Equipment introduction
1. Current situation of granulating equipment
At present, traditional disc granulator is mainly used in the domestic ceramic sand production. The price of this kind of equipment is low, but its capacity is small, pelletization rate is low and added ingredient is required.Especially, it leads to severe dust pollution, occupies a large plant area and labor intensity is large. Under the trend of increasingly high requirements and strict management of environment and labor protection in our country, it has become an inevitable choice for the healthy development of industry to eliminate this kind of granulating equipment out of time.
In view of this, carbo corporate has pioneered in introducing german eirich rv15 granulators, achieving good economic and social benefits, drawing great attention from the domestic ceramic sand industry. However, eirich granulator is very expensive, which limits its widespread use in our country.

Brief Introduction
Ball Mill has dry and wet ways. When wet Ball Mill works, certain water and other liquid will be added into materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased.
Features
1. Large application range, simple structure and convenient maintenance.
2. Large capacity and continuous work are very obvious.
3. Barrel lining and grinding media can apply various abrasive materials.
4. Installation and adjustment are very convenient and easy to be operated.
Product Description:Â
Fixed belt conbeyor is a general-purpose using catton canvas, nylon, polyester canvas and steel cord conveyor belt components for drag cited continous convery equipment, canbewidely used in electric power, cocal, mining, iron and steel, buiding materials, chemicals, chemicals, tobacco, environmental protection, food, lightindustry, oil and many other industries. Transport variouos bluk, block or integer goods with loosedensity 500-2500kb/m3. With the feature of great traffic and climbing ability, and Small noise, easy maintenance, good inter change ability of wearing parts etc, this kind of conveyor is good for the transport system automation control. And the working environment temperature is lower than 40° C.
Belt Conveyors is widely used to transfer granular materials or packaged stuff in many industries, such as mining, metallurgical and coal etc. As per process requirement, one single belt or multiples belts can be assembled flexibly with other transferring equipments.
It should be operated under the condition with temperature range from -10 ° C. To +40 ° C. The temperature of transferred materials should be lower than +60 ° C. We also can offer belt conveyors that stand 400° C temperature.
Belt Conveyors' features:
1. Belt conveyors  is widely used for transporting material in mining, gravel field, metallurgy, building materials, chemical industry, mineral processing, coal mining and other industries.
2. Belt conveyors  is suitable for conveying material whose bulk density is less than 1.67t / cubic meter, and powder, granular, small block of low-abrasive materials that is easy to dig and bags of materials, such as coal, gravel, sand, cement, fertilizer, and grain. The sent material temperature is less than 60 °C. The form of their assembly and the length can be determined according to user' requirements.
3. Belt conveyors is widely used in underground tunnel in the mine, mine ground transportation systems, open pit mining, ore dressing plant.
4. Technical parameters of Stable performance mining rubber/PVC belt conveyor.
Production Description
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. To make gypsum as construction material, calcination process is needed, and part crystal water will be removed from gypsum. The calcined gypsum's chemical formula is CaSO4· 1/2H2O. It is widely used as raw material for gypsum board, plaster, cornice, school chalk, etc.Â
Main Technology(Nature gypsum rock)
Gypsum mine - crushing - grinding - calcining - aging -finished products (plaster of paris)
a. Crushing, Grinding Section
The forklift driver removes the gypsum ore from the quarry into the hopper in front of the crusher, and then the gypsum ore is crushed into the 20mm materials, which are later sent to the mill by the hoist to be grinded into qualified gypsum powder (raw gypsum).
b. Calcining Section
The grinded gypsum powder is lifted into gypsum calcining machine for calcination. The calcining machine uses gas heat conduction oil furnace, however, other fuels like coal, methane, LPG, diesel oil, heavy oil, etc. can also be used. Due to its low temperature, slow burning calcining mode, the stability of gypsum quality is well ensured.
c. Finished Product Packing and Storing Section
Calcined gypsum powder is lifted into the finished product silo through a hoist, where an automatic weighing and packaging machine is used to pack 50kg gypsum powder per bag for marketing or storing.
Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.Â
Materials produced using rotary kilns include:cement, lime, refractories, metakaolin,titanium dioxide,alumina,vermiculite,iron ore pellets, zinc oxide,gypsum, etc.
