Low temperature pulverizer | low temperature feeder | air conditioning pulverizer | fusible material pulverizer

Gu'an Machinery is specially designed for materials that may stick in high temperature conditions.

For example: low temperature hot melt adhesive, low temperature heat sensitive material, low temperature wax material, etc.

The temperature of the cold air used by this machine can be reduced to minus 5 degrees. According to the temperature of the liquefaction point of the material, the temperature can be adjusted during the crushing process, and the optimal crushing temperature can be selected to reduce energy consumption.

Scope of application

Gu'an cryogenic pulverizer is suitable for various materials that cannot be pulverized at room temperature, such as industrial thermoplastic materials, hot melt adhesives, nylon, polyester, polypropylene, polyethylene, thermoplastic elastomers, TPU, high density polyethylene (HDPE), Pulverization of polypropylene, thermal adhesive, PA1010, low density polyethylene (LDPE), hot melt adhesive for clothing, decorative powder coatings, medicine, modified engineering plastics and other industries.

Gu'an's low temperature shredder is for hot melt adhesive. The pulverization of easy-to-adhesive glue adopts a temperature control device to control the phenomenon that the glue sticks to the knife due to the poor temperature resistance during the pulverization process.

Generally speaking, a temperature control device is added in the low-temperature pulverizer, the temperature of the pulverizing chamber is kept constant between 5-10 °C, the working temperature during pulverization is reduced, and the temperature of the heat-sensitive material is controlled, and the knife does not stick during the pulverization process. Smoother and more efficient.

Features of cryogenic pulverizer

The cutter adopts the shearing type to cut the material at one time.

The cooling method can be water-cooled or air-cooled according to customer requirements.

Using Gu'an's own tool material, the cutting is neat and the wear resistance is strong.

For different elastomers, hot melt adhesives and soft rubbers can be crushed to a minimum size of less than 2mm.

Hot sticky soft rubber crusher, anti-blocking rubber crusher

This series of pulverizers are specially designed and manufactured for a series of plastic and rubber materials that are not resistant to high temperature, such as TPE, TPR, TPU, PU, EVA, pure PP, raw rubber, hot melt elastomer, etc.

Its main feature is that the material is crushed into particles in a low temperature environment of 5-20 degrees.

Elastomer materials are more and more widely used in production and life, because of their stability, temperature resistance and sealing effect that ordinary plastics cannot provide, but the cost of elastomer materials is also much higher than that of ordinary plastics.

Most of the hot melt materials are elastomer materials and rubber materials. The problems they encounter in crushing are:

1. Elastomer materials have low hardness and soft physical properties, and cannot be crushed by impact or extrusion like brittle materials such as ABS.

2. The temperature resistance of hot-melt materials is poor. Most of the materials will show a molten state when the temperature exceeds 70 degrees. Even some materials (such as high-purity PP) begin to melt at more than 30 degrees and begin to interact with each other. Adhesion.

3. Most of the elastomers will generate static electricity after high-frequency friction, which will cause the material to be crushed into granules and unsmooth.

In view of the above characteristics of heat-sensitive materials, Gu'an cryogenic pulverizer has been designed and improved to achieve the following functions:

1. Two kinds of steel with different properties are used for the tool material: high-hardness high-speed steel is used for the cutting edge part, which greatly improves the cutting and crushing ability of the cutting edge (higher hardness than SKD-11 material). The cutting is completed at one time, decisively without sidebands .At the same time of high cutting cutting, it avoids multiple cutting and friction caused by one-time cutting not in place.

2. The knife body is made of steel with low hardness, which enhances its toughness, greatly improves the impact resistance of the knife, and ensures the crushing force of bulk materials.

3. The crushing chamber adopts a low temperature design, so that the material can be crushed in a low temperature environment of 5-20 degrees, so as to avoid sticking due to the melting of the material due to temperature rise. The screen is specially treated to reduce the impact of static electricity. smooth.
