"NPO Center" offers consumers crushing complexes on a gas-static support for obtaining up to 40 t/h of several narrow fractions of the final product in the required size range (-0.02 ... -0.5 mm) under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

The KI grinding complexes on a gas-static support provide for obtaining up to 40 t/h of several narrow fractions of the final product in the required size range (-0.02 ... -0.5 mm).

The KI grinding complexes are successfully used in the production of mineral powder, cement, microcalcite micropowder, etc.

The method of centrifugal impact grinding, implemented in the grinding complexes of NPO Center, allows obtaining a material characterized by quality indicators unattainable using other types of grinding. The crushed product has a high specific surface area and physicochemical activity of particles, has a specified narrow granulometric composition.

The reduction in specific energy intensity and the absence of over-crushed classes is ensured by the iterative (continuous) cycle of the KI complex - "grinding - separation - continuous removal of the finished product fr om the grinding process".

The KI grinding complexes are a coordinated modular system of units: mills, fans, cyclones, classifiers, filters, automation and control systems.

The initial product is fed into a rotating accelerator. Having received the required peripheral speed for grinding, it flies out of the accelerator, hits the impact surface of the crushing chamber and is destroyed. It is then picked up by the air flow and carried out to the classifier, which is part of the mills, wh ere it is separated. The under-crushed material is returned for final grinding, the material of the required size is carried out to the cyclones, where it settles and enters the finished product bin.

This scheme allows to significantly improve the economic indicators of the grinding process, reduce the specific energy intensity, prevent over-grinding due to the continuous removal of the finished product and improve the quality indicators of the resulting material. The required size can be adjusted during operation without stopping the equipment.

The equipment of the grinding complex does not cause dusting because it operates under vacuum.

Air consumption is minimized due to the closed circuit of air flow use. Only a small part of the air used in the grinding process is released into the atmosphere.

Before entering the atmosphere, the air undergoes a multi-stage purification system and meets all environmental standards and requirements.

The material obtained in the mills of NPO Center is characterized by a narrow granulometric composition (low content of both large and small fractions).

Due to the centrifugal impact grinding method, the particles have a uniform isometric shape with a well-developed surface. This helps to obtain durable and high-quality products while reducing material and energy costs.

Stability of grinding characteristics: product quality does not depend on the condition and degree of wear of quickly wearing elements and equipment.

Narrow specified granulometric composition in the entire possible range of grinding size (from -0.02 to -0.5 mm).

Possibility of obtaining several fractions of the finished product simultaneously.

Obtaining isometric products with increased particle activity.

Low energy consumption.

The basic configuration of the KI is equipped with a modern automated control system and an interactive control panel, a system for analyzing work, recording and collecting statistics, taking into account various options and required parameters of the final product.

Adjustment of grinding fineness and distribution of products by size without stopping the operation of the complex.

Individual configuration, depending on the properties of materials, size of products, requirements for weight and size characteristics.

There is a possibility of implementation in existing process lines.

Compared to other methods of grinding materials, the reduction in energy costs is from 12 to 56%.

To develop a specific scheme of the crushing complex, determine the size, design and configuration of the equipment that most fully meets the needs of the Customer, it is necessary to contact the company's specialists or fill out a questionnaire and send it to the address of "NPO Center".
