info@mission-mac.com
The TQLM Series Rotary Cleaner is a versatile grain cleaning machine for removing coarse and fine impurities from wheat, rice, corn, and pulses based on particle size. It achieves ≥80% coarse impurity removal (straw, cobs, stones), ≥60% fine impurity removal (sand, dust, broken kernels), and ≥60% light impurity removal with optional aspiration. Mistaken separation of plump grain is ≤1%, preserving valuable product.
The unit features a dual-layer drawer-type screen design with front and rear sections sliding out from the inlet end for easy inspection and maintenance. Available in five models with capacities from 4 to 20 t/h, the TQLM series serves flour mills, rice mills, feed plants, and grain terminals seeking reliable, scalable rotary cleaning.
Key Features
Proven High Separation Rates With Minimal Good Grain Loss
This Rotary Cleaner achieves ≥80% coarse impurity removal (straw, stones), ≥60% fine removal (sand, dust), and ≥60% light impurity removal with optional aspiration. Mistaken separation of plump grain ≤1%. Balanced performance ensures valuable product is preserved while contaminants are effectively rejected—ideal for quality‑conscious processors requiring HACCP documentation.
Dual-Layer Drawer-Type Screen Design for Easy Maintenance
Both screen layers divide into front and rear sections that slide out from the inlet end for tool‑free inspection, cleaning, and replacement. Eccentric clamping secures screens during operation, preventing grain trapping. This rotary separator simplifies crop changeovers and routine maintenance, reducing downtime and supporting sanitation requirements.
Self-Cleaning Screen System With Cross-Punched Holes
Staggered cross‑punched perforations maximize open area. Medium‑hard rubber balls bounce between screen layers, dislodging near‑size particles to prevent blinding. This passive self‑cleaning action maintains consistent throughput and separation efficiency without added power. The grain cleaning machine handles variable moisture or clog‑prone materials reliably.
Low-Noise Inertial Vibration Drive With Smooth Start-Stop
An inertial vibration mechanism eliminates complex linkages, reducing noise (typically <75 dB). Vibration dampers absorb energy, preventing transmission to the structure. Smooth start‑stop minimizes mechanical shock and wear. This Rotary Cleaner creates a more comfortable work environment, supports noise regulation compliance, and extends component life.
Integrated Aspiration Channel for Light Impurity Removal
An optional built‑in aspiration channel removes husks, chaff, and dust (≥60% efficiency) using adjustable airflow. Combines size‑based and density‑based separation in one pass, eliminating separate aspiration equipment. Connects to external dust collection for higher capture. This rotary screening machine reduces capital and floor space while delivering thorough cleaning.
Durable Construction With Optional Stainless Steel
Carbon steel with anti‑corrosion coating (stainless steel optional) resists rust and abrasion. Sealed bearings, durable screen frames, and robust clamping ensure long service life. Easy maintenance access and low total cost of ownership make the Rotary Cleaner suitable for flour mills, rice mills, feed plants, and grain terminals handling wheat, corn, rice, or pulses.

Grain rotary cleaner efficiently removes dust, husk, and impurities from wheat, rice, corn, and pulses, ensuring higher purity and better quality for storage and processing.
FAQ
What is a rotary cleaner used for in grain processing?
A rotary cleaner removes coarse impurities such as straw, cobs, and stones, along with fine impurities including sand, dust, and broken kernels from grain based on particle size differences. It can also remove light impurities when equipped with an aspiration channel.
How does the TQLM rotary grain cleaner work?
Material enters the rotating screen assembly; oversize particles (coarse impurities) discharge at the end while smaller particles (clean grain and fine impurities) fall through screen openings. Fine impurities are separated through the lower screen, and optional aspiration removes light impurities.
What separation efficiency can I expect?
The TQLM series achieves ≥80% removal of coarse impurities, ≥60% removal of fine impurities, and ≥60% removal of light impurities when equipped with aspiration. Good grain loss is limited to ≤1%.
What is the difference between a rotary cleaner and a vibration separator?
Rotary cleaners are typically used for high-volume pre-cleaning with gentle product handling. Vibration separators offer finer classification capabilities with multiple screen layers and are often used for final cleaning.
How often should screens be cleaned or replaced?
Screen cleaning is continuous via the rubber ball system. Visual inspection weekly is recommended. Screen replacement frequency depends on throughput and material abrasiveness, typically every 12-24 months for moderate use.
Can the TQLM rotary cleaner handle sticky or high-moisture grains?
The machine is optimized for dry grain processing. For sticky or high-moisture materials, the self-cleaning rubber ball system helps reduce blinding, but performance may vary. Contact our technical team for application-specific recommendations.
