A ball mill is a type of grinder used to grind and blend bulk material into QDs/nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball …
Just like a bloated stomach, if the amount of grinding exceeds the maximum capacity and discharge capacity, it will cause the mill shell to loses its grinding capacity, and that's why we call it "swollen belly".
CHAENG cement ball mill equipment can reduce energy consumption by 30% and increase the processing amount by 1520% after transformation. The cement ball mill can perform dry process production and also wet process production, moreover it can do grinding and drying at the same time.
The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...
According to the data we know, the total cost of a cement plant is estimated to be US$ 17,000 to US$ 20,000 per ton. One thing to be clear, this is just an estimation, in the real cement plant building, the cement factory cost is affected by various factors, including the significant difference in the cost of land, availability of limestone ...

What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
Using the 2.25 kg (charge) − 24 min (duration of revolution) processing parameter combination, approximately 35% of the attached mortar was removed. According to previous research, the percentage of attached mortar on the aggregate surface is approximately 45%. As a result, 77% of the total attached mortar was removed using the …
3.3.1 Cement Mill. The approach is to use a ball charge as fine as possible in the 2 nd compartment for all cement types as long as the criteria for size reduction is met in chamber 1. For mills producing several types of cement, we optimize for the main type. It is recommended to start first with the coarse grading.
Ball Mill. Cement Lafarge max R5% >25mm, Holcim <50mm. Standard offer from mill manufacturer is R5% >30mm; Raw Meal max R1% > 30 mm (Lafarge). Holcim "<25 – 50mm". ... In general, a mill system is set up to accept clinker of a certain size (or PSD) and if it receives anything different, then production rates are usually affected. ...
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, 5.20 m diameter, and 11.20 m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill's rotation speeds are mainly constant (14 rpm), and there is approximately a fixed one-year period of changing liners.
The ball mill is a key equipment for grinding materials, widely used in powder- making production line such as cement, silie sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with …
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
How Cement is Made (Video) 1. Mining the raw material. Limestone and clay are blasted from rock quarries by boring the rock and setting off explosives with a negligible impact of the environment, due to the modern technology employed. 2. Transporting the raw material.
Vertical roller mill for cement and slag grinding • Energy consumption: 70 % of a ball mill for cement 50 % of a ball mill for slag • Fineness: max. 4 500 cm²/g for cement max. 6 000 cm²/g for slag • Moisture required for stabilising the grinding bed – less influence on cement quality • Lowwearcosts • Throughput up to 300 t/h
