations with corrosive additives; carbon steel is a cost-efficient choice for standard poultry and livestock lines.

• Three-chain drive is used across the mixer family for stable transmission and long service life.
• Electric or pneumatic large-opening discharge doors reduce material residue and speed up batch turnover.
• Return air systems balance inlet and outlet airflow to limit dust and gas leakage.
• Compressed air cleaning is optional on ribbon mixers to reduce cross-contamination between batches.
• Liquid addition capability supports molasses, oil, water and liquid supplements during the mixing cycle.

Process and Application Fit

The right mixer for a plant depends on the formulation, throughput and downstream process. For high-volume poultry and livestock feed, the SSHJ double shaft mixer matches batch dosing systems and feeds a pellet mill efficiently. For aquatic feed and pet food, the SDHJ stainless steel paddle mixer keeps cleaning simple and reduces material loss. For premix and additive plants, the SLHY ribbon mixer provides gentle, low-speed action and optional air cleaning.

• Poultry and livestock feed: SSHJ or SLHY mixers with short cycles, fast discharge and low residue.
• Aqua feed: SDHJ stainless steel mixer for low material damage, easy cleaning and reduced dust.
• Premix and additives: small-batch ribbon or paddle mixers with high uniformity and cleaning options.
• Molasses and oil addition: mixer residence time and liquid injection points are sized for the formulation; for post-pelleting coating we offer a separate Oil and Liquid Adding System.

Engineering Value and Line Integration

We supply mixers as individual machines or as part of complete feed milling projects. Because our scope includes process design, equipment manufacturing, installation and commissioning, we coordinate the mixer with dosing scales, bucket elevators, screw conveyors, hammer mills and pellet mills. This reduces interface problems and avoids mismatched capacities between the grinding, batching and pelleting stages.

Goldlong provides projects on a turn-key basis, from design and engineering to manufacturing, installation, commissioning and after-sale service. Spare parts supply, operator training and maintenance support are included in the project scope, which helps you maintain stable production after handover.

Quality Assurance and Project Implementation

Our own 14,000 m² manufacturing facility gives us direct control over fabrication, assembly and pre-delivery inspection. We use ERP management to track workshop operations and ensure stable product quality. Before shipment, we carry out inspections covering performance, stability, safety and full system testing.

• Turnkey project implementation and process design
• Installation, commissioning and operator training
• After-sales support with remote diagnostics and rapid response
• Spare parts inventory for wear parts and critical components
• Transparent communication and on-time delivery assurance

Information We Use to Configure Your Solution

A precise mixer proposal starts with the production target, not a generic model. We use the following project inputs to prepare a configuration drawing, motor schedule and quotation:

• Target species and formulation type: poultry, livestock, aqua, premix or additive
• Batch size and required cycles per hour, or the line capacity in tons per hour
• Bulk density, moisture content and particle size distribution of the powders
• Liquid addition type and percentage: molasses, oil, water or liquid supplements
• Required mixing coefficient of variation and any lumping or segregation limits
• Body material preference: carbon steel, stainless steel or composite
• Discharge method: electric or pneumatic operation
• Existing control system and automation interface
• Available utilities: power supply, compressed air, steam or water
• Installation space, discharge height, floor openings and ducting route

Send us your formulation and plant layout together with the capacity requirement. We will confirm a mixer configuration that fits the line and provide the supporting documentation for acceptance.

Frequently Asked Questions

What is the difference between the SSHJ, SDHJ and SLHY mixers?

SSHJ double shaft mixers are designed for high-efficiency batch production with capacities up to 5000 kg per batch. SDHJ single shaft paddle mixers provide compact stainless steel construction for easy cleaning and low dust. SLHY ribbon mixers deliver gentle, low-speed mixing and are well suited to premixes, additives and formulations that require minimal segregation.

Can the mixer handle molasses, oil or water addition?

Yes. Our mixers support the direct addition of liquids such as molasses, oils and water during the mixing cycle. The mixing time and liquid injection arrangement are sized according to the percentage of liquid in your formulation.

Which material options are available for the mixer body?

We offer carbon steel, stainless steel and composite construction. The choice depends on the formulation, corrosion resistance requirements and cleaning protocol. Stainless steel is commonly selected for premix, aquatic feed and pet food lines.

Can you supply the mixer as part of a complete feed mill project?

Yes. Goldlong provides turnkey projects from design and manufacturing to installation, commissioning and after-sales support. We integrate the mixer with hammer mills, pellet mills, sifters, conveyors and control systems according to the required capacity.

What mixing uniformity can be expected?

For SSHJ double shaft high efficiency mixers, the coefficient of variation is ≤5% under normal batch conditions. Final uniformity depends on the formulation, particle size distribution, liquid content and loading sequence.

What information do you need for a mixer quotation?

We need the target batch size or hourly capacity, material characteristics, liquid addition percentage, discharge preference, body material, available power and the existing automation interface. A layout sketch or formulation list helps us identify the right model and configuration.
