Dolomite Grinding Unit In USA

Dolomite is a kind of carbonate minerals which can be divided into iron dolomite and manganese dolomite. It is the main component of dolostone and dolomitic limestone. Dolomite can be used as rholite for making basic refractory and blast furnace iron and also be used as the ingredient to make glass and ceramics. All in all, dolomite is widely used in building materials, ceramics, glass and fireproof, chemical, agriculture, environment protection and energy saving fields and so on.

In 2012, an American customer contacted our company and said that he wanted to set up a complete dolomite grinding unit in the USA. After communication, we learned that he needed dolomite powder with 600mesh and the capacity with 10tph. Confirming the input size of the dolomite and some other factors, our engineer designed a plant consisted of PE250*400 jaw crusher, vibrating screen and LUM1125 ultrafine vertical roller mill. The capacity range of LUM1125 is 5-12tph which is totally suitable for the customer. And the final size of this mill is about 400-625mesh, also suitable for him. The customer was very pleased with this design and finally decided to corporate with ZENITH.

The whole working process is: firstly, the jaw crusher will crush the bulk dolomite into small particles. And then the particles will be separated and graded by the vibrating screen into different sizes. The parts with required sizes will enter the grinding mill for grinding while others will be sent back to the jaw crusher for re-crushing.

As we know, the common used dolomite sizes are: 6-10mesh, 10-20mesh, 20-40mesh, 40-80mesh, 80-120mesh, 140mesh, 325mesh, 600mesh, 1000mesh, 1600mesh. ZENITH can provide various grinding mills to process dolomite into these sizes, such as vertical grinding mill, ultrafine mill, trapezium mill, ball mill and Raymond mill etc. The fineness of SCM ultrafine mill can reach to 2500mesh, particularly suitable for super fine powder making. If the customer need fine powder like 1000mesh and 1600mesh, we suggest this ultrafine mill. Our engineer will recommend suitable model according to the requirements of the customers.
