Product Description

High Quality Sludge Sawdust Mixed Granulation Production Line

Definition of sludge granulation line:
Sludge is mixed with other materials for multiple processing processes to produce biomass particles. It can be widely used in biomass power plant, biomass steam boiler, domestic fireplace, drying oven and biomass gasifier,etc.

Raw material:
It mainly consists of sludge or sludge with sawdust, straw and other raw material mixture of coarse fiber. And the sludge is divided into industrial sludge and domestic sludge. Industrial sludge are mainly paper sludge, industrial wastewater treatment station generated sludge, etc. Domestic sludge are mainly river sludge, sewage sludge and so on.

Brief introduction to the process:
After the sludge is dried by the paddle dryer, it is screened by the cleaning screen and finally processed by granulation. The diameter of processed finished particles is 6-10mm, which can be optional. After pelleted and cooled, it is packaged into 20-50kg/ bag by the small bags scale, easy to transport and sell. This project is 4-6 tons per hour sludge and sawdust granulation production line. The total power of the equipment is about 540kw, the workshop covers an area of 1200 square meters, including raw materials and finished products warehouse; The whole line has a compact design, reasonable structure, and meets the environmental requirements, which can be customized design according to customer requirements.

Craft features and processes introduction
Drying section: Paddle type drying system mainly includes feeding system, air preheating system, drying system, discharging system, exhaust drainage system, and control system. It is used for sludge or sludge mixture drying, paddle stirring which drys uniformly. The drying equipment is with compact structure, reasonable design, large output and other characteristics.

Cleaning equipment: MCY160×300,power: 3kw, designed output: 6T

Pelleting section: biomass pellet diameter 6-10mm optional, biomass pellets is with high calorific value, pollution-free, ash low characteristics, and can be widely used in biomass power plants, biomass steam boiler, household fireplace, drying furnace and biomass gasifier.
Pelleting equipment (4 sets) : MZLH420, main engine power 90kw, forced feeder power 0.75kw, designed to produce 1-2t/h/ set.

Cooling and packaging section: used to reduce pellet temperature and reduce pellet moisture. After cooling, pellet temperature is generally no higher than room temperature of 5ºC. After cooling, pellet moisture is about 8-10%, pellet bulk density is 650-750kg/m3. Packaging can be according to the customer's local sales needs. Choose the appropriate packaging weight to facilitate the customer to sell products. Usually there are two specifications of small bags and ton bags. Small bag packing scale packaging specifications: 20-50kg/ bag, ton bag packaging specifications: 500-1000kg/ bag.
Cooling equipment: MKLB2.5, cooling chamber volume 2.5m3, designed to produce 4-6tph.
Packing equipment: MDBLY-K, packing specification 20-50kg/ bag, packing speed 3-5 bags/minute.

According to the needs of different customers, the scheme can be optimized:
1. If necessary, buffer bins can be added between each section to replace the storage yard. The advantage is that it can improve the automation degree of production line and reduce dust pollution in the workshop; The disadvantage is that it will increase the construction cost of the production line, and because the bulk density of materials after crushing is very light, it is easy to bridge in the bins and material does not drop.
2. The packaging equipment can b
