This is called SLURRY. To obtain the SLURRY of a standard composition, the raw materials are first crushed separately using crushers for limestones and grinding mills (wet) for clays. These crushed materials are stored in separate tanks or silos.
Limestone slurry preparation system is set with one limestone slurry storage tank, in which the slurry is fed into limestone slurry supply tank through limestone slurry storage tank. Each ball mill is set with 2 ball mill system slurry recirculation pumps, one for use and one for standby, which are 4 in total.
Batch slakers, also commonly referred to as mix tanks, produce a carefully metered slurry and are best suited to applications in which slurry production rate is relatively low and where there are few (if any) changes to the quicklime quality and water sources. STT can customize batch type slakers / mix tanks with various options to meet your needs.

There is enough slurry in the limestone slurry holding tank to refill completely 24 individual tanks at the proper concentration. Complete replacement of the slurry should not be required frequently since the ammonia system will maintain the pH above the critical value.
The limestone is reduced to 6mm pieces in the crusher. The crushed limestone is then mixed with water in the Premix Chamber and fed into the CL Attritor Mill. The limestone slurry exits the CL Attritor Mill and enters the Separation Tank. Any oversized particles are pumped back into the Mill while finer slurry overflows into the Mill Product Tank.

The limestone is mixed with water during grinding in a wet mill to form limestone slurry directly, which is pumped into the hydraulic rotator for separation. The limestone slurry with qualified limestone particle size enters the limestone slurry tank and is pumped into the absorption tower by a slurry pump.

Cyclones The limestone particles of size 72 mesh from the ball mills are sent into a cyclone which stirs the slurry at a high speed of about 130 m3/hr. The fine particles remain at the top and are then sent to the storage tanks, while the heavier particles sink down are re …
One mill slurry tank and one slurry pump is supplied for one wet ball mill. The mill slurry pump will send limestone to ball mill classifier to classify big size limestone. Then, the overflow of the ball mill classifier shall go to the central slurry tank. The agitator is provided to keep the slurry solids in suspension during tank usage. 3.
Limestone Slurry Hold Tank (V-105) and Agitator (A-102) The limestone slurry hold tank will be a 30 ft diameter -21- ------- limestone. Each mill will be capable of continuous flow of 32,000 Ib per hr of limestone solids, in a slurry with water,/ (60 per cent solids concentration, total flow rate 54,000 Ib per hr).
Limestone reactivity is greatly influenced by particle size. A typical method of preparing limestone slurry is to grind the raw limestone with water in …
A limestone slurry grinding circuit for a flue gas desulfurization system, said grinding circuit comprising a a mill for grinding limestone in water to form a limestone particle slurry, said mill having a feed inlet and slurry outlet, b means to direct the limestone particle slurry from the mill to a slurry sump tank in which the slurry is ...
Limestone can be directly processed into aggregated rock and burnt into unslaked lime which becomes slaked lime after its moisture & water absorption. The main content of slaked lime is Ca (OH)2. Slaked lime can be blended into lime slurry, lime putty, lime mortar etc. Which can be used as coating material, brick & tile adhesive.
Pre-Ground Limestone Injection • Dry, pre-ground limestone feed options −Pneumatic injection into reaction tank below slurry level −Pre-slurry in small tank • Advantages −Low capital cost (i.e. no ball mills, auxiliary equipment, buildings, etc.) −Less equipment to maintain • Disadvantages −Higher delivered cost

D. Horizontal Ball Mill Slakers E. Vertical Ball Mill Slakers The following pages will describe each type of slaker with their advantages and disadvantages. A. DETENTION OR SLURRY SLAKERS A Detention slaker is composed of a cylindrical or square tank with an agitator to thoroughly mix water and lime to produce lime slurry.
The resulting mill slurry, containing both finely and coarsely ground limestone, is transferred to the corresponding storage tank and temporarily stored in the presence of water. To avoid spray line clogging by coarsely ground limestone, a classifier is used to ensure that only finely ground limestone is fed into the scrubber, and the limestone ...

Agitators shall be supplied in tanks and vessels to prevent caking and settlement of particles out of the slurry, e.g. in the absorber vessel, limestone mill recycle tanks, limestone slurry tank, Auxiliary Absorbent tank, and sumps etc. 2. All agitators shall be designed for continuous operation unless otherwise specified.
Limestone slurry transport provided four slurry pumps, two, two standby. Each is provided a desulfurization unit limestone slurry transfer circuit. For the limestone slurry mixing, to prevent precipitation, fouling, which are installed in the slurry tank slurry agitator. 2. Smoke System
The module conveys conditioned limestone powder from a surge hopper located below the silo discharge and slurries the powder with water on a single pass to 30%+ solids. The finished slurry is continuously pumped from the in-line slurry tank to one or more slurry storage tanks.
In the wet process, the slurry contains 35% to 50% water. That is why, to dry the slurry more fuel is required. The calcareous materials such as limestone are crushed and stored in silos or storage tanks. the argillaceous material such as clay is thoroughly mixed with water in a wash mill. The washed clay is then stored in basins.

The limestone wet flue gas desulfurization process is generally operated under the condition of a pH value of less than 6.2, which can increase the solubility of limestone. When the pH value is between 5.5 and 6.0, most of the SO2 absorbed by the circulating slurry exists in the form of HSO3- and cannot be combined with H+. Because lime is ...
