Recently, seven departments including the Binzhou Municipal Development and Reform Commission and the Municipal Bureau of Finance jointly issued the "Opinions on Accelerating the Development and Promotion of Grain Drying Machinery and Equipment". It is pointed out that by the end of 2017, Binzhou City has achieved more than one grain drying machinery manufacturing enterprise and established grain. There are 7 drying mechanization demonstration bases, and 160 sets of grain drying machinery and equipment. The annual mechanization of grain drying is 220,000 tons, which solves the problem of grain drying for some grain-scale planters.
The "Opinions" pointed out that grain drying equipment is the focus of purchase subsidies for agricultural machinery. Actively support the research and development, production and promotion of grain drying equipment. All departments formed a joint effort to promote the research, development and promotion of grain drying machinery and equipment.
China 33mm Split Set Bolt,Friction Rock Bolt,Pipe Joint Bolt supplier & manufacturer, offer low price, high quality Mining Bolt,Split Set Rock Bolts, etc.
33mm Split set bolt is also called "Split Set Stabilizer". It was successfully developed by American Professor Scott in the early 1970s. It was used as a patented product by Ingersoll Rand for mining support. In the early 1980s, the Beijing Institute of Well Construction conducted exploratory tests on slotted pipe anchors in the laboratory and achieved good results. Later, it was gradually promoted and applied in the coal system.
33mm Split set bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force.
33mm Split set bolt has good supporting effect. Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.
