Custom Feed Pre-Cleaner Manufacturers

Cleaning equipment refers to a class of devices specifically designed to reduce dust concentration in workshops and optimize the production environment, widely used in the feed industry. These devices mainly include dust collectors and powder cleaning screens. Dust collectors, through efficient filtration systems, effectively capture fine dust particles in the air, preventing dust pollution and improving air quality; powder cleaning screens quickly and effectively remove substandard particles, ensuring material purity and production stability. This equipment not only enhances the safety of the working environment and reduces the health hazards of dust to employees, but also extends the lifespan of production equipment and increases production efficiency.

Cleaning equipment features a compact design, small footprint, and ease of installation and maintenance. Its high efficiency and stability make it an ideal choice for feed processing workshops, especially providing strong support in environments requiring large-scale dust control. By employing advanced filtration technology and a rational layout, cleaning equipment can significantly reduce dust concentration in production workshops, creating a cleaner and more comfortable working environment.

Industry knowledge

Goldlong Machinery And Engineering Co., Ltd. designs and builds Custom Feed Pre-Cleaner equipment at our own manufacturing facility in Liyang City, Jiangsu Province, China. Our pre-cleaner range is supplied as individual machines or as part of a complete feed mill, grain receiving, or biomass processing line. We are a Custom Feed Pre-Cleaner Manufacturers supplier that carries the project from requirement analysis and process design through manufacturing, installation, commissioning, training, and spare parts service.

Pre-cleaning is the first mechanical treatment that raw ingredients receive. It protects hammer mills, mixers, pellet mills, and extruders from stones, metal, straw, husks, dust, and oversize or compacted fractions. Our two machine families cover whole-grain and powder applications with capacities from 10 t/h up to 120 t/h.

Pre-Cleaner Product Range and Positioning

Our Pre-Cleaner category currently includes two machine families. Each is configured around the material being cleaned, the target capacity, and the space available in the existing or new line.

SCY Series Rotary Pre-Cleaning Sieve

For whole grain, maize, wheat, soybean, and other granular raw materials. Available in SCY50, SCY63, SCY80, SCY100, and SCY130, with capacity from 10–20 t/h to 80–100 t/h and installed power from 0.55 kW to 1.5 kW. The reverse feeding design and spiral discharge section inside the screen cylinder improve screening efficiency, while the cleaning mechanism on the outer wall reduces screen blinding. Screen aperture combinations are selected according to the impurities to be removed and the size distribution of the usable grain.

SQLZ Powder Cleaning Sieve

For powdery materials such as maize meal, bran, premix base powders, and other ingredients that tend to form clumps. The SQLZ series breaks up and removes clumps and oversized particles while maintaining high output and low power consumption. Standard models SQLZ60X50X100, SQLZ75X65X140, and SQLZ125X100X200 cover 40–50, 50–70, and 100–120 t/h at 5.5, 7.5, and 15 kW. Different sizes of sieve holes can be fitted to match the required separation effect.

Standard Models and Capacity Range

Model Capacity (t/h) Power (kW) Typical Application
SCY50 10–20 0.55 Whole grain pre-cleaning before grinding or storage
SCY63 20–40 0.75 Grain intake and pre-grinding cleaning
SCY80 40–60 1.1 High-capacity grain receiving lines
SCY100 60–80 1.5 Large feed mill intake systems
SCY130 80–100 1.5 Commercial grain terminals and feed mills
SQLZ60X50X100 40–50 5.5 Powder cleaning and de-lumping
SQLZ75X65X140 50–70 7.5 Meal and premix powder circuits
SQLZ125X100X200 100–120 15 Central milling and large feed plants

Where Our Pre-Cleaners Fit in the Process

In a typical feed mill, the pre-cleaner is installed after the intake hopper and before the bucket elevator or directly before the hammer mill. For grain intake, the SCY series removes straw, stones, soil, broken grain, and oversized impurities before storage or further cleaning. For powder systems, the SQLZ series is positioned before mixing or dosing to remove clumps and oversized particles that affect weighing and mixing accuracy.

  • SCY: intake pit, grain receiving, pre-grinding, and grain drying lines.
  • SQLZ: meal handling, premix plant, and post-grinding powder circuits.

Pre-cleaning directly protects downstream machines such as our Hammer Mill, Mixer, and Pellet Mill. In turnkey projects, the cleaning step is interlocked with bucket elevators, screw conveyors, rotary sifters, and dust collection so the whole line starts and stops in a safe sequence.

Sizing and Configuration

Pre-cleaners are selected on working capacity, not average throughput, because raw material intake is often delivered in surges. We confirm the required flow, impurity level, and available height before proposing a model.

  • Capacity: the model is chosen so peak intake stays inside the rated range.
  • Screen aperture: aperture combinations determine the separation effect; we provide different sizes for SCY and SQLZ models.
  • Power and drive: motors are matched to local voltage and frequency.
  • Installation: the compact machine design reduces footprint and supports simple retrofit in existing buildings.
  • Dust control: cleaning equipment lowers workshop dust concentration and can be combined with a pulse filter where required.

Quality Assurance and Acceptance

Each pre-cleaner is manufactured under ERP-controlled workshop management and inspected before shipment for performance, stability, safety, and full system operation. When the project requires a non-standard interface, we can develop and manufacture from customer drawings or samples.

  • Pre-delivery inspection covers mechanical movement, screen fit, drive alignment, and safety protection.
  • On-site commissioning verifies capacity, separation effect, noise, vibration, and safe operation.
  • We provide operation and maintenance training for your team.

Project Support and After-Sales Service

We supply pre-cleaners as single machines for replacement and as integrated equipment in turnkey feed projects. The same engineering team handles process design, equipment manufacturing, installation, commissioning, and training.

  • Project implementation: requirement analysis, process design, solution confirmation, manufacturing, installation, commissioning, and ongoing support.
  • After-sales service: dedicated engineers, remote diagnostics, regular follow-ups, and 24-hour rapid response.
  • Spare parts: commonly used wear parts and critical components are kept in stock for fast dispatch.
  • Training: operational guidance and maintenance support that help the plant run independently.

Information We Use to Configure Your Solution

To prepare an accurate proposal, we need the operating context of the pre-cleaner. The more complete this information is, the closer the delivered machine will be to your requirement.

  • Raw material type and moisture level.
  • Impurity profile: straw, stones, dust, broken grain, lumps, and oversized particles.
  • Target cleaning capacity in t/h and peak intake rate.
  • Process location: intake, before grinding, before mixing, or after drying.
  • Required separation fractions and preferred screen apertures.
  • Available footprint, installation height, and direction of material flow.
  • Power supply voltage, frequency, and control interface.
  • Whether the machine is for a new line, an extension, or a retrofit.
  • Destination country and project schedule.

Pre-Cleaner Procurement FAQs

What is the difference between the SCY and SQLZ pre-cleaners?

The SCY Series Rotary Pre-Cleaning Sieve is designed for granular materials such as maize, wheat, and soybeans.
