PEH:Introduction to Wellhead Systems - PetroWiki
The wellhead system incorporates an 18¾-in. high-pressure wellhead housing designed for 15,000 psi and 7 million pounds end-load carrying capacity. Unlike conventional subsea wellhead systems, the big-bore high-pressure wellhead housing ( Fig. 8.30 ) is run atop 22-in. pipe (as opposed to 20-in. pipe) and has a large minimum ID bore to pass 18-in. casing.

Low Pick-up Velocity - Remember that there is a pressure gradient across the conveying system. the air velocity at one end may be 4000 ft/min and 9000 ft/min at the other. If you don't account for the pressure drop through the system, often the pick-up velocity will not be high enough to fluidize the product and the pick-up will plug.
Technical Notebook CEMENT ADDITIVES FOR VERTICAL MILLS
Mapei liquid cement additives form a system of innovative solutions for ... the use in vertical mills, optimising both mill output and cement quality. Besides high levels of energy efficiency, vertical mills have the following ... Pressure system of the grinding rollers.
Cement mills and raw mills for high throughput rates
An MVR mill may have up to six grinding rollers and up to six drive units. Thus both systems are actively redundant meaning that one or several rollers can be taken out of the system for maintenance work while mill operation continues. The same applies to the independent drive modules of the MultiDrive ®.

pressure level, which in turn will affect the total head of the pump. This article will show you how to determine the pressure anywhere in any system, which in turn will allow you to modify that pressure level and understand the impact on the pump. The system configuration in Figure 1 illustrates how drastically the pressure head can vary in a ...
Clinkerization - Cement Plant Optimization
In order to increase heat utilization in kiln system, six stage cyclones are as well installed in many cement plants. However, increasing cyclone stages beyond six does not look economic any more, as the quantum of heat saving is not significant to justify it, moreover the increased pressure drop across preheater outbalances the improvements due to additional cyclone.
Cementing Solutions - Halliburton
Our cementing specialists avert lost circulation through bridging or plugging material, rapid-set or thixotropic cement, or lightweight cement systems. Halliburton ensures the cement sheath can protect the casing, deliver zonal isolation for the life of the well, and withstand cumulative stresses from pressure testing, well testing, and stimulation treatments.
High-efficiency cement grinding - CemNet
This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.

Ball Mill Maintenance & Installation Procedure
This can be accomplished by a centralized system for two or more mills, or by an individual system for each mill. We recommend the individual system for each mill, except where six or more mills are involved, or when economy reasons may dictate otherwise. In any event oil flow to each trunnion bearing should be between 3 to 5 gallons per minute.

Baghouse - Wikipedia
Pressure drop (ΔP) is the resistance to air flow across the baghouse. A high pressure drop corresponds with a higher resistance to airflow. Pressure drop is calculated by determining the difference in total pressure at two points, typically the inlet and outlet. Filter drag is the resistance across the fabric-dust layer.
