穩(wěn)定土攪拌站分為移動(dòng)式和固定式。移動(dòng)式的拌和站各料倉帶輪胎可以牽引行走,轉(zhuǎn)場方便靈活,生產(chǎn)能力較低。固定式穩(wěn)定土攪拌站,需要用混凝土打地基,再把設(shè)備固定其上,生產(chǎn)能力高。穩(wěn)定土攪拌站專門用來拌和穩(wěn)定土穩(wěn)料的,主要拌合石灰、水泥、粉煤灰等結(jié)合料與土、砂礫或其它集料。穩(wěn)定土攪拌站經(jīng)常發(fā)生石料堵塞篩孔的事件,為操作人員帶來了不少的煩惱,下面就讓我們分析一下穩(wěn)定土攪拌站發(fā)生石料堵塞篩孔的原因,主要體現(xiàn)在以下四個(gè)地方:
The stabilized soil mixing station is divided into movable and fixed type. The moving type mixing station with the tires can be traced and walk, the transfer field is convenient and flexible, and the production capacity is low. Fixed stabilized soil mixing station, need to use concrete foundation, and then fixed the equipment, high production capacity. Stabilized soil mixing station is specially used to mix stabilized soil stabilizer, mainly mixing lime, cement, fly ash and other binding materials with soil, gravel or other aggregates. There is a lot of trouble that operators often encounter in the stabilization soil mixing station, which brings many troubles to operators. Now let's analyze the reasons for clogging of stone material in the stabilized soil mixing station, which is mainly reflected in the following four aspects.
1.含有較多的針片狀石料。
1. contains more needle like stone.
2.含有大量接近振動(dòng)篩篩孔尺寸臨界的石料顆粒。
2. contains a large number of stone particles that are close to the critical size of the sieve hole size.
3.篩孔偏小,若振動(dòng)篩上殘留稍大的石屑顆粒,就無法通過篩孔,逐漸把篩孔堵塞。
3. sieve holes are small, if a little large debris particles are retained on the sieves, the sieve holes can not be blocked and the sieve holes are gradually blocked.
4.編織篩網(wǎng)的鋼絲直徑偏粗,選用好的鋼絲既耐磨又改進(jìn),具韌性,能有效提高篩孔通過率。
The diameter of the steel wire in the 4. weave screen is coarsely. The selection of good steel wire is not only wear-resistant and improved, but also toughness. It can improve the passing rate of sieve hole effectively.
