A basket mill is basically for grinding grains and other materials into flour or meal. The mills were driven first by horses, although the Industrial Revolution saw the introduction of clockwork motors. Basket mills were once common in North America and Europe to produce flour for breadmaking - 60% of all bread sold in 1910 contained ground grain produced with a basket mill. Basket mills may also be used to process oats, corn, or poppy seeds into meal; wheat bran; quinoa; soybeans; sunflower seeds; hemp seed meal, etc.
What is a lab basket mill?
Lab basket mill is applicable for grinding raw material, and it can be widely used in the industry. The lab basket mill can crush many kinds of ores, such as feldspar, calcite, talc, kaolin, wollastonite, barite, and so on. The working principle of the lab basket mill is that the motor drives the eccentric roller to rotate continuously through the belt transmission pulley at the top of the mill. The material will then be ground by a rotating gear wheel that has many teeth. The energy will be transmitted from eccentric roller to gear-wheel through gears inside the mill to drive rotating gear-wheel, which consists of a series of blades evenly arranged around a disk or circular plate with holes. The grinding material will be ground by rotating gears. To enhance the duration, belt tension needs to be adjusted regularly. The lab basket mill is widely used in applications like metallurgy, mining, oil and gas production, and chemicals.
Lab Basket Mill
The lab basket mill mainly consists of a grinding mill, cage, and motor. The material to be ground is put into the grinding mill by workers and the material does not enter the crate because of a safety protection device (the door of the grinding mill is closed), then revolving gears will take away energy from the eccentric roller to spin. And then blades will divide and grind materials simultaneously, and then the material will be collected by a belt conveyor. The motor drives the mill, and the big gear wheel drives the gear wheel through belts.

Operation of basket mill
The mills consist of three sub-assemblies; the grain feeder, the grinding mechanism, and the flour hopper. The grain feeder is an elevated trough for milling grains (it is large enough to hold 75 kg of wheat). The bin or hopper, a rectangular box a few inches deep, sits on top of the trough. Permanently installed to one side is a feed screw system that feeds grain from the hopper into the turning grinding assembly. The turning grinding mechanism sends ground flour from its outlet back to a storage bin. The modern mills have been updated to use a more efficient belt feed screw.
In operation, the miller places grain in the feeder and pulls a lever or handles a crank which starts the feed screw turning. The screw pulls the grain from the hopper and pushes it into a feeding tube. The grinding mechanism is mounted on top of a pivot point, which allows it to swing out over the hopper for access, then oscillate back into place when not in use. A large metal spring arm with a moveable end engages the grinding mechanism, pushing it into contact with a stone that has been selected using an attached lever on top of the mechanism housing. As the screw pulls grain into the feeding tube, it is ground against the stone. The stone may be flat or concave, smooth or coarsely grooved. The process strips whole grains of their husks and breaks them into large pieces. Only small amounts are lost to waste between the grindstone and hopper.
The storage bin is a rectangular box with a hinged lid, which holds approximately 2/3 of a bushel (1½ US gallons, 1¾ Imperial gallons). The waste rests on top of the feeder/hopper assembly. Inside are two removable bins that can be lifted out for emptying or refilling by hand or using a small scoop.
To separate the ground grain from the husks and stray bits of stone, a wire screen is installed inside the bin. Some mills also include a tap which allows the thrash to be drained through a hose or pipe. The original hand-driven basket mills were made entirely of wood, but most modern mills are now made with stainless steel and cast iron. The mill's wood and metal components can be purchased new or second-hand from antique mill vendors and on eBay.

Difference between flour mill and basket mill
There is often some confusion between this type of grain mill and that described as a flour mill. The difference with them is that flour mills grind wheat into flour, whereas basket mills grind other grains into a meal. The two should not be confused, as the mill works very differently.
The grain for flour mills is ground using a grill that spins in a vertical cylinder through which the grain is propelled using many blades. The auger wheels are usually made of metal, while the auger blades are often made of wood. Some mills have both metal and wood components. Flour mills require more maintenance than basket mills, which run more quietly and do not need to be maintained. After grinding, the ground grain goes to a bin above to be weighed and processed further before leaving the milling area via an outlet chute for further processing or storage into cans or other containers.
