A screening and stacking machine is a vibrating screening mechanical equipment that uses the relative motion between bulk materials and the screen surface to allow some particles to pass through the screen holes, and divides materials such as sand, gravel, and crushed stone into different levels according to particle size. The screening process is generally continuous. After the screened raw materials are fed to the screening machine (referred to as the sieve), materials smaller than the sieve size pass through the sieve holes, which are called undersized products; Materials larger than the size of the sieve are continuously discharged from the sieve surface, known as products on the sieve.

         At present, the company can design and manufacture through and turn back dumper unloading systems suitable for different site conditions, including "O" type, "C" type turning and side turning dumpers, which can dump single and double open cars at one time, and can upgrade the old dumpers. The company's products have advanced electrical and hydraulic control level, such as unloading process automation control and fault self diagnosis.
