Introduction of Spiral Chute
The spiral chute is a modern gravity separation machine that utilizes the combined forces of water and gravity to separate minerals based on their specific gravity, resulting in heavy, middling, and light products. This equipment is constructed using fiberglass lined with wear-resistant polyurethane and corundum cover, offering excellent resistance to corrosion, rust, and wear. It is particularly suitable for mining and ore beneficiation, especially in placer mining at seaside, riverside, sand banks, and stream banks. The spiral chute is known for its low water consumption, compact footprint, high concentration and recovery rates, and strong adaptability.

Application of Spiral Concentrator
This device is ideal for processing both metal and non-metal ores that have a significant density difference, such as iron, chromite, pyrite, tin, tungsten, tantalum, niobium, gold, coal, monazite, rutile, and zirconium. It can easily accommodate varying raw material sizes, densities, ore grades, and feed volumes. The spiral chute is suitable for treating materials ranging from 0.6 mm to 0.03 mm, but it performs poorly when there is a high mud content. Currently, it is widely used in the treatment of iron ore, tungsten, tin, niobium-tantalum ores, coastal and riverside placers, and gold ores.

Working Principle of Spiral Chute

  1. Fix the spiral chute in an appropriate location by adjusting the vertical line and securing it with timber.
  2. Use a sand pump to deliver the ore slurry into the two feeding openings at the top of the spiral chute, adding supplementary water to adjust the slurry thickness.
  3. The slurry then flows down automatically and rotates from the top. Under the influence of rotational steam and centrifugal force, the ore and sand are separated based on differences in specific gravity, grain size, and shape.
  4. The final ore is collected in the ore hopper and conveyed through a pipe, while the final sand is collected in the sand hopper and transported to a sand pond via a pipe. Finally, remove the sand pump, completing the entire concentrating process.

Structure of Fiberglass Spiral Chutes
The spiral chute is a gravity separation device that uses inertial centrifugal force generated during helical motion to separate minerals of different weights. Key components include:

  1. Separation Hopper
  2. Feeder Trough
  3. Spiral Section
  4. Stand
  5. Ore Receiving Hopper
  6. Annular Collecting Hopper

Features and Characteristics of Spiral Chute

  1. Compact design with minimal space requirements.
  2. High recovery rate, efficiency, and precise separation.
  3. No need for external power supply.
  4. Resistant to corrosion, rust, and wear.
  5. Easy installation and minimal maintenance.
  6. Low operating cost and long service life.
  7. Strong adaptability to variations in feed amount, density, particle size, and grade.

Metal 3D Printing - Slm / Dmls

METAL 3D Printing - SLM / DMLS
The two technologies have many similarities: both use laser scanning and selectively fuse (or melt) metal powder particles, glue them together and build them layer by layer. Similarly, the materials used in both processes are granular metals.
The difference between SLM and DMLS is due to the basis (and patents) of the particle bonding process: SLM uses metal powder with a single melting temperature and completely melts the particles, while in DMLS, the powder is composed of materials with variable melting points at high temperatures Fusion at the molecular level.
Bering 3D provides 3D printing services for various metal materials such as stainless steel, die steel, titanium alloy, aluminum alloy, and bronze.
