Feeding mechanism of crusher

Abstract

The present invention relates to crusher technology, and is especially feeding mechanism of crusher. The feeding mechanism includes one feed port with tilted tangent flow passage comprising casing and sliding plate, feed baffle capable of masking the tangent flow passage, horizontal cylindrical casing in the end of the tangent flow passage possessing two axial opening separately to the end of the tangent flow passage and the crushing chamber; and one feeding wheel inside the cylindrical casing and comprising central shaft for power input and radial blades on the shaft. During operation, the central shaft rotates in homogeneous speed for homogeneous feeding to form thin-layer linear feeding flow, and the material may obtain high kinetic energy for fast crushing. The present invention may be applied in hammer crusher.

Description

technical field [0001] The invention relates to a feeding mechanism of grain and feed machinery, in particular to a feeding device of a pulverizer. Background technique [0002] At present, there is a feeding mechanism of a pulverizer, which includes a feed port, and a tangential flow channel composed of a shell and a slide plate and facing to both sides of the crushing chamber is arranged in the feed port, and the mouth of the tangential flow channel is provided with The feeding baffle can cover the tangential flow channel. When working, the material enters from the feeding port. The feeding baffle can be opened and closed. Changing the position of the feeding baffle can make the material flow to one side or the other side of the crushing chamber , the material enters the crushing chamber tangentially along the crushing chamber after passing through the tangential flow channel, and the material is crushed under the impact of the hammer. In the prior art, there is also an i...

Problems solved by technology

Because the hammers at the same position are on the same line when the hammers rotate at high speed, if the time to reach the material in the crushing chamber is different, the time and amount of material that the hammers on one line contact are different. When the blades are just in contact, the relative speed is the largest, and the hammer blades can easily crush the material. At this time, the wear of the hammer blades is also the largest. Uneven feeding and different contact between the material and the hammer blades will cause uneven wear of the hammer blades; at the same time, The contact time between the material and the hammer is different, and it is easy to cause a batch of materials to fall into the crushing chamber and lose a chance of a strong impact crushing, prolonging the crushing time; in addition, the existing feeding method can give the material kinetic energy Increase the relative speed difference between the material and the hammer to obtain greater crushing kinetic energy, and the crushing effect is relatively poor

At the same time, due to the lack of pressure difference compensation in the existing feeding method, the material is easy to form a bridge arch and cannot be fed;
