Screening plant is used in a kind of production of plastic grain
Technical field
The utility model relates to plastic grain technical field, screening plant is used in specially a kind of plastic grain production.
Background technique
Plastics definition refers to resin (or in process with monomer direct polymerization) for main component, with plasticizer,
The additives such as filler, lubricant, colorant be auxiliary element, in process can flowing forming material.Plastics are to close
At high-molecular compound, can freely change body styles.Plastics be using raw material monomer with synthesize or condensation reaction polymerize
Made of material.
Plastic grain is the product of plastic product, while being also the raw material of plastics-production and processing, has important production
And researching value, during production and processing, usual people need to carry out plastic grain screening process, sieve plastic grain
Select impurity and underproof plastic grain.
However traditional plastic grain production screening plant, to the short grained impurity and plastics in plastic grain
Grain carries out screening discharging, however the impurity of bulky grain and plastic grain needs are manually rejected, and will lead to bulky grain in this way
Impurity and plastic grain, which can frequently result in, can not complete to remove, to influence the screening quality of plastic grain, and increase work
The workload for making personnel, reduces production efficiency and quality.
