Sand Crusher

SZJ Series Sand Making Machine




Application areas:Double-rotor sand making machines are widely used in the crushing and sand making of materials in mining, quarries, building materials, commercial mixing stations and other fields.
Applicable materials:Double-rotor sand making machine, also called hammer sand making machine, integrates fine crushing and shaping, and is suitable for crushing and making sand making operations of limestone, gangue, shale and other raw materials.


The XGN-SZJ series dual-rotor sand-making machine is fine and plastic, which can be purely out of boutique sand, but also for sand and gravel,it can effectively save the investment cost of equipment,and have many significant advantages such as grade cooperation and fine degrees modulus adjustment.


High yield and excellent granularity

The double-rotor structure has more kinetic energy, and the output of a single machine is large; The principle of "stone beating stones" effectively reduces components such as hammer head, wear -resistant guardian and other components, and extend the service life of the equipment; the finished product is round and the grade is continuous.

Convenient maintenance

Equipped with observation doors around the equipment, it is convenient to observe the internal conditions of the equipment at any time;full hydraulic opening, quick and convenient replacement and maintenance of internal parts.

wear -resistant and durable

The rotor is equipped with a high manganese and high chromium protective cover, which increases the lifespan by 30%;the hammer shaft hole is equipped with a tungsten alloy steel sleeve, which is wear-resistant and impact-resistant.

Customized on demand

THE grate bar can be customized according to needs, grate bar with round holes and long bar can choose;the gap between the grate bar and the hammer head can be adjusted flexibly, which fully ensures the crushing efficiency of the hammer head.


SZJ Series Sand Making Machine WORKING PRINCIPLE
Driven by the dual motor, the two sets of rotors connected to each other at the same time were rotated at the same time,after the materials were crushed by the superior rotor in the machine, the hammer head of the lower -level rotor that rotated quickly was broken again, the inner cavity material collides with each other quickly, crushing each other, after many cycles, the ingredients that reach the qualified granularity are discharged through the material port controlled by the grate bars.
