With the centrifugal force by rotation, milling roller wings outside presses fast-on milling rings to make comforting tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller. The raymond mill is usually used for grinding stone. Usually the Raymond with 4R 5R is chosen as stone grinding mill or mill. The final size can be up to 200 mesh. For stone quarry crushing, we advise you to design exact crushing and screening machine which is close to your situation. Gary Kelly is likely to agree. Here you can chat with our online services and what you need them. You will get your answer quickly. However, the former is faster.

Jaw crushers have many advantages, such as big reduction ratio, equal product coexistence, simple structure, reliable working condition, convenient repair and economical operation, which are widely used for mine, smelting, building material, road, railway, irrigation works, chemical and materials with cold compression strength not more than 320 MPa. The movable jaw is pivotally supported at its upper end so that the lower end of the jaw can be driven in a swinging motion towards and away from the lower end of the fixed jaw. Material to be crushed is introduced into the upper end of the crushing chamber formed between the two jaws and is crushed between the two jaws by the swinging movement of the movable jaw as the material moves downwardly through the chamber, the crushed material being discharged from the chamber at its lower end. The primary effect of the corrugations is achieved at the lower, narrow end of the crushing chamber, and in order to generate the necessary breaking the jaw faces opposed forces of the two jaws are so arranged that the peaks of the corrugations of one of the jaw faces align with the troughs of the corrugations of the other jaw face. Stone production line, the first step by vibrating feeder supply to Jaw Crusher, Impact Crusher, Jaw here immediately then crusher is playing the role that broken into large materials after Impact crusher, meet customer needs 20-60 between particles, using high speed rotating rotor plate hammer, the crushing cavity of into the materials in the produces high speed impact breakage, and make already broken material along the tangent direction in high into the crushing cavity on the other end of the counterattack board, again being broken, and then to rally from counterattack plate, plate hammer continue repeating the process.
