A Global Cement contact reported in June 2015 that only three of the six cement plants were generally operational. These were Atbara Cement, Alshamal Cement and Al Takamol Cement (ASEC). The last available figures from the Bank of Sudan reported cement production was 2.9Mt in 2013, excluding data from one plant.
The closed-circuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plants and grinding stations. There are many factors that may affect the ball mill's working efficiency and product quality during operation.

In this study, separator rejects of a closed circuit cement tube milling were dry ground in a 10-l pilot scale vertical stirred mill. Tests were done as open and closed circuit.
Ball mills for fine grinding cement clinker and additives are widely used around the world. To improve the efficiency of a ball grinding the ball mills are transferred in closed circuit with air-separators of various designs. In the article the analysis of existing grinding circuits on the basis of closed circuit ball mills made.

Howden has a long history of fans supporting the cement manufacturing process. Our centrifugal fans are engineered to meet the precise demands of each application. Our ID fans are found in: Cement mill - moving the product into the mill during grinding; Coal mill - moving the coal into the grinder
Improving the performance of a closed-circuit ball mill for cement milling, where a tumbling ball mill is integrated with a dynamic air classifier, is a complicated task because of the fully coupled interplay between the two unit operations. In cement plants, process parameters are usually set based on operators' experience gained from trial ...
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners

Then, various simulations examined the impacts of closed-circuit vs. open-circuit operation, number of compartments, and various ball size distributions. Our results suggest that integrating an air classifier into an open-circuit ball mill can increase the production rate by 15% or increase the cement-specific surface area by 13%.

This model along with the ball mill simulation model (BMSIMUL) has been used to analyse the performance of a raw mill circuit and a cement mill circuit of a 1 million by cement plant.
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.
South Sudan: B Smart, an investment company owned by son of a former Malaysian Prime Minister, plans to invest US$100m in constructing a cement plant near the capital city of Juba.The plant is targeted to be operational within 24 months pending necessary approvals, and will use limestone from Kapoeta, 275km east of Juba.
Kajo-Keji County, one of South Sudan's rich locality will soon boost of a cement factory. The area that is heavily endowed with limestone, a natural resource used for making cement has got its residents eager for a multi-million dollar investment that will soon see unemployment erased and development kicking off.
The separator reject sample from a nearby cement factory (Oyak Bolu Cement Industry) was collected for the experimental part of this study. The sampling point for the clinker grinding circuit was depicted in Fig. 2.The capacity of the cement mill during the sampling time was 130 t/h and the specific energy consumption was 32 kW h/t.
