Drum
type pre cleaner is the main and primary machine in
high capacity grain cleaning industry. Drum type pre cleaner is used to remove
big, small impurity from grain seeds. At the meantime, drum type pre cleaner removes
the light impurity by connecting air dust cleaning system. Base on the
different cleaning aim, drum pre cleaner can be single drum sieve or double drum sieves. So the big straw, long
branches, sands, smashed seeds, dust, etc all can be removed by drum type
pre cleaner. Precleaner is fit for
all type grain seed cleaning, as maize, soya bean, wheat, oat, etc. Its
cleaning capacity ranges from 20-200 ton per hour. Base on different raw
material, different capacity requirement, we will suggest suitable sieves.
Drum type pre cleaner is driven by gear motor
and adopts chain transmission. This construction ensures its stable working
performance. There is a sieve brush equipped and brush the rotation sieves.
This effectively prevents grain seed clogging in sieve holes. Drum pre cleaner has a full-closed cover. This avoids dust leakage during operation and protects
working environment. On top of the pre
cleaner, there is an opening to connect the air suction system. At bottom
of drum type pre cleaner are the impurity and clean outlets. So drum pre cleaner is always placed on a platform or a higher frame to collect the
finished grain.
With good cleaning effect and user friendly
feature, pre cleaning machine is widely used in heavy duty Grain Cleaning Plant,
as grain supply center, big farm, seeds company.

The gestation period for ewes supplemented during pregnancy is 150 days. Within two months of pregnancy, the fetus grows rapidly in the mother's body. At this time, it is also a critical period for the formation of fetal wool. The quality of nutrition for pregnant ewes is related to the birth weight of lambs and the formation of lambs wool. It also directly affects the lactating ability of ewes. The ewes are pregnant during late autumn and early spring. When it is the subtilis season, it is particularly important to supplement the ewe. In the late pregnancy, in addition to normal grazing, fine-wool sheep and semi-fine wool sheep are fed 1 to 1.5 kg of hay each day, 0.25 kg of concentrate, and 15 grams of bone meal. Other types of ewes are reduced as appropriate.
During lactation, supplementation of lactating ewes, each feeding 2 to 2.5 kg of feed, breast milk can increase weight of 0.5 kg. In addition to grazing in the lactation period, it is necessary to give feed as appropriate, especially during the winter and spring lambing period. In the two months before lactation, the ewes produce more nutrients than during pregnancy. At this time, they must feed. The fine-wool ewes supply 1.5 to 2 kilograms of hay every day, and the concentrates are 0.3 to 0.5 kilograms. Feed 0.5 to 1 kg. Salt and bone meal are also indispensable.
The ewes have good "supplement" benefits
Breeding ewes at breeding period to maintain good lye during the breeding period is an important condition for increasing the twinning rate. Before mating, the short-term excellent feeding (15 to 20 days) should be carried out for some ewes with poor body condition to supply a certain amount. The concentrated feed and juicy feeds allow the ewes to reach higher lyrical levels, concentrate the estrus period, have a high conception rate, and shorten the breeding period.
