With the centrifugal force by rotation, milling roller wings outside presses fast on milling rings to make relieving 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 stone grinding. Usually the Raymond mill with 4R or 5R is chosen as stone grinding mill. The final size can be up to 200 mesh.

Stone production lines are divided into two types, gravel production line and sand production line. Of course, if the classification is different, the equipment configuration for production line must be different. The main equipments of gravel production line is crushing devices, but for sand production line it is making sand equipments. According to the hardness of the broken materials, the stone production line can be divided into one-step forming and secondary crushing stone production line. And sand production line is combined by vibrating feeder, jaw crusher, sand making machine, vibrating screen and rubber belt conveyer equipment etc.

With the recent new TCC Group have started construction sand and gravel production line in Guizhou, Sichuan, more and more customers to consult the general contracting project of Zhengzhou Hongxing gravel consulted a number of customers for the recentopen field use of medium-sized stone equipment, with more than ten years of aggregate production line equipment and production process configuration experience ZhengzhouRedstar engineering Co., Ltd. sand and gravel project Department given the following recommendations: To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like rotary kiln, Henan Hongxing is always doing the best in products and service.rock cone crusher:http://www.hxjq-crusher.com/8.html

1. Choose rich experience with the configuration of equipment manufacturers

Generally sred staring, the configuration of the sand and gravel production line, mainly composed of feeder, jaw crusher, impact crusher, conveyor belts, round vibrating screen and other equipment, and specific production process manufacturers rich device configuration experience in order to develop, because the configuration of the production process to consider many factors, such as material properties, topography, production capacity, angle and length of the belt conveyor, and many years of complete sets of sandstone aggregate production equipment configuration experience in the production process in the late will appear broken equipment capacity cannot take full advantage of the lack of transmission capacity, feed to plug a series of questions.

2, field trips related to aggregate production line.

All have many years experience of the manufacturers of aggregate production line configuration must have already built the production line, the choice of the production equipment of the quarry, better go to the manufacturers of construction sand and gravel production line to visit, especially in production and material and similar sand production line, on the one hand, to choose their own devices have a reference, on the other hand on broken equipment manufacturers will want to select the configuration of the production line quality checks.
