The goods can be delivered on DAP or DDP-customer’s warehouse basis in full compliance with all the relevant regulations and requirements that are applicable on the Russian market.
Our company has its own certified specialists who will carry out installation supervision and commissioning of the delivered equipment, as well as further guarantee and post-guarantee maintenance of edge runner mills. They will also provide necessary training and guidance for the customer’s personnel.
Edge runner mills (also referred as edge runners) are the grinding machine. Their main components are bowl and two (or three) grindstones making the complicated motions around horizontal and vertical axes. Edge-runners grind a material by crushing and grinding the pieces by massive grindstones, which roll along cast iron bowl.
There are two main types of edge-runners:
Grindstones of both edge-runners are rotated around the horizontal axis. Edge-runners with fixed bowl and moving grindstones are used to grind all-lump materials, i.e. those that were not foreground. Edge-runners with rotating bowl and fixed grindstones are used to grind preliminary crushed material.
Considering that a sufficiently large centrifugal force occurs during grindstones rotation around the axis, for its reduction you should decrease the number of bowl rotations or grindstones themselves. This consequently reduces edge-runners performance.
Edge-runners of the second type, as compared with the first ones have a slightly larger number of rotations, respectively, together with higher performance, but such edge-runners require high-powered center plate supports development.
Performance and power consumption
Theoretically, edge-runners performance can be calculated assuming that all pieces of material ground are of spherical shape.
Under such conditions you can easily calculate the theoretical number of material pieces (?), which runners can grind per hour:
Z = [(2πrсрb)/d²]·60ni
Where:
rср – grindstones rotation average radius, m;
b – grindstones width, m;
d – material pieces diameter, m;
n – edge-runners rotations number, min-1;
i – grindstones number.
In practice, only about 2 percent of theoretically calculated volume of material is ground per one grindstones rotation with a given grinding degree.
The work spent for material grinding in edge-runners can be calculated, when summarizing the friction, rolling and sliding work.
Edge-runners design
Today edge-runners are of very different designs. Cast iron bowls of these machines can be either solid or composite and cast iron grindstones located in bowl have external steel compressive rings. Bowl bottom is covered with steel plates-grate bars. Materials grinding degree depends on gaps size between these grate bars. The working parts - grindstones may be both freely mounted on axes and rigidly connected with them.
In order to avoid edge-runners sudden breakdown due to excessively large and hard material pieces, their axes should be hoisting or crank shaped (in machines with grindstones rigidly fixed on axis). The axes in edge-runners with hoisting axes rotating inside the box can be moved in a vertical plane in it. Edge-runners’ shaft is equipped with ploughs that move material pieces from the center to bowl edge, as well as from the bowl periphery to the center. This is exactly why the milled material is evenly distributed over the bowl surface, and timely removed after the grinding.
Edge-runners are driven by motor via the gearbox and bevel gear drive, which can be located either over cast iron bowl or directly beneath it.
Machines with a fixed bowl can be of two types - light or heavy. They differ from each other by grindstones weight and rotations number. Low-speed edge-runners of light type as a rule make 8 - 15 rotations per minute and have a fairly large rotation radius at relatively small rim width, because of which the abrading force is very small. High-speed edge-runners are primarily equipped with top drive.
Edge-runners with a rotating bowl have several advantages over machines with a fixed bowl, namely:
1) their grindstones have more simple but equally more reliable attachment;
2) grindstones are not affected by centrifugal forces;
3) ground material discharge is much simplified.
Let us consider an example of such machine design. The grindstones in machine bowl, rotating by drive are moved due to friction and each of which also rotates around its horizontal axis. Ground material is discharged over bowl board by means of a special device - plough.
Such device with two grindstones (edge-runners) is used since the mid-19th century, therefore, probably deemed the oldest grinding device of such type. This machine operates as a roller mill. Edge-runner mill is a unit with fixed bowl, inside which there are two, slowly rotating heavy edge-runners. Also this device can be equipped with fixed edge-runners.
When rotating the edge-runners represent two massive grindstones, which bly compress and mill material pieces charged into machine bowl from above on center. Ground product leaves machine bowl along its perimeter. Ground material is continually raked off to the bowl center with a flat bottom by co-rotating scrapers, thereby repeatedly passing under the grindstones, before completely leaving the unit.
