Boost Bentonite Production Efficiency with Precision Screening Machine

Screening plays a crucial role in optimizing its functionality by controlling particle size to match the needs of specific applications.
Bentonite, a versatile clay mineral valued for its absorbent and swelling properties, is essential across diverse industries. From drilling fluids to cosmetics, bentonite’s unique characteristics make it invaluable, yet challenging to process efficiently. Here’s an overview of bentonite’s applications and the specialized screening techniques that address processing challenges.

Key Applications of Bentonite

  • Drilling Fluids: Bentonite is used in drilling for oil, gas, and water due to its ability to stabilize borehole walls, cool drill bits, and suspend cuttings. Fine particles (75-150 microns/ 100-200 mesh) are crucial here, as they prevent clogging and create a stable slurry.
  • Foundry Sand Binder: In casting molds, coarser bentonite particles (150-250 microns/ 60-100 mesh) ensure structural integrity and prevent excessive dust, helping molds retain their shape during metal casting.
  • Iron Ore Pelletization: Fine, uniform particles (45-150 microns/ 100-325 mesh) improve binding efficiency in pellet formation, ensuring durable, evenly distributed pellets.
  • Cosmetic and Pharmaceutical Use: Ultrafine particles (45-75 microns/ 200-325 mesh) enhance absorption in skincare products, ensuring a smooth texture without grittiness.
  • Cat Litter: Coarse particles (1-2 mm/ 10-18 mesh) are ideal for clumping with minimal dust, creating a user-friendly product.

Processing Challenges and Solutions

Bentonite’s high moisture absorption, fine particle size, and natural variability pose unique challenges during screening. To optimize output and product quality, a range of customized solutions can be beneficial:
  • Clumping and Agglomeration: Moist bentonite tends to clump, clogging equipment and reducing throughput. High-frequency vibrating screens with direct vibration transmission and self-cleaning features are effective for handling moist materials, improving flow and preventing blockages.
  • Dust Management: Fine bentonite particles generate dust, which affects air quality, complicates handling, and impairs product quality. Enclosed screening systems with static housing that enables fixed flange connections, along with integrated dust collection units and precisely calibrated mesh sizes, minimize dust release and prevent clogging.
  • Agglomeration in Bulk Handling: Bentonite can form hard agglomerates that disrupt flow and clog sieves. A vibrating feeder helps maintain consistent material flow, and adding a pre-screening option can further separate larger particles, minimizing blockages and enhancing efficiency in the sieving process.
  • Consistency in Quality: Bentonite’s natural composition varies, impacting moisture retention and particle size. Adjustable screening machines allow for tailored settings, ensuring uniform product quality across batches.
  • Abrasion Resistance: Bentonite’s abrasiveness can wear down screens and conveyor systems. Using wear-resistant materials in screens and feeders, combined with routine maintenance, extends equipment lifespan and minimizes downtime.
  • High-Volume Processing: Large-scale operations need high throughput without sacrificing efficiency. Multi-deck screens and static screens maximize separation efficiency, handling large volumes effectively.

Precise separation of silica and silica gel
The processing of silica and silica gel requires precise and specialized screening technology. These materials, whether as a desiccant, carrier material or additive, pose complex challenges due to their specific properties such as different particle sizes, hygroscopic nature, dust formation and abrasiveness. Especially when used in food supplements, purity and gentle product processing are crucial. Screening ensures compliance with strict quality standards by classifying the materials into particle sizes and removing unwanted particles such as fine dust or oversized particles. This optimizes both further processing and the overall quality of the end product. Screening of silica powder and gel In the processing of silica and silica gel, screening machines are used in several production steps: - Dedusting: removal of fine dust (<0.1 mm/ 140 mesh) to minimize clumping and dust pollution. - Classification: separation into specific fractions, e.g. 0.1-0.5 mm (140 – 35 mesh) for powdery products or 1-6 mm (18-3 mesh) for granulates - Oversize separation:

Exceptional Purity Levels for Sustainable Construction Materials
A pioneering company specializing in the development and manufacturing of equipment for the recycling industry has launched an innovative project in the Netherlands. The goal was to process burned soil as a valuable supplement for building materials. This challenging application, primarily involving dust and ash from burned solids like earth and sand, requires ultra-fine screening at 60 μm (230 Mesh) with highest purity demands. Soil is burned to eliminate harmful organic contaminants, pathogens, and invasive species, which otherwise render the soil unsuitable for construction purposes. By eliminating these impurities, the recycling industry transforms this cleaned soil into a valuable, sustainable raw material for building applications, contributing to a circular economy and meeting high environmental and safety standards. To realize this transformation, the facility was designed to achieve high-precision separation with a throughput of 20 t/h. The fine grain size, along with the abrasive and corrosive nature of the material, and temperatures reaching up to 200°C, required advanced solutions. RHEWUM’s extensive screening trials proved successful, delivering machinery that achieves product purity of nearly

Screening Machines for Explosives
Dust explosions remain a serious threat in industries dealing with explosive low ignition energy materials, particularly in the defense sector. What has to be considered when screening explosive materials? By investing in high-quality, static, and gas-tight screening machines, companies can significantly reduce the risk of dust explosions, ensuring both employee safety and the integrity of their production facilities. In industries handling explosive materials, such as the production of black powder and ammonium nitrate, dust explosions present a significant hazard. Dust explosions are not limited to organic materials but can occur with any finely powdered combustible material that meets specific conditions, especially in high-risk industries. Dust explosions occur when three main conditions are met: # Critical Dust Concentration – Fine particles suspended in air, particularly below 0.4 mm in size, create an explosive atmosphere. For example, the explosion severity index (KSt) for fine materials can exceed 140 (bar·m/s), classifying them as ST1, a moderately explosive category. # Oxygen – The presence of at least 9% oxygen is required for an explosion, making

Hydrogen-tight screening of silicium
Screening the finest silicon powder requires the highest purity standards. Not challenging enough? Then make it gas-tight for hydrogen This is how it works: he highest purity standards are required for the sieving of high-purity silicon powder, which is used in chip and solar panel production. Even the smallest impurities can have serious consequences for the quality of the end product. RHEWUM has risen to this challenge and supplied three RHEsono® screening machines that have been specially developed for screening the finest silicium powder. The focus here was on a special technical requirement: hydrogen tightness. One of the biggest technical challenges was that the screening machines had to be gas-tight, in particular hydrogen-tight (H2-tight). In a hydrogen atmosphere, the hydrogen protects the sensitive silicon powder from unwanted chemical reactions that could be triggered by metal ions (hydrogen passivation). This protective effect is crucial to ensure the high purity of the end product. However, the extremely small hydrogen molecules can pass through steel and cause hydrogen embrittlement, which makes the
