The heavy hammer crusher is an important member of the crushing equipment. With its unique performance characteristics and wide range of applications, it plays an important role in many industries such as mining, cement, coal, metallurgy, and building materials. The following is a detailed introduction to the heavy hammer crusher.

1. Definition and working principle

The heavy hammer crusher, also known as the heavy hammer crusher, is a device that uses a high-speed rotating hammer to impact, crush and grind materials. Its working principle is simple and efficient: the motor drives the rotor to rotate at high speed, and the hammer on the rotor then strikes and crushes the material entering the crushing chamber. After being impacted by the hammer, the material will be further thrown to the wall plate or impact plate of the crushing chamber, and will be impacted and crushed by the hammer again until it reaches the required particle size. Finally, the crushed material is discharged from the crushing chamber through the discharge port and enters the next processing stage or collection.

2. Performance characteristics

a. Efficient fine crushing: The heavy hammer crusher integrates stone crushing and stone shaping, with large feed particle size, small discharge particle size, and high crushing efficiency.

b. Large crushing ratio: The heavy weight of the hammer and the high rotor speed make the equipment have a large crushing ratio and output.

c. Flexible adjustment: The discharge particle size is adjustable and the adjustment range is wide. The gap between the hammer and the liner can be adjusted according to user needs to change the discharge particle size.

d. Strong adaptability: It can handle materials with high water content without blocking, and can crush a variety of medium hardness and brittle materials.

e. Wear-resistant and durable: The hammer is made of high-chromium alloy material, with high tensile strength and wear resistance, and long service life.

f. Simple structure: The equipment has a simple structure, convenient maintenance, and easy replacement of wearing parts, which reduces maintenance costs.

3. Application scope

Heavy hammer crusher is widely used in environmental protection, mining, cement, coal, metallurgy, building materials and other industries. Specifically, it can be used to crush limestone, coal, iron ore and other materials, and provide high-quality sand and gravel aggregates for infrastructure construction such as highways, railways, water conservancy, airports, etc. In addition, heavy hammer crusher can also be used to make industrial raw materials such as abrasives, refractory materials, cement, etc.

4. Equipment structure and composition

The heavy hammer crusher is mainly composed of a frame, a transmission device, a rotor, a hammer head, an impact lining plate, a screen plate, etc.

a. Frame: It is the main supporting part of the crusher, consisting of an upper body, a lower body, two side wall plates and a bearing seat.

b. Transmission device: It is mainly composed of an electric motor, an elastic coupling and a main shaft, and is used to drive the rotor to rotate at high speed.

c. Rotor: It is the main working part of the crusher, consisting of a main shaft, a hammer disc, a pin shaft and a hammer head, etc.

d. Hammer head: It is the main force for crushing materials, fixed on the hammer disc by a pin shaft, and moves with the rotation of the rotor.

e. Impact lining plate: It is used to withstand the impact and grinding of materials, and has excellent wear resistance and impact resistance.

f. Screen plate: It is used to screen the crushed materials so that the materials that meet the particle size requirements can be discharged from the crushing chamber through the screen holes.

PS: The heavy hammer crusher plays an important role in many industries with its high-efficiency fine crushing, large crushing ratio, flexible adjustment and strong adaptability. With the continuous advancement and innovation of technology, the heavy hammer crusher will further enhance its performance and application scope, providing more efficient and reliable crushing solutions for more fields.
