Fluidized Bed Jet Mill for Ultrafine Powder of Quartz Sand and Silica Micro Powder

Quartz particles processed from crushed quartz stone.

Quartz sand isQuartz stoneQuartz particles produced through crushing and processing. Quartz stone is a non-metallic mineral material that is hard, wear-resistant, and chemically stable.SilicateMineral. The color of quartz sand is milky white or colorless and translucent.Mohs hardness7。

Quartz sand is an important industrial mineral raw material and is not a chemical hazardous substance. It is widely used in glass, casting, ceramics, andFireproof materialsSmeltingFerrosiliconMetallurgical fluxes, metallurgy, construction, chemical industry, plastics,RubberAbrasives, filter media, and other industries.

Main Categories

Quartz has a relatively highFire resistance performanceIn industry, quartz sand is often classified into: ordinary quartz sand,Refined quartz sandHigh-purity quartz sand, fused quartz sand, and silica powder, among others.

Silica fume: Appearance is a gray or gray-white powder, with a refractoriness >1600°C. Bulk density: 200–250 kg/m³. The chemical composition of silica fume is shown in the table below:

The jet mill uses supersonic airflow for pulverization. This model incorporates the fluid dynamics developed by the Aerodynamics Research Institute.By learning numerical simulation software, the optimal flow field and ideal pressure distribution can be calculated to guide the design, greatly improvingIncreased crushing efficiency, reduced energy consumption, and minimal over-crushing. This equipment has the following features:

Equipment Features:

1. This equipment adopts **jet flow technology**, which results in **30% lower energy consumption** compared to domestic models of the same type, while achieving higher output.30% off.

2. After ultra-fine grinding, the finished product is directly obtained without the need for further sieving.

3. Equipped with an airflow regulating valve and a分级 impeller stepless speed controller, the product's particle size can be adjusted without stopping the machine, andThe fine powder can be fully recovered without polluting the environment.

4. Unique flow field design and constant gas-solid concentration control ensure a short residence time of materials in the chamber, preventing materialMaterial adhesion.

5. Increase the filtration area of the dust collector and use waterproof, oil-resistant, and anti-static membrane-coated filter bags to effectively prevent dust accumulation on the filter bags.Adhesion on;6. It adopts a vertical turbine classification device, featuring high rotational speed, wear resistance, and low system power configuration.

7. It can be used in series with grinding equipment such as ball mills, vibration mills, and Raymond mills to form a closed-circuit cycle.

8. The control system can adopt PLC program control, with real-time display of operating status, easy operation, and one-key start/stop functionality.

9. The system operates under negative pressure, with dust emissions not exceeding 10 mg/m³.

10. Ensure product precision, with no large particles present under electron microscope scanning, and maintain a strong classification effect for ultra-fine powders.
