Industrial Grinders, N.V. has decided to start manufacturing and selling plastic rings for use in their machines. Currently, they manufacture and sell steel rings, along with the machines they also manufacture and sell through another division of the company. They recently discovered that a competitor in France will now be selling plastic rings. These plastic rings will serve the same purpose as the steel rings Industrial Grinders manufactures. However, they cost less to manufacture and they last longer. Management has decided that Industrial Grinders will now start to manufacture plastic rings. Lawrence Bridgeman, General Manager of the German plant, is tasked with deciding whether or not he should scrap a large quantity of steel, manufacture and sell both steel and plastic rings or continue to manufacture and sell steel until their stock of steel is depleted.…
Molybdenum ore ball mill ApplicationBall mill, a type of Grinding Mill, is a cylinder-shaped device used to grind materials like ores, chemicals, ceramic raw materials and paints. The ball mills are the key milling equipment after material has been crushed. It is divided into two rubbing way, the dry and the wet Ball mills mainly composed of charging and discharging, cyclone and rotation parts (like redactor, minor rotation gear, motor, electric machine, etc.)Molybdenum ore ball mill PrincipleThe ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.Specifications of Molybdenum ore ball mill Modelcylinder speed(r/min)Ball Weight(t)feed particle size(mm)Give Makings Size(mm)Output(t/h)motor power(kw)Total weight(T)900×180036~381.5≤200.075-0.890.65-218.54.6900×3000362.7≤200.075-0.891.1-3.5225.61200×2400363≤250.075-0.61.Flotation Machine5-4.830121200×3000363.5≤250.074-0.41.6-53712.81200×450032.45≤250.074-0.Flotation…

The material goes to the first hopper after the spiralling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.…
A Ball Mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial Ball Mills can operate continuously fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mills are also…

When the ball mill works, motor and speed reducer transmit torque force to big and small gears of ball mill, so the barrel rotates. When the barrel rotates, Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely, so materials in the barrel are impacted. Grinding media mixing with materials impact and grind materials continuously. The grinding media and materials impact and grind each other when the ball mill rotates continuously. The final product will be discharged from outlet when it meets the request, so the grinding process is finished application range, simple structure and convenient maintenance.…
GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually, the process is as much a cutting action as drilling, milling, and lathe turning.…
