Small Cryogenic Grinder Cryomill Cryogrinder with Liquid Nitrogen for Laboratory Use

Introduction

The Laboratory plastic crusher(Cryomilling) is a specialized equipment designed by our company, catering to the needs of the plastics industry, quality inspection sector, and laboratory settings.

This machine is primarily utilized for sample crushing, especially for heat-sensitive materials and polymer substances like plastics, rubber, polylactic acid, and various other materials such as PE, PP, PET, PS, PBS, TPU, among others. Its minimum crushing capacity of around 10g makes it ideal for small-scale sample crushing and testing requirements. 

Equipped with a liquid nitrogen tank and a pump or self-pressurized tank, this crusher leverages cryogenic effects to render materials brittle, achieving ultra-fine crushing. 

The incorporation of a high-speed rotating impact blade and cyclone air flow separation facilitates this ultra-fine crushing process, making it effective for a wide range of dry materials in industries spanning plastics, rubber, pharmaceuticals, cosmetics, and more.

• Cryogenic effect of liquid nitrogen for ultra-fine crushing of tough materials
• Good pulverizing effects on a variety of materials for versatile applications in various industries

Principle

The liquid nitrogen low-temperature pulverizer is combined with a liquid nitrogen tank and a liquid nitrogen pump (pedal type + electric pump). It uses the cryogenic effect of liquid nitrogen combined with the powerful crushing capacity of the ultra-fine pulverizer to achieve ultra-fine crushing of high-toughness raw materials.

The main machine of the crusher is composed of a feeding port, a collecting tank, a crushing chamber, a high-speed motor, etc. The material enters the crushing chamber from the feeding port. At the same time, the liquid nitrogen is pressurized by the liquid nitrogen pump and enters the interior of the crusher in the form of gas-liquid mixture. The raw material becomes embrittled when exposed to liquid nitrogen and is impacted and crushed by the high-speed rotating blade (25000r/min). The high speed of the blade The rotation also causes the flow of air flow, which brings the crushed materials to the crushing tank. The liquid nitrogen is vaporized and the air is discharged through the filter bag to complete the crushing.

The pulverizer host in this equipment is a small ultra-fine pulverizer that has good pulverizing effect on a variety of materials, and can be used alone as a laboratory ultra-fine pulverizer. The dual-use of one machine greatly improves the efficiency of the equipment. Value for money.
