For a ball mill grinding OPC to a fineness of 3200 to 3600 cm 2 /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 chaeng vertical mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement …
What is the difference between vertical mill and ball mill. Jul 03, 2018 1. The energy consumption rate of the ball mill is relatively low. At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a "granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration …
Vertical cement mill appears later than cement ball mill, which makes up for many shortcomings of cement ball mill and has more advantages. In the past, due to the limitation of cement ball mill production, many cement companies were unable to expand production scale and development was once restricted.
2019 new vertical and horizontal ball mill for chocolate. Comparing with refiner, ball mill has been improved with the advantages of low energy consumption, high productivity, low noise, super low metal content, easy to clean, one-touch operation, etc. In this way, it has shortened 8-10 times of milling time and saved 4-6 times of energy ...
Ball Mill. Applications: Mainly used in grinding operations in mining, cement, refractory, chemical and other industries. Materials: Mine ball mills are divided into dry and wet, dry type for refractory materials, cement, fertilizer, glass industry; w...
The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill are only 70%~80% of …
Vertical roller mills versus ball mills Soeren Worre Joergensen MSc, General Manager, Engineering, Grinding Technology F.L. . 2 Introduction Around 110 years ago a Danish engineer, M. Davidsen, patented a pioneering invention in France which involved a tube mill with a charge of steel balls or flint
Ball mil and vertical roller mill were used as the comminution characteristics for grinding of chromite first-order breakage kinetics in the case of ball mil and vertical roller mill in different ...
A comparison of vertical roller mill systems and ball mills systems for cement grinding has been prepa-red with reference to all these issues.3 In den letzten drei Jahren hat sich die Vertikal-Rollenmühle zur bevorzugten Mühle für das Mahlen von Rohmaterial entwickelt.
(When the ball mill grinds the wet material, due to its limited air flow through the ball mill, additional drying equipment is usually required in front of the ball mill.) 4. The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost.
Vertical and Ball mills for consistent and dependable performance, to help you get the most of your business, they designed with long-term operation in mind with a minimum need for maintenance. The purpose of the mill system is to provide a fineness to the product that will result in the required reactivity and consequently the strength producing potential of the product – …
In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed. Open the catalog to page 1
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed …

Choose vertical roller mill or ball mill in Cement grinding plant News Date: 14:30:46. Vertical roller mill has become the standard for grinding raw materials in the cement manufacturing process. but many cement producers are still favouring ball mill for cement manufacture when set up new integrated cement grinding plants.
Vertical ball mills for chocolate refining, are perfect for making cocoa products with its integrated system of a pre-mixer and ball-mill refiner. Both the Choc-1250 and Choc-1500 ball mills guarantee high production flexibility, quick payback time, and great product quality. All ball mills are energy-efficient to ensure a low product temperature.
The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, and ...
