Over Flow Type Ball Mill Machine
【What’s the over flow ball mill machine?】Overflow type ball mill, the material level of the ball mill is higher than the discharge port, and the automatic overflow is called overflow type. The overflow ore discharge is more intelligent. It mainly uses the gravity of the pulp to discharge the ore. a certain height difference is formed between the feed port and the discharge port, and the ground qualified pulp continues to flow to the discharge port. When the discharge volume is large, the pulp will overflow and discharge when it reaches a certain height and fall into the finished product collection device. Overflow discharging is not only intelligent, but also the ground pulp will be discharged naturally, which also saves energy consumption.
【Feature of Over Flow ball mill machine】
Low Energy Consumption- overflow ball mills feature low starting current and short starting time. The power consumption of normal operation is 20% – 30% lower than that of other ball mills.
High Quality & Small Maintenance-The quill shaft is made of steel casting, the rotary gear is processed by casting hobbing, and the cylinder is inlaid with wear-resistant lining plates.
Low Cost- Our overflow ball mills have a reasonable price, less auxiliary equipment, and a simple material feeding device.
Steady Running- The use of hydrostatic and hydrodynamic bearing makes the operation stable and reliable.

Over Flow Ball Mill Structure

【Over Flow Ball Mill Parts】The overflow ball mill is composed of cylinder, end cover, main bearing, quill shaft, transmission device, feeding device, manhole, pinion device, lining plate, etc.
【Working Principle of Over flow ball mill】The main component of wet overflow ball mill is a cylinder with small diameter and large length, which is supported by rolling bearings and rotates slowly through transmission machinery. Materials are fed from the feeding end of the cylinder. In the cylinder, due to the dropping impact and self grinding of steel balls and ore itself, materials are crushed. Due to the continuous feeding of materials, the pressure causes the materials in the cylinder to move from the feeding end to the discharge end, and the pulp flows out by itself higher than the lower edge of the hollow shaft at the discharge end. The hollow shaft is equipped with counter spiral blades, which can return the overflow steel balls and coarse ore blocks to the mill.
