High manganese steel liner for vertical shaft impact crushing machine-made sand process
May 11, 2021
Using high-speed rotating materials to crush each other and friction between materials to crush.
The vertical shaft impact crusher can be divided into "stone hitting iron" and "stone hitting stone" according to its working mode: the vertical shaft impact crushing impeller rotates at a high speed driven by the motor, throwing the material from the impeller flow path and hitting it on the counterattack plate. A vertical shaft impact crusher equipped with a counterattack plate is called "stone hitting iron"; if the counterattack plate is not installed, the material thrown by the impeller directly hits the naturally formed material lining. This situation is called "stone hitting stone" .
The sand production rate of “stone hitting iron” is higher than that of “stone hitting stone”. Process flow: The vertical shaft crushing sand making process has two methods: open-circuit production and closed-circuit production, and each method is divided into dry, wet and semi-dry production. Dry production has high sand yield and stone powder content, but serious dust pollution. Wet and semi-dry production have low sand yield and easy dust control. The choice of dry and wet production methods requires comprehensive consideration of many factors.
When the main project is mainly roller compacted concrete, dry production is more appropriate. Parallel dust collectors and dust collectors can be used to remove dust from the main dust points, and the vertical shaft broken feed silo can be closed. However, for large-scale artificial sand aggregate systems whose main project is normal concrete, wet production should be adopted. Under the premise of controlling the wear resistance, toughness and hardness of the product, the hammer head of the hammer crusher produced by Xinxiang Xinnai Casting Manufacturing Co., Ltd. strengthens the strict management of the production process, reduces the price increase of the product, and effectively guarantees the customer cost Increased, the high chromium composite hammers, alloy hammers, high chromium iron castings, wear-resistant hammers, and mill linings produced by Xinnai Castings have been recognized by customers and have received friendly feedback from many customers. Xinnai Castings are high-quality Choice, honest and trustworthy operation, strict quality management, and serve customers wholeheartedly.
