I. Description

The ZSJ dual rotor sand making machine developed by Dingli integrates three advanced international technologies and adopts two outstanding achievements of domestic industry. It dramatically solves the drawbacks of single-rotor sand maker such as large energy consumption and poor shape of finished materials.

II. Structure

It is widely applied in stone, cement and various metallurgical slag industries for crushing and shaping soft and medium aggregates.

The structure includes a feeding port, a hammer, a rotor, a crushing chamber, a inspection and observation window, a grate plate with adjustable discharge size, and a material distribution device.

III. Operation Principle

ZSJ sand maker is mainly composed of the body, crushing plate, upper and lower rotors, pendulum, rotary drive, sieve and other parts. During operation, with relative movement of the two rotors, the aggregates in the crushing cavity are firstly hit and crushed by the hammers of the first rotor, then rushed to the second rotor after obtaining a certain momentum. Since the second rotor moves in the opposite direction of flying materials, its speed of striking the aggregates is equal to superposition of two velocities. Through such cycles of repeated striking, the aggregates are discharged from the gap of grid.

Top Four Features

Two feeding ports

Two feed openings ensure the raw materials are simultaneously distributed in the best crushing position of the two rotors.

Two rotors

The aggregate materials are thrown by the two rotors in a tangential direction, so the machine has large reduction ratio and high yield.

Stone breaks stone

Repeated collisions facilitate self-shattering of the stone in the crushing cavity and reduce the abrasion of the hammers and the wear parts.

Adjustable grate gap

Adjustable grid gap design enables customers to obtain the finished materials with required particle size distribution and fineness modulus.

Top Six Advantages

Improved Efficiency: Opening and closing of ZSJ dual rotor shell are operated in the center of the rotor. Convenience in replacing the rotors, grids and the wear parts, it greatly enhances the work efficiency and reduces the labor intensity of maintenance workers.

Steady Operation: The rubber spring is adopted in the overall structure of grid for damping, which effectively ensures the smooth operation of the equipment.

Hydraulic Device: With quick connector adopted for the hydraulic component, you can always move the pump station away from dust area to extend service life of the pump station.

Easy Maintenance: The manual observation door under the two rotors is used for quick inspecting & cleaning the clogged aggregates and repairing grid plate. Timely clean the materials and inspect the parts so as to reduce repair for the machine.

Multiple Functions: The machine has a preferred model for commercial concrete mixing plant. It completely changes the backward production technology which shall need a few groups of crushers. Thus the investment and production site can be effectively saved.

Reasonable Gradation: The aggregates crushed by the machine have excellent shape, continuous gradation, and adjustable fineness modulus. The crushed sand can be as good as natural sand in terms of shape and size.
