How many types of ball mill feeders are there? What kind of work does the various feeders apply to?

The drum feeder is shaped like a circular drum with two openings. Inside the cylinder, there is a spiral feeder. When the ore is rotated with the ball mill , the ore is sent into the ball mill along the spiral. The drum type feeder is suitable for adding dry materials to the ball mill, so it is applied more when the ball mill is open for grinding.

A spiral feeder (also known as a spoon-type feeder), which is a spiral-shaped spoon with a replaceable spoon at the end of the spiral. A hole in the center of the side of the ore feeder is connected to the hollow shaft of the ball mill to the ore end, and the ore is thus fed into the ball mill. The spiral feeder is divided into three types: single spoon, double spoon and three spoon. The spiral feeder is suitable for wet feeding, which is usually used in the ball mill and classifier closed-circuit grinding cycle (that is, the ball mill can only install the feeder when the classifier returns to the sand).

Combined feeder, which consists of a combination of drum and spiral feeders. It can feed dry ore and feed wet material (return sand from classifier), which is often used in the first stage of closed-circuit grinding. In addition, since the joint feeder is easy to add steel balls to the ball mill, it is also used in the second section of the grinding belt. Relatively speaking, the joint feeder application is more extensive.

Plastic Injection Control Handle

The handle is a kind of mechanical accessory, which is convenient for workers to operate machinery. Mechanical accessories industry handles have two main types of materials are plastic, steel parts. Steel parts are machined by machine and differentiated from castings. The plastic handle is divided into thermoset plastic and thermoplastic plastic.
According to handle material is divided into: bakelite handle, iron handle, zinc alloy handle, steel handle and so on.
According to the working performance of the handle, it can be divided into: handle, turning handle, locking handle, adjustable handle, folding handle, handle sleeve, handle lever, handle seat, swinging handle, three-ball handle, etc.
According to the handle shape can be divided into: handle, straight handle, turn the handle of surface, turn the handle of the little turn the handle, the steel chrome plated handle, handle the seventh, peulthai the (adjustable set handle), folding handle, long handle, the handle cover, oval handle cover, handle the ball, rod, joystick, disc handle, lock handle, positioning controller, three goals, positioning joystick, ball head, oblique cone column joystick, etc.
