Project General Contracting Service
To minimize the project construction period and reduce the customer’s investment, this pulverized coal preparation project adopts the project general contracting service. The project general contracting service is a “turnkey” service project designed by SBM especially for the customer’s production convenience needs. This service runs through all projects steps, including site terrain environment survey and investigation, production line process design, raw material inspection and testing, finished product requirement analysis, customer investment cost budget, and equipment installation and commissioning, which can prevent the interruption of operation and delay of production due to customer’s special causes such as inadequate preparation of construction materials and labor shortage. The project general contracting service realized the maximum production convenience for the customer, met the customer’s need of urgent production schedule, and won the high appraisal from the Shandong customer.
To promote the operation convenience of pulverized coal production line, this production line adopts the unique two-step (baking and pulverizing) operation method. The two-step pulverized coal preparation system is a solution with baking and pulverizing separated. With relatively low grinding chamber temperature, it’s the unique pulverized coal production process of MTW European Grinder. This process system features relative simple and easy control and can remarkably improve the safety performance of the production line.

The MTW series European Grinder adopts multiple advanced technologies, including integral bevel gear drive, internal thin oil lubrication system, and oil temperature online measurement, and boasts multiple proprietary patented technological property rights, characterized by small occupation area, low comprehensive investment, low operating cost, high efficiency, and environmental protection.
High Safety and Environmental-Friendliness
To guarantee the fire-proof and explosion-proof safety performance during the pulverized coal production, the production line is fitted with nitrogen system, CO, and CO2 fire extinguishing system to guarantee running safety and stability of equipment to the maximum extent.
Meanwhile, the effective measures are taken to strictly control the dust concentration of exhaust gas within the national specified range. The production line adopts the pulse dust collector manufactured with advanced technologies to reduce the influence on the surrounding environment to the maximum extent.
