Rice Grader
WhatsApp Order
A Rice Grader is a specialized agricultural and industrial machine used to classify rice grains based on size, shape, or weight during the post-harvest processing stage. It is essential in rice mills and grain processing plants to ensure consistent product quality by separating broken, small, and full grains. The grading process increases the value of the rice, improves packaging consistency, and ensures compliance with commercial standards.
Description
Uses
- Size Grading
o Sorts rice grains into uniform sizes for improved appearance and packaging.
o Removes broken or undersized grains that reduce market value. - Shape Sorting
o Separates grains by shape for specialty rice varieties requiring uniform grain structure. - Post-Milling Quality Control
o Applied after dehusking and polishing to remove irregular grains. - Foreign Material Removal
o Eliminates fine debris, husks, or small stones through mesh or vibration-based separation. - Commercial Processing
o Used in large-scale rice milling operations for high-throughput sorting and grading. - Product Value Enhancement
o Improves the grade of rice to meet export or local premium market standards. - Packaging Preparation
o Prepares sorted grains for efficient and accurate packaging based on grade.
SAFETY HANDLING PRECAUTIONS
Safety Precautions
- Wear Protective Gear
o Use dust masks to protect against airborne rice particles.
o Wear safety goggles when near moving or vibrating parts.
o Use gloves during cleaning and maintenance tasks. - Inspect Machine Before Use
o Check for worn or loose screens and ensure components are properly aligned.
o Confirm safety guards and covers are intact. - Operate Safely
o Do not exceed input capacity to avoid jamming or motor strain.
o Keep hands and tools clear of vibrating or rotating components. - Maintain a Safe Work Area
o Keep floors dry and free of spilled grain to prevent slips.
o Ensure good ventilation to reduce dust accumulation. - Electrical Safety
o Check electrical connections and use grounded outlets.
o Do not operate in damp conditions. - Routine Maintenance
o Clean screens, hoppers, and moving parts after each use.
o Lubricate and inspect mechanical systems regularly. - Training and Supervision
o Only trained personnel should operate the grader.
o Operators should be familiar with emergency stop controls and shutdown procedures.

Bi-Metal Hole Saw Set
A 9 PCS Bi-Metal Hole Saw Set refers to a collection of nine hole saws, each constructed with a bi-metal design. A hole saw is a cylindrical cutting tool used to create holes in various materials such as wood, metal, plastic, and more. The term "bi-metal" indicates that the hole saws are made from two different types of metals, typically high-speed steel (HSS) and a more durable alloy like cobalt. This combination enhances the hole saw's cutting performance, making it suitable for a wide range of applications and providing increased durability and longevity. The set typically includes hole saws of different sizes to accommodate various hole diameters, making it a versatile tool for professionals and DIY enthusiasts alike.
Die Set
An "8 PCS DIE SET" typically refers to an 8-piece die set used in various manufacturing and machining processes. In manufacturing and metalworking, dies are specialized tools used to shape, cut, or form materials such as metal, plastic, or other substances. A die set, in this context, is a collection of individual dies designed to work together for specific tasks.
Direct Drive Air Compressor
A direct drive air compressor is a type of air compressor where the motor is directly connected to the compressor pump, typically without the use of belts or gears. In this configuration, the motor and the pump share a common shaft, resulting in a more compact and efficient design. Direct drive compressors are known for their simplicity, reduced maintenance requirements, and higher power transmission efficiency compared to belt-driven or gear-driven counterparts. They are commonly used in various applications, including powering pneumatic tools, inflating tires, and providing compressed air for industrial processes.
Egg Incubator
 PRODUCT DESCRIPTION
An egg incubator is a specialized device designed to artificially hatch eggs by maintaining optimal temperature, humidity, and ventilation conditions. This equipment simulates the natural environment provided by brooding birds, ensuring consistent warmth and air circulation to promote healthy embryo development. Egg incubators are widely used in poultry farming, hatcheries, research, and educational settings to increase hatch rates, control breeding cycles, and improve the efficiency of egg hatching processes.
Oil Expeller
PRODUCT DESCRIPTION
An Oil Expeller is a mechanical device used to extract oil from oil-bearing seeds and nuts through a process of high-pressure mechanical pressing. It typically consists of a screw shaft, pressing chamber, and power system (manual, electric, or engine-driven), and is widely used in small-scale farms, local oil mills, and commercial processing units. Capable of handling materials like sunflower seeds, groundnuts, soybeans, mustard, coconut, and sesame, oil expellers are available in both cold press and hot press variants. This machine enables efficient, chemical-free oil extraction, producing unrefined oil and residual seed cake for further use.
Pedestal Grinder
 PRODUCT DESCRIPTION
A Pedestal Grinder is a robust, stationary grinding machine mounted on a pedestal stand and designed for heavy-duty grinding, sharpening, shaping, and polishing tasks. It typically features two grinding wheels—coarse and fine—on either end of a motor-driven shaft. Widely used in workshops, fabrication units, and maintenance departments, pedestal grinders are ideal for sharpening tools, removing burrs, cleaning welds, and refining metal components. The fixed design ensures stability, while adjustable tool rests and safety guards enhance control and operator protection during high-speed grinding operations.
Pellet Machine
 PRODUCT DESCRIPTION
A Pellet Machine is an industrial-grade device used to compress powdered or ground raw materials into dense, cylindrical pellets. Commonly used in animal feed production, biomass energy generation, and organic fertilizer processing, it works by applying heat and mechanical pressure through a die and roller system. This transforms materials such as sawdust, straw, cornmeal, rice husks, and feed mixtures into uniform pellets. The resulting pellets are easier to handle, store, and transport, and offer improved performance in combustion, feeding, or fertilization.
Stone Crusher
 A stone crusher is a heavy-duty machine designed to reduce large rocks into smaller stones, gravel, or rock dust for use in construction, road building, and other aggregate applications. These machines use mechanical force to break down stone material, typically through compression or impact. Stone crushers come in various types such as jaw crushers, cone crushers, impact crushers, and hammer crushers, each suited to specific crushing requirements. They are widely used in mining, quarrying, construction, and recycling industries to produce consistent aggregate sizes for foundations, concrete, asphalt, and more.
