Condition: used, functionality: fully functional, Foundry factory for sale, Property includes 15 buildings, 6 hectares of land.
Located at the Karhula industrial site next to the city of Kotka in southeastern Finland,
Karhulan Valimo was founded in the 1880βs. In 1902, the foundry was merged with a wood
grindery, glass factory, brick factory and engineering works to form the Karhula Oy. In 1915
the Karhula Factories were sold to AhlstrΓΆm Corporation.
The current Foundry was built in 1960 and in 2000 AhlstrΓΆm sold the foundry to Sulzer
Pumps Finland.
In 2016 Sulzer Pumps decided to close the foundry and it was sold to Karhulan Foundry
Oy, which was unfortunately declared bankrupt in March 2021. Throughout its history, the
Ppodeuxmt Tjpfx Am Tow
foundry has been known of been able to produce highly demanding castings particularly in
high alloyed steels.
In 2022 Karhu Assets Oy bought the facilities and machinery of the foundry. Most of the
equipment in the fettling shop has already been sold, while most of the machinery in the
moulding department and meltshop are intact and available.
All heat treatment furnaces, a total of 10 units, are in place and available for sale.
Welcome to visit on the site!
The equipment is located in Kotka, 48600, Finland, and is sold EXW Kotka in its current condition.

Ball mill for powder and mining plant
Mingyuan Ball Mill For Fine PowderPowder grinding mill for coal, silica
Call
Condition: new, functionality: fully functional, power: 55 kW (74.78 HP), Year of construction: 2026, Ball Mill for Powder and Mining Plant: Structure, Function, and Technical Details
A ball mill is a key grinding machine widely used in mining, metallurgy, cement, chemical, and powder-making industries. It is designed to grind various ores and other materials into fine powder through impact and attrition between steel balls and the material inside a rotating cylindrical shell. In mining plants, ball mills are essential for ore beneficiation, preparing materials for flotation, magnetic separation, or leaching processes. In powder production, they ensure uniform particle size and high surface area for further processing.
Working Principle
The ball mill operates on a simple yet effective principle: as the cylindrical shell rotates around its horizontal axis, the grinding media (steel or ceramic balls) are lifted along the inner wall by centrifugal force and friction. When they reach a certain height, they fall freely, striking and grinding the material below. This repeated motion causes both impact and abrasion, reducing the material to the desired fineness. The grinding process can be performed in dry or wet conditions depending on the application.
Structural Composition
A standard ball mill consists of several main components:
Feeding part: Equipped with a feeder or screw conveyor to ensure uniform material input.
Discharging part: Can be grate type or overflow type, depending on the discharge method.
Rotating part: The cylindrical shell made of steel plates, lined with wear-resistant liners.
Transmission system: Includes motor, reducer, small transmission gear, and electrical control.
Grinding media: Steel balls or ceramic balls of different diameters for efficient grinding.
The internal liner design and ball size distribution are optimized to achieve maximum grinding efficiency and minimal energy consumption.

Discharge size: 0.074β0.4 mm
Capacity: 0.65β615 t/h (depending on model and material hardness)
Cylinder speed: 18β38 r/min
Power: 18.5β4500 kW
Liner material: High manganese steel, rubber, or alloy steel
Grinding media load: 30β45% of cylinder volume
Operating Modes:
Dry grinding: Suitable for materials that must remain moisture-free, such as cement clinker, limestone, and quartz.
Wet grinding: Common in ore beneficiation, where water or slurry improves grinding efficiency and particle uniformity.
Application in Mining Plants
In mining operations, ball mills are used after crushing to further reduce ore size and liberate valuable minerals. They are integrated into grinding circuits with classifiers, hydrocyclones, and flotation systems. The ground material is classified by size, and oversized particles are returned to the mill for regrinding. This closed-circuit system ensures consistent product fineness and efficient energy use.
Common Applications:
Gold, copper, iron, and zinc ore grinding
Cement clinker and slag processing
Silicate and ceramic powder production
Coal and mineral powder preparation
Conclusion
A ball mill is an indispensable piece of equipment in both powder production and mining beneficiation plants. Its ability to grind materials into fine, uniform particles makes it vital for downstream processes such as flotation, sintering, and chemical reactions.

## What Is an Ore Beneficiation Plant?
An ore beneficiation plant is a facility where raw ore is processed to improve its quality and increase the concentration of valuable minerals. The plant typically includes several stages of processing:
1. Crushing: The raw ore is reduced in size to allow for more efficient downstream processing.
2. Grinding: Further size reduction to liberate the valuable minerals from the waste material.
3. Classifying: Separation of the ore into different size fractions using screening and hydrocyclones.
4. Separation: Employing various physical processes such as magnetic separation, flotation, or gravity separation to concentrate the valuable minerals.
Psdpeq Nw Uqjfx Am Tepw
5. Dewatering: Removal of excess water to prepare the concentrate for further processing or shipping.
This integrated process not only boosts the metal content but also minimizes waste, thereby improving overall cost efficiency and environmental sustainability.

In mining operations, ball mills are used after crushing to further reduce ore size and liberate valuable minerals. They are integrated into grinding circuits with classifiers, hydrocyclones, and flotation systems. The ground material is classified by size, and oversized particles are returned to the mill for regrinding. This closed-circuit system ensures consistent product fineness and efficient energy use.
In fine powder production, ball mills are used to produce materials such as silicate, ceramic powder, refractory materials, and chemical raw materials. The uniform particle size achieved by ball milling enhances product quality and performance in downstream applications.
Conclusion
A ball mill is an indispensable piece of equipment for both mining and fine powder making. Its ability to grind materials into fine, uniform particles makes it vital for ore beneficiation and industrial powder production. With flexible configurations, high efficiency, and reliable operation, modern ball mills provide a cost-effective and energy-efficient solution for large-scale grinding, ensuring consistent quality and productivity across diverse applications.
