sun ball mill particle size control

what'sthe difference between sag mill and ball mill

The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s crushing ratio is smaller

(pdf) design and fabrication of miniball mill

This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2. The variation of a with ball diameter was found to be of the form a = k2/d1.5

overflow vs grate discharge ballormill- why retrofit

Apr 24, 2018 · The discharge grates are not to control the size of particle discharged, but merely to retain the grinding balls within the mill, provide the full discharge area required, and form the steep gradient between the feed entrance and product discharge. Example of Plant Capacity Gains

what particle size range does ball mill grinding produce?

Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around

supervisory expert control for ball mill grinding circuits

Apr 01, 2008 · Stable control of particle size in ball mill grinding circuits is of great importance for the recovery of the valuable minerals, and the maximization of mill capacity is another main consideration in concentration plants. A supervisory expert control strategy is proposed to control product particle size and to improve fresh ore feed tonnage in

ball mill - an overview | sciencedirect topics

The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones

planetary ball mill pm 100 - retsch - highest fineness

Size reduction principle: impact, friction: Material feed size* 10 mm: Final fineness* 1 µm, for colloidal grinding : 0.1 µmBatch size / feed quantity* max. 1 x 220 ml, max. 2 x 20 ml with stacked grinding jars: No. of grinding stations: 1: Speed ratio: 1 : -2: Sun wheel speed: 100 - 650 min-1: Effective sun wheel diameter: 141 mm: G-force: 33.3 g: Type of grinding jars

intelligent optimalcontrolsystem forball millgrinding

Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively, while guaranteeing producing safely and stably. The grinding process is essentially a multi-input multi-output system (MIMO) with large inertia, strong coupling and uncertainty characteristics
