Raw material grinding plants
The requirements determine the mill type.
Shibang offers a comprehensive range of grinding processes. However, the right choice of grinding plant for the respective application is governed by numerous criteria.
Apart from the raw material properties and the required throughput capacity, the capital investment, operating costs and availability are particularly important factors.
Available with us is a highly functional range of grinding plants (spice grinding machines) that is manufactured using superior quality raw material.
The tube mill is a proven, simple and easy to maintain machine, which also involves the lowest capital cost.
Its main disadvantages are significantly higher energy con sumption compared to other grinding processes and low material drying capability.
The POLYCOM high-pressure grinding roll has the lowest energy requirement and can be readily combined with other grinding processes, to achieve great increases in output. However, the POLYCOM also has a limited material drying capability.
In about 85 percent of all raw material grinding applications the roller mill is nowadays used. It offers the advantage of combining three work operations -grinding, drying and separating – in one compact unit. The design of the DOROL double-roller mill, well-known from over 250 installations all around the world, has been advanced. The result is the QUADROPOL, which offers high throughput rates, low construction size and high availability. The QUADRO-POl has four grinding rollers, whose bearings are located outside the mill and are thus protected against dust and high temperature. The mill can be automatically switched over from 4 to 2 roller operation, which provides great flexibility and the ability to adapt to changes in raw meal requirement. For maintenance purposes, each pair of opposite grinding rollers can be pivoted out of the mill housing. The two roller units remaining in the mill then take over the comminution process, which is a precondition for online operation with an uninterrupted flow of material from the mill into the kiln.
Good accessibility, easy maintenance and the possibility to change over to partial-load operation with 2 roller units without interrupting operation complete the convincing QUADROPOL concept.
The POLYCOM can be used as a primary mill, or in combination with, for instance, tube mills or as an autonomous finishing mill. The more grinding work is shifted to the high-pressure grinding roll, the higher is the energy saving compared to others systems.
The DOROL double-roller mill is the standard roller mill for grinding a very broad range of materials including coal, blast furnace slag and clinker. This mill type has been constantly refined and optimised over the years, and has thus achieved an excellent level of efficiency and reliability.
Simple plant concept and low capital costs are characteristic for the air-swept tube mill.
