PG Double Smooth Roll Crusher

 PGG-Y Roll crusher has the characteristics of simple structure, reliable working, low cost. It is widely used in large ore factory. It can also do secondary medium hard crushing. Smooth roll crusher is a kind of roll crushers. We manufacture double smooth roll crusher and quadruple roll crusher with spring adjusting or hydraulic adjusting.

PGG-Y Roll crusher is mainly the use of special wear-resistant high speed rotation teeth roll to split and broken material (conventional toothed roll crusher is a low-speed extrusion), form the mechanism of high productivity.

Crushing equipment and milling equipment has the very important application in the chemical plant, the two types of devices is mainly to the material after broken flour processing process finally used in the production. Due to the current broken equipment and there are many types of milling equipment, so in the midst of choose to use a lot of choice space. Roll crusher because its broken particle size is small, so is the first choice for many manufacturers products. Here we introduce some role characteristics of roller crusher.

The product characteristic of double roll crusher is two rollers and the surface is smooth; And another kind of roll crusher roller surface are with serrate; One of the roll surface is smooth, and the other a roller surface is with sawtooth.

Two roller surface is smooth and roller crusher for material mainly have the effect of extrusion grinding broken. The device is often used to materials such as clay, coal, clinker and limestone of finely.

Two roller surface are with sawtooth roller crusher for material mainly have the effect of splitting broken and torn, this equipment is mainly to complete the material of broken.
 A roll surface smooth and another roll with convex teeth roll crusher is mainly for material have the effect of squeezing extrusion, bending and grinding. This equipment is mainly used in crushing clay and coal.

We often use the roll crusher has the following advantages: simple structure, easy maintenance, low manufacturing cost. But the equipment production capacity is insufficient, and large equipment, need lots of space while installing area, due to the uneven wear of work roll surface, therefore need frequent repairs.
 1, PGG-Y roll crusher is mainly composed of the roller, the roller support bearings, pressure and adjusting device and driving unit and other parts.
 2, the adjustment of the discharging granularity: see working principle.
 3, driving mechanism is made up of two motors, through v-belt transmission to the Geneva wheel to drive the roller, according to the relative rotation direction. The broken material, material from the feed port, through the roller, the rolling and broken, broken after the finished product out from beneath the chassis.
 4, for the sake of safety, transmission parts should be according to the actual situation to install safety cover.
 To roll crusher for ore dressing, chemical, cement, refractories, abrasives, such as building materials in the industrial sector and finely various kinds of high, medium hardness ores and rocks, especially in the building materials industry production melon meters stone and green bean paste and other products, there are more excellent than general broken mechanical effect.

PG rollers crusher working principle
 Roll crusher can be divided into: the roller crusher, four roll crusher, toothed roll crusher, this is in accordance with the specifications to divide! The adjustment of the discharging granularity: with a wedge or gasket between the two roller adjusting device, adjusting bolt, wedge at the top of the device when the adjusting bolt will wedge pulled up, wedge rolling activity to the top from the fixed wheel, namely two roller clearance greatens, discharging granularity, when the wedge downward, activities under the action of the roller in a compression spring two rounds of smaller clearance, discharge size smaller. Gasket device is through the increase or decrease in the number of gasket to regulate the partical size or thickness, when add gasket two roll gap get bigger, when reduce the gasket two roll gap become smaller, the partical size.

The PG rollers crusher efficiency
 Roll crusher is a kind of very old and broken equipment, its structure is simple, it is mainly used for cement, silicate, and other industrial departments, finely homework of ore. Broken roller crusher is the main working mechanism, it is composed of shaft, wheel hub and roll leather. Roll skin wear degree had a great influence on the working efficiency of the roller crusher, only roll skin in good condition, crusher to achieve higher production capacity.
 It is because of the importance of roll skin, so to understand factors affecting roll wear leather and correct repair roller skin has an important significance.
 The factors affecting roll wear leather mainly include: being broken material hardness and grain size, material of roll, the roll size and the surface shape and the way of feed.
 According to these factors, the correct way is:
 (1) the material distribution even, as far as possible to reduce the roll surface in the annular groove and roll skin wear degree;
 (2) in the crusher operation, especially in the process of the coarse crushing, must pay attention to the size of the ore block, prevent to ore block is too large, causing severe vibration of the crusher and serious wear leather;
 (3) choose the roller skin with good wear resistance, can reduce the wear degree roll skin, so as to prolong the service life of roller;
 (4) the length of the feeder should be consistent with the length of the roller, to ensure uniform along the length of the roll and feed. In addition, in order to continuous feeding, the speed of the feeder should be 1 to 3 times faster than the speed of a stick.
 (5) check the size of the broken products, and should be in a certain period of time will be one of the rolls along the axial movement time, movement distance roughly equal to 1/3 of the feed particle size.
 Also, pay attention to the lubrication of the rolls, and need to be inspection hole made on the safety cover, convenient to observe the abrasion of roller skin.
