slaking and limestone grinding applications. These units have the ability to produce a very fine grind at a much lower power consumption for the same throughput as conventional mills with a range of units from 0.4kw to 1,120kw installed power.

In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency.

Union Process, Inc., of Akron, Ohio, and Chemco Systems, L.P., of Monongahela, Pennsylvania, have jointly developed a lime slaking system that takes advantage of the efficiency of a Chemco detention slaker and Union Process C20 Attritor Ball Mill to produce a high quality lime slurry and eliminate grit disposal and its associated problems.

Vertical Ball Mills. When lime or water quality is poor and/or when lime consumption rates are high, STT designs slaking systems utilizing a vertical ball mill. The total grinding process of a vertical ball mill utilizes all residual reaction value, virtually eliminates grit disposal problems, and significantly improves lime usage efficiency.

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables 'the old fashion way'.

vertical ball mill slakers. Vertical ball mill slakers are comparable to horizontal ball mills in cost however have much better turndown capability and consume less energy In addition the temperature probe is located in the reaction zone for this type of mill so a vertical ball mill can be optimized to maximize lime reactivity and reduce overall chemical consumption.

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.

Literature showed that using VRM instead of a ball mill could reduce Zinc grinding power consumption from 20.11 to 11.11 kWh/t of raw materials (kWh/1000 kg) . In another research, Gerold et al. reported that in copper slag grinding, 22.9% and 34.4% of airflow and power were saved by using the VRM, respectively .

EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies below 75 µm to ball

When ore property data and SAG specific energy predictions are combined with mill power, they provide a useful tool for evaluating the throughput of a given mill and, therefore, circuit.

JKSimMet was used to fit a model to site DCS data. Thus, there was considerable scope to reduce the ball-mill power consumption by using smaller ball-mill grinding media. However, for a final grind of 75 μm, the reported power values for both HPGR-ball mill and SABC circuits were based on JKSimMet modeling alone.

The ball mill specific power consumption E ball is determined by deducting a cone crushing component from the Bond/Rowland E ssbm specific power consumption. See the base formulae in the Bond SSBM model. where CF is the Essbm calibration factor (in …

includes the separation tank, mill recirculating pump, mill product tank, hydrocyclone, hydrocyclone feed pump and all necessary controls. Due to the CL Attritor's high efficiency, the power consumption for this mill is 50% less compared to conventional ball mills of a similar size. This results in substantially lower operating costs.

Material is fed into the gap between the rolls, and the crushed material leaves as a compacted cake. The energy consumption is 2.5–3.5 kWh/t and about 10 kWh/t when recycling of the material is used. The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill.

• low specific power consumption: – reduce variability in the load parameters (mill table power, mill differential pressure, mill fan power) – reduce specific power (mill fan and mill table). Control technology and structure Traditional PID single input/single output control has some inherent disadvantages in that each loop operates where ...

Lime dosing via this method is based on the rationale that the ball mill provides sufficient agitation and residence time to achieve slaking (i.e. hydration) of the quicklime into Ca(OH) 2. A similar dosing method is applied to gold heap leaching operations where dry quicklime is dosed directly from a silo, via a screw feeder, onto the ore on ...
