Limestone production line equipment sales
The limestone processing plant
Qualified limestone was hidden in the storage bag, charging material by installing position of up and down the two store content bag charge level indicator control, and then through the tremie pipe, the limestone will be evenly distributed to each room of preheater.
The limestone from 900 ℃ to 900 ℃ kiln gas preheater heating. Limestone is close to 30% is parsed and 70% is through hydraulic push rod, limestone into the rotary kiln
Rotary kiln will be roasted and decomposed into CaO and CO2. The lime or limestone solution will enter from The cooler and after discharge after cooling to cooler. The exhaust gas under 100 ℃, mixed with cold air, and then enter The cloth bag dust catcher, through The induced draft fan, and then into The chimney through The exhaust fan. Lime emissions from the cooler will be sent to you by vibrating feeder, bucket conveyor, bucket elevator, belt conveyor into the lime storage. According to the requirements of customers, we will confirm, if you need to identify and other necessary procedures.
In all the lime roasting system, in accordance with different volume, the cooler can be divided into several preheater, mixture of preheater each equipped with a set of hydraulic drive device, and also equipped with automatic control system, in order to send the data to the PLC control platform, is in the central control room, realize the centralized control. The control system has a high degree of automation, but also can achieve a single point of control, all of these make the production process more convenient, fast.
XSM machinery pay more attention to the working process of the science and technology of system balance. We’ve made a lot of ways, such as a flat system, which makes the material and fuel becomes more reasonable supporting system, lowering the cost of the fuel energy and investment saving some improvements.
Limestone production line processing equipment
There are two big projects limestone production line here. One project is no emission, grind powder directly, it will produce coarse whiting, so also known as coarse whiting lines. Other project mainly use carbonizatin method, that is, high temperature fire, should by calcination rotary kiln. Mixed according to certain proportion, and through high temperature calcination, absorb water and carbon dioxide carbide limestone and coal white, then through the centrifugal dehydration, dry, cool, crushing and screening, you will get a good product, namely the precipitation of calcium carbonate. This production line is often referred to as the precipitation of calcium carbonate plant.
Main processing equipment including elevator, counterattack crusher (optional), mill, classifier, packing machine, dust collector. Customers can refer to our lien and limestone gypsum powder production line, also can check the Raymond mill commissioning video, can have a further understanding XSM mechanical polishing technology.
Project phase ii
Main processing equipment including crusher (on the left the first working equipment), slow (raw material grinding, dosing is the first step) before entering the mill, rotary kiln (should be equipped with a preheater and cooler).
Introduction of limestone
The main composition of the limestone for calcium carbonate (CaCO3). Lime and limestone are widely used as building materials, they are the basic raw material in many industrial fields. Limestone can be processed into gathering of rock and coal directly be quick lime. Lime can be divided into two types, namely, quicklime and hydrated lime. Quick lime mainly of calcium oxide, it always appears as block. Pure lime is white and not pure lime light gray or pale yellow. When adding moisture absorption or water, will become the slaked lime calcium lime, lime hydrate is also called the slaked lime, its main ingredients for the Ca (OH) 2. Once the slaked lime mixed with lime slurry, lime plaster, lime mortar, etc., it can be used as coating material and ceramic tile adhesive.
