What is a Magnetic De-Stoner?

A Magnetic De-Stoner is a essential equipment which removes heavy contaminants, stones, and impurities from bulk materials. In order to distinguish between lighter materials (such as grains, seeds, or cereals) and heavier, undesired stones or foreign particles, the unit uses a mix of magnetic separation and air classification.This process ensures your end product is free from contaminants, thereby increasing the quality and efficiency of your operations.

Key Features of Magnetic De-Stoner:

Our Magnetic De-Stoners come equipped with a range of key features designed to enhance performance, improve product quality, and optimize your production line:

Powerful Magnetic System:

Our de-stoners are outfitted with strong high-intensity magnets that efficiently attract and separate pollutants of ferrous and non-ferrous metals, as well as stones and other heavy particles, which ensures purity in the final product.

Technology for Air Classification:

Our magnetic destoners can effectively separate heavier and lighter materials, such stones, sand, or any other foreign contaminants, by combining air classification with magnetic separation. This improves the quality of your product.

High Capacity Throughput:

Our magnetic destoners, which are made for high-volume sectors like mineral processing and grain milling, have huge capacities and can maintain production line efficiency even when heavy loads are applied.

Durable and Corrosion-Resistant:

Our magnetic de-stoners are long-lasting and require little maintenance because they are made of stainless steel and other corrosion-resistant materials that can survive difficult conditions like high humidity and corrosive substances.

Applications of Magnetic de-Stoners

• Agricultural & Food Processing Industries

In the agricultural and food processing industry, Magnetic De-Stoners play a critical role in ensuring the safety and purity of consumable goods. They are widely used in rice mills to separate unwanted stones, iron particles, and mud balls from raw and processed rice..

• Minerals & Ceramics Industry

Beyond the food sector, Magnetic De-Stoners are widely used in the mineral and ceramic industries. They are essential for cleaning raw materials like quartz, silica sand, feldspar, kaolin, dolomite, and other non-metallic minerals.

• Chemical and Fertilizer Industries

In the chemical and fertilizer industries, the machines are used to purify powders and granules such as soda ash, potash, urea, lime powder, and various pigments. Impurities in these raw materials can affect the performance of chemical formulations and reduce the shelf life of the final product.

• Recycling and plastics Industries

The recycling and plastics industries also use Magnetic De-Stoners extensively. Plastic recyclers, for example, rely on these machines to clean plastic granules, flakes, and regrind materials. Contaminants like small metal fragments, stones, or heavy plastics can interfere with the extrusion or molding process, making the Magnetic De-Stoner an important pre-processing tool.
