Introduction:

Liquid nitrogen pulverizerYDF-81（Vibration feeding payment）It's our companyold modelA new model improved on the basis of liquid nitrogen low-temperature crusher.new modelUsing an independent vibration feeding method,And it retains the manual feeding function, which facilitates batch processing of raw materials while making the feeding speed more uniform and controllable.The discharge port has been upgraded to be adjustable, thus achieving the function of adjusting the discharge fineness within a certain range.The crushing host of this machine utilizesKnife setHigh speed impact and airflow vortex achieve ultrafine crushing of raw materials, using liquid nitrogenIn liquid nitrogencanInternally throughLiquid nitrogen pumpEnter the crusher with the pipeline,Implemented the utilization of raw materialsAlways, continuously, anddirectoffreezeandThe cooling of the crushing chamber is caused by the brittleness of the raw materials due to the freezing of liquid nitrogenFurthermore, it achieves the crushing of tough and heat sensitive materials such as plastic raw materials, polymer materials, rubber, elastomers, etc.The liquid nitrogen input adopts a spherical valve with a dial, and the liquid nitrogen output is quantified, which is convenient for users to use. The low-temperature resistant polytetrafluoroethylene rubber sealing ring has greatly improved the fracture situation of the sealing ring, greatly improving the smoothness of customer use and further reducing the cost of consumables.

1.structurePrinciple:

Small liquid nitrogen low-temperature crusherYDF-81By the crusher host,Feeding sectionIt consists of several parts such as control system, box panel, etc,originalThe material is fed into the crusher by a screw feeder,At the same time, liquid nitrogen enters the interior of the crusher through a liquid nitrogen pump, and the raw materials cooled by liquid nitrogen areThe high-speed rotating blades in the crushing chamber collide and crush, generating a cyclone that uses the flow of the cyclone to crush the raw materialsAnd vaporized liquid nitrogenthroughInternal fineness control structure of the machineBring into the aggregate tank, fine powderCollected by the aggregate bag, the vaporized liquid nitrogen is discharged along with air,Collect through a cyclone separator.

2Application:

Small crusherYDF-81For-Plastic, rubber, polymer materials, household waste, elastomers, polymers, thermosensitive materials, tough materials, etc. can all achieve good crushing effects. Common crushed raw materials include plastic raw materialsPE,PP,PET,PS,PBS,TPUPolyethylene, polylactic acid, modified plastic products, plastic tracks, plastic films, biodegradable tableware, beverage and mineral water bottles, paraffin wax, fruits, food, and more. This machine can be used continuously and can process small batches of samplesHezhong Trial，ButThe minimum crushing amount is10gAt the same time, it meets the requirements of customers for small sample crushing and testing. Compared with similar crushers and grinders, this machine has significant advantages in terms of effectiveness and cost-effectiveness in crushing plastic raw materials and thermosensitive materials. At present, the machine has been successfully applied in multiple quality inspection institutes, testing companies, plastic enterprises, new material companies, petrochemical enterprises, research institutions, and university laboratories in China.

3Characteristics:

1.Integrated design, integrating the crusher host, collection part, feeding mechanism, liquid nitrogen connection part, and electrical control panel into one. The chassis adopts a full304Made of stainless steel plate,Beautiful and elegant, easy to use.

2.The new host adds fineness adjustment function to meet the different discharge requirements of more raw materials.The newly designed riser feeding method ensures smoother liquid nitrogen input, improves cooling efficiency, and effectively eliminates material bouncing problems.

3.liquid nitrogeninputFlexible and versatile, the electric liquid nitrogen pump meets different requirements for small sample crushing and batch processing,optionalThe introduction of intelligent liquid nitrogen pumps provides customers with a higher configuration, more convenient and accurate liquid nitrogen input method.

3.The main machine of the crusher has been continuously improved relying on Taiwan, China's technology, and the structure of non screen air separation has improved the uniformity on the premise of ensuring the fineness of crushing,Can continuously feed and discharge materials,The operating voltage and current of the host are displayed digitally, which is intuitive and convenient.

4.Each part is equipped with independent control switches, and the speed controller can adjust the feeding speed of the feeding motor arbitrarily. The overload protection function effectively protects the motor, and the emergency stop button further ensures the safety of the machine and personnel.

5.The newly customized PTFE rubber low-temperature resistant sealing ring overcomes the drawbacks of the original sealing ring breaking, and its durability has been significantly improved. The aggregate bag can be washed with water or replaced at will, meeting the requirements of different raw material cleanliness.

6.The host box is equipped with a small fan, and ventilation holes are set between the boxes. The cold air after liquid nitrogen gasification is introduced into the crusher motor box through induced draft, realizing the secondary utilization of liquid nitrogen cold air, reducing the temperature of the crusher motor, and improving the operation time and service life.

7.The independent vibration feeder has adjustable speed,Calmly face the feeding speed requirements of different granular raw materials, andguaranteeReserved a manual feeding interface to meet the crushing requirements of a small number of samples.

8.The crusher host in the equipment, as a small ultrafine grinder, has good crushing effects on various materials and can be used separately as a laboratory ultrafine grinder, which greatly improves the cost-effectiveness of the equipment.

9.Rich and practical configuration,Free liquid nitrogen tank mobile base for easy movement and promotion,液氮低温手套，Soak in a basket,safety gogglesSpecial box for liquid nitrogen pump, etcFully configuredEasy to use and convenient to store.
