RL series melting granulator

Summary

The RL type granulator utilizes the melting point of materials below 250 ℃. Based on the viscosity range of the material in its molten state, a special distribution device is used to evenly distribute the molten liquid on the steel strip that moves uniformly below it. Under the cooling effect of a continuous spray device set below the steel strip, the material is cooled, solidified, and packaged during transportation, thereby achieving the purpose of granulation and molding.

Performance characteristics

This product is a new type of (melting) forming granulator. Using thin steel strips for heat transfer and atomization spray cooling, the molten liquid is quickly solidified and formed, using a single machine rotating shell. Therefore, maintenance is convenient, wear is minimal, and productivity is high. Quick loading, unloading and replacement of products. And the falling mold forming machine and steel strip operate synchronously, which can produce uniform ingots at high speed, improve productivity, and increase production profits. And it can eliminate dust, improve the environment, and significantly expand the viscosity range. This product is an economical and reliable production process that can be processed Φ 4-12mm particles, these products are very uniform, appearing in hemispherical, strip, and sheet shapes, stable, heat stress free, and have high purity and quality. Due to the equipment's built-in filtration and blockage removal device, it operates more reliably.

Structure (1)

Select the conveying speed and head speed based on the melting point (solidification point) of the processed product, material temperature viscosity, and cooling effect to avoid affecting production capacity and granular quality.

This machine transforms from liquid to solid particles, mainly through granulation die head granulation, using a rotating steel strip for continuous processing, and shaping through spray water cooling.

Structure (2)

This machine mainly consists of a feeding mold granulation forming machine head, a cooling and conveying stainless steel belt and pulley, a spray cooling system, a transmission system, an insulation device, a frame, a scraper, etc. The cutting mold granulation machine head is mainly composed of a machine head mold sleeve and a machine head core shaft. The spray cooling system mainly consists of nozzles, water storage tanks, etc. The transmission system mainly consists of a gearbox (reducer), a speed regulating motor, etc.

Adapt to materials

This product is suitable for various materials with a melting point (or softening point) between 50 ℃ and 300 ℃ that require granulation, as well as materials with "supercooled crystallization" characteristics.

Technical requirement

The material must be filtered and solid impurities must not enter the granulator head, otherwise it may cause wear or blockage of the head, affecting the quality of granulation.
The temperature control should be determined based on the melting point temperature, and the insulation requirement is that the temperature change should not exceed ± 3 ℃. The cooling system should be equipped with a filter, and the temperature of the cooling water is generally between 5 ℃ and 25 ℃ (low water temperature, fast molding, good particle shape, and high yield).

Summary

This product is a new type of (melting) forming granulator. The work changes from liquid to solid through transportation and cooling, and materials with a melting point range of 50 ℃ to 300 ℃ can be granulated and formed. Dust free, improving the production environment; And it has certain economic value (energy saving, packaging container economy), fast product replacement, beautiful granular products, uniform nearly hemispherical granular shape, no thermal stress; Granular products are not only easy to package, transport, store, but also convenient for users to measure, mix or remelt, and can be continuously produced. From feeding to packaging, it reduces physical labor, has stepless speed regulation, adjustable flow rate, and is easy to operate. Widely used in industries such as petroleum and fine chemicals. One machine can be used to make strips, cut into pieces, and flakes; Toxic materials can be enclosed in a group.
