China-2013-New-Type-Small-Scale-Gold-Processing-Hammer-Crusher-HGS400-600-

Hammer crusher is primary crushing equipment which could crush the materials from 600-1800mm to 20mm or smaller in once. It is applied to cement, chemicals, electric power, metallurgy and so on industries middle hardness materials such as limestone, slag, carbon coke, coal and so on materials middling and fine crushing.

This series hammer crusher is small volume, light, simple structure, easy operation and maintenance, high crushing ratio, low over-crushing ratio, average final product particle size, high capacity and so on characters. It is applied to crush brittleness, middle hardness, strength of pressure-resistant is 150MPa each kinds of materials. The hammer crusher feature hammer head adopt new craftsmanship casting, wear-resistant and impact-resistant.

Hammer crusher's features
1). Hammer head, casting with new craftsmanship, wear-resistant and impact-resistant.
2). Adjustable of required particle size as customer requirement
3). Body of machine structure is covered, which solved problem of powder pollution and body ash leaking in crushing plant.
4). Beautiful appearance, compact structure, few consumable part, convenient maintenance and so on advantages

Hammer crusher working principle
Hammer crusher is crushing equipment utilize impact energy to crush materials. When the chine works, with the driving of motor, rotator rotate fast, materials enter the hammer area, hit with the hammer board, then it will throw to impact device for further crushing, and later whipped back to the hammer area to repeat crushing, repeat this procedure, the material from big size to small size enter 1, 2 and 3 impact mouth repeat crushing until its reach your required particle size and discharge from output opening. To adjust the spacing between impact frame and rotor can change the discharging size and shape of the materials.

Slewing Mechanism and Spare Parts

A slewing mechanism is an essential component of a Tower Crane that allows it to rotate horizontally. It enables the crane to reach different areas of a construction site without having to move the entire structure.

The slewing mechanism typically consists of the following components:

1. Slewing Ring: The slewing ring is a large circular bearing that supports the entire weight of the crane and allows it to rotate. It is usually located at the base of the crane and is designed to withstand heavy loads and provide smooth rotation.

2. Slewing Motor: The slewing motor is responsible for providing the necessary power to rotate the crane. It is connected to the slewing ring and is controlled by the crane operator.

3. Gear Mechanism: The gear mechanism consists of a set of gears that transmit the power from the slewing motor to the slewing ring. It ensures smooth and controlled rotation of the crane.

4. Brake System: The brake system is an important safety feature of the slewing mechanism. It is designed to hold the crane in place and prevent any unintended rotation when the crane is not in operation.

5. Control System: The control system allows the crane operator to control the rotation of the crane. It typically includes joysticks or buttons that enable the operator to start, stop, and control the speed and direction of rotation.

Overall, the slewing mechanism plays a crucial role in the functionality and versatility of a tower crane. It allows the crane to move horizontally, reach different areas of a construction site, and perform various lifting tasks efficiently.
