FFQThe rotor diameter of the series hammer crusher is generally less than 500mm, the mesh aperture is between 0.5-25mm, and the power is generally less than 30kw. The rotor diameter of the PSJ series hammer crusher is greater than 500mm, and the power configuration is above 30kw. The PC series crusher is divided into two types: single-stage hammer crusher, model PC series, and double tap hammer crusher, model SCF series. Our factory can design the most reasonable crusher for customers according to their different needs.
First, let's introduce the single-stage hammer crusher:

·Hammer crusherSuitable for crushing medium hardness materials such as limestone, slag, coke, coal, etc. in industrial sectors such as cement, chemical, power, metallurgy, etc. The hammer crusher is a type of crusher that directly crushes materials with a maximum particle size of 600-1800 millimeters to 25 or below. The FFQ series hammer crusher can crush materials to below 0.5mm, but the feed size is generally less than 50mm..

The hammer crusher uses a high-speed rotating hammer head to impact the ore. When the ore enters the crushing chamber, it is crushed by the impact of the high-speed rotating hammer head. At the same time, the ore gains kinetic energy during the impact process and rushes towards the crushing plate and sieve bar at high speed for further crushing. Performance characteristics of hammer crusher:
The hammer crusher has a compact structure, reasonable layout, easy installation, good maintainability, and easy operation. Especially with excellent adaptability to the layout of cement production processes. Save process layout space; It has special structural characteristics, such as the 'large breaking ratio' for material crushing. Hammer crushers are divided into two types: ordinary hammer crushers and ring hammer crushers. Ring hammer crushers are generally widely used in industries such as coal and coke crushing.

Hammer crusherMain technical parameters:

·Equivalent to two hammers breaking into one, combined into a reasonable whole, two sets of rotors are used in series, with the following characteristics:

1、 Double rotor upper and lower two-stage crushing

The two sets of rotors connected in series enable the material that has been crushed by the hammer head of the upper rotor to be immediately crushed again by the hammer head of the lower rotor that rotates rapidly. The materials in the inner cavity collide with each other at high speed and are crushed, achieving the effect of hammer powder and material powder, and are directly discharged.

2、 No sieve bottom, high humidity material, never clogging

Traditional crushers with grate screen plates are not suitable for raw materials with a moisture content higher than 8%. When the moisture content of the raw materials is higher than 10%, serious blockage is prone to occur, causing the hammer head to not rotate, the material to not be discharged, and even burning out the motor, seriously affecting production.

The design of this machine does not have a sieve bottom, and there is no strict requirement for the moisture content of the material. There is no problem of clogging the sieve plate, and there is no problem of fine powder not being discharged in a timely manner or repeated crushing. Therefore, the crushing efficiency is high and there is no ineffective wear of the hammer head.

IIIUnique bidirectional gap adjustment technology

After the wear of the hammerhead, the gap between the hammerhead and the lining plate becomes larger and the particle size becomes coarser. The hammerhead can be moved outward from the center to narrow the gap between the hammerhead and the lining plate and continue to be used. You can also adjust the gap by pushing the lining plate from the outside to the inside to control the particle size of the discharge.

4The device is equipped with a counterweight balance wheel, which runs smoothly with high inertia and saves energy20%

Both upper and lower sets of rotor shaft ends are equipped with flywheels, which can adjust the periodic speed fluctuations during operation, making it run evenly and smoothly, increasing rotational inertia, overcoming motion resistance, and saving more than 20% electricity.

5Centralized lubrication system, non-stop oil injection, convenient and fast

Double stage crusher lubrication system, changing the traditional way of adding lubricating oil to the grease nipple and oil cup; Centralized oil distribution pump configuration, one-step operation, multiple oil supply channels; The whole machine can simultaneously lubricate all bearings with lubricating oil at any time while the machine is in operation, which is convenient and fast. Due to the fully enclosed oil circuit, it can also prevent dust from entering and damaging the bearings.

VIHydraulic automatic starter housing

The hydraulic opening and closing device only requires one person to easily open and close the casing, which is not only lightweight, fast, safe and reliable, but also easy to maintain.

7、 High output, low noise, and good crushing effect.

8、 Solved the problem of rapid wear of the hammer head and lining plate in old-fashioned crushers.

9、 Low price, suitable for private and small businesses to purchase and use.

10、 Thoroughly solved the problem of high moisture content in materials that cannot be crushed.
