The Hot Rolling Process

The roughing mill is made up of six independent rolling mill stands, the last four of which incorporate small vertical rolling mills called edgers. Slabs heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce so-called transfer bars suitable for finish rolling. High-pressure water-jet

2003-7-1 · The engineers of DRAISWERKE designed a horizontal mill experiment to study the effects of product flow rate, agitator tip speed and slurry concentration on residence time distribution. The trials were performed on a 10-liter horizontal mill connected to two feed tanks and fitted with a g-ray emitter and scintillation counter to measure the ...

2020-11-9 · Calculating a grinding circuit’s circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or ...

2009-8-27 · Conventional practice is to have a mean pulp residence time of about an hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10–25 grams of carbon per litre of pulp (0.5 to 1.2% by volume carbon). The carbon is retained in each reactor by means of screens having an aperture ...

2014-3-2 · The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the …

2015-1-1 · A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 –t n relationships and the mass-size balance approach.
