difference between chromite and chromate

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Stone production line

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Chromate - Structure, Properties and Uses

Chromate has several visible physical properties. Generally, it is easily soluble in water ( H2O ). The appearance of chromate is identifiable by the yellowish colour or yellow powder. Chromate is odourless when it comes to odour. Since two of the protons from chromic acid are removed to form chromate, the valency of chromate is two.Chromate has several visible physical properties.
