At present, the onion thrips occur seriously, white spots appear on the onion leaves, and the leaves are covered with heavy leaves. If they are not controlled in time, they will cause the leaves to dry, which will seriously affect the production of green onions.

Onion thrips are adults and nymphs are responsible for damage to green onions and tender tips. After the damage, the leaves have long strips of white spots. In severe cases, onion leaves are distorted and brown. Onion thrips adult smaller, afraid of light, and more concentrated activities in the backlight. Cloudy, early morning, late evening, and nighttime are harmful on the surface of onion leaves. After the formation of the spot, many vegetable farmers also used as disease prevention and control, often delaying the timing of prevention and control.

Onion thrips occur 6 to 10 generations a year. Adults, nymphs and cockroaches live in overwintering onions, garlic sheaths or weeds. In the spring of the next year, it will cause damage to garlic. After the early summer, it will seriously damage onions, especially in July and August. Adults are very active, good flying can jump, can use natural wind to migrate and spread. Onion thrips like warm, arid weather. In the rain, the water between the leaves of the onion can cause nymphs to die.

Control methods: In the adult and nymph stage, use 3% acetamiprid EC 2000 times or 10% imidacloprid WP 1500 times to spray foliar every 7-10 days for 2 to 3 consecutive times. The drug was stopped 7 days before harvest.

Single Roller Magnetic Separator

Introduction of Single Roller Magnetic Separator:

The Single Roller Magnetic Separator has one roller in middle of its body with high magnet strenght, its magnet block is half fan-shaped. when grain, seed or powder materials passing by, the magnetic materials such as iron pieces , screws, nuts etc will be stick on the left side of roller where there is magnet, and release when the roller rotate to right side that don't have magnet. so the grain and magnetic materials will discharge from two outlets. 

This type of Magnetic Separator need motor to rotate the roller. it can be used independently or install on Other equipment.

Application of Magnetic Separator :

TCXD series Magnetic Separator can separate iron pieces or ferrous granules from varies materials such as grain, seed, beans, flour, minerals and chemicals etc. 

Specification of Magnetic Separator :
