2.Features:

From the input of the product to the discharge of the product after the shot blasting, all are processed by automatic operation.
The main features of this machine are as follows:
(1) High efficiency and uniformity.
Due to the use of the roller mechanism, the drum not only rotates but shakes up and down during steel shot operating. Therefore, the products in the drum are stirred without impact, and the steel shot are evenly shot.
(2) Small pieces and thin-walled pieces are also very suitable.
The cleaning room is manufactured with a roller structure; All kinds of small castings; forgings; stamping parts which may be stuck in other kinds of shot blasting machine also can be handled.

3.Working principle:

First, the preparation work, that is, the dust removal system, separator, elevator, spiral drum screen, drum rotation system, etc., starts to run in sequence, the equipment is ready for work.
Second, load the work-piece into the front hopper, the work-piece enters the drum through the lifting and dumping of the hopper, the gate is automatically closed by the hydraulic cylinder.
Third, the Impeller Head which installed on the gate is activated, and the shot gate valve is automatically opened to start the work-piece cleaning.
The work-piece rotates slightly with the drum while swinging back and forth slightly to receive the steel shot uniformly to remove oxide, welding slag, rust and dirt on the surface of the work-piece until the shot blasting time is reached, the shot gate and Impeller Head are closed.
After the PLC delay, the steel shots mixed in the work-piece completely flow out of the roller, the door opens automatically, and the roller slowly dumps the work-piece.
Then repeat this process until the work is completed and stop in order.
