The jaws of such a jig are mounted vertically on the side walls below the retort screen. According to the direction of movement of the diaphragm, the longitudinal side diaphragm diaphragm jig, which is in line with the direction of movement of the ore stream, is called the lateral side diaphragm jawper perpendicular to the direction of movement of the ore stream. At present, the lateral side diaphragm jawper is commonly used. Since the diaphragm is disposed on the outer side wall of the tank body, it is also called a side-moving outer diaphragm jig. According to the shape of the jigging chamber, it can be divided into a rectangular jig. And trapezoidal jigs. The two types of jigs will be mainly introduced here.
There is also a jig in the middle of the two jigging chambers, also known as a side-moving inner diaphragm jig, such as a Guangdong jig, which is divided into three types, namely, A, B, and C. Although there are some advantages, Due to the cumbersome body, high production accidents, inconvenient maintenance, etc., it is rarely used, so it will not be detailed here.
1. Rectangular jig jib room has a rectangular cross section, which is simpler to manufacture than trapezoidal jig, easy to maintain, flexible in configuration, thicker in processing granularity, larger in processing capacity per unit area, and stable and reliable in operation. The rectangular jig has single row and double row, single row model is LTC-69/2, also known as Jishan-II type, double row model is 2LTG-79/4 and 2LTG-912/4, can be used in stand-alone mode. Can be used in two-machine series (double row and eight rooms). Its main manufacturers are Nanzhong and Zheng Mine. The structure, shape and installation base dimensions of the LTG69/2 jig (ie 600×900 traverse diaphragm jig) produced by Nanzhong are shown in Fig. 1. The technical parameters of the rectangular jig are shown in Table 1.
The rectangular jig has two modes of right-hand and left-type feeding. Figure 1 shows the right-hand feeding. The user should indicate the direction of the ore when ordering.
The large-grip jig developed by Mayuan in 1978 has a structure similar to that of the general double-row laterally-moving jig. Because of the coarser grain size, the combined upper and lower screens are used. The large jig model is AM-30 and its improved LTG-50 and YMT-75. The technical parameters are listed in Table 2.
The Yuba jig produced by Pinggui Machinery Factory and its technical parameters are listed in Table 3.
2. Trapezoidal Jig This is a new type of side-moving diaphragm jig designed and manufactured in China with reference to foreign similar equipment. It was promoted and used in 1966, and its structure is shown in Figure 2. The cross section of the machine is trapezoidal, which is narrowed and widened along the direction of the ore flow, and the slurry flow rate is gradually reduced, which is beneficial to the recovery of fine heavy minerals. The whole machine consists of 8 jigging rooms, divided into two columns, each column of 4 rooms. The strokes and strokes of each room can be adjusted separately to form different jigging systems. The two rows of back to back are bolted together to form a unitary structure; the structure is detachable for easy transportation and relocation. The utility model has the advantages of simple structure, convenient maintenance and reliable operation. The machine has two models (Table 1), which have been widely used in tungsten, tin , iron and manganese re-election plants. The main manufacturer is Ningde.

About Baby teether
Why do babies need to use a teether?
Because the baby's gums will be itchy during the growth of the baby's deciduous teeth. The lleviate the discomfort of the baby during the growth of the deciduous teeth.
