Construction

The B40 Brushing Machine features a large diameter drum with rotating nylon brushes and spiral flighting within a perforated concave screen (separation area of 2.3 m2).

One additional grid of different perforation size is supplied with machine. Additional screens are available.

Adjustable flaps below drum direct leaf on to take away conveyor (if required).

Operation

The dried whole crop (pre-cutting unnecessary) should be fed to hopper (by conveyor etc.). A separate conveyor is required to take away the graded leaf. Stems are discharged out of end of drum.

Option

M40S – Pneumatic Leaf Separator – for separation of small stem pieces still attached to leaf after brushing. A fan with 0.55 kW motor and adjustable air control slide blows the leaf into settling chamber – heavy product (stem pieces) fall from first outlet and are then separated from leaf.
