Overview

GRL seriesSteel strip melting forming granulatorIt is a new and practical melt forming granulator that uses thin steel strip heat transfer and atomized spray cooling to rapidly solidify and form the molten liquid. This machine is an economical and reliable production process that can process particles with a diameter of 4-12mm. These products are very uniform, in the form of hemispherical, strip-shaped, and sheet-like shapes, stable, stress free, and of high purity and quality.

The machine adopts a single machine rotating housing, which makes maintenance convenient, minimal wear and tear, and high productivity; Fast loading, unloading, and replacement of products; The fabric feeder and steel strip operate synchronously, allowing for high-speed production of uniform ingots, improving productivity and increasing production profits; It can effectively eliminate dust, improve the environment, and significantly expand the viscosity range. In addition, the equipment comes with a filtering and blocking device for more reliable operation.

working principle

The machine is mainly composed of a feeding die granulation and forming material feeder, 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 material feeding mold granulation and material feeder is mainly composed of a mold sleeve and a core shaft. The spray cooling system mainly consists of nozzles, water tanks, etc. The transmission system is mainly composed of speed regulating motors, reducers, etc.

The hot melt material from the upstream process is evenly spread on the steel strip moving at a constant speed below it through the granulator feeder. A continuous spray and cooling device is installed below the steel strip to force the material above to cool and solidify quickly during the movement process, thus achieving the purpose of forming granulation. According to physical properties and usage requirements, the fabric dispenser can choose different forms such as intermittent dripping, continuous stretching, and full width overflow to meet the production of products with different shapes such as hemispherical, strip, and sheet.

Features of the equipment

1. Reduce dust and improve operating environment; Continuous operation to improve production efficiency; The particles are regular, and the value of the product is increased.
2. By using thin steel strips for heat transfer and forced spray cooling, the hot-melt material can be rapidly cooled and solidified into shape.
3. Due to the reversing bending of the steel strip at the discharge end, the bonding surface between the solidified material and the steel strip separates, resulting in minimal dust during discharge and complete protection of particle shape.
4. Both the steel strip and the fabric feeder adopt variable frequency speed regulation, which can be conveniently adjusted and controlled according to production capacity, environmental conditions, and physical properties.

Technical Specifications

Technical Requirements

1. Select the conveying speed and feeder speed based on the melting point (solidification point), material temperature viscosity, and cooling effect of the processed product to avoid affecting production capacity and granular quality.
2. The material must be filtered for solid impurities and must not enter the granulation head, otherwise it will cause wear or blockage of the head, affecting the quality of granulation.
3. 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 screen, and the temperature of the cooling water is generally between 5 ℃ -25 ℃ (low water temperature, fast forming, good granulation, high output).
