process of the modular grinding station

Need To Know: we can provide all equipment of modular mobile grinding plant. Here we just list part of representative equipment in every link.

Module 1: Dosing and Conveying System

The clinker, additives and gypsum are fed by forklift truck into the corresponding feeding silos that are installed in standardized containers.

Under the feeding silo, needle-shaped gates are installed at the discharge end of the silo, together with the dosing device, to ensure that the proportion of materials entering the mill is appropriate. After the dosing device is completed, the mixture of raw materials is collected from the dosing machine by a conveyor belt and transported to the mill.

Belt Conveyor

Module 2: Grinding and Separating

The rotations of the cement mill grind the material repeatedly. Screw conveyors and bucket elevators transport the material on the ground to the separator. Material from the elevator falls on a turntable on top of the rotor through a feed chute. The fine particles come out of the separator and enter the bag filter through the rotor. The coarse particles discharged from the rotor blades come out of the sorter through the sorting zone and return to the ball mill through two screw conveyors. The finished product leaves the separator with the airflow and is finally collected by the process filter. The dust from the bag filter enters the cement conveying system.

NOTE: Ball Mill and Vertical Cement Mill are selectable.

Module 3: Storage & Bulking

After the dust is collected by the process filter, the cement is transported to the elevator through the chute. The cement is transported from the hoist to the roof chute, where the finished cement is pumped into the cement silo by the chute fan.

Part of the cement in the cement silo is transported to the bulk loader via the screw conveyor at the bottom of the cement silo for sale in bulk. The rest is conveyed by another screw conveyor to the electric vibrating screen of the packaging unit.

Module 4: Packing

The cement is extracted from the cement silo, enters a small warehouse, and is discharged into a cement packer through a bucket elevator, air slide and conveyor.
The bagged cement packaged by the cement packaging machine will be cleaned by cleaner and weighed by electronic weighing scale. The belt conveyor sends the qualified cement bags into the stacking shed. Install cement bag counter and bag printer on tape machine.
Cement spilled during the packaging process will be returned to the packaging system through the recycling process

Cement Packer

Module 5: Tonnage Packing

Cement enters the middle bin of the packaging system and is discharged to the tonnage packer through the bottom of the bin. A flow control valve is placed at the outlet of the silo to control the flow of cement into the packer. Chain conveyors are used for loading and unloading large bags of cement.

Tonnage packaging is a technology between bulk packaging and ordinary bag packaging, which can be recycled to reduce packaging costs.

Vibrating Screen

Module 6: Fly Ash Storage

The function of this module is to store fly ash, which is then transported to the tube mill through the inclined chute. The output volume is controlled by the rotor scale.

Module 7: Watwe system

The water system is a new line and only includes a circulating cooling water system. Portable water system, fire water system, sewage system are not in our scope of supply

Water Tank

Module 8: Compressed air station

 The system provides compressed air for the new cement mill. In addition, refrigerated dryers are chosen.

Air filters also provide the purification process. The main conduit for compressed air is steel pipe. Condensate from air compressors, air filters and air containers will flow into the oil separator and then directly out.

Module 9: Electrical and automation system

Modular electrical room is a necessary part of mobile grinding plant. All panels and auxiliary equipment will be pre-installed to reduce construction period.
