For additional capacity, additional parallel circuits are installed. ... The normal practice is to put lime into the primary ball mills and to add xanthates at the last possible moment before flotation, while aerofloat and dithiophosphates are preferably introduced at some point in the grinding circuit, since they generally need an ...
CaO is ground into a powder in a tower mill, a spiral classifier, or a slaker. ... Because lime is very abrasive, it affects most ball and plug valves severely. A hard material cover such as stellite coating on the ball will help protect the valve against the abrasive nature of lime. ... This investment adds capacity to support battery electric ...

Vertical Ball Mill Slakers The following pages will describe each type of slaker with their advantages and disadvantages. DETENTION OR SLURRY SLAKERS Detention slaker is composed of a cylindrical or square tank with an agitator to thoroughly mix water and lime to produce lime slurry.
The limestone must be crushed and sized before calcination. The usual stone size is 2inch plus ¾inch. The sizing may vary somewhat depending upon operating practice as related to a particular lime kiln. This reaction is described by the equation: CaCO3 + Heat → CaO + CO2↑.
Rod Mill Capacity and Sizing Table. Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.
When the ball mill and the classifier are selfflow connected, the hard ore is ground to, and the suitable antisand ratio is 500700%; the ball mill and the classifier are selfflow connected, and the mediumhard ore is ground to, and the suitable reaction is The sand ratio is 250500%; the ball mill and the classifier are not ...
Advantages include: • Superior lime slaker • Ultra fine, highly reactive hydrated lime product • No grit removal required • Capable of operating in open or closed circuit configurations • Large capacity and turndown • High retention time • Minimal maintenance • Ease of operation Preselected Mills for Lime Slaking: The values listed above are typ...

Flowing Rate Control. The flow rate of materials in the cement ball mill is controlled, and the partition in the ball mill is forced to pass through the compartment; the discharge grate plate ventilation area is adjusted to select the use proper scheme, and the hollow part of the activation ring is blocked to adjust the material flow rate.

A pilotscale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of % was observed for the dry VRM compared to the wet ball mill (% for the circuit).
