4 types of stone crushers' maintenance and efficient improvement | fote machinery

There are different types of stone crushers in mining industry such as jaw crusher, cone crusher, impact crusher, and sand making machine. This article will tell you how to maintain the 4 types of rock crushers and how to efficicently improve their performance.

Many stone crusher operators have a common coception that is "don't-fix-it-if-it-isn't-broke". They may want to save cost at the begining while the consequence is that they have to spend more money on repair and face interuption on production. That's why I always say that preventive and predictive is very important for all types of stone crusher.

Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.

Predictive refers to mornitoring the condition of crusher when it is running. By some maintenance tools such as lubricating oil temperature sensors, lubricating oil filter condition indicator, you can timely draw the machine data so that making a comparison between the real situation and normal state. Predictive can help you find problem early then timely removing thers issues before demage occuring.

Ractive means that even if your crushers have got problems, as long as you adopt correct solutions to respond, you still can get your machine back to normal. Next, I'll introduce important skills to maintain your equipment.

The cone crusher in the secondary or tertiary crushing proccess often fractures medium-hard or hard rocks like pebble, quartz, granite, etc. It is easy to get premature crusher failure, if operators cannot make a correct and timely inspection and maintenance.

Mantle in moveable cone and concave is fixed cone. Due to directly contacting with rock materials, the two wear parts need frequent maintenance and protection. So operators have to know the preparations and maintaining skills.

The working principle of impact crusher is that the spinning rotor under the driving of the motor can genetate strong impact force which make blow bars crush stone material into small pieces. Then the crushed material would be thrown by hammers towards, which makes another crushing process "stone to stone".

The sand making machine is also known as the vertical shaft impact crusher. Its working mode is that the material falls vertically from the upper part of the machine into the high-speed rotating impeller. The impeller is one of the important parts of the sand making machine, and it is also the most vulnerable part.

After the materials collide with each other, they will be pulverized and smashed between the impeller for multiple times and discharged from the lower part. The materials crushed by the device have an excellent particle size and are suitable for aggregate shaping, artificial sand making and highway construction.

In the face of such a dazzling market, how to choose the production equipment suitable for users' actual needs among the numerous equipment brands of many machinery manufacturers is a big problem for many large and small enterprises.

factors affecting the crushing efficiency of the crusher | quarrying & aggregates

During the production process of rock crusher, the crushing efficiency is not only affected by its performance, but also affected by several other factors. Knowing the factors affect stone crusher crushing efficiency can help investors improve the production rate. In the following part, we focus on factors affect the production efficiency of rock crusher.

Different types of crushers have different working principles. The physical properties like hardness and fragility of raw material will all affect the crushing efficiency of a stone crusher. If we adopt the proper type of crusher to process proper raw material, the crushing efficiency of the crusher is high. On the contrary, while being used to crush raw materials with high hardness or viscous material, the crushing efficiency will reduce.

If the moisture content of raw material is too high, it will also reduce the crushing efficiency of a rock crusher. This is because during the crushing process, too wet raw materials will adhere to the crushing cavity and other parts, reducing the volume of the crushing cavity and the crushing efficiency.

During the working process of stone crusher, crushing cavity directly contact raw materials, making it the main wear-resistant part in the crusher. In different crushers, the crushing cavities are formed by different parts. In jaw crusher, the crushing cavity is formed by fixed jaw plate and movable jaw plate and in cone crusher, the crushing cavity is formed by concave and mantle.

If the crushing cavity is seriously damaged, the crushing force will reduce, which will lead to the reduction of crushing efficiency. Besides, the abrasion of the crushing cavity will also make the final products size increases, affecting the crushing effect.

The production efficiency of the rock crusher has great influence on the efficiency of the whole crushing plant. Operators should pay attention to the above 4 factors during the working process of rock crusher and solve the problems in time in order to improve the production efficiency.

Stone chips are one of the main construction materials along with bricks, sand, cement, and steel. Generally, you can segregate the crushed stone into various sizes like 35mm, 20mm, 12mm, etc for different uses. Crushed stone aggregates are essential for the construction of roads, bridges, housing, industrial building construction.

Additionally, it is an essential item for other cement-based products. The list includes RCC pipes, PSC poles, pre moulded slabs, frames, and beams, etc for fabrication. A stone crusher plant is a profitable venture for new entrepreneurs. The demand for quality stone chips is increasing day-by-day.

All the building constructions whether it is housing or industrial construction activities requires crushed stone. Crushed stone is also required for cement based products like RCC pipes, PSC poles, cement concrete hollow blocks, precast cement concrete slabs, well rings, window & door frames and road laying. The demand for crushed stone will continue to grow with the growth of its user industry.

One of the most particular and general but most important materials used for making concrete is stone chips. These are used as filler with binding materials in the production of concrete. Crushed stones occupy about 72-75% of the volume of concrete and they greatly influence the strength of concrete.

Land and machinery are the major fixed cost investment. Major working capital costs are raw material, manpower, and utilities. Under the PMEGP scheme, you can get the subsidy from the banks. In the project funding, there must be a percentage of promoters allocation of the fund. Bank can ask for collateral security deposit also on the loan amount.

Stone crusher plants are available in two major types namely (a) stationary (b) portable or mobile. However, you can establish stationary crushers at quarry heads. Mainly, at the construction site, you can use the portable crushers. Here we have explained the stationary stone crusher plant details.

First of all, break the big stone boulders to smaller size manually. Then it isfed to the stone crusher. The crusher can accept the stone size of 175mm. Stone crushing is the two-stage process. In the first stage, crush the 175mm stone to about 50mm.

Thereafter, fit the crusher with a conversion kit to enable granulation of 5 to 20mm. Then screen the crushed material by the rotary screen. Unit location is a major factor for stone crusher plant business.
