Lithium, beryllium, niobium, tantalum ore industry requirements, "rare metal mine geological exploration specification (Trial)", the development of the lithium, beryllium, niobium, tantalum deposit industrial index reference issued in China in 1984. Among them, lithium, beryllium cutoff grade and industrial grade mineral deposits are divided into stone hand and machine ores, and were determined grade index. Hand selection and machine selection ore division, according to production practice experience, if the spodumene particle size in the ore body is >3cm, the ore grade is above 2%~3%; the beryl particle size is >0.5cm, the ore grade is 0.1%. ~ 0.2% or more, suitable for hand selection, divided into hand-selected ore, and hand-selected mineral reserves calculation. Niobium, tantalum iron ore particle diameter> 0.3cm, in the mining process may be included with hand-selected. Hand-selected ore tailings are machine-selected and not suitable for hand-selected ore, all of which are machine-selected ores. Lithium, tantalum, niobium, tantalum, etc. are sometimes associated with each other to form a comprehensive deposit, or associated with polymetallic deposits such as tungsten and tin , and have comprehensive mining and comprehensive utilization value, and should be comprehensively evaluated in the geological exploration process. Hot Cutting Extrusion Pelletizer
LINA Extrusion Pelletizer
Most of the polymer must be kneaded and then granulated before it is made into a final product. Sorted by pelletizing ways, LINA rubber & plastic granulator can be divided into four categories: 1. Hot-cutting and air-cooling pelletizing method. 2. Under-water granulating method. 3. Water-strand extrusion method. 4. Water-ring granulation method. LINA pelletizer can meet the granulation needs of high-viscosity and low viscosity rubber and plastic materials, as well as some new materials and chemical additives.
LINA Die Surface Hot Cutting Pelletizing Machine
LINA`s die surface hot cutting and air cooling granulating machine is suitable for polymers that are sensitive to heat and long residence time, such as PVC, TPR, PE, cross-linked PE and so on. The flow path of the polymer from the extruder to the pelletizing port should be kept as short as possible with minimal heat. When polymer is extruded through the die surface, the rotating blade cuts the extruded materials into particles. After the pellets are cut, they are removed from the rotary blade and caught by cooling air circulating in the pelletizing room. The air stream preliminary cools the surface of the pellets and takes them out of the pelletizing room and sends them to the cooling zone.

Advantage of LINA Pelletizing Line
1. The unit has the whole unit process chain, sound and light failure alarm and fast lock fault point and other control functions. All parts that are in contact with the material are made of stainless steel.
2. High accuracy of temperature control system to ensure the temperature sensitivity of the material.
3. It adopts the drop type separating method after cutting process, to avoid Particle agglomeration and ensure particle cooling.
4. Feeding system of the pressing machine adopts heater and reversing device to solve problem of power outage, material crash and cleaning.
5. Especially, the barrel and die head adopts advanced foreign techniques to ensure and control the dangerous occurred when the pressure is uncontrollable. The honeycomb filter plate is easy to clean and quickly change the mesh and the die head t easy to leak.
6. The hoist adopts automatic return technology to ensure the working efficiency.
7. The technological combination of dual-pull forced feeder and single screw not only meet the high requirement of secondary continuous mixing, but also solve the problem of time and power consuming of traditional working process.
