The round pre-cleaner sieve is designed to remove large impurities—such as stalks, stones, and clumps of soil—from raw grain before further processing. This equipment is widely used in grain and oil processing plants, feed processing plants, and grain storage facilities to improve raw material purity and protect subsequent processing equipment.

The SCQY series of circular pre-cleaning sieves offers a range of models with processing capacities spanning from 3–5 t/h to 45–55 t/h, and motor power ratings between 0.75 kW and 4 kW. This equipment can be installed at the beginning of a grain processing production line, before the selection, milling, or feed production processes.

We can provide you with information on your raw material characteristics, required processing capacity, and production line layout to recommend the appropriate model.

How Does a Round Pre-cleaner Work?

The grain Pre-cleaner separates large impurities from raw grain through a mechanical screening process. As the material passes through the cleaning system, unwanted particles are separated from the usable grain according to the equipment’s screening design.

The main purpose of this process is to remove coarse impurities rather than achieve the final cleaning grade. By reducing the amount of foreign material entering subsequent machines, the pre-cleaner helps create more suitable conditions for further grain handling and processing.

Key Benefits of the Round Pre-cleaner

1. Remove Large Impurities from Raw Materials

Raw grain may contain straw, stones, ropes, and other large foreign objects collected during harvesting, transportation, or storage. A wheat pre-cleaner helps remove these materials at the beginning of the processing line, reducing contamination in subsequent stages.

2. Help Protect Downstream Equipment

Large impurities can interfere with the operation of conveyors, elevators, mills, and other processing machinery. Preliminary cleaning helps reduce the entry of unwanted debris into these machines, supporting more reliable operation and reducing avoidable maintenance needs.

3. Support Continuous Processing

Installing a pre-cleaning stage before further processing helps plants manage incoming raw materials more systematically. With large impurities removed early, downstream equipment can handle cleaner material, making the overall workflow easier to manage.

4. Suitable for Grain and Feed Processing Applications

The SCQY round pre-cleaner is designed for use in grain and feed processing facilities. Depending on the raw material and production requirements, it can be incorporated into different processing layouts as an initial cleaning unit.

Applications of the SCQY Round Pre-cleaner

A paddy pre-cleaner can be used in various agricultural material handling and processing applications, including:

  • Grain processing plants: Remove coarse impurities from incoming grain before further cleaning, milling, or other processing.
  • Feed mills: Help clean grain-based raw materials before they enter feed production equipment.
  • Grain storage facilities: Support preliminary cleaning before storage or additional handling.
  • Agricultural processing facilities: Provide an initial cleaning step for suitable raw materials containing large foreign objects.

The appropriate machine configuration should be selected according to the material

Where Does a Round Pre-cleaner Fit in a Grain Processing Line?

The feed pre-cleaner is typically installed near the beginning of a grain processing line, after raw material reception and before more detailed cleaning or processing.

A typical workflow may include:

Raw Material Reception → Soybean Cleaning Machine → Fine Cleaning → Further Processing → Storage or Packaging

The exact arrangement depends on the type of grain, the required cleanliness, and the equipment used in subsequent stages. For plants handling materials with different impurity levels, combining preliminary cleaning with additional screening or separation equipment may help achieve the desired processing results.

How to Choose the Right Round Pre-cleaner

Before purchasing seed cleaning equipment, grain and feed processors should consider several factors:

  • Raw material type: Confirm that the machine is suitable for the grain or other material being processed.
  • Processing capacity: Match the machine’s rated capacity to the actual throughput of the production line.
  • Impurity characteristics: Consider the size, quantity, and type of foreign objects commonly found in the incoming material.
  • Production line layout: Check the available installation space and connections with upstream and downstream equipment.
  • Cleaning requirements: Determine whether preliminary cleaning alone is sufficient or whether additional cleaning equipment is needed.

Discussing these requirements with the equipment supplier can help ensure that the selected machine fits the plant’s operating conditions.
