PRIMARY USES
1. Carbon Retention in CIP and CIL Gold Recovery Circuits
Primary Use: A high-performance interstage screen used to retain carbon in Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) circuits while allowing pulp to flow through. Essential for gold processing plants and mining operations to maintain carbon inventories within each adsorption tank during the gold recovery process.
How it helps: For metallurgists and process engineers, the interstage screen provides reliable carbon retention with low maintenance requirements. The patented design reduces the risk of carbon loss through carryover, which can result in significant economic losses. The screen minimises the need for regular cleaning compared to standard wedge wire screens and, in most cases, does not require backwashing. The design prevents carbon from locking into the screen apertures, reducing wear and extending screen life.
2. Low Maintenance and Long-Life Design
Primary Use: Engineered for long life and low maintenance in aggressive pulp environments.
How it helps: The design minimizes the need for regular cleaning compared to standard wedge wire screens and, in most cases, does not require backwashing . The screen’s construction prevents carbon from locking into the screen apertures, reducing wear and extending screen life .
SECONDARY USES
1. Carbon-in-Pulp (CIP) Circuits: Retains carbon in CIP gold recovery circuits.

1. SAFETY PRECAUTIONS
Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, gloves, and steel-toed boots when handling or maintaining the interstage screen.
Lockout/Tagout: Isolate and lock out the agitator mechanism before any maintenance or inspection work on the screen.
Weight: Some screen units may be heavy. Use appropriate lifting equipment to prevent injury.
Training requirement: Maintenance personnel must be properly trained on the safe and correct procedures for installing, maintaining, and cleaning the interstage screen.
2. FIRST AID MEASURES
Eye Exposure: If pulp or chemicals splash into the eyes, flush immediately with plenty of clean water for at least 15 minutes, holding eyelids open. Seek medical attention.
Skin Contact: Wash exposed skin with soap and water. If irritation develops, seek medical attention.
Inhalation: Not applicable for normal use.
3. FIRE FIGHTING MEASURES
Flammability: The screen is not flammable. Use extinguishing media appropriate for surrounding equipment and materials.
Fire Response: In the event of a fire, evacuate the area and call emergency services. Use appropriate extinguishers.

Bi-Metal Hole Saw Set
A 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.
Egg Incubator
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.
Hose for Air Compressor
A Hose for Air Compressor is a flexible and durable conduit designed to connect the air compressor to pneumatic tools, equipment, or other devices requiring compressed air. Typically made of materials such as rubber, PVC, or hybrid blends, these hoses are capable of withstanding high pressure and provide a pathway for the compressed air to flow from the compressor to the intended application. The hose facilitates the efficient and controlled transfer of compressed air, enabling various pneumatic tools and devices to operate effectively in a wide range of industrial, automotive, and household applications.
Irrigation Pump Set
An Irrigation Pump Set is a complete system designed to move water efficiently from a source—such as a river, well, pond, or tank—to agricultural fields for crop irrigation. It typically consists of a water pump (centrifugal or submersible), an engine or motor (electric or fuel-powered), piping connections, filters, and sometimes a control panel or automation features. These pump sets are vital in agricultural operations, ensuring consistent and controlled water distribution to crops. They are used across small-scale farms to large commercial operations and are compatible with various irrigation methods like drip, sprinkler, or flood systems. Irrigation pump sets are built for durability, high flow rates, and long operational hours in tough outdoor conditions.
Milking Machine
A Milking Machine is a mechanized system designed to extract milk from dairy animals such as cows, goats, and sheep in an efficient, hygienic, and consistent manner. It typically consists of a vacuum pump, pulsator, teat cups, milk container, and tubing system. The machine works by creating a vacuum that gently draws milk from the animal's udder through the teat cups and collects it into a sealed container, minimizing contamination. Milking machines improve milking speed, reduce manual labor, and enhance udder health by maintaining a uniform milking routine. They are essential in dairy farming operations of all scales—from smallholder farms to large commercial dairies—where consistency and hygiene are critical for milk production.
Oil Expeller
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.
Poker vibrator shaft
A poker vibrator shaft, also known as a concrete vibrator shaft or simply a vibrator shaft, is a tool used in construction and concrete work. It consists of a long, slender, and flexible rod or shaft, typically made of steel, with an eccentrically mounted vibrator head at one end. The vibrator head contains an electric or pneumatic motor that generates vibrations.
The primary purpose of a poker vibrator shaft is to consolidate and remove air pockets or bubbles within freshly poured concrete. When the vibrator head is immersed in the concrete mix, the vibrations it generates help to ensure uniform distribution of the concrete, enhance its density, and eliminate voids. This process, known as concrete consolidation, improves the strength and durability of the concrete structure.
Stone Separator
A stone separator is an agricultural or industrial machine designed to remove stones and other unwanted materials from grains, seeds, soil, or construction aggregates. Using vibration, airflow, or gravity-based separation methods, it ensures cleaner, higher-quality end products. Stone separators are commonly used in farming, food processing, milling, and construction to improve operational efficiency and prevent equipment damage from hard debris.
