Fine crusher

Absorb foreign advanced technology, energy saving, strong usability

The fine crusher is a multi-functional new type of fine crusher that integrates fine crushing and sand making, designed by our company according to the needs of users and combined with the advantages of foreign crushing technology. The fine crusher replaces some of the functions of the sand making machine, and is suitable for materials with compressive strength not higher than 150MPa and surface moisture not exceeding 10% with moderate abrasiveness or less, especially suitable for making abrasives, refractory materials, cement, steel sand, The fine crushing and medium crushing of various hard and brittle materials such as quartz sand can save 50% energy compared with the traditional fine crushing sand making machine.

Performance characteristics

01Reliable operation

The equipment has stable and reliable operation performance, small discharge particle size, uniform particle shape, large production capacity and long hammer life.

02Stable discharge

High linear speed, wear-resistant parts material, body structure, grate plate design, and the influence of rigid hard extrusion and crushing have fully realized the effective control of the long-term stability of the discharge particle size.

03Low investment, high return

The process is simplified, the structure is simple, the maintenance is convenient, and it has the function of sand making and shaping.

04High degree of automation

With hydraulic lock and hydraulic adjustment functions, as well as over-iron release and cavity cleaning functions. The hydraulic system version and lubrication system it is equipped with can ensure the safe and normal operation of the equipment, especially the hydraulic system can control the push cylinder to adjust the size of the discharge port.

Working principle

When the PXJ fine crusher is working, the material enters the cavity from the feeding port in turn, and falls on the high-speed rotating movable hammer head. After the action between the hammer and the counterattack plate, the material is initially crushed. After the material has been repeatedly hammered and counterattacked with high frequency, it will accumulate on the middle partition plate, slide down, fall on the material throwing plate of the high-speed rotating lower rotor, and be thrown to the counterattack plate at high speed to collide, fall and pass through. The mobile blow hammer is forced to counterattack, crush and grind. The ultra-fine effect is achieved after the material has undergone multiple composite crushing, scouring and grinding, and then discharged through the discharge port.
