The double-roll granulator is a special molding equipment designed by Henan Zhengkuang Machinery Co., Ltd. for powder or small particles. It is the key equipment of the ceramsite production line. It has uniform discharge, high yield, large output, compact structure, reasonable layout, and small footprint. It can meet the requirements of granulation process for sludge ceramsite, shale ceramsite, fly ash ceramsite, etc.There are 6 products according to the roller diameter and length, with an extrusion aperture of 8-16mm, granulation of 1-15 tons per hour, and an installed power of 7.5-30 kilowatts, which can meet the granulation needs of various ceramsite products.
✔ Application field
It can be widely used in chemical, petrochemical, building materials, mining, environmental protection and other industries.
✔ Suitable for Materials
1. Chemical Fertilizers & Soil Amendments
This is the primary and most classic application field for double roller granulators.
NPK Compound Fertilizers: High-density granulation of mixed powders like NPK, DAP, MAP.
Soil Conditioners: Lime powder, dolomite powder, gypsum powder, etc.
Micronutrient Fertilizers: Granulation of powder mixtures containing boron, zinc, iron, etc.
2. Metal & Non-Metallic Mineral Powders
Metallurgy Industry:
Metal Ore Fines: Iron ore powder, manganese ore powder, chromium ore powder, bauxite, etc., for subsequent smelting.
Metal Oxides: Magnesium oxide, zinc oxide, copper oxide, etc.
Refractory Materials:
Briquetting of raw materials like magnesite, bauxite, dolomite.
Ceramics & Glass Industry:
Pre-compaction of ceramic glazes, colorants, glass batch mixes.
3. Chemical Raw Materials & Pigments
Inorganic Chemicals: Sodium chloride, potassium chloride, sodium carbonate, calcium carbonate, calcium chloride, bleaching powder, catalyst supports, etc.
Pigments & Dyes: Titanium dioxide, carbon black, iron oxide pigments, etc. (Granulation reduces dust and improves flowability).
Plastic & Rubber Additives: Various fillers and additives.
4. Environmental Protection & Waste Recycling
Dust Recovery: Iron-containing dust and sludge, fly ash collected from steel plants, power plants, cement plants, etc.
Industrial Slag: Certain types of slag with specific compositions.
✔ Advantages
1. With advanced technology and stable quality, this type of roller granulator developed for the calcination characteristics of ceramsite has won unanimous praise from customers.
2. High production efficiency, high ball formation rate.The ball formation rate reaches more than 90%.
3. The discharging is uniform. The ceramsite produced by the roller granulators is uniform in size, which can meet the requirements of the ceramsite rotary kiln for the size and shape of the ball.
4. The overall operation of the equipment is stable and the noise is low. At the same time, it adopts the sealed cover to receive the material, and the site is clean and tidy, reducing the labor intensity of the workers.
