Ore Processing Gold Recovery Stone / Rock Hammer Mill

Ore Processing Gold Recovery Stone / Rock Hammer Mill  Working PrincipleThe hammer mill driven by the diesel engine or electric motor is fixed on a steel frame. The main working part of the hammer mill is the rotor with the hammers. The rotor consists of the main shaft, disc, pins and hammers. The motor drives the rotor to rotate at high speed in the crushing chamber. -50 mm ore enter the crushing chamber from the top inlet with water together. The ore is comminuted by impacting, smashing, shearing and grinding caused by the hammers rotating at high speed. There is a sieve plate under the rotor. The sieve plate discharges the undersize particles and water. The coarse oversize particles are held on the sieve plate for crushing and grinding again by the hammers. Finally then the qualified particles are discharged out of the crushing chamber.                                          Features and AdvantageEasy to install, replace wear pars and operate.   Compact structure to be formed a modular plant with other equipment easily.   The hammer mill can be driven by the electric motor or diesel engine according to the customer's demand. The opening slots of the wear-resisting sieve plate are cut by the laser cutter. The aperture can be 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.5mm or 2.0mm for good gold liberation. This advantage supports the hammer mill to replace the ball mill or rod mill for the artisanal small scale gold miners to recover gold as much as possible. The material of hammers is wear-resisting alloy steel for long life and reliable running. The hammer mill works as wet grinding type to get high efficiency and more capacity.   ApplicationsThe hammer mill can crush the ores from less than 50mm to the proper size to liberate free gold fully which is suitable to recover free gold particles and nuggets by the shaking table, concentrator or sluice box.  Technical ParametersModelCapacity(t/h)Feeding Size(mm)Discharging Size(mm)Driving OptionsElectric Motor(kW)Diesel Engine(HP)200×5000.5-2
