XRF Sample Preparation Machine FFGM series Grinding mil uses the suspension fork structure (FFGM-1: 6 pieces press springs, 8 pieces pull springs; FFGM-4: 8 pieces press springs,8 pieces pull springs.). Causes the Grinding mill to grinding efficiency enhancement, the noise reduces. Suspension fork structure: Increases the horizontal direction action, enhances the grinding efficiency; reduces the vertical horizontal direction action, reduces the mechanical noise. Automatically protection: The Grinding mill will stop automatically under following conditions: Power supply lack 1-phase, or current overload. The cover does not keep in place.Grinding vessel cubage: 100cc/ setTypeFFGM1T ( Frequency-conversion )FFGM1T ( Two-speed )FFGM1 PS( Single-speed )FFGM4PS( Single-speed )Charging granularity≤ 5mmDischarging granularity≤ 80umFill sample2080 gramGrinding time0999 sRoate speed1.5kwPower supplyAC 380V±10% / 50Hz, 3-phase+earthMotor300 400 r/min910 / 1400 r/min1400 r/minRated load1.6kwGrinding vessel amount14Grinding vessel cubage100cc/ setGrinding vessel materialTungsten Carbide or Chrome-SteelDimension610×550×890mm710*810*1080mmWeight280kg360kgAmbient temperature540
