Vibrating screen is a screening equipment for sand and gravel aggregates. It has the advantages of large output and high screening efficiency, and is widely used in sand and gravel yards, mines, building materials, chemicals, water conservancy and hydro power, concrete mixing and other industries.
Compared with other screening and grading equipment, vibrating screen has many outstanding advantages, which can be called an enduring screening equipment. After the traditional shale shaker has been used for a long time, due to the impact of screening materials, the side plates of the shale shaker will be worn, thus reducing the service life of the shale shaker.
Vibrating screen have been used to separate various parts of mixtures containing multiple elements, such as a small amount of gold mixed with sediments. When shaking or vibrating, some elements of the mixture in the screen will pass through the screen, while others will remain on the top. Most modern screens vibrate due to inefficient and laborious manual operation. A basic vibrating screen can be made of ordinary materials, a motor and some electric tools.
Set the base aside, and repeat Step 1 to create another rectangle formed from 4-foot and 2-foot boards. This time, however, use the 4-foot section remaining from Step 1, and cut another board that is 8 feet long, 4 inches wide and 2 inches thick into one 4-foot section and two 2-foot sections.
Attach the completed frame to the base at an angle with an electric drill and screws, so that the middles of the 4-foot boards on the frame are screwed to the base halfway up the 4-foot upright boards. One of the 2-foot sides of the frame should be screwed to one of the 2-foot sides of the base. The frame should now be firmly attached to the base at an angle.
Cut a piece 4 feet 2 inches long from the remaining 8-foot-long, 4-inch-wide and 2-inch-thick board. Use an electric drill and screws to attach this piece directly to the base on top of the two upright boards. Position it so that it sits directly over the wire mesh.
Use a hacksaw to cut a 1/16-by-1/4-inch aluminum bar down to a length of 3 inches. Drill a hole toward one side of the bar using an electric drill with a 1/8-inch drill bit. Remove the blade from the jigsaw, and put the aluminum bar in its place with the hole facing down.
Secure the jigsaw to the board from Step 6 by screwing its base onto the board with an electric drill and screws.
Insert the top portion of an S-hook through the hole, and attach a 6-inch length of chain through the bottom half. Attach the top half on an S-hook to the bottom of the chain, then attach two 2-foot lengths of chain to the bottom half. Attach these to the chains to the two hooks on either end of the 2-foot dowel from Step 9 so that they are taut.
