Fire prevention measures for twin-screw granulators 

1.Condition

Often check the running condition of the twin-screw granulator, check whether the joints are solid, there is no electrical sparks occurring, electrical and mechanical equipment overload, short circuit protection equipment performance is firm, whether the equipment insulation is up to standard.

2、Reasonable selection

There are flammable and explosive substances in the place, equipment and use of twin-screw granulator, it is appropriate to use explosion-proof electrical appliances, insulated wires need to be sealed and laid in the steel pipe. Should be selected according to the level of explosion risk places, equipment and electrical equipment.

3, adhere to the safe location of the equipment

Adhere to the necessary safety distance is one of the effective measures of twin-screw granulator fire. In order to avoid twin-screw granulator sparks and risk of high temperature caused by fire, as long as the sparks and risk of high temperature can occur around the twin-screw granulator should not be stacked flammable and explosive products.

4, adhere to normal operation

Twin-screw granulator running sparks and risk of high temperature is the main cause of electrical machinery fire. In order to manipulate the excessive work sparks and risk of high temperature, to ensure the normal operation of the twin-screw granulator, should be operated by trained and qualified personnel to use protection and maintenance.

5、Ventilation

In the flammable and explosive risk of running the twin-screw granulator, there should be better ventilation to reduce the concentration of explosive mixtures. Its ventilation system must meet the relevant requirements.

6, grounding

In the flammable and explosive risk places of grounding than the general place of high requirements. Regardless of its voltage, normal non-electrified equipment should be firmly grounded in accordance with relevant regulations.
