Granulation equipment series
RL series melting granulator
Detailed description
Overview
RL-type granulator is the use of materials with a melting point below 250 °C, according to the viscosity range of the material in the molten state, through a special distribution device to melt the uniform under the steel belt below the uniform speed, below the strip Under the cooling action of the continuous spraying device, the material is cooled, solidified and packaged in the process of transportation and transportation, so as to achieve the purpose of granulation molding.
Performance characteristics
This product is a new type (melting) molding granulator. Thin steel band heat transfer and atomized spray cooling are used to rapidly solidify the melt and use a single rotating shell. Therefore, easy maintenance, minimal wear and high productivity. Faster handling and replacement of products. The simultaneous running of the drop molding machine and the steel belt can thus produce uniform pellets at a high speed, increase productivity, and increase production profits. It also eliminates dust, improves the environment, and significantly expands the viscosity range. This product is an economical and reliable production process that can process Φ4-12mm particles. These products are very homogeneous, hemispherical, strips and sheets, stable, no thermal stress and high purity and quality. Because the device has a filter plugging device to run more reliable.
Structure (1)
According to the difference of the melting point (solidification point) of the processed product, the temperature viscosity of the material and the cooling effect, the conveying speed and the rotational speed of the head are selected so as not to affect the production capacity and the granular quality.
The machine changed from liquid to solid granular, mainly granulated by granulation die, using rotary steel belt continuous, through spray water cooling set.
Structure (2)
The machine is mainly composed of blanking die granulation forming head, cooling conveying stainless steel belt and pulley, spray cooling system, transmission system, heat preservation device, frame, scraper and other components. The blanking die granulator head is mainly composed of a head die set and a head spindle. The spray cooling system is mainly composed of a spray head, a water tank, and the like. The transmission system is mainly composed of a speed reducer (reducer) speed control motor.
Adaptable Materials
This product is applicable to various materials required for melting point (or softening point) at 50°C-300°C, as well as materials with "supercooled crystallization" characteristics.
Technical requirements
Material must be filtered solid impurities shall not enter the granulator head, otherwise it will cause head wear or clogging, affecting the quality of granulation.
The temperature control should be based on the melting temperature, and the temperature change of the insulation must not exceed ±3°C. Cooling system should be added filter, cooling water temperature is generally between 5 °C -25 °C (water temperature is low, forming fast, good granularity, high yield).
