Detailed design of jaw crusher feed hopper

Jaw crusher feed hoppers are designed to provide a steady, uniform feed of material to the crusher. They must be sized to accommodate the maximum feed rate of the crusher, and they must be constructed of materials that can withstand the wear and tear of the crushing process.

Jaw crusher feed hoppers are typically made of one of the following materials:

• Steel: Steel is a strong and durable material that can withstand the wear and tear of the crushing process. Steel is also relatively inexpensive, making it a popular choice for feed hopper construction.
• Concrete: Concrete is a strong and durable material that can withstand the wear and tear of the crushing process. Concrete is also relatively inexpensive, making it a popular choice for feed hopper construction.
• Rubber: Rubber is a flexible material that can absorb vibration and shock. Rubber is also relatively inexpensive, making it a popular choice for feed hopper construction.

The design of the jaw crusher feed hopper must also consider the following factors:

• Angle of the hopper: The angle of the hopper determines the direction of the material flow. The angle should be steep enough to prevent the material from sliding back out of the hopper, but not so steep that the material is difficult to feed into the crusher.
• Size of the hopper: The size of the hopper must be large enough to accommodate the maximum feed rate of the crusher. The hopper should also be deep enough to prevent the material from spilling over the sides.
• Shape of the hopper: The shape of the hopper should be designed to promote smooth material flow. The hopper should be free of sharp angles or corners that could cause the material to get stuck.

Design procedure

The following steps can be used to design a jaw crusher feed hopper:

1. Determine the maximum feed rate of the crusher. This information can be found in the crusher manufacturer’s specifications.
2. Select the material for the hopper. Consider the factors listed above when making your selection.
3. Determine the angle of the hopper. A good starting point is an angle of 45 degrees.
4. Determine the size of the hopper. The hopper should be large enough to accommodate the maximum feed rate of the crusher. The hopper should also be deep enough to prevent the material from spilling over the sides.
5. Design the shape of the hopper. The hopper should be free of sharp angles or corners that could cause the material to get stuck.

Jaw crusher feed hoppers are an important part of any jaw crusher operation. Careful design and construction is essential to ensure that the hopper provides a steady, uniform feed of material to the crusher.

Here are some additional tips for designing a jaw crusher feed hopper:

• Use a hopper design software program to help you with the calculations. There are several software programs available that can help you design a hopper that meets your specific needs.
• Consult with a qualified engineer or designer. An engineer or designer can help you ensure that the hopper is designed to meet all of your requirements.
