The power consumption of these high efficiency CL and CLS Attritors is relatively low. For example, a CL machine equipped with a 150 hp motor produced 9.75 tons per hour of 95% 325 mesh limestone, this equates to a specific energy based on the mill installed motor power …
The product is then fed to the process make up tank from the LIW hopper by a feed screw. This arrangement can have a feed accuracy of +/- 0.5% once calibrated. For process requirements that are not as stringent, a simple volumetric screw feeder can be used which has a feed rate accuracy of approximately 2.5% to 5%.

power levels, particularly for the distribution of power between primary and secondary mills about a “design point.” These selected power levels and the total circuit specific energy consumption, kilowatt-hours per tonne, and expressed as “E total kWh/t” per sample, can be entered into the Mine Block Model for non-linear geo-
The fully automated ANDRITZ lime kiln package demonstrates low heat consumption, low emissions, and excellent availability. In addition to traditional fuels, the lime kiln can also burn 100% biofuels without the need for any fossil fuels with gasification or wood powder technologies.
Bond Work Index (BWI) & Hardgrove Grindability Index (HGI) tests for biomass & coal. • BWI can predict the potential for mill choking of biomass in a tube and ball mill. • HGI is a poor method of predicting grindability of biomass in vertical spindle mills. • Pellets should be composed of pre-densified particles close to the target size.
Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation. Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can ...

C. BALL MILL SLAKERS Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill slakers are generally used where: the capacity required is too large for other types of slakers.

Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 - Ca (OH)2) by mixing with water. Lime slaking is an exothermic process which generates heat and creates steam. Slaked or hydrated lime is often used in mining and process industries for raising pH or neutralising acidic solutions.
